User questions & answers

Question:	Can i use this with 2 solar panels (Pmax 20 each)? And will it gove power to the power grid with only 2 panels 20watts each
Answer:	DC 10.8-30Vb version can be used for Voc 20V-24V. So your panel voltage is in line. But the power is too low to start the inverter. The minimum power is 200W. Up to 1100W
Question:	How many 100 W solar panel's do I need to run this system at maximum
Answer:	Hi, maximum 1200W input, you can use 12PCS 100W solar panel in parallel. Recommended 18V Solar Panel, Vmp: 18-21V, Voc: 20-24V
Question:	I have hooked up this inverter to 8 100watt panels. using 8 gage wiring. and at best all im getting out of this inverter is 300 watts. why
Answer:	wonderful day. Let's help you solve this problem. 1: Only 75-85% conversion of panel and inverter normally (many factors, such as panel aging) 2: You need to test 800W solar panels. The actual number of watts output. 3: Because 800W output is the effect of the laboratory. Usually in our environment. The sun can not be 90 ° above the panel. 4: Inverter output power. Requires panel input. If the panel is actually only 300W-400W input. That inverter can not output 800W.
Question:	I am using 12 voilt 100 watt panels. What is the minimum amount of panels I need to run this unit
Answer:	This is another old question and answer presented here for more than one product making the answer inaccurate. Look at the DC output voltage on the solar panel you have. One 100 watt solar panel will be about 21.6 volt open circuit (Voc) and about 17.9 volts optimum operating voltage (Vmp). Now the grid tie inverters will show you a DC input range. One will be about DC10.8-30V and the other will be about DC20-45V. To answer the question if you buy the grid tie inverter with the input range of 10.8 to 30 volts you can use one 100 watt solar panel (VOC of 21.6 solar must be in the input range of the inverter). One 100 watt solar panel is the minimum panels. This is extra information to help you understand. Wiring two 100 watt solar panels in series doubles the VOC and VMP output. If the 100 watt solar panels are wired in series you can see that doubling the VOC (43.2 vdc) and VMP (35.8 vdc) will require the other grid tie inverter that has an input range of DC 20 to 45 volts. I hope this helps to understand it better.

User questions & answers

Question:	Does this have automatic shut off if i loose power from the actual grid
Answer:	You can try by unplug the 110v while the panels still connected to it. If it shuts off then you have the answer.
Question:	how many panels
Answer:	FYI I tried connecting up exactly 1000 watts in panels to a 1000 watt inverter, but I usually get ~800 watts in power (measured) to the inverter and that becomes converted to ~650 watts AC. That seemed low at first to me, yet it makes sense in that each device has ~80% efficiency. So that made me ask this question to several OEMs: "Does the 1000W rating of the inverter mean it can put out 1000W AC (with sufficient input like 1100W DC), or is it max 1000W DC (leading to ~800W AC max)?" Most have responded "It can produce 1000W AC, yet we don't suggest loading it 100% like that." So based on my experience above I'd be comfortable putting ~1200 watts in panels on a 1000W unit that will lead to ~1000W DC input and ~800W output most of the time. Otherwise you can connect up any lesser quantity and expect the lesser AC outputs (as well as reduced output from limiter functions if on that model).
Question:	are there inverters that will power both sides of my breaker panel(load sharing) or do should I need 2 and hook all panels to both inverters
Answer:	Multi point question. Yes there are inverters that have split phase output. That would answer the first part of your question. Those s[lit phase inverters will power both L1 and L2 of your breaker panel. The other part of your question has more than one answer. If these single phase (120V) inverters are stackable and grid tie capable, then yes, two of them could act like a split phase inverter and power both lines of your breaker panel. But, the input sides of the inverters, coming from the solar panels, have to be isolated. Do not tie all the solar panels to both inverters. Tie half of the panels to one inverter and the other half to the second inverter. Full disclosure, I don't have any of these inverters and have no affiliation with the company making or selling them. I am a certified solar power systems engineer and system designer and just want to offer guidance where I think I can be helpful.
Question:	Can a battery bank be hooked up to the dc input as the 22-65vdc model
Answer:	I have mine running from a 48v battery bank with the battery volts limit set at 42 and the reboot at 48. I have also set the power limit to 500w. To keep the battery charge I'm using a 60 amp solar charge controller

Customer Questions & Answers

Q: Does the current limiter have current limit?

A: The current below 4.5A will make the current limiter less sensitive. It is recommended to use it at 4.5-9A.

Q: Does the buckle of the current limiter require wires?

A: It is recommended to use the correct diameter restrictor wire. If the wire is too thin, please loop the wire inside the current limiter buckle to reach the proper size of the buckle. If the wire is too thick, the current limiter buckle cannot be buckled, and the current limiter will not work.

Q: Why does the grid-tie inverter not work or stop after working for a while?

A: When the power of the load in the working state is too low, the grid-tie inverter will not be able to recognize the load, so the inverter cannot be started. After starting the grid-tie inverter, if the power of the working load is lower than 100w, the inverter may stop working.

We recommend that when using 1000w grid tie inverter, ensure that the load power in the working state is not less than 100w

User questions & answers

Question:	Does a blinking green light indicate normal operation
Answer:	Yes
Question:	Is it 220volts output
Answer:	They have multiple models available, like one intended for 10.8-30V input or another 22-50V. They also have the choice of 110V output or 220V. So select the one you want (the selection is between the pictures and prices near the top of the page).
Question:	Does it serve as an off grid
Answer:	Sorry, inverters can only be "Grid-tied" where it will detect grid power and follow it in sync, or it's an "Off-grid" inverter creating it's own power from batteries. This is "Grid-tied".
Question:	I have this connected to 4 - 24 volt 260 watt solar panels in parallel. Connected to 110v outlet, why only push 530 watts
Answer:	The seller has a formula on the web page that with your 4 panels comes down to: 1040 watts*.8*.9=748 watts as the maximum you would get. That is using 80% panel efficiency and 90% inverter efficiency from the seller. I don't understand the answer that says you should be getting 900 watts. That's 86% efficiency which exceeds the solar panel efficiency alone. That is just wrong. Maybe the more expensive micro inverters would achieve the 748 watts for you. I have never forked out the money for one yet but I will just to see. I have 50 solar panels in the back with various cheap grid tie inverters like this one and have been playing with solar for about 5 years. I can never get much better than 50 to 60% and I have tried everything. Well, I did spray water on a 1700 watts of panels to cool them and achieved just over 1100 watts on a clear sunny day but that isn't practical.

User questions & answers

Question:	Can you put these outside under the roof eave? It's dry, I'm just concerned about heat and dust
Answer:	Dust, heat and moisture are likely reasons not to mount these outdoors, yet it's up to you on how bad you think those could be.
Question:	Can you install multiple inverters to the same circuit
Answer:	You likely can run multiple inverters (like 2) on the same circuit, but realize that if you were getting 1000 watts from each at 120V (or 8 amps each) then 16 amps can be over a 15 amp circuit rating. There's not a great chance of you getting a full 1000 watts (unless you have ~1200 watts in panels feeding each), so that risk is pretty low. Another item to think about is where you have the inverter plugged in on your circuits wiring (if you know how your house is wired which I hope you do). Lets say you have 4 outlets wired in the garage on one circuit and I'll call them outlet 1 nearest to the breaker box and outlet 4 furthest away with them all wired down the same chain of wires. Some may think of plugging in the inverter to outlet 1 so the energy goes the shortest distance back to the breaker box, but that may not be the best choice. If you were to have the inverter feeding 8 amps into outlet 1 and began running tools (like an air compressor and power saw) on outlets 2 & 3, you could be pulling 25 amps down the wires between outlet 1 and 2 without the breaker popping (since 8 comes from the inverter and ~17 comes from the grid staying under a 20 amp breaker limit at the box). Such is pushing the limits on the wires where they could be heating up in the walls without you realizing it. Yet if you were to have the same tools running but the inverter plugged into outlet 4 (at the end of the chain), then you'd only have the 17 amps coming from the breaker box down to outlet 2, say 12 amps going to the tool on outlet 2 means only 5 amps goes down the wire between outlet 2 and 3, and the tool at outlet 3 gets 13 amps (8 from the inverter and 5 from grid combined). In this situation no wire has over 20 amps thru it and if the inverter alone is feeding power back thru everything it's only the 8 amps (again well under the 20 amp rating). So that may be something to consider about where you plug it in and why since multiple power sources can put the wires under higher loads like that (and feeding one source at each end is safer than all from one end of the wire chain).
Question:	Can I hook it up to a battery bank
Answer:	You can connect to any DC source, but these are intended for going direct to solar panels. The MPPT feature is literally trying to collect "maximum power" and convert everything it can to AC constantly, but it expects clouds to come at times as well as night to come where it shuts down when solar power feed is dead. If connected to batteries, it assumes they are solar panels in good sun and pulls everything as quick as it can out of them until drained. I did such recently with a similar inverter and it pulled ~29 amps at 26V (from 2 12V batteries wired in series) draining my 100 amp-hour batteries in 3 hours. So you need to do manual control with batteries expecting such, otherwise you can plug them into panels and forget about them where it automatically comes on when the sun is out and stops when night comes 24/7.
Question:	does your house need a special meter from the electric company? or does it just use this power from solar first
Answer:	Many meters assume any power flow thru them is you using power, so it is possible for you to be feeding them power and getting charged for it. I'd assume that to be the case unless you have reason to believe otherwise on your house meter. To get a 2-way meter from the power company requires jumping thru all the hoops of permits, inspections, etc and they may not approve of these inverters for not being "UL1741" certified or such, so many don't want to go down that road. If you are sure you're using all the power this produces, it could be run and will reduce the power bill, but many aren't sure they'll have something running 24/7 to use the power constantly like that. So that's where the inverters with a "power limiter/detector" have started coming out to be sure you'll use the power before the inverter starts producing it. Of course that leads to 0 energy produced at times when you're not using it, but many will say "Better 0 production than higher charges for giving them back power". Some may even consider getting batteries to recharge during the times when power isn't needed, yet batteries can cost a bunch and always has the dilemma of "It's best to keep the batteries full for longer life and being ready for outages, yet to always have room for storing more power requires they be partly drained, so how drained do I keep them and not be going too low constantly?" Fun to try to come up with an answer to that dilemma. Going all grid-tied with the 2-way meter lets you use the "grid" as your battery getting credit for what's produced and can use it later (without needing to buy batteries), but again needs the permits etc (showing reasons some may go each way).

User questions & answers

Question:	I am getting the entire display blinking when i put any load on the system. it blinks all zeros. i have it set for 100a, but am less than 100A
Answer:	If your display is flashing or the reading seems out... (also if the reading stays 0 you probably have the wires from the shunt the wrong way round)The problem is the length of wires from where the shunt is (if it is not right next to the battery) causes a voltage drop across the cable that influences the reading and in most causes will cause the meter to flash as I suspect this is the over-read indication. (I am using three meters to measure two banks of solar panels and a wind generator)Solution: tie the battery side of the shunt wire to both 0v points on the meter . i.e. bridge the two inner pins of the connector and take the wire only to the shunt, this then takes the voltage drop over the cable to the battery out of the equation.
Question:	does this meter count up the amp hrs used and then start subtracting them when charging begins. Giving you a running total
Answer:	I bought two meters, so one measures charge, the other discharge. (Just wire the sensor wires in reverse for the discharge)
Question:	Very happy, what's the proper way to read the "energy" section of the panel? Is it real time or an average of watts per hr
Answer:	It is neither of those. The Energy section measures how much power you have used over time, i.e., the cumulative total of watt-hours. A watt-hour is equal to one watt of power used over the course of one hour. If you have a 5-watt LED bulb and you power it for 3 hours, your Power reading would consistently read 5 W for the whole time you're powering the bulb ("real time," like a speedometer), and the Energy reading would gradually change from 0 to 15 Wh over that 3-hour period (cumulative total, like an odometer).
Question:	Can you use a toggle switch to reverse the small gauge wires so you can read either draw or charge while under load
Answer:	FYI in the solution I offered above, it requires you to install the shunt for the charge circuit on the negative cable between your charging devices (all of them) and the negative post on the battery. The shunt for the load circuit should be on the negative cable between you negative battery post and the negative cable for you load panel. The load panel should have all your loads, both DC and inverter. The drawing that baylite provides does not show any dc loads. The common connection point should be the battery terminals. I hope that is clear.

User questions & answers

Question:	Should the AC power be off when connecting the panels
Answer:	It is recommended to connect the solar panel first. Then connect the AC power cord and turn on the inverter switch. Note1 : Please refer to our description for the panel open circuit voltage Voc. Note:2: Do not connect the positive and negative poles of the panel oppositely.
Question:	The external temperature of this has reached 130 degrees. Is this safe
Answer:	The inverter has over-temperature protection. When the temperature is too high, the inverter will automatically stop working. It is recommended that you install the inverter in a cool, dry and ventilated place. If your local temperature is very high, it is recommended that you install a small fan for the inverter.
Question:	If this inverter gets more DC amperage than what it can support will it just limit its output or will it blow the breakers
Answer:	1: DC20-45V can only use 36V solar panels (Voc34-46V) 2: DC10.8-30V can only use 12V solar panels (Voc20-24V)

Answer:	1pc solar panel also can make the inverter work, but please confirm the solar panel give enough amps and voltage to the inverter, for example, DC11-28v inverter, the solar panel's VMP voltage should be within 11-28v, and amps can't too small. if you want inverter to produce more power, please use severals solar panel and hook in parallel, if your solar panel give enough 500w power to inverter(don't calculate the power as how many pieces solar panel X solar panel's rated power, need to check the real power which solar panel produce), then the inverter can produce about 430w power, thanks.
Question:	On a cloudy day if solar panels only supplying 500watts of power will grid tie inverter supply 500w to utility or only works at 1kw input
Answer:	1. if solar panel only supply 500w power to inverter, then inverter produce about 500X0.83=420w power, because inverter has own efficinecy. but be confirmed the solar panel give 500w power to inverter, not calculate by 500w solar panel, usually, solar panel has own efficiency, if solar panel is 500w, it usually produce about 300-400w power. 2. this is 1kw inverter, the normal 110v output power is about 950w, if your solar panel only produce 500w power to inverter, inverter also can work too, it is within the inverter's range. even inverter has more higher efficiency beause inverter is not fulling loading, the inverter temperature is not high, the efficiency is higher too.
Question:	If I connect 24v battery (2x 12v in series), will inverter pull 500w? (500w/24v > 20 amps) If so, how many amp hours should batteries have (minimum
Answer:	thank for your question. you are asking an DC11-28v inverter, the inverter's DC fuse is 35amps, battery bank's amps can't over 35amps, otherwise the inverter's fuse will be burned. so if you hook with battery bank (2x 12v in series), this is MPPT voltage range, the inverter can run the max output power, if your battery give 500w power to the inverter, the inverter can produce about 400-430w power, because our inverter is about 80-83% efficiency when it is hot. if your battery bank's total power is 500w, and feed our inverter, we think it can keep about 1 hour, we didn't test with battery bank exactly, because this inverter was designed for solar panel, we usually test it with solar panel. any questions, please feel free to contact us. thanks.
Question:	Would it be possible to have a 300w or maybe even 150w inverter
Answer:	we have no the inverter less than 500w, if you don't want the inverter produce so many power, you no need to hook too many pieces solar panel, then it is ok, thanks

User questions & answers

Question:	I have a generator that will create the ac voltage 1-184v ac depending on the spin & is sine wave how to gti ? double pole 100 amp breaker
Answer:	I'd not expect any grid-tied inverter to work with generators. There's a few issues with such. First, when a generator is running with no load it may be at 3600 rpm keeping a good 60 hz, but when you turn on a load (especially bigger ones like a space heater) the generator will begin to stall from the load, the slowing makes the speed governor raise the throttle and it slowly "catches up". Even though it may be brief, that cycle of speed changes drops the 60 hz to 55 or such and messes up the grid tied inverter being able to stay in sync. That would likely happen often enough that every time it starts to get into sync, it kicks out again and won't ever be really doing much. I even had a generator end up "hunting" where it would constantly rev to "catch up", then slow from overspeeding, then rev again etc until I went and slowed the throttle movement to help it find a steady speed (and that would be especially bad for the GTI). Another concern I have is being able to use all the power from the GTI constantly. I think of the GTI like a water pump that constantly is sending water uphill into a huge lake that always can take everything you send it. Even with such a pump running 24/7 for months under that condition, if you were to run it pumping constantly to your house but didn't have a shower going or such to take flow constantly you could burn up the pump in an hour. Likewise with GTI units if you don't use all the power they are trying to send (with it expecting the grid to always take it all) you may have voltage spikes and such that can be bad on the house system. So these issues show why I'd not try using any GTI units with generators and on a limited house system.
Question:	Will this work with wind power
Answer:	It may accept wind power if in the 22-50V range, but there's other things to consider. I've seen some info on setting up wind systems suggesting that if you stop using the power (for charging batteries or such), then you must send the power to something else even if it's just heating elements to waste it. That way the sudden release of the load doesn't double the speed of your windmill and allow it to "run-away" to speeds that may destroy it. Unfortunately this does not "divert" a load, rather only shuts off power use and doesn't have a way to activate other equipment. So I'd look into other equipment or details like those for the wind system you're considering before trying an inverter like this.
Question:	Will this work with the New 144 1/2 Cell panels
Answer:	As long as the output of the panel is in the "20-50V" range it should be OK. Beware that many panels labeled "12V" have actual output of ~18V at max wattage and may have "open circuit voltage-22V" or such. The same pattern is true for "24V panels" having ~36V output loaded and near 50V open circuit where this model is intended for those. Look for those details on the panel.
Question:	Does this have a limiter sensor that hooks power leads from the grid and prevents back feeding through the meter. if not are there any that do? ty
Answer:	This model doesn't, lookup "grid-tied inverter with power limiter".

• 1.The small type solar grid tie power inverter can obtain the solar energy from solar panel, and can tie to the grid through its output cables with no extra equipment. The installation is very convenient and reliable.
• 2. Solar panels can be mono silicon, polygon silicon, non-crystal film or any other material that can transform solar energy to electric energy. The power of grid tie inverter should be matched to the power of solar panels connected.
• 3. The inverter can be connected to any outlets of utility grid at house. The small grid tie inverter monitors the volume, frequency and phase of the home utility grid, then produce pure sine wave AC power that the frequency and phase are as same as the grid's.
• 4. The small grid tie inverter just puts out power when the home grid is on. When the sun shines, the PV panel will produces DC voltage, and the grid tie inverter will change the DC voltage to AC voltage and puts out power to the home grid.
• 5. When the total power of electric apparatus that are using in the house is larger than the output power of the inverters, these power from the inverters will be consumed in the house, this will slow down the power meter.

User questions & answers

Question:	Can you connect a 120v power strip to the inverter and power item connedted to the inverter, ie, power outage
Answer:	You can connect a power strip to it, but the inverter will not work during a power outage. This is a grid tie inverter which must be hooked to the grid. It has island protection which makes it turn off when it does not sense grid power.
Question:	Can I plug in this inverter into a regular 15 amp dedicated outlet regardless of how many watts are going through
Answer:	Short answer is, yes. The highest rated inverter you had listed was the 600W inverter which puts out a maximum wattage actually under 600W, but for arguments sake if the inverter actually could produce 600W @ 110V A/C that is roughly only 5.5 amps, well below the 15 amp rating of a standard outlet. Personally I amnot fond of this inverter either, perticularly because it is very inefficient unless it's operating very close to the maximum D/C input voltage.
Question:	If i plug this in beforei hook up solar panel will the green light come on?will the green light come on
Answer:	never tried that as i hooked up solar panels before i turned on when solar available red leds go up higher means more power going to inverter
Question:	I now have one unit installed of this .....I would like to install another unit.....how do I connect to the existing unit
Answer:	You don't connect to the existing unit. You do it exactly the same, but separately. Or in "parallel".

• Important note: on grid tie inverter, it MUST PLUG INTO YOUR HOME GRID, it CAN'T power your device directly. for 12v solar system, the best working voltage(MPPT) is about 18-24v. sometime buyer said it can't work when it is 13v, the buyer should use it as an off grid. it is wrong using way.

User questions & answers

Question:	Would there be any harm in connecting eight 130 watt panels for a total of 1040 total potential watts or would this damage the inverter
Answer:	thank for all your reply. your suggestion are very good. but for this inverter is 500w, it iss the max AC output is 500w, not DC input. and the inverter has own efficiency too, for example, DC11-28v is 80-83%, DC22-56v is 85-90%. so they can accept different DC input. 500/0.8=625w, 500/0.85=588w. but as your panel's quantity and watts, you may need a 1KW grid tie inverter. it can accept 1000/0.8=1250w DC input（for DC11-28v inverter), you only has 1040w panels, no problem for the inverter. and just for a reminder, please ensure the DC input voltage is within our inverter's DC range, otherwise it can't work properly.
Question:	Could i this to run 2 of these panel....maximum power pmax 274$ / voc = 33.7 / vmpp =27.4 ? (i guess need to put in parallel
Answer:	it seems that your panel is not 12v or 24v system. but it can suit for our DC22-56v inverter too. you can use the panel in series or in parallel, but we suggest you hook them in series. because if it is in series, the voltage is 27.4+27.4=54.8v, it is within our DC range, and when the DC input voltage is high, the input amps is less, the inverter's temperature is low, it has more higher efficiency. if you use in parallel, it can work too, but the voltage is not MPPT range, and it is low voltage working status, the inverter has less effieciency.also, you can use DC11-28v inverter, in parallel. it is within the dc range too.
Question:	Do these provide energy to the entire house, or just the circuit to which it is feeding
Answer:	This will backfeed into the phase to which it is connected. This means that the energy output will flow from the inverter into the outlet it is plugged into, then to any loads connected to that outlet and the Associated circuit breaker. If there is any energy left it will then flow through the buss in your main breaker panel to the other circuits connected to that phase. If there's still more energy left after that then it will backfeed to your meter. Keep in mind that there will still be energy consumed by the other phase so the meter will not necessarily spin backward.
Question:	What is the minimum current input required to make this work
Answer:	It will work once it has current, there is no mini value, but the input voltage should be within the DC range, then it will work properly. if the current is small, the inverter will produce more lower power. but it has a max value, the max amps is 30a, thanks.
