User questions & answers

Question:	Is there a way to adjust the float voltage on this unit
Answer:	No, the float voltage on mine is 13.8V no matter the battery type setting. There is a manual on the Renogy website that lists float at 13.2V when set for Flooded batteries. However that is not the case on my unit, which I bought in 2016.
Question:	Can anyone explain the middle led's lighting sequence? What are the possible states of display, blinking, on, what do they mean
Answer:	The middle LED's lighting sequence is as follows: Green ON when battery level is in the right range. Green slowly flashing when battery level is full. Yellow ON when battery level is low. Red ON when loads cut off. Hope this helps.
Question:	max number of 100w panels for this controller
Answer:	This will depend on 2 things: 1 - what is the amp rating of your controller. &. 2 - what is the nominal voltage output of the panels. A 30 amp controller can handle a maximum of 3.6 100 watt panels of 12 volts (100 watts / 12 volts = 8.33 amps, 30 amp controller / 8.33 amp panel = 3.6 panels per controller). Of course, you can't have .6 panels so the safest load would be 3 panels. Yes, math is VERY IMPORTANT when being safe with electronics.
Question:	The description says "These are Positive Ground Controllers." How do you ground a system on the positive side
Answer:	Please ignore this if you're not interested in a dissertation on grounding. First, THIS is a NEGATIVE "ground" controller, so that's GOOD. Why? "Ground" is a misleading term. I've designed stuff for NASA spacecraft that had connections called "ground". Whaaat? We're going to run an extension cord to the spacecraft, so we can keep it tied to a metal pipe stuck in the dirt? Nope. "Ground" is just what electronics folks usually call a COMMON POINT the circuitry is referenced to. It doesn't necessarily have anything to do with the ground we walk on. Electrical stuff works by having two sides, positive and negative, with a voltage difference between them, the "pressure" that makes current flow. Electrical power folks tie one side to the dirt your house sits on, for safety. Your house has water pipes and stuff that's pretty well connected to the dirt. If you grab a water pipe and the 110V ground at the same time there's no voltage difference, so current doesn't flow through you and hurt you. 110V is 10x higher than a solar panel voltage so it's a lot more dangerous. Tying one side to the dirt was a very good idea. Long, long ago, and far, far away, electrical power folks chose the negative side to connect to the dirt, and most stuff made since has pretty much matched that. Then some folks decided to make "positive ground" devices, because for their designs it was easier and cheaper. Some of us think they should have been spanked. It caused all this "positive ground" and "negative ground" malarkey. On to solar power systems. Think of it like this: A controller has electronically controlled switches in it. One switch connects the solar panel to the battery to charge it and disconnects when the battery is full. Another switch connects the load to the battery when you want the load turned on. In a "negative ground" system, the terminals of the panel, battery and load called "minus" or "negative" are all tied together, and the controller switches the positive side connections. Since many loads are connected together on the minus side to ground (dirt) this is a GOOD THING. In a "positive ground" system it's the opposite. The positive side of everything is tied together, and the controller switches the negative side connections. Imagine this: If you connect the battery negative terminal and the load negative terminal both to ground (shorted together) and the controller switch is between them, what happens when the switch opens? That's right, NOTHING. The switch is shorted out by your ground connections so it can't disconnect the load. So that's what's wrong with a positive ground controller. Everyone is used to tying negative together and to ground and they do that and it screws up the controller. But a positive ground controller can be used as long as you don't connect the battery and panel to *anything* except the controller. For example, your van's battery negative is connected to the chassis of your van, and so are the negative sides of all the lights and devices in your van. JUST DON'T TIE THE SOLAR PANEL OR SOLAR BATTERY NEGATIVES TO YOUR VAN CHASSIS TOO. You CAN tie the controller's load output negative to your van chassis, as long as you don't connect any. other. point. in the solar charging system to chassis too. With a "negative ground" controller you don't have to worry about any of this malarkey. You can tie the battery, panel, load negatives all to chassis without any problems. This is why NEGATIVE GROUND CONTROLLERS ARE BETTER. Sorry for the lengthy explanation. I hope folks can follow this and it helps them understand this "ground" stuff.

User questions & answers

Question:	Can I hook up a 750 watt inverter to the Load terminals of the controller
Answer:	No you cannot. As previously stated, I’d hook the inverter straight to battery although you can hook a relay in series between the battery and inverter and use the controller load to power the coil of the relay. This will allow the controller to shut down the inverter in case of any problems. Use a relay rated for at least 70Amps for a 750 watt inverter.
Question:	Can you set this to charge the battery once it gets to a certain level
Answer:	It will charge the battery and taper off when the battery is fully charged. It won't charge a dead battery or work well if the battery is in a low charge state.
Question:	Can this controllers output voltage be set to 24 vdc? i need to series two twelve volt batteries and supply a system with 24 vdc
Answer:	The information on specs are unclear but it does work. I have two 12 volts in series on my boat in flat storage with no electrical around. I bought one 24V solar panel, connected to this controller and it works great. The serttings are automatic if you follow directions. Here is my summary for my fishing club: There’s math involved to determine solar panel size so hang in there. Each battery is 12 Volts rated at 90 amp hours (AH). Multiply volts times amps to get total watts. 12V X 90ah = 1080 watts each, times 2 batteries = 2160. That’s total watts from zero to full charge. Since you can’t run batteries to zero and expect them to work, only half of the power is usable. Therefore, my needs are half of the 2160 total = 1080 watts. I decided I wanted to get fully charged batteries after 2 days. There is good sunlight on my location an average of 6+ hours per day so I need a panel large enough to reach 1080 watts in 12 hours charging time. Watts divided by hours, 1080/12 gets me my panel size of 90. Solar panels and connections are subject to voltage loss due to dust, connections, shadows, etc. Figure 20%. I need 120 watts output in a 24-volt panel (match my battery voltage). I found the components below. A 24 volt, 150-watt panel, a controller (don’t want to overcharge) and special solar wiring and connectors all on Amazon.
Question:	Ok asking my question again. .... How many working amps? Didn't know children answered these too. Lol
Answer:	I think Dana is a little confused regarding the requirement for HEAVY gauge wires at 20 amps (as in "the wire would be too big for the controller connection screws"). 20 Amps at 12 volts is only 240 watts. (Meanwhile, 20 Amps at 110 volts is 2,200 watts, which WOULD require a heavy gauge wire.) You can easily attach a wire capable of handling 240 watts to this controller. I use this controller with three panels installed on the roof of my RV. (One 50-watt panel and two 160-watt panels, connected in parallel, for a total potential of 370 watts.) The controller works great, allowing for perpetual wilderness camping without running down my RV coach batteries over multiple days - even when using a heated Bi-Pap (CPAP) machine all night long using a 120v Inverter. I've seen this controller charge the batteries with 16.8 Amps at 13.7 volts (230.16 watts) with no issues or "hot wires". Dana debunks the controller for feeding 2.6 volts at 1 amp back into the solar panels. That's a whopping 2.6 watts, which is inconsequential next to two deep-cycle coach batteries connected in parallel. Besides, that's what blocking diodes are used for.

User questions & answers

Question:	Do you sell the cable for the temperature sensor
Answer:	The temperature cable comes with the 60amp as well as the mt50, not sure about the others
Question:	If i hook this to a 95 volt 18 amp permanent magnet dc motor/dynamo, and spin it up, will it harvest power as effeciently as it does with pv panels
Answer:	Im guessing this (dynamo) is stable and it is producing dc then yea.
Question:	who do I return a defective unit for factory warranty
Answer:	The manufacturer
Question:	Hello i have 10 * 250 watt solar panels. i noticed the max input voltage is 150v. can these work with your unit. if so how should i configure
Answer:	Voltage does not add up. If the panels are 40 volts each then your voltage will be 40. Only way to have a higher voltage is if you wire panels in series. Example ( positive to negative) 2 panel's at 40 volts each in series would be 80 volts.

User questions & answers

Question:	If a conect my panels and my batteries to 24 v what will be the voltage that I¨ll recibe in the in load terminals
Answer:	Let say solar panel produce 36Vdc And battery voltage is 27Vdc The load terminal is about 27Vdc
Question:	What version of the 20amp model is being sold here from amazon? per the manufacturer website, renogy bt, is optimized for rover charge controllers f
Answer:	This is last year's model and currently sold out here the Renogy website and eBay. New models coming. Rich solar still has them at $89.00 for the 20amp..but offers no bt module
Question:	Can I disconnect the battery while the solar collector is still connected
Answer:	No, I dont think that's a good idea since they say connect batteries first the solor panels. If you was to shut ur system down, the go in reverse. Panels discount then battery.
Question:	Is anyone having problems with hf / vhf radio interference (rfi
Answer:	On MPPT and PMI controllers of different brands, RFI particularly in the VHF & UHF bands can be extreme. The solar panels do act as large antennas transmitting the interference. Some fairly simple decoupling circuitry can help. Right at the PV input, i've used a large forward diode into a large, CPU-grade electrolytic along with common-mode chokes on wiring before the diode. On the controller outputs, a "Corcom" type pi-filter helps a lot, but components in series with the output must accept full output current without much voltage drop. This can get rid of about 99% of RFI without too much problem. I do use solar and wind turbines for power at my off-grid property and run amateur radio equipment from 70 cm to 160 meter bands.

User questions & answers

Question:	Does this have battery overcharge protection? Or is it called something different
Answer:	Hello, The MPPT is designed to charge your batteries as a default voltage of 14.4V when in absorption mode (batteries are flat) then it reduces down to 13.8V when batteries are charged. These setting can be adjusted (the 24V setting are default at 28.8V and 27.6V respectively). Maximum output current is 30A. If you are worried about over charging due to different charging needs for your batteries these can be adjusted from the above settings. Hope that help.

User questions & answers

Question:	What is the default battery type setting if I choose to plug and play without messing with the blutooth app or an additional control module
Answer:	AGM. That being said, the app takes about 20 seconds to set up and use, so it's worth the time.
Question:	what's the maximum load wattage I can put on this? I know the max charge current is 20a, but is the load fused, or just pulls from battery
Answer:	To correct multiple incorrect answers on this question: The fuse is to protect the charge controller from reverse battery connection: it DOES NOT protect the load output, nor does it protect the charging circuit to the battery, nor does it protect the PV input. Please see the user manual available at victronenergy.com/support-and-downloads/manuals.
Question:	When using an a/c battery charger/converter, do i hook it's output to the load side of the controller
Answer:	You can have multiple charging inputs to the batteries. They will work just fine independent of each other. Typical motorhome has alternator, inverter/charger and solar charger connected.
Question:	The item i received says 48v on the side. will it work with 12v/24v systems
Answer:	Even though the mppt has the 48V stamp, it will work with 12V 24V & 48V systems. The 48V is to differentiate it from the 12V/24V only mppt. Here is documetation from Victron showing it will work with all three Voltages. https://www.victronenergy.com/upload/documents/Datasheet-SmartSolar-charge-controller-MPPT-75-10,-75-15,-100-15,-100-20_48V-EN.pdf
