User questions & answers

Question:	Will this charge two deep cycle battles at the same time
Answer:	I don't know where the 2 other comments came up with one amp output. Minimum is 5.1 amps with mttp controller. Still insufficient to fully charge deep cycle flooded battery with much load.
Question:	Are there any directions with this item? also, do i peel off the plastic coating? it is all bubbly like i should, but i am not sure
Answer:	No, there are not really any directions but it’s pretty simple to use. Yes, peel off the protective plastic layer. I know it looks like it is attached underneath the fabric but it comes pretty easily.
Question:	how long will it take with good sunlight to recharge a dead 12v automotive battery
Answer:	The right answer is: It won't. 5W is the absolute best these cheap panels will output, in reality you will only get about 1W during daylight hours, mostly due to thermal derating. The charge will be so minimal, that battery leakage at night will eliminate any small charge you get during the day.
Question:	Does this have a blocking diode
Answer:	I don't believe this panel has a blocking diode built in as CX wrote in 2018. Can seller confirm whether there is a blocking diode built into the panel? Thanks

Answer:	this kit will work way beyond that as long as you have enough batteries to hook it up to.it can charge your van battery and run 12 volt appliances through your cigarette lighter or run 120 volt appliances with an inverter that can handle the amount of watts you want to use.be careful of sensitive electronics while using a cheap inverter.you may need a sine wave inverter.i would highly recommend a good group of deep cycle batteries.the more batteries the more you can run.check out youtube for lots of answers.hope I was able to help
Question:	How many amps are charging the battery while inuse, on a sunny day
Answer:	I purchased this system to act as a 'test bed' prior to buying my main dual-axis 2 panel system (Two 250W, 24V 8A panels). It's a monocrystilline 100w panel stated to output 5 amps, 12volts. I see consistent 13~14 volts at 4 amps, and have hit 5 amps on really good days (but 4A are more realistic). As a test item, I had it charging a 73AH Deep Cycle Gel battery from West Marine (the panel came with a 30A PWM charge controller). It worked fine and charged the battery in a matter of short hours ( I have both an amp meter and a volt meter connected to track its output). Previously, I was using two 45W amorphous panels (Harbor Freight) that took up to 4 days to do what this one panel can do in 4 hours. Buy with confidence.

User questions & answers

Question:	My house battery is too hard to get to for alligator clips. What would I need to hard wire this system to my battery
Answer:	I got this extension cable: https://www.amazon.com/Go-Power-GP-PSK-X30-Expansion-Accessory/dp/B00FYV4DU8 And I got this accessory: https://www.amazon.com/Go-Power-Trailer-Accessory-Portable/dp/B00FYUCQXK, to which I added the appropriate quick-connector. The 30’ cable coils up inside the back of one panel when folded, I keep the 7-way hookup accessory in a little bag with other accessories. I simply set up the panel somewhere within 30’ of the front of my trailer and plug it into the 7-way coming from the trailer. Works like a dream to keep my LiFePO4 battery charged up, even on less than perfectly sunny days! No need to alligator-clip it to battery under the couch in my trailer. I did get a charge controller from Zamp Solar, because Renogy’s did not support lithium batteries at the time.
Question:	Can i add more pannesls
Answer:	I assume you are asking if the included charge controller can manage additional panels? If you are looking to add panels in parallel (maintaining the nominal 12V output while increasing amperage), my answer would be, "not recommended." This controller is rated at 10 amps. At full 100 watt output, it is operating at around 7 amps, so there's not much additional capacity. If you plan to add panels, I would suggest ordering the kit without the controller, then add a higher capacity controller such as this 30 amp model...http://www.amazon.com/RENOGY%C2%AE-ViewStar-Negative-grounded-Controller/dp/B00LG0DAQO/ref=sr_1_2?s=lawn-garden&ie=UTF8&qid=1428654662&sr=1-2&keywords=viewstar It will require some know-how and additional wiring to properly set up.
Question:	Anybody know how long you can run the batter/power cable...? I'm thinking from the top of an RV to the ground +/- 12-15'. Thank you in advance
Answer:	With 10AWG wire between your controller and battery, 30' of wire will give you 3% drop. Only 15' of wire could be used if you add a panel and have 200W of PV power. That's not the best practice though. Best would be to use an MPPT controller connected as close to the battery as possible. You would then be able to use 55' of 10 guage wire between the controller and panel, or 110' if you double your voltage by adding another 100 watt panel in series.
Question:	What is a good extension cord to buy with this for more mobility from my RV
Answer:	There is a lot of wrong and misleading info you're getting here... It primarily depends on your controller. If you have a garbage (PWM) controller, then 25' of 10AWG wire is your max. That puts you at 3% voltage drop. If you have an MPPT controller, you can go 55' with 10AWG wire. Now, here's the kicker, and the reason nobody should be buying these crappy PWM controllers; If you add another 100W panel in series to your MPPT controller, you can now use 110 feet of wire, and your voltage drop will still be 3% because you're doubling your voltage. If you add a panel to a PWM controller, you'll have to cut your wire length in half. DO NOT BUY PWM controllers!!!

User questions & answers

Question:	Why does this say "12v-18v" in the title but only "12v" in the description? Does this provide 18v
Answer:	I am not sure about that model but there are 6/7 connector tips and I would think one of them would work.
Question:	Would this charge a goal zero 400 W solar battery
Answer:	No, it's not made of glass. It looks durable like plastic (it's definitely more high-tech than plastic).
Question:	How do i connect 3 panels in series? What parts do i need to connect
Answer:	it is 5.5x2.1cm
Question:	Will these work in a 48v system? 4 in series would be over 15A
Answer:	Zamp and other pre-wired adapters to smaller RV's tend to try to convince you that theirs is the only one and preprietory plugs etc. However you can search for Adapter plugs that will allow you to use just about any solar charger similar to this folding panel including the larger suitcase style panel systems to with the Zamp or similar plugs. Most buyers of these however will not have your specific answer unless they by chance have an RV that has the pre-loaded Zamp brand. Sellers of these often skip question slike yours too. And to be more specific NO this one does not have a specific Zamp plug to fit your outlet on your trailer. HOWEVER search for adapters that will pair your Zamp specific to this or similar solar panel chargers. Stay safe and happy camping and fun time. Amazon Search for example:2 Pin Power Industrial Circular Connector to Solar Panel Cable Adapter. And that works with an M4 plug so make sure you can adapt those or rewire with proper plugs to your solar panel such as this or other styles. I have two roll up portables such as this one that are not MC4's but my home made 100 watt using Renology flexible panels for light weight and super effective chargers were MC4's that needed rewired to parrallel for a goal Zero 1400 lithium so to Anderson plugs which have to be configured right to fit a Goal Zero's port. But some of these portable panels actually come wired with or have adapters for the MC4 plugs already. Always check your polarity and requirements. Also if you are lithium or deep cell. And finally watch some Youtube videos on how to there is a lot of info to be gained from DIY folk. (PS as a female just at 70 this year I made my own wonderful ahead of technology folding semi flexible folding 100W solar portable panels that are light weight. When I went from deep cell 800 watt batteries that accepted solar charging to the Goal zero I had to rewire that and didn't expect it to work well after the adaption but oh my gosh it works great. Since Goal zero accepted over 200 watts of power all at once I contacted them to make sure it was safe to use two different sources one this portable via the 8mm charger port and the anderson ports via my homemade still my favorite solar panel for light weight and adaption and how great it charges. I was given the green light so if a 65 to 70 yr old can figure it all out so can YOU.
