Hi my name is Woody I just bought your flexible power film R15-300 my question is this solar panel a 12v 45watt . Do you sell a 18-21v 45A panel.

Hi Woody. The R15-300 produces 300mA at 15V (5W) in full sun - it will charge a 12V battery system. PowerFilm does not sell a ~18V 45A panel on Amazon, but does manufacture a wide variety of panels in various sizes, voltages & power configurations at its plant in Ames, Iowa.

Contact manufacture of your panels on what the output of both panels would be relative to your Volt/Amp requirements. It has been many years since I used Ohm's law! Good luck! (my connectors are still in the bag, as I had the same question,I received no response when I made my inquiry)

OK, this is how I think of it. Watts=amps x volts. So from their description, 7 watts = amps x 12 volts. This makes 7 / 12 = amps putting it at .58 amps. I checked the back of the panel. It says 467 mA. Google says 467 milliamperes = 0.467 amperes. Kinda close? Hope this helps.

145watts *2 panels is 290watts --- 290watts / 12volts = 24.16amps under max sunlight and optimal conditions. Youll need to use 2 charge controllers or one that can handle 48.34amp. 2 charge controllers will work together to get the batteries charged. I currently am useing 3 with my 840watts and get about 70amps to charge 9 115amp/hr batteries.

No power adapter for this unit that I know of (and we work with these a bit). However, if you can't re-angle the panel to get more sun with the changing position, then it's likely that the relatively cheap battery they use is bad.

Per the box, Solar charging voltage = 3.6V, Solar charging current= 0.4A, so by my math, 3.6 x 0.4 = 1.44W. However you don't charge directly from the solar panel with the PowerFilm - rather the solar panel charges 2 rechargeable AA and you charge your USB device from the AA. Since the USB charging voltage is 5.0V, and the USB charging current is up to 1.0A, I get 5 x 1 = 5W max for the USB output

This is the second panel I have purchased for an RV that sits fir several months at a time. I have not had any luck with either a 15w or this 30w. I suspect it is because I have a power leak in the system that drains the battery. If you buy this panel you should also install a switch that isolates the battery when not in use. That is what I plan to do this winter. I think it will work then.

i used 12 gauge from the solar panels to the controller and from the controller to the batteries i used no 6 awg i already had here The no 6 is probably overkill i wouldnt go any less than 8 from the controller to the batteries what is your battery bank at least 24v i hope

Hey Edwars O. Not sure. What type/sort of system are you putting together? 6V 12V? What are you needing to run, and for how long? What are your energy needs? I can't answer your question my friend without more info. I personally use the 400 watt system with another 100 watt panel. I match my batt bank so every 100 watt of solar for 100Ah of storage. Yes, it is over kill for just myself! I'm still in the learning processes if you will. The panels that come with this kit have zero issues with charging the batteries on cloudy days. I'm very happy with this basic system so far!!

Yes, I sent it back. Their equipment is not in conformance with any code. The inside parts are not up to any market or security specifications. I was chocked about the lack of security. It's a fire hazard ! I have 9x 150 W solar panels. Even at full performance of the solar panels ( Theoretical 1350 W) I never reached a power output of more than 450 Watt!!! I sent it back and got refunded after they offered me to send individuals parts, worth $4.50 and to soother it myself. I repeat my claim several times before I got reimbursed !

you have to look controler . to see if it can handle 46volts . as most 24 v system . handle 32v . are you sure you not have series them ? is this unloaded voltage ? even that seems high as mosr are 42 v . most charge controler have a 28 .2 voltage full charge cut off . it in equzation mode 32v . this why most panels are over rated . in watts , good rule is take away 1/4 . so a 1000 watts realy put out 750 . a mppt control helps by 30% .

Frank, i have a Renogy catalog on front of me and don't see a 350 panel. This must be something new. And by 30amp charge controller I assume a PWM charge controller. Your panel can be 12 or 24v not both, unless this is something really new. You might try one of the solar forums or email Renogy support. Don't call tech support because i tried. Don't. Ok? Try Northern Arizona wind&sun or midnite solar forums. Also midnite solar has videos on youtube about everything. You should be able to charge a 12v battery with a 12v panel and charge controller-period. Unless the battery is no good. Put a voltmeter at the output of panel then the output of charge controller. Good luck.

Yes, I use that size panel too, inverter works good. Any panel voltage should not exceed 60 volts, watts should be well under 600 watts, so no more than 2 of those panels

I have the same setup with 45 watts of solar panels. I'm using 12 gauge wire, although 10 gauge will fit. No problems with 12 gauge here.

If the input states DC 15V-24V/2A that is alot (15V x 2A = 30W to 24V x 2A = 48W) which is too high for this panel, but the 40W (18V 2.2A) Poweradd ($ 200.00) or BixPower/BixNet ($ 190.00) solar panels (or any other fixed or portable solar panel where the Watt output are 40W or above) should be able to charge that battery pack in ideal sunny conditions.

I have five 100 watt panels now, wired together with MC4 split connectors and running 25 feet to my charge controller. My panels have a working voltage of 18.5V. That gives me 5.5 amp per panel in direct sun. In total I get 27 - 28 amps on a clear day. I have no problem with voltage drop but I am now max'd out on my 30 amp charge controller and the 10 guage wire. If you have a larger system than that you will need heavier wire, unless your panels operate at a higher voltage, wich would lower your amps. As long as you are under 30 amp this wire works great. I hope this helps. Dan

Check those specs again... where did you get 15amp from?115v x 15amp = 1725watts.A 50w panel will not power a 1725watt appliance.Your best bet is to buy a Kill-a-Watt meter from amazon.That will provide you with accurate usage specs.
