The max wattage 390w 12v / 780 24v, Is that panel voltage or battery voltage? Can I hook up 780 watts of 24v panels up to a 12v battery bank?
453601
The batteries are ether 12 v or 24 v. The tracker automatically goes to the battery voltage. You will notice that the output of the tracker is twice as many watts on 24 v as 12 v. A 24 v system will work twice that of a 12 v system. The batteries must be wired for 24 v,the inverter must be 24 v and the backup charger must be 24 v. The panels must be wired in series to make more than 24 v. A system that works poorly on 12 v will work great on 24 v.
453602
The answer to the second question (780 watts @ 24 volts into a 12 volt battery bank) is yes. That's what I do (600 watts 24 volt into a 12 volt battery bank.)
453603
Since the Controller os automatic Voltage sensing on the Battery Side, the answer is NO. The Controller will sense a 12v battery system and will shut down, as in overloaded. The Controller will allow you to hook up to a 24 volt solar panel but the max input into a 12v battery system is 390 watts (30 amps nominal throughput to the batteries).

No. It's battery voltage. Think about it this way: The device is current limited because current is where the heat is coming from. If you have 12V batteries, you get 390W max power, but with 24V batteries, you get twice the power at the same current limit.

Yes- I have connected a 240w panel (30V @ 8amps) and also two 135w panels (total 35V @ 3.8amps each) and it works fine. The limiting factor that may cause the confusion is that the maximum output is 240watts (12V @ 20amps) if you are connected to 12V batteries. In my case, I was connected to a 24V battery bank and was dumping about 17amps at 26volts into the batteries when I had all panels connected (the 240W + 2x130w). For the money the controller works well. If you connect to 12V battery; 240w is maximum; if you connect to 24v battery you can get 480w. It doesn't support over 32 volts, so you can't use a 48V battery bank. Yes- I have connected a 240w panel (30V @ 8amps) and also two 135w panels (total 35V @ 3.8amps each) and it works fine.

This is why I hooked my 520 watts of panels in series so you halve the amperage. I can add another 2 panels in the future and still keep it under 30 amps. Remember too that the charge controller can charge a normal 12v battery bank, that's what mine is. I recommend making a 24v panel setup.

I can confirm Renogy Solars answer (it'll work with either 12V or 24V battery banks). I use this panel with a MPPT controller and a 12V battery bank.

It is rated for 10 amps input and output. If it can handle 48 volts (which I don't know because I have a 24 volt panel) it will receive 48 x 10 or 480 watts (volts x amps equals watts). However, if you are charging 12 volt batteries it will only put through 120 watts. I ended up trading this in for a 20 amp controller because of this. I am very happy with the 20 amp controller.

There are different ratings for the battery pack and each voltage output on the panel. The battery pack is rated at: USB port (output): 5V, up to 1A (5W max), regulated USB-mini port (input): 5V, up to 0.8A (4W max), regulated The panel itself is rated at: USB Port: 5V, up to 1A (5W max), regulated Solar Port (blue, 8mm): 15V, up to 0.3A (5W max), regulated Mini Solar Port (2.5mm): 6.5V, up to 1.1A (7W max) Keep in mind that the panel output figures are MAX in optimal conditions and the vast majority of the time the output will be considerably less than this. It will also vary quite a but from minute to minute with light intensity, light angle, clouds passing by etc. So for any USB devices I'd plug the battery pack into the panel and the USB device into the battery pack. It will result in much more consistent, and faster charging most of the time. For 12V applications this panel doesn't have much output (300ma) for directly running devices, but its ok to very slowly trickle charge 12V batteries.

One 85 watt panel Should deliver around 7 amps at 12 volts in full sun. If you have all 4 panels connected through a single (7 amp) controller, it is way overloaded. Sounds like you might need 3 more controllers or simply a bigger controller unit.

I see its states 12/24 volts.,100volts, woow that's a lot.,,yes Pv power refers to the solar panels as far as I understand.,i have a 12volt system.,with one 100Watt panel.,you have 24volts, so what are you confused about. you have another 76 volts to go before you could have problems.,,,LOL...Hope this helps.,we are all learning.,,

Frank, i have a Renogy catalog on front of me and don't see a 350 panel. This must be something new. And by 30ampcharge controller I assume a PWM charge controller. Your panel can be 12 or 24v not both, unless this is somethingreally 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. Frank, i have a Renogy catalog on front of me and don't see a 350 panel. This must be something new. And by 30ampcharge controller I assume a PWM charge controller.

As long as you are producing 24 volt DC and storing it in a battery bank, you will be able to draw power from the battery bank and produce the 120 VAC house current. Not for a direct hookup from the solar cells to this or any other inverter.

Battery in question is 100ah x12v = 1200 watt hours. This panel can provide 144 watts per hour for battery charging purpose. Rule of thumb batteries should not be drained more then 50% or maximum 80% otherwise battery life will be compromised, so we will consider 600 watts to be charged. 600 watts divide by 144 watts = 4.16 hours. Since this panel is 24 volt and your battery is 12v - MPPT charge controller is highly recommended. MPPT charge controller can accept higher voltage (24~36 volt) from the solar panel and charges a lower voltage battery (such as 12v). Morningstar SS-MPPT-15L will be a good charge controller for this setup. Battery in question is 100ah x12v = 1200 watt hours. This panel can provide 144 watts per hour for battery charging purpose.

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!!

Hello,If you are charging 24v the controller can support 3 of these panels.In 24v the controller can support up to 800 watts.Please let us know if you have any further questions.Regards,Austin WaltiRenogy Technical Support Rep.

Do not hook up to 24 volts, it's For 12v to 13.5 dc volt . You can find good one inverter 24 volt @http://www.theinverterstore.com/2500-watt-power-inverter-24-volt.html

The number of amps per panel depends on the the amount of light on the panel. At the rated maximum 130 Watts, (Watts = Volts X Amps) so, about 10.83 Amps per panel maximum at 12 volts. Don't expect the maximum, that is in nearly perfect conditions and location. I routinely get about 15 Amps to the battery at noon in the summer in Northern California.

The panel is rated for a nominal rating of 24V. It can deliver to a 12V or 24V battery bank based on the charge controller that is used. If you are using a 12V battery bank you will want to use a MPPT controller.
