I plan to use (2) Unisolar 136-watt flexible panels with this (also sold on Amazon), will this controller work at max output?

Yes, your two panels should have less than 20 amps output, under the best conditions. They should put out about 7.5 amps each, equaling 15, well within the 20 handled by the controller...

a morningstar 60 <AMP> controller will not be big enough, this is what I have for just 3 of the panels, and it is maxed out. Have you looked to see if you can put 5 on top ? I have a 35 foot RV but there are a lot of things up top that get in the way... Anyway, get the 80 amp morningstar and maybe just 4 panels.The grapesolar and the morningstar have worked very well for me. I would also suggest the remote panel(s)good luck !

Yes if you have solar panels that put out as much as 32 amps controller. 12v x 32a =390 watt. This is a pretty big system.

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.

I'm not sure (amp wise). But I have 1000 watt panels connected to my charge controller for about 6 months now, and it's working excellent.

This may or may not work,I recommend a larger panel as this panel only puts out about 0.7 to 0.85 amps under typical conditions.

A 30A Charge controller WILL be adequate and will work but it is a narrow margin for your 145 watt panels. I estimated the amperage on your panels @ 7.25 amps each, that put you right at 29 amps. Barring any solar fluxes that might tip the controller to temp shut down you should be ok.

There are too many variables to give a definite answer. ie. Are you using an individual controller for each panel or one controller for all three? Have you considered back flow from one panel to another? How about voltage or amperage input to the controller(s)? Also, the 128 watts is an ideal, under perfect conditions result. Do not expect to produce this much power. They are good, useful panels, but I don't know of any panels which produce their rated power consistently.

It's rated at 20amp. Each of these panels are rated at 5.7amps. It should handle 2 panels, perhaps 3. I would think 4 panels would begin to limit the amperage. You can also use multiple charge controllers rather than trying to attach a larger array of panels to a single controller.

I'm using this controller to charge a bank of 4 12 volt batteries and my solar panel is rated at 30 watts and 17.5 volts. It seems to be working fine but I don't know if the controller lists any maximum input voltage or not. One would think it would be capable of handling a wide range of voltage just because of the nature of most solar panels but that is simple logic and simple logic doesn't always apply.

Yes, as long as you do not exceed the voltage and current limits of the controller. For instance, if you are connecting two 5 watt panels in series, the voltage will be double that of a single panel but the current would be the same as a single panel. Conversely, if you're connecting the panels in parallel, you'll have double the current but the same voltage. In that case you'd want to ensure the controller is rated for the increased current.

Yes, but the unit will only control 11watts worth of LED strips. Also you have to figure that load on your supply. Doing the math you can drive around 9A with this controller. But that is at almost 100% of it rating and that is not advised. I would only run it at 50-60% of it rating. So 5-6A Now you just need to find out how many Amps or watts each string draws.

Yes this controller will work for you. You will need to use it to control a relay for that large of a load. I used a 60 amp definite purpose relay to control (4) 3.6 KW heating elements.

Hello,For x4 of the 250 watt panels would be too much power for the controller to support in 12v let alone in 24vThe minimum you should go to run these on 12v would be roughly 96 amp controller such as the MidNite Classic.Please let us know if you have any other questions.Regards,Austin WaltiRenogy Technical Support Rep.

If you plan to add more panels, you will need to use a bigger charge controller or stack another charge contorller. This charge controller only only fit 240W and 480W for 12volts and 24volts system.

That will work just fine. Just make sure your solar controller is rated for at least 10 amps and preferably 15 amps just to be safe.
