18+ volts is the Vmp (not Voc) of a 12 volt panel. --vtMaps1 · -
Re: Newbie question regarding solar system
I just looked at the specs on that inverter... OMG! it draws 200 watts on idle! The highest you can set the low battery cut off is 42 volts... this thing sounds like a battery killer. And it can surg…1 · -
Re: Newbie question regarding solar system
Yes. You would need a Classic 200. I should have mentioned that. If you can find a couple of 12 volt panels with an Imp very close to 8.78, you could put one of them in each of your strings and use …1 · -
Re: Newbie question regarding solar system
If you upgrade to a Midnite Classic you should reconfigure your panels to a higher string voltage. Most controllers require some headroom, in other words the string voltage needs to be higher than th…1 · -
Re: Battery issues
Your optimal configuration will be a string length of two (Vmp of string = 62 volts). After you add the last two panels (8 total), you will need a 4 position combiner box. --vtMaps1 ·
