MPP question

[Nedlyest]

Hey guys,
I'm starting to Wade into the pool. The 48v MPP listed on the all in ones page, the 48v refers to your battery voltage? Not the solar array input? I see in specifications it can have an input up to 110vdc, does the battery bank need to match input or does the controller convert to the 48v?

Yes, 48VDC refers to the nominal battery voltage. 4 x 12v in series, 2 x 24v in series etc. The PV input voltage does not have to match the battery voltage, but for the unit to charge from solar it has to be higher than the battery voltage.

Awesome thanks for the info ?.
