I'm planning to install two 130-watt
Kyocera panels to help charge my house bank of four
AGM batteries.
The controller recommended by the retailer is a
MPPT 250 by BZ Products. Anyone have experience with this controller?
Also, I read on another forum that
MPPT controllers should only be used with large
solar array systems because the controller takes more energy to run than the additional output they provide. Can that be right? Would I be better off with a non-MPPT controller?
Thanks.
