Originally posted by Nazproperties View PostWith my CC set at 12 volt and the 2 6 volt batteries wire in series for 12 volts would the connections be + on one battery and - on the 2 battery?
Then connect your charge controller to the + of 1 and - of 2. You would connect your inverter to the same terminals.Comment

Power and current add in parallel. Parallel is less efficiency and cost more
Power and voltage add in series. Series is more efficient and cost less.MSEE, PEComment

Originally posted by Mike90250 View PostThe other half, is the charge controller. under 400w, it's cheaper to use the PWM style (70% efficient). Over 400W, MPPT is the suggested (95%) And if you go series, you will need MPPT to downconvert the 60V from the 4 PV's to 15v for battery charging.MSEE, PEComment

watts
Originally posted by Sunking View PostI think you meant 200 watts right? I can build a 200 watt MPPT system for less than an equivalent 300 watt PWM system.Comment
