The 5 x 200W solar panels were roof mounted. Each panel was wired to a combiner junction box in parallel for best performance in shade. Large 2AWG wire was used to transition from the combiner box to the solar charge controller installed local to the batteries.
The solar charge controller was mounted local to the batteries on a panel that provides protection for the wiring connections when the compartment is used.
The SmartSolar charge controller is also Bluetooth enabled so that daily performance can be monitored.
