This customer wanted a robust system that was easily upgradable.
A large 3000 watt inverter wired directly into a 120/220 volt sensing switch allowed for a fully integrated, shore power simulation style install. 3 x 100ah lithium batteries serve as energy storage, with room already set aside for expanding with a 4th. On the roof 1000 watts of solar was ran into a combiner box and wired to an oversized solar controller to make adding an additional 400 watts in the future a breeze.
1000w Solar, easily expandable to 1400w
300ah Lithium with room for expansion
Fully Integrated Simulated Shore Power with 120/220V auto selecting switch
