Currently there is a 6.48 kW roof mounted solar system with a reverse tilt facing south using a Silfab 360 watt panel. The Sol-Ark 12 kW is here used with Tigo optimizers and 19.6 kWh of LiFePO4 batteries from Sacred Sun. These batteries carry a 10 year and 6,000 cycle warranty. This system is also integrated with a manual roll out gas generator. The inverter is oversized as the customer plans to add more solar.
