The Sungoldpower SGR-8K10E is a complete off-grid solar kit built around an 8,000W 48V inverter, eight 450W N-type panels and two 51.2V 100Ah LiFePO4 server-rack batteries (10.24kWh). The inverter delivers 120V/240V split-phase output, takes up to 11,000W of PV through dual MPPT, and can be paralleled with up to six units for 48,000W. The batteries are UL1973 and UL9540A certified, rated for 7,000+ deep cycles, and expandable up to 63 units in parallel. It suits off-grid homes, cabins and backup builds that want a matched inverter-and-battery package rather than piecing parts together.

The SGR-8K10E is a complete off-grid solar kit. It combines eight 450W solar panels, an 8,000W 48V off-grid inverter and 10.24kWh of LiFePO4 battery storage. Under 4 hours of full sunlight, it generates approximately 14.4kWh of solar energy per day. It can power homes, cabins, RVs, vans and backup systems.
The inverter delivers 8,000W of 120V/240V single-phase/split-phase output. Its dual MPPT inputs support up to 11,000W of solar PV input, and up to 180A of combined solar and AC charging. Wi-Fi monitoring is included. Up to six inverters can be connected in parallel for up to 48,000W of output.
Storage comes from two 51.2V 100Ah server rack LiFePO4 batteries with automotive-grade cells. They are rated for 7,000+ deep cycles and up to a 15-year lifespan. The inverter and batteries support RS485 communication for system integration and battery management. You can add compatible batteries and solar panels as your needs grow.
