SunGoldPower SGM-8K20 review
SunGoldPower 8000W 48V Off-Grid Solar Kit, 20.48kWh, 12 x 450W Panels (SGM-8K20)
By Tom Calder
An 8,000-watt split-phase inverter, 5,400 watts of panels and 20.48 kWh of lithium battery in one kit, twice the battery of the SGK-8MAX. SunGoldPower says up to six inverters can run in parallel. It is a DIY kit meant for large installs: wiring it into a home calls for a licensed electrician, NEC compliance and local permits and inspection, and the maker's manual covers DC breakers and cabling.
- Best for
- A large cabin, shop or homestead that needs 120/240V and a big battery
- Skip it if
- You don't have the space for twelve panels or can't have a licensed electrician do the wiring
