SunGold Power 20kW 48V Off Grid Solar Kit – 30.72kWh LiFePO4 Battery + 32 × 440W Panels (SGR-20K30E/SGR-20K30T)

The SunGold Power SGR-20K30 Series delivers true whole-home off-grid capability. This system includes 2 × 10kW 48V split-phase inverters (20kW total), 32 × 440W high-efficiency monocrystalline panels (14.08kW array), and 30.72kWh of LiFePO4 batteries (rack or self-heating options available). With ~4 peak sun hours, this kit can generate ~56kWh/day, enough to run large homes, cabins, or commercial setups with high-demand appliances such as air conditioners, well pumps, refrigerators, and shop equipment.

Scalable design allows you to parallel up to 6 inverters for expanded capacity, while rugged solar panels and long-life LiFePO4 batteries provide durability and peace of mind. Perfect for homeowners, off-grid enthusiasts, and remote applications needing reliable and independent power.

FAQs

Q: Can I use both 120V and 240V at the same time?
Yes, but note that 120V loads are limited to 50% of inverter output (≈6kW per inverter).

Q: Will this system work with 3-phase?
Not directly. It supports single-phase 120V, split-phase 240V, and 208V three-phase when paralleled with 3+ inverters.

Q: How much power does the inverter use with no load?
Idle draw is 40W (power saver on) or 180W (power saver off).
