SunGold Power 6.5kW Off-Grid Solar Kit vs SunGold Power 5kW Off-Grid Solar Kit

Buy the 6.5kW kit if you need 240V: a well pump, a shop with 240V tools, or a small off-grid home. Buy the 5kW kit if everything you run is 120V and you want more stored energy and more solar in the box. The 6.5kW wins on output, split-phase capability and expandability, with a 6,500W inverter, 13,000VA surge and room for up to 10,000W of PV. The 5kW wins on battery and panel capacity at the same 10.24kWh bank, with 2,700W of bifacial panels against 2,220W and Wi-Fi monitoring. Owners of both praise the build and the included cables; the main complaint on the 6.5kW was a short shipment that took repeated calls to resolve.

• Choose the SunGold Power 6.5kW kit if you need 120/240V split-phase output for a well pump, 240V tools or a small off-grid home.
• Choose the SunGold Power 5kW kit if every load is 120V and you want the larger battery and more solar panels in one box.
