SunGoldPower SGM-5K5E review
SunGoldPower 5000W 48V Off-Grid Solar Kit, 5.12kWh, 6 x 200W Panels (SGM-5K5E)
By Tom Calder
A 5,000-watt, 48-volt inverter with Wi-Fi monitoring, one 5.12 kWh lithium battery and six 200-watt panels. The bigger inverter handles more at once than the 3,000-watt kit, and a 48-volt system is easier to grow with more batteries later. Output is 120 volts only.
