A complete off-grid solar package built around a 6,500W 48V inverter that outputs 120/240V AC, six 370W monocrystalline panels, and a 51.2V 100Ah lithium battery. The SGM-655M ships with one battery (about 5.12 kWh); the SGM-6510M adds a second battery (about 10.24 kWh), a 250A busbar and heavier 1/0 AWG battery cables. It suits cabin, workshop and backup-power buyers who want one box of matched parts rather than sourcing an inverter, panels and battery separately. Against typical DIY builds it saves the compatibility guesswork, but 2,220W of panels is modest for a 6.5kW inverter, so expect to add panels for full output.

This off-grid solar kit pairs a 6500 W inverter with six 370 W monocrystalline solar panels and 51.2 V lithium batteries. The inverter runs on 48 V DC and outputs 120 V and 240 V AC.
The kit comes in two models. Both models include the panels, mounting brackets, breakers and a 50-foot set of solar extension cables for the inverter's PV input.
