The SunGold Power 6.5kW 48VDC Off-Grid Solar Kit (SGM-655M) gives you a 120/240V split phase inverter from day one with a single battery to start. It includes a 6500W 48V solar inverter with two MPPT inputs, six 370W mono black panels and one 51.2V 100Ah wall-mounted LiFePO4 battery rated at 5.12kWh.
SunGold describes this kit as a starter package for an off-grid cabin or shop. It fits when you need 240V capability now but would rather add storage over time, since the battery is designed to expand in parallel.
The SPH6548P delivers 6500W of rated output with a 13000VA peak, at 120/240V split phase or 120V single phase. You get 240V circuits without pairing a second inverter.
Two MPPT controllers each accept up to 5000W and 550V open circuit, within a 150-450Vdc operating range. The 2220W array uses part of that capacity, leaving room to add panels.
The SG48100M is a 51.2V 100Ah LiFePO4 battery rated for 7000 cycles, with an LCD and a BMS that watches cell voltage, current and temperature. It communicates over CAN, RS485 or RS232.
The 370W panels use 182mm half-cut PERC cells at 20.31% module efficiency. They have IP68 junction boxes and pass load tests of 5400Pa for snow and 2400Pa for wind.
The inverter charges from grid or generator power at up to 80A, and solar plus AC charging together reach 140A. That helps refill the battery when solar alone falls short.
Charging modes are Hybrid, Utility Priority, Solar Priority and Only Solar. Output modes are Utility Priority, Solar and Utility Hybrid, Solar Priority and Inverter Priority.
A first off-grid cabin. Get split phase power in place now and grow storage as you learn your daily use.
Shops with 240V circuits. Run 240V equipment and 120V outlets from one inverter.
Generator-assisted sites. Use the 80A AC charger to refill the battery from a generator after cloudy days.
Phased builds. Start with this kit and add batteries, panels or paralleled inverters later.
Versus the SGM-6510M version. SunGold also offers this kit with two batteries for 10.24kWh. That version swaps the single 4AWG cable set for two 1/0 AWG battery cables and a 250A busbar.
Versus a 120V-only kit. Split phase output means 240V circuits work without a second inverter.
Versus separate inverter and charge controllers. Two MPPT inputs, an AC charger and the inverter share one unit and one display.
This may be a good fit if
The SG48100M supports up to 63 batteries in parallel. SunGold advises against mixing new and old batteries, so talk with us before adding units.
Yes. It can run 120V single phase as well as 120/240V split phase.
Yes. The inverter supports CAN and RS485 communication with SunGold batteries. If the lithium battery goes dormant, solar or AC power can wake it.
Up to six, for up to 39KW in single phase, split phase or 208V three phase.
The SunGold Power 6.5kW 48VDC Off-Grid Solar Kit gets 6500W of 120/240V power and 2220W of solar running now, with a 5.12kWh battery you can build on. At Outbound Power, we help customers plan off-grid systems that grow in stages. If you have questions, our team is happy to help.
