SunGold Power 10kW 48VDC Off-Grid Solar Kit With Powerwall Batteries | 5400W Solar

The SunGold Power SGM-10M2T Pairs Two 5kW Inverters With 5,400W of Solar and 20.48kWh of LiFePO4 Storage

The SunGold Power 10kW 48VDC Off-Grid Solar Kit With Powerwall Batteries (SGM-10M2T) is a complete off-grid solar kit built around two 5000W all-in-one inverters (SPH5048P) running in parallel. It includes 12 x 450W bifacial N-type monocrystalline solar panels for 5,400W of solar, 4 x 51.2V 100Ah LiFePO4 Powerwall batteries (SG48100M) for 20.48kWh of storage, and the breakers, cables, and mounting hardware SunGold lists for the system.

Two 5000W inverters run in parallel to provide 10kW of 120/240V split-phase power, and four wall-mounted 5.12kWh Powerwall batteries provide 20.48kWh of storage. Twelve 450W bifacial panels make up the 5,400W array.

SunGold Power SGM-10M2T 10kW Solar Kit Features

10kW Split-Phase Inverters

The SPH5048P is a 5000W all-in-one inverter with a built-in 100A MPPT solar charge controller and AC charger. It delivers 120VAC pure sine wave output with up to 10,000VA of peak power, accepts up to 5,500W of solar at up to 500V open circuit, and supports optional Wi-Fi monitoring through an app. The kit includes two units for 10kW of combined output.

20.48kWh of LiFePO4 Storage

Each SG48100M is a wall-mounted 51.2V, 100Ah (5.12kWh) lithium iron phosphate battery. SunGold rates it for 7,000 or more cycles at 80% depth of discharge with a 15-year design life, and it communicates with the inverter over RS232, RS485, or CAN. It is certified to UL1973 and is rated IP20 for indoor installation. Four batteries combine for 20.48kWh of storage.

5,400W Solar Array

The 450W bifacial N-type panels (SGN-450-BDG5) use 96 N-type monocrystalline cells and can collect reflected light from the rear side when mounted with open space behind them. Each panel is UL61730 and CEC listed and carries a 12-year material and workmanship warranty with a 30-year linear power warranty. At four peak sun hours, the 12-panel array produces about 21.6kWh per day. Actual output depends on location, season, tilt, and shading.

Built-In MPPT Solar Charging

The inverters have built-in MPPT solar charging, so the panels connect directly to the inverters without a separate charge controller. That keeps wiring simpler and reduces the number of components to mount.

Breakers, Cables, and Mounting Hardware

SunGold includes DC and PV breakers, battery and inverter cables, 50-foot solar extension cables, Z-brackets for mounting the panels, and a busbar, all sized for this kit. SunGold also publishes a wiring diagram for the kit on its website. Having matched protection and cabling in the box saves sourcing time and helps keep the installation consistent.

Room to Expand

Up to six identical SPH5048P inverters can run in parallel for single-phase 120V, split-phase 120/240V, or three-phase 208V output. You can add more SG48100M batteries later to extend storage. Add panels within the inverter solar input limits as your energy use grows.

Real-World Applications

Off-grid homes. Run household loads including refrigerators, washers, and well pumps.

Homesteads and farms. Power barns, shops, and pumps far from the grid.

Whole-home backup. Keep power on through extended outages.

Workshops and offices. Support tools, computers, and HVAC loads.

How It Compares to Common Alternatives

Versus buying components separately. A kit pairs an inverter, batteries, and panels that SunGold has matched for voltage and current, with breakers and cables sized for the system and a published wiring diagram.

Versus a fuel generator alone. Solar and batteries run quietly with no fuel deliveries. Many off-grid owners still keep a generator for long cloudy stretches, and the inverter can charge the batteries from one.

Versus the SGR-10K2M. The SGR-10K2M uses the same paralleled inverters with 450W monocrystalline panels and server rack batteries.

Is This Solar Kit the Right Fit

• Daily energy. The array produces about 21.6kWh per day at four peak sun hours. Compare that with your average daily use.
• Loads. The inverters provide 10,000W of continuous 120/240VAC split phase output. This kit supplies 240V for well pumps, dryers, and other 240V appliances.
• Battery location. The batteries are rated IP20 and belong in a dry, indoor space.
• Mounting. Z-brackets are included for flat surface mounting. Ground mounts or racking for other mounting styles are sold separately.
• Installation. Have a qualified electrician install the system and follow local codes and permit requirements.

This may be a good fit if

• You want a matched solar, battery, and inverter package
• You need 120V and 240V power
• Your daily energy use is around 21.6kWh or less
• You plan to expand the system later

Common Questions

How Much Energy Will This Kit Produce?

At four peak sun hours, the 5,400W array produces about 21.6kWh per day. Production varies with your location, season, and panel orientation.

Does It Need a Separate Charge Controller?

No. Solar charging is built into the inverters.

Can I Add More Batteries Later?

You can add more SG48100M batteries later to extend storage.

Can It Charge From a Generator?

Yes. The inverters accept AC input from the grid or a generator to charge the batteries and pass power to loads.

Is Installation Included?

No. The kit ships as components. We recommend a qualified electrician for installation and permitting.
