SunGold Power 10kW 48VDC Off-Grid Solar Kit | 5500W Solar

The SunGold Power SGM-10K20 Pairs a 10kW Inverter With 5,500W of Solar and 20.48kWh of LiFePO4 Storage

The SunGold Power 10kW 48VDC Off-Grid Solar Kit (SGM-10K20) is a complete off-grid solar kit built around a 10kW split-phase all-in-one inverter (SPH10048P). It includes 10 x 550W monocrystalline solar panels for 5,500W 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.

A single 10kW split-phase inverter, ten 550W panels, and four 5.12kWh wall-mounted batteries make this a capable whole-home off-grid system with 20.48kWh of storage.

SunGold Power SGM-10K20 10kW Solar Kit Features

10kW Split-Phase Inverter

The SPH10048P is a 10,000W all-in-one inverter with 120/240VAC split-phase pure sine wave output, 20,000W of peak power, and a 6 HP motor loading rating. Two MPPT trackers accept up to 11,000W of solar, and the inverter charges batteries at up to 200A from solar or 120A from the grid or a generator. It is certified to UL1741 and includes Wi-Fi monitoring.

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.

5,500W Solar Array

The 550W monocrystalline PERC panels (SG550WM) use 144 half-cut cells, carry UL61730 certification and CEC listing, and are rated for 2,400Pa wind and 5,400Pa snow loads. SunGold backs them with a 12-year material and workmanship warranty and a 25-year power output warranty. At four peak sun hours, the 10-panel array produces about 22kWh per day. Actual output depends on location, season, tilt, and shading.

Built-In MPPT Solar Charging

The inverter has built-in MPPT solar charging, so the panels connect directly to the inverter 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 SPH10048P inverters can be paralleled for more 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-10K25S. The SGR-10K25S uses the same inverter with 12 panels and five server rack batteries in an enclosed cabinet.

Is This Solar Kit the Right Fit

• Daily energy. The array produces about 22kWh per day at four peak sun hours. Compare that with your average daily use.
• Loads. The inverter provides 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 22kWh or less
• You plan to expand the system later

Common Questions

How Much Energy Will This Kit Produce?

At four peak sun hours, the 5,500W array produces about 22kWh 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 inverter.

Can I Add More Batteries Later?

You can add more SG48100M batteries later to extend storage.

Can It Charge From a Generator?

Yes. The inverter accepts 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.
