The SunGold Power SGR-20K30E Pairs Two 10kW Inverters With 14,400W of Solar and 30.72kWh of LiFePO4 Storage

The SunGold Power 20kW 48VDC Off-Grid Solar Kit (SGR-20K30E) is a complete off-grid solar kit built around two 10kW split-phase all-in-one inverters (SPH10048P) running in parallel. It includes 32 x 450W bifacial N-type monocrystalline solar panels for 14,400W of solar, 6 x 51.2V 100Ah LiFePO4 server rack batteries (SG48100P) for 30.72kWh of storage, and the breakers, cables, and mounting hardware SunGold lists for the system.

Two 10kW inverters in parallel provide 20kW of 120/240V split-phase output for high-demand appliances such as air conditioners, well pumps, refrigerators, and power tools. Six SG48100P batteries in an enclosed cabinet provide 30.72kWh of storage.


SunGold Power SGR-20K30E 20kW Solar Kit Features

20kW Split-Phase Inverters

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. The kit includes two units for 20kW of combined output.

30.72kWh of LiFePO4 Storage

Each SG48100P is a 51.2V, 100Ah (5.12kWh) lithium iron phosphate battery in a 3U server rack format. 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 RS485 or CAN. It is certified to UL1973 and is rated IP20 for indoor installation. Six batteries combine for 30.72kWh of storage, housed in the included enclosed battery cabinet.

14,400W 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 32-panel array produces about 57.6kWh 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, and Z-brackets for mounting the panels, 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. SunGold lists up to 32 SG48100P batteries in parallel, so storage can grow with your needs. Add panels within the inverter solar input limits as your energy use grows.


Real-World Applications

Large off-grid homes. Run air conditioners, well pumps, and full household loads.

Farms and ranches. Power pumps, barns, and equipment.

Light commercial sites. Support offices, shops, and remote facilities.

Extended backup. Ride through long outages with a large battery bank.


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-16K25E. The SGR-16K25E uses two 8kW inverters and five batteries with the same 32-panel array.


Is This Solar Kit the Right Fit

  • Daily energy. The array produces about 57.6kWh per day at four peak sun hours. Compare that with your average daily use.
  • Loads. The inverters provide 20,000W 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 57.6kWh or less
  • You plan to expand the system later

Common Questions

How Much Energy Will This Kit Produce?

At four peak sun hours, the 14,400W array produces about 57.6kWh 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?

SunGold lists up to 32 SG48100P batteries in parallel, so storage can grow with your needs.

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.
