SunGold Power 3kW 24V Inverter 120VAC Off-Grid Solar Kit | 800W Solar

The SunGold Power SGKT-3PRO Pairs a 3kW Inverter With 800W of Solar and 5.12kWh of LiFePO4 Storage

The SunGold Power 3kW 24V Inverter 120VAC Off-Grid Solar Kit (SGKT-3PRO) is a complete off-grid solar kit built around a 3000W 24V all-in-one inverter (SPH302480A). It includes 4 x 200W monocrystalline solar panels for 800W of solar, 2 x 24V 100Ah LiFePO4 batteries with Bluetooth (LFP24-100A) for 5.12kWh of storage, and the breakers, cables, and mounting hardware SunGold lists for the system.

This compact 24V kit is a straightforward way to run 120V lights, electronics, and small appliances from solar in a cabin, shed, or workshop. The all-in-one inverter has a built-in MPPT controller, so there is no separate charge controller to wire.

SunGold Power SGKT-3PRO 3kW Solar Kit Features

3kW 120V Inverter

The SPH302480A is a 3000W all-in-one inverter for 24V battery banks with 120VAC pure sine wave output and 6,000VA of peak power. A built-in 80A MPPT charge controller accepts up to 4,000W of solar at up to 450V open circuit, and a 40A AC charger can top up the batteries from the grid or a generator.

5.12kWh of LiFePO4 Storage

Each LFP24-100A is a 25.6V, 100Ah (2.56kWh) LiFePO4 battery with an LCD display, Bluetooth monitoring through the SGP Battery app, and self-heating that switches on below about 34°F. The IP65 case and 4,000-plus cycle rating suit demanding environments, and SunGold backs it with a 5-year warranty. Two batteries combine for 5.12kWh of storage.

800W Solar Array

The 200W monocrystalline panels (SG200WM) are a manageable size at 55.1 x 27.6 inches and about 23 pounds each, which makes them easy to handle on roofs, sheds, and small ground mounts. At four peak sun hours, the 4-panel array produces about 3.2kWh 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, 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

You can add more LFP24-100A batteries later to extend storage. The inverter is a standalone unit, so plan its size around your largest expected loads. Add panels within the inverter solar input limits as your energy use grows.

Real-World Applications

Cabins and sheds. Run lights, fans, electronics, and small appliances away from the grid.

RVs, vans, and tiny homes. Power essentials from a compact battery bank.

Emergency backup. Keep a refrigerator, lights, and devices running during outages.

Workshops and outbuildings. Add power where running a utility line would be costly.

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 a 12V kit. A 24V system moves the same power at half the current of a 12V system, which allows smaller cables and less voltage drop.

Is This Solar Kit the Right Fit

• Daily energy. The array produces about 3.2kWh per day at four peak sun hours. Compare that with your average daily use.
• Loads. The inverter provides 3,000W of continuous 120VAC output. Output is 120V only, so 240V appliances are not supported.
• Battery location. The LiFePO4 batteries have IP65 cases, but still need a protected location within their temperature ratings.
• 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
• Your loads run on 120V
• Your daily energy use is around 3.2kWh or less
• You plan to expand the system later

Common Questions

How Much Energy Will This Kit Produce?

At four peak sun hours, the 800W array produces about 3.2kWh 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 LFP24-100A 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.
