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

The SunGold Power 3kW 24V Inverter 120VAC Off-Grid Solar Kit Puts an 80A MPPT Inverter, 800W of Solar and Two 24V Lithium Batteries in One Package

The SunGold Power 3kW 24V Inverter 120VAC Off-Grid Solar Kit is a compact 24V solar system. Its 3000W solar inverter charger has an 80A MPPT controller built in, so the four 200W monocrystalline panels connect to the inverter without a separate charge controller. Two 24V 100Ah LiFePO4 batteries with Bluetooth store the energy.

The kit suits tiny homes, cabins, sheds and camper setups that need 120V AC power from a simple layout. It also includes a 160A DC breaker, a 25A PV breaker, 4AWG cable, four sets of Z-brackets and 50 feet of PV extension cable.

SunGold Power 3kW 24V Inverter 120VAC Off-Grid Solar Kit Features

All-in-One 3000W Inverter Charger

One unit combines a 3000W pure sine wave inverter, an 80A MPPT solar charger and a 40A AC charger. Peak power is 6000VA, and output is 120VAC at 50 or 60Hz. Fewer separate components means less to mount and wire.

Room to Grow the Solar Array

The inverter accepts up to 4000W of PV input, with a 120-450VDC operating range and a 450V open-circuit limit. The 800W array uses only part of that, so you can add panels later as your needs grow.

Two 24V 100Ah Lithium Batteries

Each battery stores 2560Wh at 25.6V. SunGold recommends connecting these batteries in parallel, which keeps the bank at 24V and adds capacity. Each one has a built-in 100A BMS, an LCD for voltage and state of charge, and an IP65 rating.

Switchover in 10 Milliseconds

If grid or generator power drops, or solar charging falls short, the inverter shifts to battery power within 10ms. That keeps most electronics running through the change, much like a UPS.

Four Charging Modes

AC Priority, Solar Priority, Only Solar and Mains and Solar hybrid charging let you decide how the batteries refill. The display shows system data and operating status at a glance.

Self-Heating Batteries

Each battery warms itself when its core temperature falls below 33.8°F (1°C) and stops at 42.8°F (6°C). That helps the bank keep charging in cold weather.

Generator Auto-Start

Dry contacts on the inverter can send a signal to start a generator automatically. Paired with the 40A AC charger, that gives you a backup way to refill the bank.

Real-World Applications

Tiny homes and cabins. Run lights, a fridge, electronics and small appliances on 120V from solar and lithium storage.

Sheds and workshops. Add AC power to an outbuilding with one inverter, two batteries and four panels.

Campers and trailers. The 24V batteries and 200W panels suit RV and camper use, with generator charging when you need it.

Backup for key circuits. The 10ms switchover keeps selected 120V loads on when the grid goes down.

How It Compares to Common Alternatives

Versus a kit with a separate charge controller. Here the MPPT controller is built into the inverter. You mount one main unit, wire the panels straight to it, and read everything on one display.

Versus the 60A MPPT version of this inverter. SunGold's SPH302460A works with a lower-voltage 30-108Vdc PV input and tops out at 1600W of solar. The SPH302480A in this kit handles up to 4000W at 120-450VDC.

Versus running a generator for every outage. The inverter moves loads to battery power in 10ms and solar refills the bank, so a generator becomes a backup charger instead of the main power source.

Is This Solar Kit the Right Fit

• Battery voltage. The inverter runs on a 24V bank, with a minimum start-up voltage of 22V.
• AC output. Output is 120VAC. There is no 240V output.
• PV voltage. The array must reach the 120VDC operating minimum and stay below 450V open circuit.
• Monitoring. Wi-Fi or GPRS remote monitoring is optional at extra cost and is not part of this kit. The batteries have Bluetooth.
• Space. The inverter measures 15.0 x 11.0 x 4.1 inches and weighs 16.8lbs.

This may be a good fit if

• You want a simple 24V system with one main unit
• You run 120V appliances, lights and electronics
• You plan to add solar panels later
• You want lithium batteries with Bluetooth

Common Questions

Does the Kit Need a Separate Charge Controller?

No. The inverter has an 80A MPPT solar charge controller built in, and the panels connect to it directly.

Which Battery Types Does the Inverter Support?

It works with 24V AGM, sealed, gel, flooded and lithium batteries, plus a user mode for custom settings. This kit ships with LiFePO4 batteries.

How Much Energy Does Each Battery Store?

Each 24V 100Ah battery is rated at 2560Wh, at a nominal 25.6V.

Can I Charge From a Generator?

Yes. The 40A AC charger accepts 90VAC to 140VAC from the grid or a generator, and the dry contacts can auto-start a generator.
