SunGold Power 3000W DC 24V Pure Sine Wave Inverter With Charger

The SunGold Power 3000W DC 24V Pure Sine Wave Inverter With Charger Pairs Low Frequency Durability With a 24 Volt Battery Bank

The SunGold Power 3000W DC 24V Pure Sine Wave Inverter With Charger is a low frequency inverter charger from SunGold's LFP series. It converts 24 volt battery power into 120 volt pure sine wave AC, charges the battery bank at up to 40 amps when grid or generator power is connected, and moves your loads between AC input and battery power automatically.

Running at 24 volts cuts the DC current roughly in half compared with a 12 volt system of the same wattage, which means smaller cables and less heat in the wiring. That makes this model a practical choice for cabins, work vehicles, tiny homes, and backup systems built around a 24V battery bank.

SunGold Power 3000W DC 24V Pure Sine Wave Inverter With Charger Features

3000 Watts Continuous With a 9000 Watt Surge

This inverter is rated for 3000 watts of continuous output and a 300 percent surge of 9000 watts for 20 seconds. The low frequency transformer design is what makes that surge possible, giving refrigerators, pumps, compressors, and power tools the startup current they need.

Pure Sine Wave 120VAC Output

The output is clean pure sine wave power that works with laptops, televisions, medical equipment, chargers, and motor-driven appliances. Output frequency is selectable at 50 or 60Hz with the SW4 switch.

40 Amp Three-Step Charger With 9 Battery Settings

When AC input is available, the built-in charger supplies up to 40 amps with a 3-step charging profile. You can choose from 9 battery type settings and set the charge current anywhere from 0 to 100 percent, or turn the charger off.

Fast Automatic Transfer

If grid or generator power is lost, the unit switches to inverter power with a typical transfer time of 10ms. AC input range is selectable between 90 to 135VAC and 100 to 135VAC with SW2.

AC Priority, Battery Priority, and Generator Start

AC priority is the default. Battery priority, set with SW5, lets a solar-charged battery bank carry the load first. The inverter can also start a compatible generator when the battery is low and stop it once charging is done.

Remote, BTS Cable, LCD, and GFCI Outlet

SunGold includes a remote control and battery temperature sensor cable. The unit has an LCD display, a GFCI outlet, and a power saver mode that reduces idle consumption from 39 watts to 16 watts.

Real-World Applications

Off-grid cabins and tiny homes. Run a refrigerator, lights, a microwave, and small tools from a 24V battery bank, with generator backup for cloudy stretches.

Work trucks and mobile workshops. Power saws, drills, chargers, and compressors from a 24V bank with less current in the cabling than a 12V setup.

Home backup. Keep essential circuits running through outages with automatic transfer from grid to battery.

RVs and specialty vehicles. Provide household AC from a 24V house battery with shore power charging.

How It Compares to Common Alternatives

Versus the 12V 3000W model. The 12V version has a larger 90 amp charger, but at 12V it pulls twice the DC current. The 24V model is easier to wire for the same output.

Versus the 4000W 24V model. The 4000W version adds 1000 watts of output and a 50 amp charger. The 3000W unit is a good fit when your loads stay at or below 3000 watts.

Versus all-in-one solar inverters. This model does not include an MPPT solar controller, so solar charging requires a separate controller.

Is This Inverter Charger the Right Fit

• Battery voltage. Your battery bank must be 24 volts.
• Load size. Continuous loads up to 3000 watts, with surges up to 9000 watts.
• AC service. 120VAC input and 120VAC single phase output.
• Space. Plan for a 22.05 x 9.1 x 7.5 inch, 48.5 pound unit.

This may be a good fit if

• You run a 24V battery bank
• You want inverter, charger, and transfer switch in one unit
• You need strong surge capacity for motor loads
• You want automatic generator start

Common Questions

Does the Inverter Shut Off at the Low Battery Alarm?

Without AC input, SunGold says the low battery alarm triggers at 21V and the inverter shuts down at 20V. With AC input connected, it begins charging the battery instead.

Will It Work With Lithium Batteries?

Yes, as long as the battery bank is 24 volts. LiFePO4 batteries with a built-in BMS do not need an additional BMS.

How Long Will It Run on Battery?

Runtime depends on battery capacity, your load, and depth of discharge rather than on the inverter itself.

Where Should It Be Installed?

SunGold recommends a ventilated, dry, dust-free location close to the batteries to keep cable runs short.
