The SunGold Power 4000W DC 12V Split Phase Pure Sine Wave Inverter With Charger Delivers 120V and 240V Power From a 12 Volt Battery Bank

The SunGold Power 4000W DC 12V Split Phase Pure Sine Wave Inverter With Charger is a low frequency inverter charger that produces split phase 120/240 volt pure sine wave power from a 12 volt battery bank. It provides two 120 volt legs, so it can feed a standard 120/240V panel and run both 120 volt loads and 240 volt appliances.

Like the rest of SunGold's LFP series, it combines an inverter, a battery charger, and an automatic transfer switch. It accepts 240VAC from the grid or a generator, passes that power through to your loads, and recharges your batteries at up to 120 amps.


SunGold Power 4000W DC 12V Split Phase Pure Sine Wave Inverter With Charger Features

Split Phase 120V and 240V Output

Two 120V legs make this inverter suitable for small homes, cabins, and businesses with a 120/240V electrical panel. You can run 120V lighting and outlets alongside 240V equipment such as well pumps, provided the total load stays within the inverter's rating.

4000 Watts Continuous and 12000 Watts Surge

The low frequency transformer supports a 12000 watt surge for 20 seconds, giving motor loads the startup power they need while 4000 watts continuous covers steady use.

120 Amp Battery Charger

With 240VAC input present, the built-in 3-step charger delivers up to 120 amps (±5A). Nine battery type settings and an adjustable 0 to 100 percent charge current let you set it up for lithium, AGM, gel, or flooded batteries.

Automatic Transfer and Wide Input Range

Typical transfer time is 10ms. The AC input range can be set to 140 to 270VAC or 184 to 253VAC with SW2, which helps when running from a generator whose voltage varies.

AC or Battery Priority and Generator Start

Choose AC priority for backup or battery priority (SW5) for solar-charged systems. The inverter can automatically start and stop a compatible generator based on battery voltage.

LCD Display, Remote Control, and BTS Cable

SunGold includes a remote control and battery temperature sensor cable. Power saver mode reduces idle draw from 45 watts to 18 watts, and output frequency can be set to 50 or 60Hz with SW4.


Real-World Applications

Small homes and cabins. Feed a 120/240V panel from a 12V battery bank for lights, outlets, and 240V appliances.

Boats and RVs. Provide split phase power for onboard systems that use both 120V and 240V circuits.

Small business backup. Keep refrigeration, lighting, and equipment running during outages with automatic transfer.

Generator-supported off-grid systems. Use automatic generator start with a 240V generator to keep the battery bank charged.


How It Compares to Common Alternatives

Versus the single phase 4000W 12V model. The single phase version takes 120VAC input and provides only 120V output. This split phase model requires 240VAC input and adds 240V output.

Versus 24V and 48V split phase inverters. Higher battery voltages reduce DC current and cable size. This 12V model makes sense when you already have a 12V battery bank.

Versus grid-tie or stackable systems. SunGold notes this unit cannot be stacked and cannot run on the same grid with other inverters, such as microinverters.


Is This Inverter Charger the Right Fit

  • Battery bank. Requires a 12 volt battery bank sized for 4000 watt loads.
  • AC input. Requires 240VAC input from the grid or a generator. It will not charge from a 120V-only source.
  • Loads. Supports both 120V and 240V loads within its 4000 watt rating.
  • Space. Plan for a 25.6 x 9.1 x 7.5 inch, 58.9 pound unit.

This may be a good fit if

  • You need 240V output from a 12V battery bank
  • You have a 240V generator or utility supply
  • You want a 120 amp charger
  • You want automatic transfer and generator start

Common Questions

Will the Charger Work on 120 Volts?

No. SunGold specifies 240V AC input, 120V and 240V AC output, and 12V DC.

Can It Work With Enphase Microinverters on the Same Grid?

No. SunGold says it cannot work with other inverters on the same grid and is not stackable.

What Is the Idle Power?

45 watts with power saver off and 18 watts with power saver on.

What Warranty Does SunGold Provide?

SunGold lists a 12 month warranty for this model.
