SunGold Power 2000W DC 12V Pure Sine Wave Inverter With Charger

The SunGold Power 2000W DC 12V Pure Sine Wave Inverter With Charger Combines an Inverter, Charger, and Transfer Switch in One Low Frequency Unit

The SunGold Power 2000W DC 12V Pure Sine Wave Inverter With Charger is part of SunGold's LFP series of low frequency inverter chargers. It takes power from a 12 volt battery bank and turns it into clean 120 volt pure sine wave AC, and when shore power, grid power, or a generator is connected, it passes that power through to your loads while recharging the batteries with its built-in 70 amp charger. An automatic transfer switch handles the hand-off between the two in about 10 milliseconds, so most connected equipment never notices the change.

That three-in-one design makes it a practical fit for RVs, work trucks, cabins, and home backup systems that run on 12 volts. It is rated for 2000 watts continuous with a 6000 watt surge for up to 20 seconds, which gives it the headroom to start motors, compressors, and tools that briefly draw several times their running wattage.

SunGold Power 2000W DC 12V Pure Sine Wave Inverter With Charger Features

Low Frequency Design With a 300 Percent Surge Rating

Low frequency inverters use a heavy transformer rather than lightweight high frequency switching electronics. The result is a unit that weighs about 42 pounds, and one that can hold a 6000 watt surge for 20 seconds. That matters when you are starting a refrigerator, a well pump, a microwave, or a power tool, where the startup draw can be much higher than the running load.

Pure Sine Wave Output for Sensitive Electronics

The inverter produces pure sine wave 120VAC, the same type of power that comes from a household outlet. Laptops, televisions, CPAP machines, chargers, and appliances with motors run the way they were designed to, without the buzzing and extra heat that modified sine wave power can cause. Output frequency can be set to 50 or 60Hz with the SW4 switch.

Built-In 70 Amp Multi-Stage Battery Charger

When AC input is present, the integrated charger recharges your battery bank at up to 70 amps (±5A) using a 3-step charging profile. SunGold provides 9 battery type settings, and the charge current can be adjusted from 0 to 100 percent or switched off entirely. That flexibility lets you match the charger to your battery chemistry and capacity, or to a small generator that cannot supply a full charging load.

Automatic Transfer Switch With 10 Millisecond Typical Transfer

When AC input drops out, the unit switches your loads to inverter power with a typical transfer time of 10ms. AC input range can be set to 90 to 135VAC or 100 to 135VAC with the SW2 switch, so you can tune how tolerant the inverter is of a sagging generator or campground pedestal.

AC Priority or Battery Priority Operation

The inverter ships in AC priority mode, which uses incoming grid or shore power first and keeps your batteries in reserve. Flip the SW5 switch to battery priority and the inverter will run from your batteries first, which is useful when a solar array is keeping the bank charged and you only want to fall back on the grid or a generator when the batteries run low.

Automatic Generator Start

With a compatible generator, the inverter can start the generator when battery voltage gets low and shut it off again once charging is finished. For off-grid cabins and remote equipment, that means the system can look after itself without someone standing by to pull a cord.

Remote Control, Battery Temperature Sensor, and GFCI Outlet

SunGold includes a remote control and a battery temperature sensor (BTS) cable in the box. The BTS lets the charger adjust to battery temperature, and the remote lets you monitor and control the inverter from a more convenient spot than the battery compartment. The unit also has a GFCI outlet, an LCD display, and a power saver mode that cuts idle consumption from 28 watts to 13 watts.

Real-World Applications

RVs, campers, and trailers. Run a microwave, coffee maker, or television from your house batteries while boondocking, then let the built-in charger top them off when you plug into shore power.

Home backup power. Keep a refrigerator, lights, internet equipment, and a few outlets running through an outage with a 12V battery bank. With AC priority, the inverter stays on standby and takes over automatically when the grid fails.

Off-grid cabins and sheds. Pair it with batteries and a separate solar charge controller for a simple 12V system. Battery priority mode and automatic generator start help stretch your stored energy.

Work trucks and mobile service. Power saws, drills, chargers, and small compressors from a truck-mounted battery bank, with enough surge capacity to start motor loads.

How It Compares to Common Alternatives

Versus high frequency inverters. High frequency units are lighter and usually less expensive, but they typically have far lower surge ratings. This low frequency model trades extra weight for a 6000 watt, 20 second surge that handles motor starting more comfortably.

Versus an inverter plus a separate charger. Buying an inverter, a battery charger, and a transfer switch separately means more wiring and more parts to coordinate. This unit combines all three and manages the switching for you.

Versus all-in-one solar inverters. This model does not include a solar charge controller. If you plan to add solar panels, you will need a separate charge controller, or you may want to consider an all-in-one solar inverter instead.

Is This Inverter Charger the Right Fit

• Battery bank. It requires a 12 volt battery bank and works with lithium, AGM, gel, and flooded batteries using the selectable charge settings.
• Load size. Your combined running load should stay at or below 2000 watts, with startup surges under 6000 watts.
• AC input. It takes 120VAC input from the grid, shore power, or a generator and provides 120VAC output.
• Installation space. At 22 x 9.1 x 7.5 inches and 41.9 pounds, it needs a solid mounting location near the batteries.

This may be a good fit if

• You want inverter, charger, and transfer switch functions in one unit
• You need strong surge capacity for motors and compressors
• You run a 12V system in an RV, truck, cabin, or backup setup
• You want automatic generator start capability

Common Questions

What Is the Idle Draw on 12V?

SunGold lists idle consumption at 28 watts and 13 watts in power saver mode. In its FAQ, SunGold puts standby current at about 2 amps.

Does It Include a Solar Charge Controller?

No. This is an inverter charger with an AC charger and transfer switch. Solar charging requires a separate charge controller.

What Size Ground Wire Does It Need?

SunGold recommends 1/0 AWG wire for the chassis ground.

What Happens When the Batteries Run Low in Battery Priority Mode?

The inverter switches to AC input and charges the batteries, then switches back to battery power once they are recharged.

Can I Disable the Charger?

Yes. The charge current is adjustable from 0 to 100 percent, and the charger can be turned off.
