SunGold Power 4000W DC 24V Pure Sine Wave Inverter With Charger | Single Phase

The SunGold Power 4000W DC 24V Pure Sine Wave Inverter With Charger Gives 24V Systems 4000 Watts of 120V Output With Automatic Transfer

The SunGold Power 4000W DC 24V Pure Sine Wave Inverter With Charger is a single phase LFP Series unit that combines a 4000W low-frequency pure sine wave inverter, a 50A battery charger and an AC auto-transfer switch. It runs from a 24V battery bank, accepts 120VAC from the grid or a generator, and supplies 120VAC to your loads.

It fits RVs, trailers, motorhomes, truck campers and backup or off-grid systems that run on 24V. A 12000W surge rating covers tools and equipment with high start-up current, and the unit switches between battery and AC power on its own.

SunGold Power 4000W DC 24V Pure Sine Wave Inverter With Charger Features

4000W Output and a 4HP Motor Rating

The inverter supplies 4000W continuously and 12000W for 20 seconds, a 300% surge capacity. SunGold rates the 4KW models to start a 4HP electric motor, which gives headroom for compressors, pumps and shop tools.

50A Charger for 24V Banks

With AC connected, the PFC charger refills a 24V bank at 50A ±5A. The maximum can be dialed down from 100% with a linear switch, and nine battery type settings cover gel, AGM, sealed lead acid, lithium and LiFePO4 profiles.

Low Idle Consumption

Idle power is 48W with power saver off and 19W with power saver on. In power saver mode, the inverter checks for a load and returns to full output when something above 25W turns on.

Battery Priority for Solar Systems

AC priority is the default. Set SW5 to battery priority and the inverter runs your loads from the bank, switching to AC only when the battery reaches its low voltage alarm point, then returning to battery once it is charged. This inverter has no built-in solar controller, so solar panels charge the bank through an external charge controller.

Automatic Generator Start

When battery voltage runs low, the inverter can send a start signal to a generator that has an auto start function, then turn it off after charging. A 15-second delay before transfer gives the generator time to reach a stable output.

Automatic Neutral-to-Ground Switching

As a 120V single phase model, it bonds output neutral to safety ground in inverter mode and opens that bond when qualified external AC is connected. That avoids two neutral-to-ground connections in a vehicle or boat. It can be disabled where local code requires it.

Real-World Applications

24V RVs and motorhomes. Run 120V appliances from the house bank and recharge on shore power through the same unit.

Solar cabins. Pair the inverter with a solar charge controller and run in battery priority, with a generator as backup.

Home backup. Keep essential 120V circuits powered through outages with automatic transfer.

Mobile workshops. Power saws, drills and air compressors from a 24V bank on the road.

How It Compares to Common Alternatives

Versus the 4000W 12V version. The 12V model has the same 4000W and 12000W ratings, a 120A ±5A charger and two cooling fans. The 24V model uses one fan and works with a 24V bank instead.

Versus the 3000W 24V model. The 3000W version has a 9000W surge, a 3HP motor rating and a 40A ±5A charger, so this model adds 1000W of continuous output and more charge current.

Versus an inverter with built-in solar charging. This unit has no solar input. If you already have a charge controller, or want to choose one separately, a dedicated inverter charger keeps the two parts independent.

Is This 24V Inverter Charger the Right Fit

• Battery bank. Requires a 24V bank. The inverter starts at 20.0Vdc and restarts at 26Vdc after a low voltage shutdown.
• Solar. Needs an external solar charge controller. Panels cannot connect directly.
• Cabling. SunGold lists AWG1/0 as the minimum DC cable for a 3 meter run on 4KW 24V models.
• AC source. 120VAC grid or generator power, within 90 to 135VAC or 100 to 135VAC.
• Size. 22 x 9.1 x 7.5 inches and 54 lb.

This may be a good fit if

• You run a 24V battery bank
• You need 120V output only
• You already have a solar charge controller
• Your loads stay within 4000W

Common Questions

Can I Connect 24V Solar Panels Directly to This Inverter?

No. It does not have a built-in solar controller. To charge from solar panels, add an external solar charge controller.

What Is the Idle Wattage?

It draws 19W in power saver mode and 48W with power saver off.

When Does the Low Battery Alarm Sound?

The alarm sounds between 21.0Vdc and 22.0Vdc. The trip point is 20.0Vdc or 21.0Vdc, chosen with SW1.

Can It Run on Battery Priority?

Yes. SW5 switches it from the default AC priority to battery priority, which suits solar systems that use the grid as backup.
