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

The SunGold Power 4000W DC 24V Split Phase Pure Sine Wave Inverter With Charger Runs 240V Well Pumps and 120V Circuits From One 24V Bank

The SunGold Power 4000W DC 24V Split Phase Pure Sine Wave Inverter With Charger is three products in one: an inverter that turns 24V DC battery power into AC, a built-in 50A battery charger that recharges from the grid or a generator, and a transfer switch that moves loads between shore power and battery in about 10 milliseconds.

It requires 240VAC input and outputs 120V and 240V split phase power, with two hot legs for a home or business that already has a 240V panel. SunGold builds it for small homes, businesses, RV systems, trailers and boats, in off-grid setups or as an emergency backup supply.

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

Two Legs for 120V and 240V Loads

The split phase output provides 120V circuits and 240V circuits from one 4000W inverter. That suits well pumps, shop equipment and appliances that need 240V, alongside lighting and outlets on 120V.

12000W Surge for Pump and Motor Starts

Surge capacity is 12000W for 20 seconds, and SunGold rates the 4KW models to start a 4HP motor. SunGold builds the LFP Series with heavy transformers to meet the start-up demands of inductive loads.

Built-In 50A Charger

The charger refills the 24V bank at 50A ±5A from grid or generator power, with a 3-step charge profile and an adjustable limit from 0% to 100%. Nine battery type settings include LiFePO4, lithium, AGM and gel.

Wide or Narrow AC Input

SW2 sets the accepted AC input to 140 to 270VAC or 184 to 253VAC. The wide range keeps the inverter on generator power without frequent switching to battery, while the narrow range protects sensitive electronics.

Battery Priority and Auto Generator Start

SW5 changes the default AC priority to battery priority for solar or wind systems with utility backup. When the battery gets low, the inverter can start a generator with auto start capability and stop it after charging.

Protections and Status Display

The inverter protects against AC input over and under voltage, low and high battery, over temperature, overload, short circuit and backfeed. The LCD and LED indicators show line mode, inverter mode, charge stage and fault conditions.

Real-World Applications

Well pumps. Start and run a 230V deep well pump from a 24V battery bank. SunGold confirms a 1.5HP pump works with this model.

Small homes with a 240V panel. Feed both legs of the panel during outages or off-grid, with the charger refilling the bank from a generator.

Shops and small businesses. Power 240V tools and 120V lights from the same inverter.

RV systems, trailers and boats. Add 240V capability to a 24V platform.

How It Compares to Common Alternatives

Versus the 6000W 24V split phase model. SunGold's manual lists the 6KW at 6000W continuous, 18000W surge, a 6HP motor rating and a 90A ±5A charger on 24V. It also needs heavier DC cable, AWG4/0 against AWG1/0 for this 4KW unit.

Versus a 120V single phase inverter. A 120V-only unit cannot feed 240V pumps or a split phase panel. This model supplies both voltages at once.

Versus separate components. One unit replaces an inverter, a battery charger and a transfer switch, with one set of DC connections and one control panel.

Is This Split Phase Inverter Charger the Right Fit

• AC input. Requires 240VAC input, wired as two hot lines plus ground. An input neutral is not required, and the input neutral must never connect to the output neutral.
• Battery bank. Requires a 24V bank. The low battery alarm sounds at 21.0 to 22.0Vdc and the trip point is 20.0 or 21.0Vdc.
• DC cabling. SunGold recommends 120mm² battery cable for runs within 10m.
• Leg loading. When wired for 120V output on one hot line, that line can carry at most half the rated capacity.
• Size. 22 x 9.1 x 7.5 inches and 55 lb.

This may be a good fit if

• You need to run a 240V well pump
• Your system runs on a 24V bank
• Your charging source supplies 240VAC
• You want 120V and 240V from one unit

Common Questions

Can It Start a 1.5HP 230V Deep Well Pump?

Yes. SunGold confirms it can run a 1.5HP, 230V, 10.6A two-wire deep well pump from a 220Ah 24V AGM battery pack.

What Size Battery Cable Should I Use?

SunGold recommends 120mm² cable if the cable length is within 10m. Its manual lists AWG1/0 as the minimum for a 3 meter run.

Will the Charger Work With LiFePO4 Batteries?

Yes. Choose the matching setting on the battery type selector, described in the manual. It works as long as your battery voltage falls within that setting's range.

Does the AC Input Need a Neutral?

No. On split phase models, the AC input uses two hot lines and a ground. Never connect the input neutral to the output neutral, or damage will result.
