4000W DC 24V Split Phase Pure Sine Wave Inverter With Charger 120/240VAC

24V Pure Sine Wave Inverter — Authentic 4000W Split Phase 120/240VAC With Charger

The 24v pure sine wave inverter SunGoldPower LFP 4000W DC 24V AC 120/240V split phase inverter charger is a high quality low frequency three-in-one power system — inverter battery charger and automatic transfer switch — built for whole house small home business RV trailer and boat applications. The split phase architecture produces two legs of 110V enabling connection to 220V panels — with 110/120V or 220/230/240VAC selectable output and 50/60Hz via SW4. The built-in 50A battery charger and 10ms automatic transfer switch make this the most complete standalone power management solution available at 4000W 24V.

Product Details

Three-In-One Design

The 24v pure sine wave inverter SunGoldPower LFP unit combines all three essential power management functions in a single low frequency chassis:

Inverter Function — transforms 24V DC battery power into clean 120/240V AC electricity at sinusoidal pure sine wave quality — powering all residential and commercial appliances and electronics without harmonic distortion.

Battery Charger Function — the built-in 50A charger uses grid or generator 240VAC input to recharge the connected battery bank — efficiently restoring battery capacity during periods of grid availability or generator operation.

Transfer Switch Function — the automatic transfer switch transitions between shore power and battery-inverter output within 10 milliseconds — fast enough that sensitive electronics do not register the transition — providing seamless power continuity during grid outages and grid restoration.

24V Architecture Advantage

The 24v pure sine wave inverter architecture delivers specific efficiency advantages over 12V alternatives at equivalent 4000W output levels:

• Lower Current — 24V systems require half the current of 12V systems at equivalent power — reducing cable sizing requirements and connection resistance losses throughout the battery bank and inverter wiring
• Better Efficiency — lower transmission current reduces I²R losses in battery cables and connections — improving overall system efficiency particularly over longer cable runs
• RV And Marine Compatibility — 24V battery systems are widely used in larger Class A and Class B motorhomes marine vessels and commercial vehicle auxiliary power applications

Inverter Sinusoidal Output

The inverter sinusoidal pure sine wave output of this unit delivers smooth utility-grade AC power across both split phase output legs — the low frequency transformer architecture maintaining waveform integrity under all load conditions from light resistive loads to heavy inductive motor loads. The sinusoidal waveform is particularly critical for:

• Variable Speed Drives — VFDs and variable speed appliances requiring precise frequency and voltage control
• Audio Equipment — high-fidelity audio systems sensitive to harmonic distortion in the AC supply
• Medical Devices — CPAP machines and other medical equipment requiring utility-grade sinusoidal power
• Precision Instruments — test and measurement equipment sensitive to power quality variations

Split Phase 220V Panel Applications

The 24v pure sine wave inverter split phase output produces two legs of 110V AC — totalling 220/240V between legs — enabling direct connection to standard North American 220V residential and commercial main panels. This architecture powers the complete range of 240V loads — well pumps HVAC units electric water heaters ovens and industrial equipment — simultaneously with all 120V household loads from a single inverter unit without external phase conversion.
