  • ★ This LFP Series Pure Sine Wave Inverter is a combination of an inverter, battery charger and AC auto-transfer switch. Low frequency, low Idle Current, BTS cable, remote control. It is UL1741 standard.

  • ★ The split-phase 4000 watts inverter requires 240VAC input and can provide 120VAC or 240VAC output power for all kinds of appliances, and it can output 50 or 60Hz via the SW4.
  • ★ AC/Battery Priority: Our inverter is designed with AC priority by default, you can choose the battery priority by SW5 switch.

  • ★ Adjustable Charging Current: The max charge current can be adjusted from 0%-100% via a liner switch. 

  • ★ Auto Gen Start: The battery power inverters can start up a generator when battery voltage goes low, and turn the generator off after battery charging is finished.

The SunGoldPower LFP 4000 Watt DC 48V AC 120/240 Split Phase Inverter Charger is a top high quality low frequency power inverter, built for running your whole house (small home), Business, RV System, Trailer or Boat Application, this inverter charger is perfect for your off grid system or an emergency backup supply.

The split-phase inverter requires 240VAC input and will output 110/120 or 220/230/240VAC, and it can output 50 or 60Hz via the SW4. It is capable of producing 2 legs of 110V, making this inverter perfect for home and business applications with a 220 panel in place.

Three in one product:
★ The inverter transforms 48V DC power stored by batteries to AC electricity that can power the tools and appliances.
★ It has a built-in 40 amp battery charger which help the grid or generator to recharge the battery.
★ The transfer switch allows the product to automatically switch between shore power and battery power within 10 mili seconds.

Frequently Questions Answer

1. What's the AC output amps?

Dear Customer, output amps is 16A, load can't exceed 4000W when 240V AC load, load can't exceed 2000W when 120V AC load, because this is split phase inverter, the power will be divided to 2*2000W when 120V output, hope your kind understanding, thanks.

2. What is the maximum charging voltage for this Inverter?

Dear Customer, it will have over charge protection shutdown if it exceeds 62.8V, thanks.

3. Can it charge 7 modules of Nissan leaf battery? (56 volts 66ah) (1 module: 8v 66ah)?

Dear Customer, you could find the battery type selector in manual, you need to choose different switch position according to your battery voltage, please download manual from Technical specification of product page, in addition, the battery total voltage can't exceed 48V, thanks.
