SunGoldPower 15000W 48V Split Phase Pure Sine Wave Solar Inverter Charger


  • LF-PV Series Pure Sine Wave Inverter is a combination of an inverter, AC charger, Mppt solar charger and Auto-transfer switch into one complete system.
  • The split-phase 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.
  • Features: Smart Remote Control, Automatic Generator Starting (AGS), Support Solar Panel with MPPT Function, Suitable for different kinds of batteries.
  • Application: for all the kinds of load: refrigerators, freezers, microwaves, dryers, air conditioners, pumps and all the big home and business applications.

SunGoldPower 15000W 48V split phase inverter is built for the purpose of running the whole house, business office or large RV, which is perfect for using with renewable solar and using as an off-grid home and business back up power supply. The split-phase inverter requires 240V AC input and can provide 110/120VAC OR 220/230/240VAC output power for all kinds of appliances.

This inverter charger is built with UPS function to provide uninterrupted power to run household electric devices. The solar inverter comes with an internal transfer switch, so you don’t have to do anything when the power goes out. All the devices you have selected will be connected to the back-up power source automatically. In fact, you will not even notice that the power cut happened.

  • It is built-in 100 amp battery charger uses AC power, from the grid or from a generator, to recharge different kinds of battery bank.   
  • Built-in solar controller, Maximum solar input voltage 145V, Maximum solar input current 80A, can also connect with external controller.
  • Low Frequency Inverter, High Quality, your best choice for your 48V home system.

This full sine wave power inverter was designed with top quality and durability in mind and is built to survive 10+ years in the harshest conditions . Our full sine wave 15KW inverter works with very little power loss, outputs an average THD of 3% , its idle consumption is 225 watts, and its peak DC to AC efficiency is notably 90%

The AC/battery priority switch is SW5. In AC priority mode, when utility AC power cuts off, the transfer relay is de-energized and the load is automatically transferred to the inverter output. Once the AC utility is restored, the relay is energized and the load is automatically transferred to AC utility. For solar systems, it is better to choose battery priority.

The Big Power Low Frequency Off Grid Solar Inverter is a multi-function inverter, combining functions of inverter, solar charger controller and battery charger to offer uninterruptible power support. the solar controller is Max 80A and 145V Input,You can disable the inbuilt solar controller, connect with external solar controller, or use for other systems (it is not limited for solar system)

The big power inverter has is the direct-connect terminal block, which allows users to surpass the 15,000 watt capacity and harness its 300% surge power (up to 45,000 watts for 20 seconds as previously noted). it is emergency backup power for residences, businesses and large off grid applications.

It is also perfect for off grid system or use AC power supply for home power emergencies, which can keep the power supply uninterrupted in the event of an power failure. It can detect the loss of power and switch over to get power form a connected battery bank seamlessly to keep the power supply constant.

Our Solar inverters are also instrumental when it comes to solar energy harvesting and increasing the system efficiency. When the solar panels produce electric energy, the electric current flows to the solar inverter. The inverter then converts the DC into AC. From the inverter, the AC energy is ready for use to power the various appliances.

Another popular application of this inverter is for RV and vehicle upfitting applications, such as powering lights and other appliances in an off-grid cabin. It also can provide electricity for a mobile business or mobile office, and running camping equipment. it is the best choice for your big power system.

Frequently Asked Questions

How do you connect this to a home with the multiple phase system?

  • It only has dual phase output, 120V and 240V, it can't work with the multiple phase system, thanks.

Does this unit work with lithium batteries? Is there an adjustable curve for charge discharge voltages?

  • It's ok to work with lithium battery, LiFePO4 in types is for lithium battery, in addition, we are sorry to advise the charge and discharge voltage can't be adjusted, hope your kind understanding, thanks.

Can two units be connected together for 24 kW continuous?

  • Sorry, it can't, thanks.

Looks good

I'm new to inverters so I don't know all the ins and outs technically, but I am an engineer so there are things I noticed. First, the unit seems really well built, it is heavy and feels very solid and that is a plus to me. I doubt I will ever push it to its limits but it feels like it could handle a lot. It also seems to have good customization and allows me to have options for how it is set up, what the priority it uses, how much charge is current, etc. I have kept tweaking things as I test it out. And I also really like the LCD screen and lights, always on giving me good info. I added other meters to supplement but they are not always on and the LCD is helpful. All and all I'm pleased looks like it will meet my needs for a long time
