12000W 48V Split Phase Pure Sine Wave Inverter Charger

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 12KW inverter works with very little power loss, outputs an average THD of 3% , its idle consumption is 180 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 Inverter is a multi-function inverter, combining functions of inverter, and battery charger to offer uninterruptible power support. 

The big power inverter has is the direct-connect terminal block, which allows users to surpass the 12,000 watt capacity and harness its 300% surge power (up to 36,000 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.

During the emergency situations, the inverter can become a true UPS (Uninterruptable Power Supply) with its seamless transition transfer switch (batteries required). It can convert DC to AC power cleanly and efficiently. It can also automatically charge a battery bank when the city or generator power is available. The switch goes back and forth between city/generator power and inverter power automatically.

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.

FAQ

1. 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.

2. This inverter can use 240v, and 120v at the same time?

    if you need to have 240V & 120V load at the same time, HOT1 will have 2cables connected, but please note that 120V load power cannot exceed 50% of the inverter's real power, it is only 6000W if 120V output.

3. What is the power consumption of the inverter with no load?

    the power saver on idle consumption is 40W and the power saver off idle power is 180W, thanks.
