12000W 48V Split Phase Pure Sine Wave Power Inverter


  • This Series Pure Sine Wave Inverter is a combination of an inverter, AC charger, Mppt solar charger and Auto-transfer switch into one complete system.It is packed with unique features and it is one of the most advanced inverter/chargers on the market today.
  • Our Low Frequency Inverter is designed with AC priority by default. This means, when an AC input is present, the battery will be charged first, and the inverter will transfer the input AC to power the load.The AC Priority and Battery Priority switch is SW4. When you choose battery priority, the inverter will invert from battery despite the AC input.
  • This inverter is equipped with a powerful charger for up to 120Amp (depending on Model).The overload capacity is 300% of the continuous output for up to 20 seconds to reliably support tools and equipment longer. The max charge current can be adjusted from 0%-100% via a liner switch on the right of the battery type selector.This will be helpful if you are using our powerful charger on a small capacity battery bank.
  • Features: Low Frequency Inverter, Smart Remote Control, Automatic Generator Starting (AGS), Support Solar Panel with MPPT Function. 8 pre Set Battery Type Selector, plus De-sulphation for Totally Flat Batteries. 4-step Intelligent Battery Charging, PFC (Power Factor Correction) for Charger. 8 ms Typical Transfer Time Between Utility & Battery, Guarantees Power Continuity. 15s Delay Before Transfer when AC Resumes, Protection for Load when Used with Generato.
  • Application: for all the kinds of load: circular saws, drills, grinders, sanders, buffers, weed and hedge trimmers, air compressors. Computers, printers, monitors, facsimile machines, scanners. Vacuum cleaners, fans, fluorescent and incandescent lights, shavers, sewing machines. Coffee makers, blenders, ice makers, toasters. Metal halide lamp, high- pressure sodium lamp.Television, VCRs, video games, stereos, musical instruments, satellite equipment etc.


Ask a Question
  • Can the Inverter/charger be configured for 120v AC input?

    hello, this item can not be connected with 120v input
    but we can customize the inverter with 120v input, it will take 30 days to produce it.

  • What is the max amps allowed as input from the solar array?

    hi, the solar input voltage is 60-100v,the max input current is 40a.

    Frequently Questions Answer

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

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

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

        Dear Customer, if you need have 240V & 120V load at the same time, HOT1 will have 2cables connected, but please note that 120V load power cannot exceed 50% of inverters real power, it is only 6000W if 120V output, hope your kind understanding, thanks.

    3. Can two units be connected together for 24 kW continuous?

        Dear Customer, sorry, it can't, thanks.
