150kW Pure Sine Wave Off Grid Solar Inverter

150kW high power off grid inverter works at 50Hz/ 60Hz low frequency 3-phase 4-wire power system, pure sine wave output, no battery bank design, converting 240 volt, 300 volt DC to 400 volt, 480 volt (other desired voltages are customizable). Optional for AC bypass function and RS485 communication interface.
Delivery date: 6-12 days

Good pure sine wave off grid solar inverter is 150kW power capacity, digital LCD display data info, with AC bypass input, powerful protection function, safer and more reliable. It is designed to convert the DC power into AC power to power supply the AC load.


  • Two kinds of start modes: Step-down voltage start and variable frequency start. Customers can set start mode according to the type of their load.
  • The output voltage can be set between -40 % to +20 % of the rated voltage. And the output voltage with an accuracy ±1%.
  • Pure sine wave output. With a good dynamic response of less than 50MS, the waveform distortion rate is smaller, with higher conversion efficiency and stable output voltage.
  • Adopts black pure aluminum radiator, which confirms the best radiating performance.
  • Powerful data display function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, power consumption (kWH), time and date, temperature, and fault code display.
  • Wide input voltage can work without battery and solar charge controller, save more cost, and with MPPT wide voltage input function, maximum use of solar power.

PV Off-grid solar power generation system including solar panel array, solar charge controller, storage battery, Off-grid inverter, etc. In the sunshine, the solar panel converts the solar energy to DC power and charges the battery group by the charge controller. Then the off grid inverter converts the DC power into AC power to power supply the AC load.

  1. When there is sufficient solar or wind energy, the inverter is used to convert the solar or wind energy to the load directly.
  2. When there is insufficient solar or wind energy, the inverter will automatically supply solar or wind power to the load in conjunction with the AC grid or AC generator.
  3. Automatic regulating stable voltage and stable frequency output. Can set solar or wind power priority or AC grid or AC generator priority on LCD.

Works as advertised!
It really should have a high rating because this solar inverter works perfectly. Keep the manual handy; you will use it a lot! The system worked beautifully overall. I recommended my friends to buy one and they all thought it was great.
