Overview

15kW sine pure wave power inverter is a 3 phase off grid inverter with no battery for the solar system, converts the DC power to AC power, it is useful for areas without electricity, vehicles, ships, solar energy and other renewable energy systems, etc.

Features

  • 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.

Tips: Off-grid solar inverter display overload or unable to be started, how to solve?

Fault analysis: The load power is greater than the inverter or battery power.

Possible reason:

  1. Inverter overload: If the inverter overload exceeds the time scope, the load power exceeds the maximum value, please adjust the load.
  2. Battery overload: The discharge current is generally 0.2C-0.3C, and the maximum value does not exceed 0.5C. As to one 12V200AH lead-acid battery, the output maximum power does not exceed 2400W. As to the batteries of different manufacturers and different models, the specific values are also different.
  3. The load is a load such as an elevator that cannot be directly connected to the output terminal of the inverter. Because when the elevator is descending, the motor reverses, and a back electromotive force is generated. In entering the inverter, the inverter is damaged. If an off-grid system must be used, it is recommended to add a frequency converter between the inverter and the elevator motor.
  4. The inductive load start-up power is too high.

Solution: The rated power of the load must be lower than the power of the inverter power, and the peak power of the load cannot be greater than 1.5 times the rated power of the inverter.

The best solar inverter!
To be honnest, I bought several pure sine wave off grid solar inverters here. They are super great so that I bought them again and again because my work really needs so many inverters. I highly recommend them!
