Features

Two kinds of start mode: 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 rated voltage. And the output voltage is very accuracy ±1%.
Pure sine wave output. With good dynamic response less than 50MS, waveform distortion rate smaller, 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, 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:

The conversion efficiency of photovoltaic solar off grid inverters refers to the efficiency of the inverters in converting the electricity from solar panels into electricity. Solar inverters play the role of converting direct current from solar panels into alternating current, and transmitting these alternating currents to the power grid. If the off grid inverters' conversion efficiency is high, the power supply for the use of the inverters will be increased.

Inverter efficiency has two major determinants. First, when converting DC current into AC sinusoidal wave, it is necessary to use power semiconductor circuit to switch DC current (very short time on and off). At this time, power semiconductor will heat up, resulting in loss. By improving the design of switch circuit, this loss can be minimized. Another factor is to improve the efficiency by relying on the control performance of the solar inverter. The output current and voltage of solar panel will change with sunshine and temperature at any time. Solar off grid inverter can control the current and voltage optimally to achieve the maximum power (power point). The shorter the time to find the best power point, the higher the conversion efficiency will be.
