Product Description

 Product Feature
1, Using the sixth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function for short circuit, over load and over temperature which is more safe and reliable. It's service life can up to 15 years or more.
2, Intelligentized, modularized and simple structure design, very easy and convenient for maintenance.
3,Two kinds of start mode: Step Down Voltage Start and Variable Frequency Start. Customer can set start mode according to the type of their load. This function is very convenient for users and also reduce frequency converter's usage, save more cost and easy to connect wires and control.
The output frequency 50Hz/60Hz can be set via LCD panel.
4, The output voltage can be set between -40 % to +20 % of rated voltage. And the accuracy of output voltage is very high less than 1%.
5, The DC input voltage range can be set. over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point and under voltage recovery time all can be set via the LCD panel. Convenient for increasing or reducing the quantity of batteries and solar panel in the future.
6, Using SVPWM space vector algorithms, high conversion efficiency, high instantaneous power and low losses, higher efficiency > 94%.
7, Pure sine wave output. with good transient response less than 50MS, little harmonic distortion, higher conversion efficiency and stable output voltage.
8, Low frequency transformer, which ensure the AC busbar and DC busbar are completely isolated to avoid interference, high efficiency and very little no-load loss.
9, Powerful data display and fault instruction function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.
10, Wide input voltage can be set according to customer's requirement. Input voltage range can be selected from 100-300V or 200-500V or 500-850V. This wide voltage input off grid inverter can work without battery and solar charge controller, which save battery cost and same like with MPPT function can maximum make full use of solar power.
11, AC bypass input function optional: Battery Power Priority or AC Bypass Priority work mode can be set.
