300-500vdc input rack mount off grid inverter

Product Introduction:

Our DNP series Low Frequency Off Grid Pure Sine Wave Inverter(300-500vdc input rack mount off grid inverter) is the one of the most advanced technology DC to AC conversion products in the world. Output pure sine wave, perfect protection function of overload, short circuit, low/over battery voltage, over temperature etc, AC output power is suitable for all kinds of AC electric equipment, such as air conditioners, electric motors, refrigerators, lights, televisions, electric fans and other industrial power supply. Our inverter is widely used in solar power systems, wind power systems, wind and solar hybrid systems. 

 

Technical Features/Our Advantages:

1. With low frequency transformer, 100% full power output, can work 24h*7. 

2. High efficiency > 94%, low loss and long service life > 15 years. 

3. Mitsubishi IPM intelligent modular structure design, easy and low cost for future's maintenance, powerful protection for over load, short circuit, over temperature which is more safe and reliable. 

4. The DC input voltge range, output voltage, output frequency can be set. 

5. Two kinds of start mode: variable frequency start or step down voltage start, higher capacity to drive inductive load. 

6. AC bypass input(DC power priority or AC bypass power priority can be set) and RS485 monitoring optional.

7. Wide voltage input range can be selected from 100-400VDC or 200-600VDC or 400-800VDC, off grid inverter can work without battery.

8. Powerful data display 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.

9. Approved by European CE (EMC, LVD, UL1741, CSA22.2) certificate.

10. 1KW-20KW rack mount inverter optional, 1kw-500kw stand cabinet inverter optional.
