25kw 3 phase 380-440V off grid inverter with ac bypass input grid as backup
Low Frequency Off Grid Inverter Advantages
Easy to repair
Difficult to repair
*Adopted Japanese Mitsubishi IPM intelligent module, Modular and simple structure design, very easy and convenient for maintenance, any fault only need us send you parts for replacement, maintenance is low-skill work
Used Mosfet Tube or little IGBT, integrated and complicated structure design, very difficult for maintenance, need send product back to factory for repair,
WASTE TIME AND WASTE MONEY
Little fault rate
High fault rate
It with powerful protection function for short circuit, over load and over temperature which is more safe and reliable.
Fault rate < 1%
100% full power stable output
Not full power output
Inside with full power low frequency isolated transformer, 100% full power output, can work 24h*7, which ensure the AC busbar and DC busbar are completely isolated, the harmonic and interference is very little, constant voltage and constant frequency stable output.
High frequency transformer, little capacity not full power inverter, 10KW inverter only can output 7-8KW, can’t take full load and run 24h/day
Long service life
Short service life
> 15 years
AC bypass input can be set
AC bypass can’t be set
City power priority or battery power priority can be set
Wide DC input voltage range can be set
*The DC input voltage range(over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point and under voltage recovery time) can be set, convenient for adding more solar panel or battery in the future.
The output frequency 50Hz/60Hz can be set.
Variable Frequency Start control motor speed.
The output voltage can be set.
And the accuracy of output voltage is very high less than 1%.
Two kinds of start mode
Variable Frequency Start or Step Down Voltage Start
with higher capacity to drive motor inductive load, normal inverter’s power need enlarge 3-7 times at least, however our inverter with VFD function, inverter’s power not need enlarge times, for example: 5KW inverter can take 3kw-5kw pump
Big LCD display
*LCD 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.
