* 3 phase off grid inverter 20KW solar inverter
Sandi 3 phase off grid inverter 20kw solar inverter is one of the most advanced DC to AC conversion products in the world. It has the main advantages of high quality pure sine wave AC output, high efficiency, low no-load loss, long service life, little fault rate, 100% full power output, humanness design, modular structure easy for maintenance and no pollution.
Easiest and Economical After-sale Repair
1.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, non-professionals also can operate
2.Low maintenance cost, one complete set of maintenance parts not more than 300USD, save more time,energy and cost in the future
3.Little fault rate < 1%
4.Fault alarm code display, can remote guide customers repair
1. Battery power priority or AC bypass priority can be set
2. 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.
3. The output frequency 50Hz/60Hz can be set.
4. The output voltage can be set.
5. Variable Frequency Start or Step Down Voltage Start
powerful complete protection function for under voltage, over voltage, over current, short circuit, over load and over temperature which is more safe and reliable.
