Product Description

big power 50KW, 80KW, 100KW,120KW, 150KW,200KW off grid inverter

Sandi big power 50kw, 80kw, 100kw, 120kw, 150kw, 200kw off grid inverter approved by UL1741 & CSA22.2 standard. The output voltage, phase and frequency can be customized. It can make split phase 120/240VAC or 3 phase 120/208VAC 60Hz output. Inverter can add AC bypass input switch, built in battery charger, RS485 monitoring optional. 


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 

Unique functions

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 

Complete Protection
