Product Description

Product Description

 

VEICHI SIS series off-grid inverter is suitable for the household photovoltaic energy storage system. DC power generated by solar panels is stored in the battery through the inverter. When electricity is needed, it is first supplied by solar panels. If the light intensity cannot support the operation of solar panels, the inverter will convert the DC power of the battery into a three-phase power for home load. If the battery power is not enough, it can be quickly switched to power grid to supply power. 

SIS series off-grid inverter has a detachable LCD control module and a variety of communication functions. It can be remotely operated through the mobile phone APP, which is convenient and fast. It can output pure sine wave, run stable and reliable. Replaceable fan design enables customers to maintain safety and convenience.
