This system generates 50Hz/60Hz with 230V AC generated from the Li-ion battery backup system. The capacity (rating) ranges from 800VA to 1800VA depending on the battery size and backup requirement. The product performance is managed and controlled by an intelligent battery management system (BMS). And, an LCD shows important inverter battery performance statistics helping customers plan their activities in advance.

System Benefits​:

  • A low-frequency and high-frequency inverter can be derived from the same system.
  • Isolated system to track the AC output.
  • Auxiliary flyback power supply for isolated systems.
  • RL78/G14 low-cost MCU performs the low and high-frequency H-Bridge drive.




  • Home inverter
  • General inverter
  • Battery Management System (BMS)
