Simple and Reliable
Exchanges energy via the electrical grid, no coupling with the PV inverter, mature technology, simple and reliable.
Can integrate with all grid-tied renewable systems, including solar, wind, fuel cell etc.
Easy installation
Compatible with existing grid-tied PV inverters.
No need to upgrade the distribution system.
Uses a split-core CT, no need to disconnect the electrical grid at all.
Multiple modes
Supports stand alone mode (like UPS), Ensures the safe operation of the critical load.
Programmable multiple operations modes: Grid tie, Off grid, and grid-tie with backup.
Flexible solution
Provides a full solution for energy consumers to maximize the use of their generated solar energy.
Increases self-consumption rate(from 20% to 70%).
User-adjustable battery charging current suits different types of batteries.
