BD 3-10kW Off and On-grid Integration

BD 3-10kW Off and On-grid Integration
iMars BD series off-grid/grid-connection integrated machine is based on the concept of intelligence and maintenance-free theory. The product integrates charge, energy and photovoltaic inverter, the BMS battery management system and other functions into one. It can automatically judge the off grid / grid connection mode, and connect to the smart grid, thereby realizing the power consumption requirements such as peak shaving and valley filling, self-generation and self-use, etc..
