Off-grid PVI SMB series suit to battery

The DC OUT of PV charges the battery for energy storage with Sunfine SMB, when the produce energy of PV is in abundance, the DC OUT of PV will invert to stable AC supply to load with Sunfine SMB, and once the produce energy of PV is short of supplies and also the supply of national grid is abnormal, the DC OUT of battery will output stable AC supply to load.  Based on HF chain and parallel operation technology with DSP, several inverter can be parallel operated and run, simplified the design of the power station.  Adopted the IPM module of 5th generation of Mitsubishi, increasing the system efficiency greatly.  Self-optimizing of MPPT, increasing the efficiency of power produce of PV system.  Multi-battery polling and monitoring, assure the working life of battery.  Improved BUCK topology, realize the three-part charge management to battery.
