🗺️ Electrical Topology & Working Modes
Electrical Topology
Dual MPPT PV inputs + Li-ion battery input connected to DC bus via bidirectional DCDC. 3-phase full-bridge inverter on the rear. AC side integrates grid breaker, off-grid switch and genset terminal. Built-in EMS for coordinated control of PV, battery, grid and diesel genset.
3 Operating Modes
- Grid-tie Self-use: PV powers loads first, excess to grid, shortage from grid; battery peak shaving;
- Off-grid Island Mode: Auto switch to off-grid when power failure; PV+battery+genset supply power;
- Hybrid Genset Mode: Genset starts automatically when PV/battery is insufficient.
