🗺 Electrical Topology & Working Modes
System Topology Introduction
Dual independent MPPT PV input + wide-range lithium battery access connect shared DC bus via bidirectional DCDC converter. Rear-end adopts three-phase full-bridge inverter topology, AC terminal integrates grid breaker, off-grid load output & diesel genset access terminal. Built-in EMS core controller to realize automatic coordination among PV, battery, mains & diesel generator.
Three Standard Operation Modes
- Grid-tie Self-consumption:PV prioritizes local load consumption, surplus power feed into grid, battery charge during off-peak tariff for peak cut;
- Off-grid Island Mode:Auto switch off-grid within<5ms once utility blackout, PV+battery supply critical loads continuously;
- Diesel Hybrid Mode:Genset auto-start when PV & battery insufficient to cover load for long-time off-grid power supply.
