Kit contents
- 10 x 450W all-black TOPCon panels
- 3.6kW single-phase hybrid inverter
- 5kWh LiFePO4 low-voltage battery
- PV cable
- MC4 connectors
- Roof mounting system
Key features
High-efficiency N-type TOPCon panels with module efficiency of up to 23.35%, placing them in the upper tier of solar modules currently available. Higher efficiency means more electricity from the same roof area, which is valuable where roof space is limited.
- Total PV array 4.5kWp
- All-black N-type TOPCon bifacial dual-glass panels
- Hybrid inverter with battery backup (UPS switchover under 10ms)
- 5.22kWh LiFePO4 battery, 90% depth of discharge, over 6000 cycles
- Expandable up to 8 batteries in parallel
- IP65 inverter and battery
- AFCI arc-fault protection and rapid shutdown
- Wi-Fi/4G monitoring
