RCT Axpert King MK2 5kW
RCT-AXPERT KING MK2 5K48V · RCT (Voltronic Power)
Off-grid, single-phase
Good to know
- Works with panels and a battery; the grid or a generator can top it up, but it doesn't feed power back to the grid.
- Output 5000 W (5000 VA).
- Takes up to 6000 W of panels (up to 500 V, – MPPT inputs).
- Battery: 48 V (40-66 V), charging up to 100 A.
- Switches to backup in 0 ms (the datasheet's UPS / transfer time).
- Warranty: Not stated on the datasheet.
