Description
The LK-H4 places the control and display panel on the lower front face instead of the centre, which keeps the operating buttons reachable when the unit is mounted at eye level or stacked under a distribution board. The range runs from 3.3 kW to 12.3 kW.
Electrically it matches the rest of the dual-output hybrid family: 24 V or 48 V battery bus, up to two MPPTs, 94% peak efficiency and a 10 ms transfer time. Grid-tied, off-grid and hybrid modes are selectable from the panel, and the second AC output can be configured to drop non-critical loads automatically.
Product highlights
- Seven models from 3.3 kW to 12.3 kW, single phase 230 V
- Front-mounted control and display panel for easy access
- Second AC output rated at 30% of main output
- Up to 2 MPPTs, 500 VDC maximum PV open-circuit voltage
- 94% peak efficiency, 10 ms transfer time
- Lithium BMS communication and battery-less operation
