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.
