Description
The LK-H3 is the round-display variant of the dual-output hybrid platform, covering 4.3 kW to 12.3 kW. The LCD control module is detachable, so the display can be mounted on the front of the enclosure or relocated to a more accessible position when the inverter is installed in a tight cabinet.
Internally it shares the full hybrid feature set: two MPPT channels on the 8.3 kW models and above, a 24 V or 48 V battery bus, adjustable grid-feed current and three selectable working modes. The second AC output supports intelligent load management for sites that need to prioritise circuits during low-state-of-charge conditions.
