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.
Product highlights
- Six models from 4.3 kW to 12.3 kW, single phase 230 V
- Detachable LCD control module for flexible installation
- Second AC output for intelligent load management
- Up to 2 MPPTs, 80-450 VDC tracking window on 48 V models
- 94% peak efficiency, 10 ms transfer time
- Lithium BMS communication, battery-less operation supported
