Description
The LK-H1 is a wall-mounted single-phase hybrid inverter family covering 1 kW to 12.3 kW in twelve steps. It combines a high-frequency inverter, a wide-range MPPT solar charger and a multi-stage mains charger in one enclosure, so a single unit can run a load, charge a battery bank and export surplus solar to the grid.
The platform accepts lead-acid, gel and lithium packs on a 24 V or 48 V bus. A full digital control stage allows bidirectional energy flow, which means solar and mains can charge the battery at the same time while the inverter feeds the load. Nine working parameters - including grid-current limit, output priority and charge priority - are set from the front panel or over RS485, so the same hardware can be configured for grid-tied, off-grid or hybrid duty.
Product highlights
