Description
The LK-H2 adds a second AC output to the standard hybrid platform. The main output carries priority loads, while the second output can be shed automatically when battery state of charge or PV input falls below the configured threshold - useful where a site must keep refrigeration or lighting running but can afford to drop air conditioning.
Models run from 3.3 kW to 12.3 kW on a 24 V or 48 V battery bus, with up to two MPPTs on the larger units. The second output is rated at 30% of the main output. As with the rest of the range, grid-tied, off-grid and hybrid modes are selectable, and the unit supports lithium BMS communication and battery-less operation.
