Description
The LK-L2 covers 1.5 kW to 12 kW in nine models, all wall mounted and all using a toroidal transformer. The low-frequency stage tolerates 3x rated power for short surges, which is what lets a 3 kW unit start a borehole pump or an air compressor that a high-frequency inverter of the same rating would trip on.
Battery voltage follows the model: 12 / 24 / 48 V on the small units, 24 / 48 V in the middle, and 48 V from 5 kW up. Mains charging current is adjustable so the charger can be matched to the battery bank rather than the inverter. An optional MPPT controller can be built in at order.
