Description
The LK-S2 combines a toroidal low-frequency stage with a built-in MPPT controller and a split-phase output. Six models run from 3 kW to 12 kW on a 48 V battery, with a start capability of 3 HP to 7 HP for single-phase motors.
The MPPT input reaches 11.2 kW on the 8 kW and 10 kW models, and the AC charger is a three-stage constant-current, constant-voltage, floating-charge design. Output is 110 VAC or 120 VAC to neutral and 220 VAC or 240 VAC leg to leg, with max 4 ms transfer.
