Description
The LK-L5 produces a split-phase output from a single chassis: 110 VAC from either leg to neutral, and 220 VAC leg to leg. That is what a North American panel expects, and it removes the need for a separate step-up transformer in a residential install.
Seven models cover 1 kW to 6 kW on 12, 24 or 48 V batteries. The toroidal transformer gives > 85% conversion efficiency and a 4 ms transfer time, and the charger accepts a wide 70-275 VAC input so it can work from a generator as well as the grid. Three working modes - mains priority, inverter priority and energy-saving - are selectable.
