Description
The LK-L3 is the widest low-frequency family in the programme: eighteen models from 700 W to 40 kW, spanning 12 V, 24 V, 48 V, 96 V, 192 V, 240 V and 384 V battery banks. That spread lets a single product family serve everything from a 700 W rural cabin to a 40 kW three-phase-site inverter without changing supplier.
Above 3.5 kW the units move to 48 V and higher buses, with MPPT input power scaling to 22.4 kW x2 on the 40 kW model. All models deliver pure sine wave at 220 / 230 / 240 VAC with > 85% conversion efficiency, and accept diesel or petrol generator input.
