Description
The LK-H7 is the 110 V variant, built for markets that run 105-120 VAC single phase rather than 230 V. Two models cover 3.3 kW on a 24 V battery and 6.3 kW on a 48 V battery, with one or two MPPTs respectively.
Grid input tolerance is 85-140 VAC, wide enough for weak rural feeders, and the AC output holds ±2% at 105, 110, 115 or 120 VAC. The unit offers the same three working modes, bypass function and lithium BMS support as the 230 V platform.
Product highlights
- 105 / 110 / 115 / 120 VAC output for North American and similar grids
- 3.3 kW on 24 V and 6.3 kW on 48 V battery banks
- 85-140 VAC grid input tolerance for weak feeders
- Wide MPPT window, 500 VDC maximum PV open-circuit voltage
- Bypass function prevents backflow when running on grid
- 92% peak efficiency, 10 ms transfer time
