- Wide MPPT window from 80 VDC to 450 VDC
- Bypass function prevents backflow when running on grid
Description
The LK-H6 runs on a 360 V DC bus, which keeps DC current low for a given power level and allows thinner battery cabling than a 48 V platform. Two ratings are offered: 6 kW with a single MPPT, and 12 kW with two.
A bypass function prevents backflow when the unit is running on grid, and the working mode can be set to grid, off-grid or hybrid. Charging priority and output priority are both configurable, and the inverter supports lithium BMS communication as well as operation without a battery - useful during commissioning or where the battery arrives later.
