Description
The LK-L4 ships with two displays: one built into the chassis and a second, detachable panel that can be mounted remotely. On a vehicle, a boat or a cabinet installation, that second display is often the only way to read status without opening the enclosure.
Eleven models cover 1 kW to 12 kW across 12 / 24 / 48 V batteries. The low-frequency stage handles 3x surge, mains charging current is adjustable from 0 to 30 A, and an optional built-in MPPT controller can be specified. Generator input is supported across the range.
Product highlights
- Eleven models from 1 kW to 12 kW
- Internal plus detachable external LCD with adjustable brightness
- Microprocessor control for faster, more accurate regulation
- Adjustable mains charging current, 0 to 30 A
- Generator compatible, 3x surge capability
- Optional built-in PWM or MPPT solar controller
