Description
The LK-L1 is a 1 kW low-frequency inverter built around a toroidal transformer. The transformer gives it a genuine surge margin and tolerates the distorted output of diesel and petrol generators, which is why this topology is still preferred for pumps, compressors and tools.
It accepts a 12 V or 24 V battery and delivers 220 VAC pure sine wave at ±2%. Mains charging current is adjustable, working mode can be set to mains priority or inverter priority, and an optional built-in MPPT controller can be specified at order.
