Effekta AX-K1 Series Manual

AX-K1 Series Multifunction Inverter/PV Charger

Overview

The AX K1 series with an integrated MPPT solar charge controller are multi-function inverters/PV chargers that combine the functions of an inverter and a solar/battery charging device. Suitable for standalone operation independent of the mains supply, these inverters can also be powered by accumulators, generators, or the public power grid. In cases of insufficient PV power, the device supplements power with battery current or switches to the mains power grid if the batteries are fully discharged. Up to three AX units can be configured for 3-phase operation.
