Multifunction inverter AX M2 H

The devices in the AX M2 H series with integrated MPPT solar charge controller are 48V / 5000W multifunction inverters / PV-chargers with the combined functions of an inverter as well as a solar and battery charging device.

The AX M2 H version is designed for particularly high PV voltages of up to 500 V.

These inverters are suitable for standalone operation independent of mains supply via PV modules but can also be operated with electrical power from accumulators, generators or the public power supply grid.

If insufficient power is being supplied from the PV modules, the device automatically tops up the power level with battery current or, if the batteries are discharged completely, it switches over to the mains power grid. A network of three AX units can be configured for 3-phase operation.
