Multifunction inverter AX M2

The devices in the AX M2 series with integrated MPPT solar charge controller are 3000W / 5000W multifunction inverters / PVchargers with the combined functions of an inverter as well as a solar and battery charging device. These inverters are suitable for standalone operation in-dependent of mains supply via PV modules but can also be operated with electrical power from accumulators, generators or the public power supply grid.
If insuffi cient power is being supplied from the PV modu-les, the device automatically tops up the power level with battery current or, if the batteries are discharged comple-tely, it switches over to the mains power grid. A network of three AX units can be confi gured for 3-phase operation.
