Solar charger inverter for isolated installations of 11000W at 48V single-phase to be able to connect bank of solar batteries of the corresponding voltage (48V). The 11000W Axpert MAX has two MPPT's (maximum power tracking point) and provides a performance of 93.0%. The maximum input current of the solar regulator is 150A per MPPT.

The Axpert MAX II 11000W 48V can support up to 11000 Wp of solar panel power.


This gives a great advantage to be able to distribute any type of solar panels that we connect to it in an efficient and versatile way.


Axpert MAX-II 11K MPPT inverter and Pylontech lithium

This Voltronic solar hybrid inverter is capable of working with Pylontech and WECO lithium batteries thanks to its integrated RS485 communications port and already has a specific protocol for Pylontech and Dyness incorporated. You just have to select the correct parameter in the specific menu and choose the type of lithium solar battery being used. In this way we always ensure a correct charge and discharge of the battery, since it constantly informs the Voltronic Axpert MAX-II solar inverter of the status of the solar lithium battery and adjusts at all times to the needs of the lithium battery.


Use and applications Hybrid inverter Axpert MAX-II 48V 11000W PF1 2 X MPPT 150A

This 48V Voltronic Axpert MAX-II solar inverter is especially suitable for medium-sized installations such as country houses and second homes such as medium/high consumption habitual residences. All this thanks to the ability to connect up to 6 units in parallel, which allows us a total power of up to 66kW. This can be done thanks to a communications card that is already integrated as standard within the solar inverter itself. Thanks to its great instantaneous overload potential, we are able to start very heavy loads such as compressors or large motors, always in line with the power of the Voltronic MAX-II inverter.
