Steca AJ
Inverters with different DC input voltages and a variety of power classes
Description
The Steca AJ inverter series is characterised above all by the variety of available power classes and different DC input voltages it offers.
This means that the ideal inverter can be selected for every application. The cables for connecting the battery and the loads are already pre-assembled on the Steca AJ and help facilitate the device installation. The automatic standby mode significantly reduces the inverter's self-consumption. The excellent overload capacity of the Steca AJ inverters ensures that even critical loads can be operated without any problems.
