In basic application, a converter-charger combines the functions of inverter, battery charger, transfer system and source assistance. These functions can be combined and managed completely automatically for ease of use and optimal management of the energy available. Programmable auxiliary contacts also allow interconnection with existing systems or the realization of extended functions.

In the event of disconnection from the dock or a group, a converter-charger takes over powering the connected loads. This transfer is so fast that the operation of computers or sensitive electronic equipment will not be disrupted.
