The hybrid inverter Studer Xtender XTM Series is a typical representative of hybrid inverters. It is made in a number of variants according to the required output power and the voltage of the connected battery. A typical example is the XTM 2600-48, which has a continuous output power 2,000 VA, nominal voltage of the battery 48 V and an inverter with a high flow current at 50 A (from input to output).
The inverter is connected to the Foxtrot system via the RS-232 interface using the Xcom-232i communication module, which is connected with the inverter via the Com.Bus interface (equivalent to the CAN bus). Multiple inverters can be connected to the communication module, so it is possible to implement e.g. a three-phase assembly, inverters arranged in parallel, etc.

Notes:
-
In the Foxtrot system you can use any communication channel with the RS-232 interface, with max. cable length 15 m, with a recommended cable RS-232.
-
The cable of the Com.Bus interface can be up to 300 m long.
