12 V1.0.1 User Manual
4. Installation
The Xcom-MS constitutes the interface between the Xtender communication bus and the MorningStar MPPT
solar charge controller bus RS-485, as represented in figure 4.1. It is only possible to connect one Xcom-
MS to each Xtender bus and 1 to 30 solar charge controllers on the RS-485 bus. It is recommended to use
short RS-485 connections.
The solar charge controller TriStar MPPT-60 is equipped with a serial RS-485 port. The
TriStar MPPT-45 model needs the MorningStar RSC-1 accessory in order to connect
with the Xcom-MS.
Figure 4.1. Connection schematics of the Xcom-MS
The installation includes three steps. Start by connecting the Xcom-MS with the Xtender communication bus
according to the procedure explained in section 4.3. Secondly, assign one unique address to each solar
charge controller on the RS-485 bus. This is done by connecting each solar charge controller separately to the
Xcom-MS on the RS-485 bus. Using parameter {8002} the solar charge controller's identifier is set according
to the procedure in section 4.4. When all solar charge controllers have been given an address, connect them
to the RS-485 bus and the installation is finalized and ready to be used.
4.1. Mounting
The Xcom-MS can be mounted directly on any support by means of the supplied fixing plate or on a smooth
surface with a double-sided adhesive (see figure 3.2).
