13. Connection of the CAN communication for Li-Ion
batteries with BMS
Installing the CAN communication enables the inverter to control the Li-Ion batteries with BMS (
Battery
Management System
).
This chapter explains the requirements and process for connecting the CAN communication wiring for Li-Ion
batteries with BMS to the unit. Read carefully before starting the connection process.
13.1. Safety instructions for connecting the CAN communication for
Li-Ion batteries with BMS
CAUTION
Before you start to make the connections, make sure there is no voltage in the inverter. Verify that the AC
protection of the auxiliary genset and the DC switch of the Li-Ion battery are open, as well as the PV array and
the consumption grid.
Do not switch on the power
to the unit until you have successfully made the rest of the connections and the unit
is closed.
When carrying out the connections, respect the polarities marked on the electronic card.
