12. Connection of the RS-485 communication for external
wattmeter
In self consumption installations, the use of an external wattmeter at the connection point with the distribution
grid allows the inverter to have control over all the existing loads, both critical and non-critical.
This chapter explains the requirements and process for connecting the RS-485 communication wiring to the
external wattmeter. Read carefully before starting the connection process.
INFO
For more information about compatible wattmeters, see the "List of compatible wattmeters for with
INGECON SUN STORAGE 1Play TL M", available on the Ingeteam website. If the required wattmeter is not in
the list, contact Ingeteam.
12.1. Safety instructions for connecting the RS-485 communication
for the external wattmeter
CAUTION
Before you start to make the connections, make sure there is no voltage in the inverter. Check that the
protections for the grid/genset, critical loads, storage system and PV array are open.
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.
