Connecting The Energy Meter - SMA SUNNY BOY 3.8-US Instructions D'installation

6 Electrical Connection
9. Connect the conductors of the communication
cables to a 6-pole terminal block. Pay attention to
the assignment of the terminal block and
communication connection on the battery and/or
automatic transfer switch and make sure that CAN L
and CAN H consist of a pair of conductors.
10. Make sure that the conductors are plugged into the terminal points tightly by pulling slightly on
the conductors.
11. Insert the terminal block for the communication
connection into the jack BATx on the battery
interface module. If only one battery is available,
insert the plug into the jack BAT1. If multiple
batteries and/or an automatic transfer switch are
available, insert the communication connection of
the first battery into the jack BAT1 and connect all
other communication cables in succession to the
respective jacks.
12. Press the communication cable with cable shield into
the shield clamp on the busbar below the
communication assembly.

Connecting the energy meter

This section describes the connection of the energy meter to the inverter.
The energy meter measures the flow of energy out of and into the utility grid. The measured values
of the energy meter are transmitted to the inverter and influence the charging behavior of the
battery. Along with the energy meter, two electrical current strength transducers must be installed
between the grid-connection point and the feed-in point of the battery inverter and the PV system.
The energy meter and the electrical current strength transducers can also be mounted in the
automatic transfer switch in battery-backup systems. Please observe all manufacturer specifications
and safety notices when installing the energy meter. The energy meter is not a replacement for a
revenue grade meter (RGM). The energy meter data may not be used for billing purposes.
