Description
J1
Bus 1
CAN 1/CAN 2
These terminals are intended for future applications.
J2
Bus 2
PM 1/PM 2
This is the connection for the power flow direction sensor (PM
1) sowie and the connection for power flow direction sensor 2
(PM 2) in connection variant 2 (non-certified PV inverter).
J3
Bus 3
PV 1/PV 2
This is where the PV inverter is connected (PV 1 for PV inverter
1).
J4
Bus 4
COM 1/COM 2
This is where multiple SENEC storage units connected in
cascading operation are connected.
6.1.4 SENEC.Home Li connections
The electronics in the SENEC.Home Li communicate through the MCU with
•
the power flow direction sensor, and a further power flow direction sensor as necessary
•
the PV inverter, where certified
•
another SENEC storage unit in cascaded operation, where appropriate
•
a ripple control receiver, where appropriate
•
SENEC.Heat (compatible controlling power units), where appropriate
•
Internet router
•
Econamic Grid meter, where appropriate
