Connecting PV Production Meter
The PV production meter, which the storage
unit uses to determine how much renewable
AC power is available, is located inside the main
cabinet on the vertical main DIN rail. The current
transformers must be installed on the L1 and L2
outputs of the PV inverter.
1. Current transformers
▶
Mount the current transformers in a location
with access to L1 and L2, no more than three
meters away from the storage unit.
2. Connect current-measuring wires
The current-measuring wires are connected by
one end to terminal blocks on the main vertical
DIN rail. They are labeled on the unattached end
as follows:
• L1 CT S1
• L1 CT S2
• L2 CT S1
• L2 CT S2
Remove any wire ties or other attachments and
run them out of the top of the unit.

▶
Run L1 through current transformer 1
The side of the current transformer with P1 and
K must face the PV inverter. The side with L and
P2 must face the distribution panel.
▶
Connect the current transformer to the meter
▶
Connect the wire labeled "L1 CT S1" to the
S1 connection on the top of the L1 current
transformer.
▶
Connect the wire labeled "L1 CT S2" to the
S2 connection on the top of the L1 current
transformer.

▶
Run L2 through current transformer 2
The side of the current transformer with P1 and
K must face the PV inverter. The side with L and P2
must face the distribution panel.
▶
Connect the current transformer to the meter.
▶
Connect the wire labeled "L2 CT S1" to the
S1 connection on the top of the L2 current
transformer.
▶
Connect the wire labeled "L2 CT S2" to the
S2 connection on the top of the L2 current
transformer.
