IQBattery 5P metering for
grid-forming systems
For grid-forming systems, IQBattery 5P needs to be installed in the
IQSystemController 3/3G.
The IQBattery CT needs to be installed on the L2 line of the IQBattery with the arrow
pointing towards the battery lugs in the IQSystemController.
Risk of electrocution and equipment damage! Do not install CTs when
current is owing in the sensed circuit. Always install CT wires in the
terminal blocks before energizing the sensed circuit.
