enphase IQ Combiner 5C

Section C - Wiring
Wire the input from
the IQBatteries
1. Use copper conductors sized to meet local code requirements and
voltage drop/rise considerations.
2. Bring in the wires from the IQBatteries.
3. Connect the ground (green or green/yellow) to the ground bar.
4. Connect L1 and L2 (usually one black and one red) from the
IQBattery to the circuit breaker(s). Observe the L1 and L2 polarity
marking at each breaker position.
5. When installing both the PV and IQBattery on the IQCombiner,
it would be easier to install the PV on the lower breaker slots and
IQBattery on the upper breaker slots.
6. Torque all connections as indicated in the table on the previous
page.
7. For IQ8 grid-forming installations (i.e., with an IQ System Controller
3/3G), hold-down kits must be used for the breakers for IQ Battery
circuits as per the NEC code. The IQ Combiner 5/5C SKU's (X-IQ-
AM1-240-5-HDK and X-IQ-AM1-240-5C-HDK) come pre-installed
with the hold down kit.

NOTE: Do not pass conductors from IQBattery5P branch circuits
through the Production CT. This will distort production readings.
