AC Module System Installation Manual

Rev. 1.0

The three phases need to be balanced, so it is recommended to use three arrays with an equal number of AC modules in
the array in each phase. Here is an example for AC output cables connected to three phase 208VAC below.

Step 1. Check your distribution panel to figure out what type of AC distribution system you have. Use a volt-meter to find out the phase

and line-to-line voltage across L1, L2 and neutral. If the AC distribution system has 208VAC for L1-L2 and 120VAC for L1-N

and L2-N, the AC modules should not be connected more than 18 AC modules for the three phase system having one 3-pole

20AMP circuit breaker at the distribution panel. And do not exceed 6 AC modules per phase.

Step 2. Install an AC junction box in an appropriate position for a transition cable to reach to the last AC module. If necessary, move the

AC junction box close to the last AC modules.

Step 3. Check extension/transition cables to verify they have not been pulled too tight or are hanging too loose. Attach cables on a

structure like PV racks or rails using the cable clips. Also, place extension/transition cables or AC cables under a structure so that

wires can avoid direct sunlight exposure and water immersion.

Step 4. Connect the equipment’s grounding conductor from all of the AC modules to the AC junction box by connecting to the distribution

panel.

Step 5. Make sure that a conduit protects wires from the AC junction box to the distribution panel from rain, snow or direct sunlight.
