1PV module

Converts the solar energy to DC power.

2Micro inverter

Converts DC power generated by each PV module to AC power.

3PV frame

Protects and fixates AC module.

4AC drop cable

Connects a micro inverter to trunk cable.

5Trunk male connector

Junction connector between AC drop cable and trunk female connector.

6Trunk female connector

Connects to trunk male connector of the next AC module in the array.

7Bracket

Fixes trunk cable onto PV frame.

8Dust cover

Prevents entry of foreign particles.

9Cable holder

Prevents AC trunk cables from moving during transportation.

※ Warranty is void if it is broken after installed.

3-4 Measuring AC Voltage of the Utility

Measure the AC voltage of the utility at the distribution panel using a multi-meter. Refer to the table below to determine the number of modules per array.

AC Voltage	Number of Maximum AC Modules	20A Circuit Breaker
Single phase 240V (per 1-array)	12 units	2-pole ⅹ 1ea
Three phase 208V	6 units ⅹ 3 (merge type)	3-pole ⅹ 1ea
(per 3-array)
	11units ⅹ 3 (split type)	2-pole ⅹ 3ea

* For details, refer to Chapter 3-10. Connecting AC Module Array to the Distribution Panel.

* Factory setting of AC voltage of the AC modules is 240VAC. If you want to change the operating AC voltage range, you need to set grid configuration directly. For details, refer to Chapter 4-3. Configuring the Installation App - Step 5.
