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
Single phase 240V (per 1-array)
Three phase 208V
(per 3-array)
* 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.
Number of Maximum AC Modules
12 units
6 units ⅹ 3 (merge type)
11units ⅹ 3 (split type)
20A Circuit Breaker
2-pole ⅹ 1ea
3-pole ⅹ 1ea
2-pole ⅹ 3ea
After receiving the product, inspect all parts for possible deformity or malfunction.
