6.3.1 Asymmetrical Loading for 10 TL, 15 TL, 20 TL, and 30 TL
The inverters operate using two separate MPP trackers that can handle both symmetrical and
asymmetrical loads to allow for optimum adjustment. This allows for the requirements of complex
PV system designs to be fullled. For example: east/west-facing roof (symmetrical load) or a
south facing roof such as a dormer (asymmetrical load).
See the following gures for explanation of how symmetrical and asymmetrical loading are
handled:
