8.4 Four panels in series-parallel (24V systems, 2x2 configuration)

For 24V systems,

Fig. 8.6.

Shows two strings of panels in parallel. Each string consists of two

panels in series. No additional cabling is required if the solar panels are to be mounted in a

2x2

configuration as shown above. Please note the orientation of the junction boxes. This

connection requires a

one (1)

pair of Solar Y Branch Connectors. When one or multiple panels

are mounted at different locations- that is, separated by a distance, the panels must be

extended with Solar Connector Extension Cables (sold separately).
