8.4 Four panels in series-parallel (24V systems, 2x2 configuration)
Figure 8.6 Four RNG-100D Panels in series-parallel 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 MC4 Branch Connectors. When one or multiple panels are mounted at
different locations- that is, separated by a distance, the panels must be extended with MC4
Extension Cables (sold separately).
Note
This 24V array can only be used with a 24V battery configuration when
using a PWM Controller. Please do not use it with a 12V battery system.
