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.
