Diversion Loads

Diversion control requires a separate “dump” load to regulate 
the battery. This load must be able to absorb more power than 
the charging source is able to produce at its peak output, or 
the DC voltage will become unregulated. The dump load 
must be available for the diversion of power at all times.

Resistive-type heating elements are the best diversion loads. 
Special direct-current water heating elements are available. 
Light bulbs and motors are not recommended as diversion 
loads because they are unreliable. A diversion load that draws 
about 25% more current than the charging source’s maximum 
output capability is usually suitable for use with the 

C-Series 

controller

.

See 

Appendix C, “Diversion Loads”

 

for additional 

information on types of diversion loads.

See 

“Operating Mode Jumper” on page 20

 

for instructions on 

enabling this mode.
