Operating Modes
The DC controller is a critical component in any solar, wind
or hydro power generation system and protects the batteries
from over-discharge and over-charge conditions. The
C-Series has two operating modes (Charge Control mode and
Load Control mode determined by the Operating mode
jumper (See Figure 2-5). These two different operating
modes allow the C-Series to be installed and function as three
different DC controllers.
• Charge Control Mode
• PV Charge Controller - controls charging in PV
installations.
• Diversion Controller – used in PV, wind, or hydro
installations to divert any excess energy to a diversion
load and in the case of a wind or hydro generator, helps
to prevent over-spin damage.
• Load Control Mode
• Load Controller - prevents damage to the battery from
over-discharge during periods of poor charging or
excessive loads.
