Automatic Equalization
The C-Series controller can automatically trigger an
equalization charge every 30 days. The status LED will
indicate that the equalization process is occurring.
The equalization process will continue until the voltage has
been held above the bulk setting for a cumulative period of
two hours. This might take several days on larger systems
with big batteries and small PV arrays. The battery voltage
only needs to exceed the bulk setting for the timer to start
counting–the voltage may not reach the equalization voltage
setting.
To enable automatic equalization, the jumper located on the
right side of the circuit board must be moved to the A
UTO
setting. The default setting of the C-Series controller is for
manual equalization. To disable the automatic equalization
system, move the equalize jumper to MANUAL.
Once a manual equalization has been triggered, the 30-day
period to the next automatic equalization will be restarted. To
prevent automatic equalization, move the equalize jumper to
the manual position.
