If the current from the PV array reaches 85 amps, the
controller will turn off to protect the circuitry. In the event of
a shutdown, the controller automatically resets itself after
10 minutes (if overcurrent condition is no longer present).
See “Operating Mode Jumper” on page 20 for information on
configuring this function.
Automatic PV Array Night Disconnect
When using PV Charge Control mode, the PV array is
automatically disconnected from the battery at night to
prevent reverse leakage of power. This eliminates the need
for a blocking diode between the battery and the PV array. If
thin-film or amorphous solar modules are being used, diodes
may still be required to prevent damage from partial shading
conditions.
Check the documentation provided with the PV modules.
Diversion Controller
The C-Series controller can operate as a Diversion Controller,
also called a shunt regulator, to manage battery charging from
alternative energy sources such as PV, wind or hydroelectric
generators. A diversion controller monitors battery voltage
and, when the voltage exceeds the settings for your charge
stage (whether bulk or float), the power is diverted from the
source (solar, wind, or hydro generator) to a “dump” load
which will dissipate the excess power into heat.
When used for this purpose, the C-Series controller varies an
amount of battery voltage to a “dump load” in order to
redirect the excess power generated from over-charging the
batteries. This allows the charging source to remain under
constant load to prevent an over-speed condition which could
occur if the charging source is suddenly disconnected from
the battery–as series regulators do.
Consult your dealer for recommendations on diversion load
type and regulator size.
