Introduction
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.
