NOTE: The following rules MUST be obliged when setting custom parameters.
Rule 1: High Volt Disconnect > Charging limit voltage ≥ Equalization voltage ≥ Boost
voltage ≥ Float voltage > Boost return voltage;
Rule 2: High Volt Disconnect > Over Voltage Reconnect;
Rule 3: Charging Limit Voltage > Low voltage reconnect > Low voltage disconnect;
Rule 4: Charging Limit Voltage > Under voltage recover > under voltage warning;
Rule 5: Boost return voltage > Low voltage reconnect;
Charging Parameters Glossary
High Volt Disconnect—users can use the default parameters or assign a rated voltage value
that the charge controller will operate. When and if the charge controller experiences a voltage
higher than what is assigned, it will disconnect itself from the circuit; ceasing charge.
Charging Limit Voltage—depending on the batteries used, there might be a battery charging
limit voltage that is recommended for the battery. This parameter ensures that the charge
controller does not exceed the default or assigned rated charging limit voltage. This is usually
put into play to optimize and extend the life of the battery. Relatively speaking, the higher the
charging voltage then there is a correlation for reduced battery efficiency. (Likewise the lower
the discharge voltage affects battery efficiency.
Over-voltage Reconnect—In the event a charge controller experiences an over-voltage
condition set by the previous two parameters, then this reconnecting parameter is put into play
to direct the controller when it can connect and safely charge again. Typically over-voltage
reconnection is achieved when time has passed (ex. The sun setting), or when the over-voltage
condition is remedied ultimately reducing the voltage to a user defined charging voltage.
Equalization Voltage—equalization voltage is a corrective over-charge of the battery. The user
should consult their battery manufacturer regarding specific battery equalization capacity. This
parameter sets the equalization voltage to set the battery at when it reaches the equalization
state.
Boost Voltage—users should check with their battery manufacturer for proper charging
parameters. In this stage, users set the boost voltage where the battery will reach a voltage
level and remain there until the battery undergoes an absorption stage
Float Voltage—once the charge controller recognizes the set float voltage, it will commence
floating. The battery is supposed to be fully charged in his state, and the charge current is
reduced to maintain battery stability levels.
Boost Return Voltage—if at any point, the battery voltage levels registers to be below the
boost return voltage for an extended period amount of time, then the charge controller will
commence the boost stage once again.
