Charging Parameters Glossary
Overvoltage Disconnect—
When and if the charge controller experiences a voltage
higher than what is assigned, it will disconnect itself from the circuit; ceasing charge.
Overvoltage Recover--
in the event a charge controller experiences an over-voltage
condition set by the previous parameter, 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.
Undervoltage Recover--
deals with the loads connected to the system. When batteries
are determined to be low due to them approaching low voltage disconnect, then the loads
will be shut off to give the batteries time to recover. This parameter sets the controller to
shut off the loads until it can reach the low voltage reconnect stage.
Undervoltage Alarm--
this parameter deals with the batteries themselves approaching
the under-voltage recovery state. The user should minimize loads before the charge
controller approaches a level where it will do this automatically to protect the battery from
discharging.
Low Voltage Recover--
parameter allows loads connected to the system will be able to
operate (not fully) again.
Low-voltage disconnect--
prevents over-discharge of the batteries by automatically
disconnecting any loads. This extends battery life and is the precedent to being in an
under-voltage state, recovering from the undervoltage state, and finally reconnecting to
normal operational state.
