Renogy 200W User Manual

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.
Low Voltage Reconnect—this parameter allows loads connected to the system will be able to
operate (not fully) again.
Under-voltage 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.
Under-voltage Warning—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 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 under voltage state, and finally reconnecting to normal
operational state.
Discharging limit Voltage—the user can set the “discharge” limit of a battery if they choose to
better protect the battery and expand its life. The following chart serves as an example of
voltages and their state of charges. Note that the higher the charging limit and lower the
discharge limit correlates with overall low battery life.
