FORCE CHARGE

The force charge commands are used to force the solar controller into either bulk charging or float charging. This can be done on both the GP-RVC-MPPT-10 and the GP-RVC-MPPT-30. On the GP-RVC-MPPT-30 the force charge commands give the option to force charge either battery so, for example, if Bat1 is connected to the house battery and Bat2 is connected to the starter battery and both batteries are low the force charge command can be used to force the charger into charging Bat2 instead of it’s usual priority, Bat1.

If the battery voltage is below the bulk-absorption voltage and the force to bulk command is issued the controller will enter a bulk charge state and provide maximum current to the battery bank according to the charging current limit setpoint. Regardless of the state of the other battery (if using GP-RVC-MPPT-30) the controller will continue to bulk charge this battery until the bulkabsorptoin setpoint is reached, then it will enter it’s normal priority sequence. If the battery voltage is higher than the float voltage and the force to float command is executed the controller will enter a float charge stage and allow the voltage to lower to the float voltage setpoint. This command is used to cancel an absorption charge early, so the normal priority sequence is still followed. Thus, if Bat1 ever goes below the recharge voltage setpoint the controller will still switch to Bat1 and start bulk charging.

The force charge command can also be cancelled by choosing the “Normal” option, which will cause the controller to go back to it’s regular priority sequence.

The force charge commands are found in the settings menu and is executed by scrolling to the line that says “Force CHG” and pressing the [ENTER] button. The [UP] and [DOWN] arrows can then be used to select the desired force charge command before executing the command using the [ENTER] button.

REST TO DEFAULTS

The reset to default command is used to reset all configurable parameters on the solar controller to factory defaults. This command is found in the settings menu and is executed by scrolling to the line that says [ Set Defaults ] and pressing the [ENTER] button.
