Battery is full
Once the battery is full the Multi RS will stop charging or will greatly reduce the charge current.
This is especially the case when at the same time the DC loads in the system are not consuming any power from the battery.
To find out what the state of charge (SoC) of the battery is, check the battery monitor (if present), or alternatively, check what charge stage the controller is in. Also, observe that the solar cycle is (briefly) progressing through these charge stages at the beginning of the daily charge cycle:
Bulk stage: 0-80% SoC.
Absorption stage 80-100% SoC.
Float or storage stage: 100% SoC.
Be aware that it can also be possible that the Multi RS thinks the battery is full, while in reality, the battery is not full. This can occur when the charge voltages have been set too low, causing the Multi RS to prematurely switch to the absorption or float stage. For more information see the Battery settings too low chapter.
