5. My batteries drain very fast when the sun goes down The controller may read 100% while charging at the higher voltage, but it will quickly drop lower when no charge is applied. This could be because the batteries charge at a higher voltage, so when the sun goes down, the battery voltage will stabilise at a lower level.
