Blue LED “bulk”: will be on when battery has been connected
Switch off when the absorption voltage is reached.
Blue LED “absorption”: will be on when the absorption voltage is reached.
Switches off at the end of the absorption period.
Blue LED “float”: will be on after the solar charger has switched to float.
8.1 Outstanding conversion efficiency
