• Solar Priority Charging CSO
PV priority charging, whereby mains charging is only activated when the PV fails. By making full
use of the PV during the day and switching to utility charging at night, the battery power can be
maintained. This mode is suitable for applications in areas where the grid is relatively stable and
electricity is expensive. (Priority: PV > Utility)
• Only Solar Charging OSO
Only PV power is used to charge the battery, without starting the mains charging. This is the
most energy-efficient method, with all battery power coming from solar energy, and is usually
used in areas with good radiation conditions.
