4) Solar energy: No strong enough
Priority mode: PV priority
AC power input: Normal
The system will convert the energy of battery and PV systems and give power supply to the user equipment.
If battery capacity less than 40%, AC input will provide power to equipments through regulator by relays and transformer. At this
time, PV gives power to batteries only through MPPT control system.
