Constant voltage and constant current (CV CC) based Solar Charger makes it more reliable than any other PCU in the market. It doesn't require any RTC for the Solar Detection, also it improves battery health by 200%.
As it has own Solar voltage and current sensing and it has smart logic inside, it doesn't require any RTC. It gets true power from solar and shows transparently
It has smart mode which ensures the maximum usage of solar power and less wastage, when the battery is charges it disconnects mains and make inverter to run untill battery is dropped to certain level. A true PWM PCU.
