In the system shown, solar panels provide DC power to the inverter. The inverter can then use this power to run your home and charge the batteries simultaneously. When batteries aren’t charging, they can supply DC power to the inverter, which can then power your home, especially at night when solar power is low. If solar and battery power aren’t enough, the grid steps in to supply AC power to the inverter. This setup ensures constant electricity supply, making the system reliable and efficient.

For those without solar panels, the system still provides a backup solution during load shedding. In this scenario, the batteries serve as the primary backup, ensuring continuous power supply when the grid is down. However, without solar panels, the batteries rely on grid power for charging. This means that during times of load shedding or when solar energy is insufficient, the batteries will need to be charged by the grid to maintain power supply.

However, the system is designed for flexibility and expansion. Later on, solar panels can be added to the setup to achieve full functionality. Once solar panels are integrated, they can charge the batteries directly, reducing dependency on the grid and enhancing the system’s overall efficiency and sustainability.
