AC-coupled systems first convert solar panel-generated DC power into AC power via an inverter. Appliances use this AC power, while excess energy charges the battery through a charger, converting AC back to DC for storage. The energy flow is: Solar panels → Inverter → AC power → Appliances/Grid. [pdf]
A DC UPS is a power system that provides uninterrupted direct current power when the primary power source is disrupted.
