A solar battery system stores energy generated by solar panels for later use. This allows homeowners to utilize solar power even when the sun isn't shining, such as during the night or on cloudy days. The stored energy can help reduce electricity bills and provide backup power during outages. These systems typically consist of solar panels, an inverter, and batteries. The inverter converts the direct current (DC) from the solar panels into alternating current (AC) for home use. Batteries come in various types, including lithium-ion and lead-acid, each with different capacities and lifespans to suit different energy needs.
