As the demand for renewable energy rises in South Africa, solar power has become an essential solution to combat electricity shortages and rising costs. At the heart of every solar energy system lies the inverter, a critical component that converts direct current (DC) generated by solar panels into alternating current (AC) for use in homes and businesses. In South Africa, three common types of inverters exist: string inverters, central inverters, and hybrid inverters. Among these, string inverters have gained popularity due to their efficiency, flexibility, and cost-effectiveness.
