Solar inverters primarily convert DC power from solar panels or batteries into AC power for home or business use, similar to conventional inverters. Key differences include features like Maximum Power Point Tracking (MPPT) and anti-islanding protection, which enhance efficiency and safety in solar applications. While some argue that these features are not essential within the inverter itself, they contribute to the overall functionality of solar systems. Additionally, MPPT can be sold separately, indicating a modular approach to solar power management. Ultimately, despite these distinctions, both types serve the fundamental purpose of power conversion.
