Solar inverters play a key role in solar installations by converting the direct current generated by the solar panels into alternating current that can be used in households and the electricity grid. Inverters optimise the overall performance of the solar system by extracting the maximum available energy from the sunlight. They also continuously monitor the system performance and detect problems or failures early, which assists in maintenance and improves reliability. Solar inverters are mainly focused on generating electricity from solar energy, hybrid inverters allow the integration of solar and battery storage systems, and battery inverters are specifically designed to convert energy between batteries and AC power. Inverters differ in technical specifications such as rated power, input voltage range, efficiency and protection functions and other features. The choice of an inverter should fit the size of the solar system or battery storage system and the local conditions.
