A solar inverter is used to convert the Direct Current (DC) electricity generated by solar panels into a usable form of Alternating Current (AC) that can be utilized to integrate with the grid or run AC loads/appliances. Micro inverters are typically attached directly to individual photovoltaic modules in order to extract the maximum power from each module. These are exceptionally reliable and typically come with a 15-year warranty. They are highly efficient and can potentially produce more power than a string inverter; however they can add substantial cost to a solar project.
