An inverter is the most important component of a household solar power system. It serves as a converter, converting the power generated by solar panels into energy that can be used by appliances. The sort of inverter you select is determined by the type of solar power system you want to install. Grid-connected solar power systems require high-efficiency power inverters to achieve optimal performance. There are also high-efficiency solar inverters for off-grid solar power systems that can charge batteries using both solar and grid electricity.
