Inverters with a power rating of 10–19 kW are designed for larger single-family homes, duplexes, and smaller commercial facilities where the solar system already serves a more serious energy demand. These inverters are usually made in a three-phase design and have multiple MPPT inputs, which allows for the efficient operation of solar panels with different orientations or tilt angles.

Models in this category operate with outstanding efficiencies of up to 98% and offer features such as AFCI arc fault protection, IP65-IP66 protection, and remote monitoring from a smart device or web platform. 10-19 kW inverters are often chosen for scalable solar systems, as they can easily be integrated with battery energy storage. Their efficient, safe and flexible operation makes them an economical choice in the long term.
