The most common types of solar inverters are string and central inverters, used as power conversion systems for grid-tie solar applications.

They comprise a DC-DC conversion stage, to adapt voltage levels and implement the Maximum Power Point Tracking (MPPT) function, to maximize energy transfer from the panel and a DC-AC conversion stage to correctly shape current and voltage waveforms transferred to the AC grid. A solar inverter has an anti-islanding function that guarantees safety in case of AC disconnection.

With power ranging from a few kilowatts for solar string and multi-string inverters to tens or hundreds of kilowatts for solar central inverter solutions, the trend is to use topologies with very high input voltages (up to 1500V).

We offer a broad range of silicon-carbide (SiC) power MOSFETs - with the industry's highest operating junction temperature of 200 °C - and trench-gate field-stop IGBTs, that can be also combined into our high-efficiency ACEPACK power modules. Together with galvanically-isolated gate drivers and high-performance STM32 microcontrollers, we enable engineers to design high-efficiency string and central solar inverters. In addition we have a range of wireless and wired connectivity solutions.
