Micro inverter solutions

Microinverters convert power at individual photovoltaic (PV) panels and are usually rated at 400 Watt for single PV panels and up to 1.5 KW for multiple PV panels. Microinverters typically rely on two-stage power conversion. First of all, the DC-DC stage or booster converts variable DC voltage into a fixed DC voltage (typically 40 V to 60 V). At the same time, maximum power point tracking (MPPT) is used to maximize the energy harvested from the PV panels (typically F_SW = 100 kHz).

First DC-DC stage or Booster, converts variable DC voltage into a fixed DC voltage (Typ. 40 V to 60 V), at the same time ensure maximum power been extracted from PV panel via MPPT (Maximum Power Point Tracking) technique, second, the DC-AC inverter stage converts DC into grid compatible 1Φ AC power. Contrary to String inverters, microinverters are attached to one, two or four PV-panels and perform MPPT tracking per PV-module separately.

The latest generation silicon carbide semiconductors and CoolSiC™ MOSFETs enable a significant increase in power conversion efficiency in solar power generation systems and associated energy storage. Read more about these applications and how lower loss not only saves energy, but also results in smaller and lighter equipment with lower capital, installation, and maintenance costs.
