What is a solar micro inverter?

A solar micro inverter helps maximize energy yield and mitigate problems related to partial shading, dirt or single PV panel failures. A microinverter is composed of a DC-DC converter implementing Maximum Power Point Tracking (MPPT) and… Read more Would you like a guided tour to discover ST's new look?

How do APsystems microinverters function?

APsystems microinverters work by tying directly to the low-voltage PV module and connecting to the public power grid via standard AC voltages. This enhances worker and homeowner safety, and eliminates the possibility of high-voltage DC “arc” fires, unlike central inverters with high DC voltages in the hundreds of volts.

How a microinverter works?

Microinverters typically rely on two-stage power conversion. First, booster or maximum power point tracking (MPPT) stage is used to boost and maximize the energy harvested from the PV panels. Then in the inverter stage, AC voltage is generated, that is compatible with single or three phase gird.

What voltage do APsystems microinverters connect to the grid with?

APsystems microinverters connect to the public power grid via standard AC voltages. Unlike central inverters with high DC voltages in the hundreds of volts, APsystems microinverters tie directly to the low-voltage PV module, enhancing worker and homeowner safety, and eliminating the possibility of high-voltage DC “arc” fires.

How do microinverters optimize solar module output?

APsystems microinverters independently optimize the output from each solar module, giving you more power. With a conventional “string” inverter system, the least-performing module determines the productivity of the entire array.

How much power does a microinverter convert?

Microinverters convert power at individual photovoltaic (PV) panels and are usually rated at below 400 Watt for single PV panels and up to 1.5 KW for multiple PV panels. Microinverters typically rely on two-stage power conversion.
