Solar Inverter

Fronius Primo solar ‘string’ inverter

Solar panels generate DC electricity which must be converted to alternating current (AC) electricity for use in our homes and businesses. This is primary the role of the solar inverter. In a ‘string’ inverter system, the solar panels are linked together in series, and the DC electricity is brought to the inverter which converts the DC power to AC power. In a microinverter system, each panel has its own micro-inverter attached to the rear side of the panel. The panel still produces DC, but is converted to AC on the roof and is fed straight to the electrical switchboard.

The advanced string inverter systems which use small power optimizers' attached to back of each solar panel, in monitor and control each panel individually and ensure every panel is operating at maximum efficiency under all conditions
