What is solar 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 micro inverter 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.
There are also more advanced string inverter systems which use small power optimisers attached to back of each solar panel. Power optimizers are able to monitor and control each panel individually and ensure every panel is operating at maximum efficiency under all conditions.
