Sizing inverters to optimise solar panel system efficiency

February 6, 2017

Thumbnail image for Sizing inverters to optimise solar panel system efficiency

The efficiency of the inverter drives the efficiency of a solar panel system because inverters convert Direct Current (DC) (as produced by the solar panels), into Alternating Current (AC) (as used by the electric grid). This leads many to wonder what effect over-sizing or under-sizing an inverter will have on overall system efficiency. This entry […]
