March 27, 2017
Thumbnail image for How does maximum power point tracking (MPPT) work?

Maximum Power Point Tracking (MPPT) is a technology approach used in solar PV inverters to optimise power output in less-than-ideal sunlight conditions. Most modern inverters are equipped with at least one MPPT input. The below article – which originally appeared as a response by Bradley Detjen to a question on Quora.com – explains MPPT using the most […]

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 […]
