4 Frequently Asked Questions about “PV Inverter System Reliability - RRR Renewable Projects (SA)”
Are PV inverters reliable?
Notably, PV inverters can introduce reliability challenges to the system, if not properly designed. For example, loss of approximately 2.3 GWh energy (36% of the total energy lost) was observed in 350 systems operated by SunEdison, over a 27-month period, due to the inverter failures .
Why is inverter reliability important?
