Hello all G99 etc consumer advice What are the standby running costs to monitor grid fail and and eventual inverter physical separation ? Anyone know ?
Q: How is physical separation achieved for islanding protection when grid is detected as down ? There is much tech mumbo jumbo " phase detection " zero crossover " but no genuine answer as to what the standby costs of running all this this actually is
Appears ( however fail is detected ) final physical separation is achieved by a plain old electro mechanical contactor ? It is simply de-energised Contacts separate and we are done ?
Could it be that these power devices are maintained energised all year 24/7 consuming power until here is an issue ?
If so can the solar grid tie industry tell us what power is consumed in this effort and where does it come from ?
ciao Ms Otis
