PolicyGuy:Our PV installer called by this afternoon and using access info provided by Frontius in Australia he tweaked a few settings on our inverter. Essentially pulling back some of its sensitivity to grid voltage fluctuations which should hopefully reduce the outages we're experiencing.
... grid voltage kept droping below 230V until about 3:30pm during which time the inverter repeatedly tripped out and on again. grey peak after is export for remainder of the day. Disappointing waste of a sunny day due to Powerco's infrastructure failing to perform and our installer has approached Powerco for the okay to widen out the inverter's grid voltage acceptance parameters.
Powerco is also my Lines Company, in suburban Whanganui.
I just looked in my UPS log file for the last week:
Some of his comments regarding the ability of Powerco's infrastructure, particularly in Taranaki, to cope with the demands coming from PV inputs and EV charging were enlightening. In his having seen the Australian grid infrastucture upgrade to cope it seems we are behind the game in that regard in NZ. 2% PV uptake here compared to ~35% in AU we have quite a bit of catching up to look forward to. Hopefully TPTB over the next few years are aware of what is involved in electrifying NZ.
