GM, not wanting to be pedantic, but the 1713W shown on your meter appeared to be at 195V. If I have got it right, by the time that 195V is converted to 240V as it has to be, then the 1713W becomes 1392W. Or have I got it wrong?
Of course you want to be pedantic.
But that's OK as lots of folk are pedants! (vbg!)
What you overlooked was 1700 watts can come in two forms - high voltage and low amperage or low voltage and high amperage.
It's the kilowattt amps by so many killowatt hours that counts!
The progressive output meter on my gizo-box and the input meter on my Actew-AGL power board both tell me that 3.4 kilowatt hours were 'sold' to Actew-AGL from fire-up at 3.00 pm until sunset.
My installer told me to phone him if the 1700 (or whatever figure) did not keep pace the 1700 (or whatever) figure on the input meter as that means something has gone awry!
There is a downside to solar power. When linesmen are about to mess with live overhead wires, they normally only have to turn off a main power switch at a sub-station.
BUT that has no effect on solar producers who are pumping away madly - unaware a linesman is about to be Zapped! So the linsemen need to know where all solar producers are located and switch them off one by one before starting work and (hopefully) returning one by one to switch solar systems on again when the work is done.
Hence a warning from my installer:
Before phoning him for a warranty call-out, check the meter box to see if a linesman forgot to turn my system back on after fixing a line fault!
Like all new things, there are 'Traps For Young Players' in the solar caper too!
