You guys aren't suggesting that there is a conspiracy between the high end power generation companies to make more money and let the poor plebs ( read us ) think we are doing our bit with renewables are you. I was looking for the tongue in cheek emoji but I think it must be on my phone.
George, What I was sort of saying is that you could remove your off peak tariff meter and switching relay and get a time clock fitted so you get to choose when your solar heats your hot water. Without going back through this thread I think you mentioned that twice a day your input to grid shuts down due to over voltage . That would be the ideal time to heat you HW. As you have east and west facing arrays you could easily do a morning and arvo shift and still feed in to grid and have hot water as well. Pretty much as T1 states. But his technical English is better than mine.

As we've found locally if you have a big solar system in the same area as yours and they shut machinery etc down on weekends, holidays and on work days at 5pm then the grid voltage goes up and all the smaller systems shut down as the grid voltage rises.
So the ideal situation is to NOT encourage neighbours to install solar so that your system keeps feeding into the grid.
We don't have the problem in our street but others in town with business premises with large solar systems nearby do.
The mate I was talking about in an earlier post, his system trips out to overvoltage at around 4-5 pm most workdays and weekends all the time depending on the weather.

Our inverter AC voltage limit is set at 258V and we have not had any shutdowns recently however, we do get cutbacks when the output exceeds 250V. Yesterday the first cutback occured at 8:10 with the voltage of 253.8.

George, how many output watts at that time?
David, 3837.4 @ 15a.
[Edit] Despite the problems, having the solar is reducing the electricity bill with our last bill from 12/7 to 15/11 being $128.31 when paid on time by 14/1.

This is one of the advantages of (smart) battery storage.
It stores the energy and trickles it n over the night.
Better than that, well tuned it can replace the peak power for the house that the energy companies charge top $$ for if you purchase it from the grid. The pittance they pay for the feed in and then sell it next door at top $$ is close to criminal as far as morality goes, but quite legal in our "big boys make the rules" society we have at the moment.
The question that then needs to be asked, how many yrs for the pay-back to go completely off grid so you no longer have the connection fees and account charges? The restrictions on the amount of solar you can have no longer apply and the unreliability of the grid is a thing of the past.

If I was the only one to be considered re the installation of solar we would not have proceeded due to the payback period but as Julie is considerably younger and intends to continue residing at our current address for the forseeable future it was considered to be financialy beneficial however, adding the cost of batteries would completely change the situation.
