Thanks Marlin
I am a solar convert for sure.
We are running a substantial solar array - 52 roof panels that at peak churn out around 14.5 KW in real time power around mid day. I am running these into a 15 KW 3 phase DC/AC inverter so we are basically net power neutral (produced/consumed ) over the entire year, but we are still hooked up to the grid. Unfortunately day surplus goes into the grid for free and any extra at night comes out of the grid and we pay for it.
For the whole of last December the system produced 3.6Mwh of power which off your roof is not a bad effort . Over the four hour spread through midday it can run two 3 phase AC units on the solar output alone - enough to cool our place at zero grid power.
If I incorporated a 15 KWH 3 phase battery pack we could almost become grid power free, but I would still need to be grid connected due to the type of inverter. It cant run as a stand alone.
Still waiting for the right kind of battery at the right price ! Up until now that size has been pretty expensive.
Also the potential in future to use an electric car as the battery buffer is now possible as after 3 years of messing around the muppets in Canberra have finally approved a VTH ( Vehicle to Home ) charging and earthing standard. I am pretty sure the US has had a working solution for at least three years so you probably know all about it.
So that is also a brilliant option for an instant very large battery buffer, if you have a battery on wheels in the garage - which I dont !
