During the day, our solar is producing an EXCESS generation of up to 20kW per day (around 30 -40kW per day). Our grid meter is not so smart, so we feed it back into the grid for free at the moment. Our total power usage on average per day is about 26kW of which we use (get charged for ) on average 12Kw overnight when there is no solar production, so, basically, a low constant usage powering fridges, freezer, lights, TV, kid's devices etc. If we use the ducted AC, I see that it consumes between 4.5 and 7.4kW per hour extra when it is powered on.
There is one household circuit that supplies all of the above appliances except the A/C.
I have access to about 30kW of new AGM batteries configured @ 48V.
So, what would the best way be to..
1. Take that circuit off-line and attach to a Victron Multiplus 2 or Quattro
2. Attach the Victron to the excess electricity that the solar produced during the day, charging the battery bank.
3. Use the battery bank for night time power for the above appliances, thus eliminating my 12kW night time consumption.
Thanks in advance
