I must have been outside when it went out as normally there is a beep. TV, Internet, computers everything was working fine
The Oven, Heat Pumps and Dryer is the only thing not powered by batteries in a switch over. I have two large batteries that support the current draw.
I sat down at my computer and saw the web page monitoring my solar system showing only 0.68kWh in full sun at 2:30PM. It matched exactaly the usage and there was also a Red X over the grid.
That makes sense as the overage of what I need goes back out to the Grid and shutting that off would enable safety to anyone working on the line.
As an experiment, I cranked up the heat from 69 to 72. I got a commincation error(Heat Pumps off) and the system automatically switched to the Gas furnaces.
Now using and producing 2.62kWh
I let the house heat up to 71 and then set the thermostat back to where it was. Now using and producing 0.6kWh of power
The web page says at this rate with no sun or grid, the battaries will last 47 hrs. Being winter, it wouldnt last that long with Furnaces coming on, But the sun will come up tomorrow
You don't need the large battareis I have to run in a power outage with sun, any supported battery size will enable this. Battery sizing determines how long and at what load could you run. Key for me was do I want to limit the loads (Other than 220V) or be able to keep doing what we are doing with Heat (Gas). I do have one 220V outlet in the garage that is not disabled by a power outage. It just worked out that way as I did not load shed the garage panel (Seperate box)
