The inverters shut down if power goes out. Im not using any battery backup. The solar only offsets a fraction of my overall power usage, never makes it onto grid.

Here is the answer! Wink

Thank you! That seems like it would cut down on costs as that is a good amount of batteries. I still wonder the price of it.

I have never seen numbers that allowed me to justify it in past. But I would love for someone to show some numbers that make solar or wind with ROI that is not horribly long.

I will chime in since I just installed a 7.65 kW system mostly to offset my electric bill from mining, however, it is completely a grid-tie system. I paid $.65/watt including shipping (bought from a wholesaler on eBay), $2800 for 2 inverters, installation was $1.10/watt (1 inverter would have worked if I went with SolarEdge w/optimizers). I had to take a break from mining when my Edison bill hit $900 last November for running about 8 TH. Not entirely sure if this system will help in ROI for running S7s, on the other hand, Edison buys back extra power @ ~~$0.9/kW~~ $0.09/kW..
