Yes, I understand. I'm thinking that IF someone is installing a major solar system that what you describe would be calculated, charged and installed along with it. Therefore the blanket statement that it's not easy doesn't sound right. It's expensive but it can be done so why just toss that idea away?

I did some research 15 years ago when I was thinking about a combination of wind and solar - in my mind I would have built a cement block battery shed cooled in a few ways; shaded, roofop wind turbine vent. I have one right now that works pretty good on the shed and that doesn't even have shade.

Well yes, most solar installs will have some batteries, but I don't think they usually include a big pile to run the house overnight, the solar installer is expecting/assuming that you just pull from external power overnight/cloudy days. The whole system install will have inverters and everything, but it may not be designed to handle a lot of battery power. Most people that have the system installed likely aren't paying for a ton of extra batteries either. So yea, if you already have a system it's not that complicated to add more storage, but it's a LOT of space and arc/fire risk for something, do you really need?
