We build custom homes and have a project under construction which will have 320-amp single phase service. This service will be split into two panels. The first would be a 200-amp panel for the most essential circuits. The second panel would have the remaining circuits.
The desire is to have the first panel be a grid-tied solar system. A backup generator for this panel is also planned. In the event of a grid outage, the desire is to be able to use solar to the maximum extent and then use the backup generator to supply the remining power. Incorporating a battery into the system would be one way of doing this.
I have done a search on this topic. Some of the threads have diagrams going back quite a few years. See 2010 image as one example.
In terms of the latest thinking, some questions:
What is the latest thinking on how to do this?
Does anyone have a recent diagram of how best to do this?
Recommendations on batteries – manufacturers of batteries and/ controls, way to size the batteries?
What automatic and manual switches are available to bring the generator online?
What else should we be thinking about?
Thanks very much!
