I have two (redundant) banks of panels/controllers/batteries/inverters that I switch between to feed my home's service entrance (when one set of batteries gets low, I switch to the other). An Automatic Transfer Switch (ATS) works fine, except the switching delay disrupts power to the house, which is tough on appliances and sensitive electronics (not to mention flashing all the device clocks).
Anyone know of an affordable 120v Static Transfer Switch (something that switches in 4-5 ms)? They use these in data centers, hospitals, etc., but I can't find one appropriate for a residential application. I'd consider a UPS if I could find one that was fast enough and could switch back-and-forth between the two banks, but I haven't found that either. Seems like an obvious product, so I'm sure someone here has cracked it
