Brian, Could you speak a bit more to this, please? My understanding is that the need with a string (or, I suppose, micro-) inverter and a battery-based inverter is for a way to disconnect full batteries from being overcharged when the grid is down and sell is disabled.

HI Larry, I'll chime in here with the other option, ie no batteries at all. Instead its a back up generator. I've found them to be much cheaper, and if you are expecting a longer outage then weather is usually a problem ie its overcast and therefor you'll need a backup for your battery system

Allan, You're not the only one with your eyes spinning here. Let me clarify a bit as I think you are making it more complicated than it is. There is no need for a manual switch. The GT inverters feed into the sub panel which is being fed by the Magnum. Since the Magnum is fed by the main panel

AFRA is a setting that is used when the SI is in an off-grid situation (can be grid tied, just that the grid is not available). If there is a generator that is providing power at a higher frequency, when the Sunny Island disconnects from the gen, it will lower the frequency (below 60Hz), to
