Good if you can get by cheap.
Maybe a UPS, or a 12V battery and solar charger, to keep communication gear running during an outage.
If you browse eBay and other sources, maybe you can pick up a Sunny Island new or used cheaper. Add a transformer and it can take the place of a 120/240V backup generator to power your panel. It can keep an AGM battery floating while grid is up. When grid goes down, turn off the breaker feeding Sunny Island (so it doesn't power itself), flip the interlocked generator breaker, and the house is up on Sunny Island with Sunny Boy supplying PV. I think Sunny Boy set to Rule-21 frequency-watts instead of UL-1741 (if not already) will make it play nice. Might cost $5k depending on the Sunny Island price which could be $3000. About $1200 for 100 Ah 48V AGM, cheap used transformer.
