John,
Thanks for that bit of information. I have a customer with a SB5000 and recently added a Sunny Island with 8 L16 batteries. This answers their question as to what they will do in an extended outage with no sun. I wanted to suggest a small backup generator but wasn't sure h
SMA Sunny Island also does this but also discharges battery in parallel with
the generator to create a "virtual generator" that is larger than the actual
generator.
Just set the max generator current and it does the rest.
