No, its not a hybrid inverter. You can add batteries as what is known as an AC battery pack. In short this would be a seperate inverter and battery.

Thanks for this. So, is this a replacement that will do both or an addition to an SB3000 - I guess in other words what's the best way to go? Thanks again

I coudn't find the sunny boy 3000 on the sma website, that link was all I could find.
Inverters are here: https://www.sma.de/en/products/solar-inverters
if I understand correctly anything with 'tri' in the name is 3phase and unless your property has 3phase grid supply it will not be useful, have a look in your meter cupboard to work out what you've got and have a search of your electricity supplier website, mine had a useful FAQ.
Assuming the SB3000 is a string inverter then this should help understand how it links together.

battery inverters are here,
https://www.sma.de/en/products/battery-invertersthe "sunnyboy storage" range appear to be for high voltage batteries (usually much higher than 48V)
the "sunny island" systems appear to be for lead acid or LiFePO4 batteries
https://www.sma.de/en/home/store-solar-power-use-flexibly
I've not read up on the sma systems, so I'm not familiar with them, TBH I find their diagrams a bit confusing as the various red and yellow items don't have a key or legend to identify them
hopefully someone more familiar with sma kit can pitch in.
hope this helps rather than hinders

Red is grid tied, yellow is off-grid
Leave your existing system alone and fit an AC battery pack. That way you do not risk your FiT payments being stopped because you have altered the system. There's lots of AC battery options, and as much as I think SMA are a quality product, simple fact is the Chinese have ripped off their products and sell them for far less money. Chinese's gear has vastly improved in quality, because they have ripped off designs, but they are so much cheaper to buy it's hard to justify buying SMA anymore. In 20 years it might prove to be false economy? Also worth checking out LG batteries or other non Chinese brands if you don't want to be sending money to a dictatorship.
