What are my options for a 20kwh+ battery?

If the cable was correctly sized to carry 7 kw from the house to the garage for the charger then it will be large enough to carry up to 7kw in the other direction ie from the battery inverter to the house. 

 

FIT rules changed a few years ago and you can chop and change a system like adding batteries and probably change the inverter for a hybrid if that suited you better

 

 

Thank you for all that, now that you say it... It makes perfect sense... If a cable can carry electricity in one direction... Spooky that it can do it in reverse!! 🤔😂

How easy are these frogstar type units to install? Is this default job for an electrician, or does it need someone who has specialist knowledge? 

 

I'm very tech literate (but entirely new to home energy) , so would research the right combination of inverter to suit my needs... But could my normal sparky install it in a few hours?

AFAIK it's electricly simple. You do need an inverter that supports the battery. The tricky bit is configuring the inverter to talk to the battery. That will likely be outside of a non-solar installers wheelhouse. Equally, while simple if an electrician is not used to working on 48V stuff they may not be the right person.

 

The assumes the inverter is already installed. Installation of the inverter is a bit more complex, again something for an electrician used to doing solar related installs.

There’s a vid on this page, the guy uses a sunsynk inverter with the fog star battery, this almost makes a shopping list quite easy to assemble.
