Absolutely. A local company is currently advertising 12 470w panels, 10kwh storage for £7695 fully installed with additional pannels fully installed for £200 each. /r/uksolar is a great resource for comparing quotes.
In the UK, where the OP is from, the equivalent of the battery you linked is available from Fogstar for £1850 (includes 20% VAT), shipped. Without the VAT that works out at ~$2000. A compatible high end 9kW inverter is available for around £1200.
The ROI is really attractive once you look past the overpriced kit.
