€1500 can already get you 16.1kWh.

The investment point still stands, though you could argue both come with risk/reward, energy prices aren't guaranteed to be stable.

Alternative systems are closer to 5 years payback if you have access to off peak energy. 3-4%/year degradation is very high, battery packs available in the UK from Fogstar are rated at 8,000 cycles with a 95% depth of discharge.

FWIW my high voltage battery pack has almost 365 cycles and is still at 100% state of health.

Interesting - how are you interacting and orchestrating this?

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.

Coincidental that the domain was registered on the same day... it's fine to say you were inspired to build from the discussion.

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.
