Battery storage.

A battery is the component that decides whether a smart tariff actually saves you money. Sizing is more nuanced than installers tend to make it sound, and the headline kWh figure rarely reflects what you can usefully cycle each day.

Coming soon

This section is intentionally thin at launch. The full guide, recommendation and any calculators will appear here as they are written. Expect the first proper update within a few weeks.

Read what Energy Stack is for the editorial approach, or get in touch if you want to be notified when this section goes live.

What this section will cover

  • · Usable versus nameplate capacity, and how to read a datasheet
  • · Hybrid inverter versus AC-coupled, with a worked example
  • · Sizing for tariff arbitrage rather than blackout backup
  • · Round-trip efficiency, depth-of-discharge and cycle warranties in plain language
  • · V2H and V2G as a battery alternative, and where they actually work today
