Zappi v2.1 / Zappi 3
Zappi Installation UK
Zappi from myenergi is the UK's most popular solar-aware home EV charger. The Eco+ mode diverts surplus solar to the car (charges only when generation exceeds consumption), or you can let it pull cheap-rate grid via Octopus Intelligent. We install Zappi v2.1 and the new Zappi 3.

FAQs
Zappi questions
Zappi v2.1 vs Zappi 3?
Zappi 3 is the 2024 refresh — better app integration, refined Eco+ logic, V2G (vehicle-to-grid) ready hardware. v2.1 is still excellent and £150 cheaper. For new installs we recommend Zappi 3 unless budget is tight.
Does Zappi work without solar?
Yes — Boost mode runs at full 7 kW any time. Without solar, you lose Eco+ but can still use Octopus Intelligent for 7p/kWh smart-charge windows.
Is Zappi compatible with Octopus Intelligent?
Yes — Zappi v2.1 (latest firmware) and Zappi 3 are both certified for Intelligent Octopus Go. Octopus picks the cheap window automatically and tells the Zappi when to charge.
Do I need a Harvi?
Only if you don't have solar OR your solar inverter is on a separate consumer unit. The Harvi (£40 wireless module) lets Zappi see grid import/export from a different location.
