📖 Plain English

Both are genuinely excellent British-built chargers. The Zappi is like a solar specialist — it squeezes every last electron out of your panels with its ECO+ mode and ties into the whole myenergi home energy system. The Alpha7 is the straightforward British-built alternative: does solar well, costs £300 less, and is simpler to install. If solar is your whole focus, Zappi. If you want a great all-round charger at a better price, Alpha7.

Where Fast Amps Alpha7 Has the Edge

🛡️

Built-in PEN Fault Protection

No earth rod needed on PME supplies. Zappi requires an external PME device — adding cost and installation complexity.

💷

£300+ Lower Price

From £399 vs Zappi's £700+. For most domestic solar setups, Alpha7's solar mode delivers the same practical result.

🔧

Simpler Installation

Bluetooth commissioning, no WiFi required on site, mounting template and fixings supplied. Fast, clean installs.

🔓

No Ecosystem Lock-in

Works as a standalone charger without needing an eddi, libbi, or Harvi to unlock full functionality.

Where Zappi v2 Has the Edge

ECO / ECO+ solar modes: Charge only on surplus solar (ECO+) or blend solar with grid (ECO) — best-in-class solar self-consumption optimisation.
myenergi ecosystem: Integrates with eddi (immersion diverter), libbi (home battery), and Harvi (wireless clamp) for whole-home energy management.
Octopus Intelligent API: Direct integration auto-schedules charging to cheapest available windows without manual configuration.
Three-phase option: Available up to 22kW on three-phase supplies.

PME Safety: A Clear Alpha7 Advantage

On UK PME (TN-C-S) supplies — approximately 80% of domestic properties — BS 7671 Section 722 requires protection against open PEN conductor faults. The Alpha7 includes this built-in, satisfying Section 722.411.4.1 iv without any external device. The Zappi v2 does not — installers must add an external PME protection device or earth rod, adding cost and complexity to every install.

Why this matters External PME devices typically add £100–£200+ to total installation cost. The Alpha7's integrated protection removes this entirely — a genuine practical advantage on the majority of UK domestic installs.
