📖 Plain English

Ohme is like a very clever alarm clock for your car — it knows how much charge you need, checks live electricity prices, and fills your battery at the cheapest possible time without you having to think about it. The Alpha7 is the British-built all-rounder: excellent solar integration, lower price, no need for a PME board, and made entirely in the UK. Unless automated bill-minimisation is the main brief, Alpha7 wins on overall value.

Where Fast Amps Alpha7 Has the Edge

🇬🇧
Entirely UK-Manufactured
Designed and built in Shrewsbury. Supports British jobs in Birmingham, Halesowen, and Leamington Spa.
☀️
Solar — Standard
Dynamic solar charging included. Ohme's solar diversion is secondary — its primary design is tariff optimisation.
🛡️
Built-in PEN Protection
No external PME device or earth rod required on PME supplies. Ohme requires one — adding £100–£200+ to install cost.
🔌
Untethered Option
Available tethered or untethered. The Ohme Home Pro is tethered only — no socket option available.
🌐
Ethernet Available
Wired network connection for reliable installs in garages or outbuildings. Ohme is WiFi and Bluetooth only.
💷
£200+ Lower Price
From £399 vs Ohme's £600+, with no extra PME hardware needed. Total installed cost advantage is significant.

Where Ohme Home Pro Has the Edge

  • Vehicle battery API: Reads your car's actual state of charge via the cable — knows exactly how much it needs and charges only that, at the cheapest time.
  • Octopus Intelligent integration: Native API connection automatically shifts charging to cheapest off-peak windows — zero manual scheduling required.
  • Built-in 4G SIM: Stays connected independently of home WiFi — useful in rural locations or garages with weak signal.
  • On-charger LCD display: Check charge status without reaching for your phone.

Frequently Asked Questions

Does the Fast Amps Alpha7 need an earth rod on a PME supply?
No. The Alpha7 includes built-in PEN fault detection in accordance with BS 7671 Section 722. No external PME device or earth rod is required.
Does the Ohme Home Pro need PME protection?
Yes. On PME (TN-C-S) supplies, an external PME protection device or earth rod must be installed. This is an additional cost that installers should include in quotes.
Which is better for solar, Alpha7 or Ohme?
The Fast Amps Alpha7 is the stronger solar choice — dynamic current clamp integration is standard. Ohme's primary design strength is smart tariff optimisation, not solar maximisation.
Is the Ohme Home Pro available as an untethered charger?
No. The Ohme Home Pro is tethered only. The Fast Amps Alpha7 is available in both tethered and untethered configurations.
Does the Ohme work with all EVs?
The vehicle battery state-of-charge reading works with many popular EVs but not all. Basic 7.4kW charging works with all Type 2 vehicles. Check Ohme's compatibility list for your specific car.
