Quick verdict: These two chargers share more than most comparisons — both include built-in PEN protection, both support solar, both have WiFi/Bluetooth/Ethernet, and both are OCPP-capable. The main differences: Alpha7 is £240 less, entirely UK-manufactured, and includes solar as standard without needing an optional CT clamp. EO Mini Pro 3 is more compact (A5 notepad), supports three-phase, and now integrates with British Gas/Hive for customers in that ecosystem.

📖 Plain English

These are two very capable chargers that are more similar than different. Both have PEN protection built in, both have solar capability, both have WiFi/Bluetooth/Ethernet. The key questions are: Do you need OCPP? (EO wins.) Do you need three-phase? (EO wins.) Are you a British Gas/Hive customer wanting joined-up energy management? (EO wins.) Do you want the best value from a 100% UK-manufactured charger with solar as standard? (Alpha7 wins.)

A Note on EO Mini Pro 3 Availability

The EO Mini Pro 3 was originally manufactured by EO Charging, a UK brand. In 2024 EO Charging was acquired and the home charger range came under Juuce Limited, operating primarily through the British Gas/Hive ecosystem. The EO Mini Pro 3 is now sold and supported through the Hive channel, meaning British Gas customers get an integrated experience — Power+ tariff integration, 25% off electricity per charge, and a single smart home platform.

For non-British Gas customers, the EO Mini Pro 3 remains available through installers and electrical trade channels, but the Hive ecosystem integration is the product's strongest selling point. Without it, the price premium over the Alpha7 is harder to justify for most domestic installs.

Warranty note The EO Mini Pro 3's 3-year warranty is conditional on installation by an EO-approved installer. Non-approved installer installations receive a shorter 2-year warranty. Always confirm approval status before specifying.

Solar Integration: Standard vs Optional Extra

The Alpha7 includes solar integration as standard — a current clamp is fitted during installation and solar mode is activated via the FastAmps app. No additional accessories required.

The EO Mini Pro 3 supports solar — but enabling dynamic load balancing and solar integration requires the optional CT clamp accessory (sold separately). Once installed, the EO app provides solar monitoring and charge optimisation. For customers with solar, factor the additional CT clamp cost into the EO quote.
