EO Mini Pro 3 Review UK: Specs, Price & Solar Fit

The EO Mini Pro 3 is a British-made, fist-sized smart charger that's already namechecked across this site's EV charging guides — as a comparison point in our best EV charger for solar panels roundup, and in a head-to-head against the Ohme ePod in EV charging with solar — but it's never had a review of its own. This one draws directly on EO's own installation and commissioning guide rather than retailer marketing copy, so the specs below are what an installer actually works from on the day.

EO Mini Pro 3: specs and price in 2026

The EO Mini Pro 3 is a single-phase, 7.2kW charger measuring 230 x 151 x 125mm — about the size of an A5 notepad — making it one of the smallest mainstream smart chargers sold in the UK. Per EO's own installation and commissioning guide (version 2.0.0), it's rated IP54 for ingress protection and IK08 for impact resistance, suitable for indoor or outdoor mounting with no access restrictions, and carries a Class I electric-shock protection rating as Mode 3 charging equipment. Operating temperature runs from -25°C to +50°C, with the unit derating its charging rate by 25% if internal temperatures exceed 65°C.

• Power output: 7.2kW single-phase, sold as an untethered (socketed) unit taking a standard Type 2 cable
• Connectivity: Wi-Fi, Cat 5 Ethernet and Bluetooth as standard, with 4G/GSM available as an optional extra for sites with a poor Wi-Fi signal
• Earthing: built-in open-PEN-conductor (broken-PEN) protection on the single-phase model, meaning no separate earth rod is normally required on a TN-C-S (PME) supply
• Leakage protection: internal 6mA DC leakage detection (RDC-DD, to IEC 62955), with an upstream Type A RCD still required per the installation guide
• RFID: not fitted — EO's own product summary table lists RFID as "No" for this model, unlike the commercial-focused EO Genius range
• Warranty: 3 years, per this site's own product listing
• Price: £577.00 ex VAT for the unit alone, per this site's own listing, before installation

That price sits above the Zaptec Go and Easee One, both of which undercut it on unit cost while offering similar PEN protection. Our wider best home EV charger UK roundup lines it up against tethered and pricier alternatives if you want the full field, and the EO Mini Pro 3 vs Ohme ePod comparison covers the closest like-for-like match-up.

The CT clamp inputs: load management and solar, not solar divert

The EO Mini Pro 3 ships with a four-pin CT connector block supporting two separate clamp inputs — one for load management (CT1, labelled "ALM" in EO's wiring documentation) and one for solar (CT2) — but this is app-scheduled smart charging rather than the real-time, second-by-second surplus tracking that dedicated solar-divert chargers use. EO's installer guide confirms the solar CT input exists and is wired identically to the load-management clamp, feeding data back to the EO Charging app and cloud platform for scheduling decisions.

In practice, that means the Mini Pro 3 can be configured to favour charging during daylight hours or against a solar-generation profile, but it doesn't match the moment-to-moment PV-output tracking built into the myenergi Zappi or Hypervolt Home 3 Pro. Our own best EV charger for solar panels guide lists the Mini Pro 3 as a notable mention precisely because of this gap — a genuinely smart charger, but not a true solar-divert one. If real-time surplus-only charging is the priority, look at the Zappi or Hypervolt first; the wider solar-compatible EV chargers list has the full comparison.

Installation and the warranty small print

EO's installer guide is unusually specific about a few things worth knowing before you book a fitter. The rear cable entry has exactly one permitted drilling point — the guide states explicitly that drilling anywhere else on the housing invalidates the warranty and risks damaging the internal PCB. Socketed units need mounting with the enclosure's lower edge at least 0.9m above ground level, and the connector block accepts Live, Neutral and Earth on a single terminal block behind the fascia, which comes off as one piece with an "Installer Access Label" the fitter photographs for commissioning. Maximum installation altitude is 2,000m and the input cable terminals take a 1.2Nm torque setting — both spec-sheet details rather than anything a homeowner needs to act on, but useful if you're vetting an installer's familiarity with the unit.

Wi-Fi setup is worth flagging too: EO's own guide recommends checking signal strength before committing to Wi-Fi as the connection method, with a fallback to Ethernet or the optional 4G/GSM module if the household's 2.4GHz signal is weak at the charger's mounting point — a genuinely useful pre-installation check most retailer spec sheets skip.

The OZEV grant

As of 2026, the domestic Electric Vehicle Chargepoint Grant pays up to £500 per socket, but it's restricted to renters, flat owners, and households without off-street parking who rely on street charging — homeowners with a driveway are not eligible regardless of which charger they choose. See our EV charger installation guide for the current full eligibility rules and realistic all-in installed cost ranges.

Who the EO Mini Pro 3 suits

The EO Mini Pro 3 is the right pick for households that want the smallest possible charger footprint without sacrificing app control, OCPP compatibility, or built-in PEN protection — and its dual CT inputs mean it can still respond to a solar-generation profile even if it won't chase surplus in real time. It's a weaker fit for anyone prioritising tight, real-time solar-divert charging, or who wants RFID access control for a shared driveway. If either of those matters more than the compact size and price, the myenergi Zappi or Hypervolt Home 3 Pro are the better starting points.
