Enphase home EV chargers: IQ EV Charger and solar integration

Enphase is best known in the UK for solar microinverters and home batteries, and its entry into home charging follows the same logic: a wallbox that talks to the rest of the house's energy system. The current product is the IQ EV Charger 2, sold in tethered and socketed forms and in single-phase and three-phase versions. It pairs with the Enphase App for monitoring, control and access features, and it either integrates with an Enphase Energy System or runs independently as a standalone charger¹.

The headline capability is solar-aware charging. Enphase states the charger works with any solar system, Enphase or otherwise, adapting in real time to enable solar energy¹. Green charging uses available surplus solar energy and works with compatible third-party solar systems as well as Enphase solar³. When paired with an Enphase Energy System, Enphase states the charger can charge from as little as 1.4 kW, low enough to follow modest surplus rather than pulling at full rate¹.

A bidirectional unit is coming. Enphase lists the IQ Bidirectional EV Charger as available in 2026 and expected to launch in late 2026, compatible only with EVs that are ISO 15118-compliant and support bidirectional power flow⁴. The IQ EV Charger 2, available in the second half of 2025, will support AC bidirectional functionality⁴.

The Enphase range: IQ EV Charger 2, dual chargers and what's coming next

The IQ EV Charger 2 is the product a UK household would buy today. It is offered in socketed and tethered configurations across European markets⁷, and the single-phase tethered version is customised for UK smart charging regulations with built-in PEN fault protection and a MID meter for usage tracking and reimbursements². The three-phase tethered version carries the same app pairing and the same choice between integration with an Enphase Energy System and standalone operation⁸.

Enphase also describes dual EV chargers in a variety of power and installation types. The dual unit mounts to a wall indoors or outdoors, uses a single circuit so it is inexpensive to install compared with two charging stations, splits power 50-50 between each car when two vehicles request a charge, and offers full power to the remaining vehicle once one is full, without unplugging⁹.

The forward-looking product is the IQ Bidirectional EV Charger. Enphase states it can integrate with existing Enphase Energy Systems, unlocking home backup, smart charging and grid services depending on site configuration and components present⁵. Its user interface is the Enphase App, with multi-colour notification LEDs and a Dark Start switch, and it supports both 400 V and 800 V battery platforms¹⁰. It operates on 230 VAC single-phase or 230/400 VAC three-phase at 50 Hz, and carries a Class B energy meter with plus or minus 1% accuracy to ANSI C12.20¹⁰.

Solar integration: charging from your own roof with the Enphase App

Solar diversion is the feature independent guidance singles out first among what makes a smart charger worth having: it allows the charger to prioritise solar power for EV charging, minimising reliance on the grid¹¹. Enphase's implementation of that idea is green charging, which uses available surplus solar energy to charge the vehicle and works with compatible third-party solar systems as well as Enphase solar³.

The behaviour differs according to what the house has. Where the IQ EV Charger is paired with Enphase solar and home consumption monitoring, the system checks for surplus solar energy and, if it is more than 25% of the charger's rated capacity, the EV starts charging immediately¹². With the Self-Consumption profile and Green Charging with Battery Assist enabled, the system will supplement solar with energy from IQ Batteries so that charging can continue smoothly, until the system reaches the next 25% charging level¹². That is a deliberate trade: the car keeps charging through a cloud band, but the household battery is drawn down to do it.

Where the charger is not paired with Enphase solar or battery systems, there are two options for charging modes, Scheduled Charging and Manual Charging, both using grid modes¹². Manual charging runs the EV at 100% power level whenever plugged in, with whichever energy source is available¹². That is the standalone position: the charger still works, but the solar logic is absent.

Enphase states the charger works with any solar system, Enphase or other, adapting in real time to enable solar energy, even on cloudy days¹. The practical limit is that surplus-following depends on the charger seeing the home's import and export, which is why metering compatibility matters.

Smart Charging and Power Control Software: how overload protection works

The constraint that shapes every home charger installation is the size of the supply. Enphase's answer is dynamic load balancing, which automatically adjusts EV charging as electricity use in the home changes, helping prevent overloads and keep charging within the home's available electrical capacity³. The charger reduces its charging rate automatically to prevent overloading and main breaker tripping when household appliances reach the threshold limit¹³.

Smart Charging arrived in the Enphase App for homeowners using the IQ EV Charger 2 in April 2026¹⁴. It is reached from the EV charger status page, the EV charger settings page or the profile page¹⁴. Charging modes give three ways to decide how the EV charges when paired with an Enphase Energy System¹², and charging schedules apply to all homes with an IQ EV Charger, while the system profile setting applies only to homes with an Enphase Energy System¹⁵.

Metering is what makes the load control work. The IQ EV Charger 2 can use home metering data from compatible smart meters or CT-based metering solutions to enable dynamic load balancing and green charging, and in other markets installers can use compatible CT-based metering solutions³. The charger itself carries a built-in MID-certified meter with plus or minus 1% accuracy, with app-based and RFID access control¹.

Installation: why a licensed electrical contractor is recommended

Enphase's own installer page and the wider regulatory picture agree on one point: this is not a DIY job. Building regulations approval is always required when installing an EV home charger, and a competent and reputable installer should be used, with specific processes for notifying the local building control authority¹⁶. The recommendation is to use a reputable company and ensure the installer has the relevant qualifications¹⁶.

Independent guidance is firmer still. EV charger installation should always be done by a qualified and certified electrician¹⁸, and chargers should be installed by a registered electrician with experience in this type of installation¹⁹. Householders are advised to hire an electrician registered with a recognised certification body, such as NICEIC²⁰. Electricians registered on a Competent Person Scheme are deemed competent to self-certify their own work, saving householders time and money²⁰.

The technical responsibilities sit with the installer. To install EV chargers, competence in the IET Code of Practice for Electric Vehicle Charging is required²¹. That code highlights the installer's responsibility to assess the adequacy of supply capacity for the new EV load plus existing load, assess the adequacy of earthing, and notify the network operator once installation is completed²². Compatibility between the charger, solar system and any battery storage should be considered from the outset²³.

Enphase's own process runs through the Enphase Installer App, used to install and commission the charger²⁴. Commissioning through that app is a prerequisite before any third-party platform integration can be enabled²⁴. If a charger breaks, the guidance is not to attempt repair: it is a job for a professional electrician with the qualifications and certifications²⁰.

UK availability and power options

The IQ EV Charger 2 is the unit sold in the UK, in single-phase tethered form customised for UK smart charging regulations². Three-phase versions exist for homes with a three-phase supply, where independent guidance describes home charging typically at 11kW (3.7kW per phase) or higher²⁵. The charger provides both wired and wireless connectivity for flexibility⁸.

On price, Enphase publishes no UK list price for the charger or for a fitted installation, so figures are installer-quoted. For context on what a home charge point costs in general, official Northern Ireland guidance puts an EV charger at up to £1,000²⁶. That is a general figure, not an Enphase price, and it should be read as indicative only.

The charger is compatible with all Type 2 EVs sold in the UK¹. Charging current can be adjusted between 6 A and 32 A in the Enphase App⁶. A Cable and Connector Holster is available and is compatible with all versions of the IQ EV Charger 2⁶.

For households with an Enphase battery, the AC Battery is available via UK installers²⁷. That matters for the solar logic described above, because battery assist depends on an IQ Battery being present.

Partner integrations: Flipturn, E-Flux, Mobiflow and ChargeLab

Enphase's charger connects to third-party platforms through OCPP standards, robust APIs and local EMS interfaces, with either Enphase or the partner able to control and monitor the experience²⁸. Integration with an Energy Management System can be made locally over Modbus or similar, where the EMS owns the end user experience and Enphase can only monitor the charger²⁸.

Flipturn is one such partner. After integration, Flipturn can authenticate charging sessions, add or edit RFID cards, monitor data for all charging sessions and view historic consumption data²⁹. Registration runs through an activation form, and Flipturn verifies and confirms once the charger is connected²⁹. A restriction applies: authentication settings are blocked from the Enphase App, and owners need to use the Flipturn portal to manage RFID authentication settings²⁹. The charger must be online and unplugged before Enable is clicked²⁹.

E-Flux by Road works differently. Owners select it as a partner in the Enphase App, review access details and grant consent to share system data, after which a connection request is automatically sent to the E-Flux by Road platform²⁴. Mobiflow uses the charger's serial number as the charger ID on its platform³⁰. ChargeLab integration is enabled in the Enphase Enlighten App by selecting ChargeLab, reviewing access permissions and tapping Enable, with a registration request sent to the ChargeLab platform and an Active status shown if registration succeeds³¹. Commercial users contact ChargeLab directly to confirm dashboard access and charger registration³¹.

The pattern across all four is the same: the Enphase App retains start and stop, charging modes, real-time and historical consumption monitoring, charging reports and charger settings²⁹, but specific functions move to the partner platform once integration is switched on.

What an Enphase charger means for household energy independence

The independence case for an Enphase charger rests on the solar link. Green charging uses surplus solar to charge the car, and works with compatible third-party solar systems as well as Enphase solar³. When paired with an Enphase Energy System, charging can start from as little as 1.4 kW, so the car can absorb low surplus rather than waiting for a full-rate window¹. For a household with a roof array, that converts generation that would otherwise be exported into miles.

The dependence that remains is substantial and worth stating plainly. The charger is a grid-connected appliance: it draws from the grid whenever solar and battery cannot cover the load, and standalone homes get only Scheduled and Manual charging modes using grid power¹². Remote control, monitoring and reports run through the Enphase App, which means a dependence on home broadband, Enphase's cloud and a manufacturer's software¹. Partner integrations add a further platform to that chain, and in Flipturn's case move RFID authentication out of the Enphase App entirely²⁹.

Battery assist is a trade rather than a free gain: enabling it draws the household battery down to keep the car charging, until the system reaches the next 25% charging level¹². The bidirectional unit, when it arrives, would change the direction of flow, but it is expected to launch in late 2026 and is compatible only with ISO 15118-compliant EVs that support bidirectional power flow⁵. Until then, the household remains a consumer of grid electricity for any charging the roof cannot cover.
