GivEnergy EV Charger Not Working — Complete Diagnostic Guide
Your GivEnergy EV charger is offline, won't charge, shows a fault code, or charges too slowly. This guide covers every failure mode in order of likelihood — from tamper switches and WiFi configuration through to fault code lookup and solar integration conflicts.
We diagnose GivEnergy EV charger issues remotely — checking network connectivity, configuration mode, fault logs, and solar integration. Most issues are identified and resolved in a single session without a call-out.

Safety and visual checks
EV chargers are connected to high-voltage systems. Work through these checks before touching anything else — many faults are resolved at this stage.
Run through in order
Before handling the charger or cable, turn off the dedicated EV charger breaker. Confirm no RCD or MCB has tripped — if it has, do not simply reset without investigating the cause.
Check both ends of the charging cable for damage, rust, bent pins, or debris in the socket. A dirty or damaged CP pin is one of the most common causes of an E007 fault (car won't communicate with charger).
The tamper switch is a safety interlock inside the charger housing. If the front cover is not fully closed and sealed, the switch triggers an E0013 fault and shuts down all charging. Check the portal — if it shows "Tamper Triggered," the cover needs to be fully reseated. This is an easy installer fix.
The front LED gives the most immediate indication of state. Use the table below to direct your troubleshooting.
Charger ready and waiting. Vehicle not connected or not requesting charge.
Actively charging. Normal operating state.
Vehicle connected but not yet requesting charge — check vehicle settings.
Fault, tamper alert, or network connection lost. Check fault codes in app.
Charger showing offline in the app or portal
A GivEnergy EV charger showing as offline in the app does not mean it has failed — most offline states are connectivity issues, not hardware faults.
Diagnose in order
Turn off at consumer unit. Wait 30 seconds. Turn back on. Allow 5 minutes for the charger to reconnect. This resolves the majority of sudden offline states after power cuts or broadband restarts.
GivEnergy EV chargers require access to a 2.4GHz WiFi band. If your router only broadcasts 5GHz, or uses band steering that pushes devices to 5GHz, the charger cannot connect. Log into your router admin page and ensure a 2.4GHz SSID is available and accessible from where the charger is installed.
The WiFi network name (SSID) must not contain spaces or special characters. A router renamed to something like "Smith's WiFi 2.4" can prevent the charger from connecting. Rename the SSID to remove special characters and re-enter credentials in the app.
GivEnergy chargers communicate over port 7654 or 7655 (only one is used — check both). Some routers or ISP-managed firewalls block outbound traffic on non-standard ports. Log into your router and create an outbound allow rule for both ports. Virgin Media Hub and BT Smart Hub firewalls are common offenders.
GivEnergy EV chargers are not compatible with Eero 6E mesh extenders. Even if the charger connects to WiFi, Eero's network isolation can prevent it from communicating with GivEnergy servers. Solutions: connect via LAN cable instead, set up a 2.4GHz-only guest SSID on the Eero, or contact Eero support to enable the appropriate firewall rules.
To rule out home network issues completely, temporarily connect the charger to a mobile hotspot. If it comes online via hotspot but not via home WiFi, the problem is your router configuration, not the charger itself.
Static IP reservation helps stability
If your router reassigns IP addresses via DHCP, the charger can get a different IP after a reboot, causing intermittent drops. Log into your router admin page and create a static IP reservation for the charger's MAC address. This prevents IP conflicts and improves long-term stability.
Charger online but car won't charge
The charger is online and the vehicle is plugged in, but charging doesn't start. There are three distinct failure paths here — vehicle-side, charger configuration, and CP signal issues.
The car has its own charge schedule enabled, a charge limit set, or smart charging active via an app. The charger sends the signal — the car refuses it.
Check vehicle app first
Wrong config mode selected — particularly Solar Only mode when there's no surplus export, or CT Meter mode without a CT installed.
Check portal settings
A damaged cable, dirty CP pin, or incompatible vehicle creates a CP fault. The charger shows 53% duty cycle — meaning the car is not requesting charge.
Swap cable to test
Step-by-step resolution
Open the vehicle app (Tesla, Volkswagen We Connect, MG iSmart, etc.) and disable any active charge schedule. Also check the infotainment screen for a "Charge Later" or "Scheduled Charging" setting. Test an immediate manual charge once this is off.
Go to givenergy.cloud → EV Charger → Settings. Confirm the mode is set to what was configured at installation. If set to Solar Only, the charger will not start unless your system is actively exporting solar surplus — it will not charge from the grid. Change to the appropriate mode for testing.
If your energy provider (Octopus, OVO, etc.) is connected via API and managing your GivEnergy system, it may be overriding the charger's behaviour. Temporarily disable the third-party integration and test manual charging. If it works, the conflict is in the smart tariff control — see our smart tariff lockout guide.
If the problem persists after steps 1–3, try a different Type 2 charging cable. CP pin issues are sometimes invisible on inspection but show up on substitution. A cable rated below 32A also limits available current, which can cause some vehicles to reject the charge offer.
Charging slower than expected
Slow charging is most often the vehicle throttling the rate, not a charger fault. Work through these causes before assuming a hardware problem.
Check CT clamp direction if on Solar Only mode
If your charger is set to charge from solar surplus and it's charging very slowly even in bright sunshine, the CT clamp may be installed backwards. An inverted clamp makes the system think you're importing rather than exporting, so the Solar Only threshold is never met. See our CT clamp direction guide for diagnosis steps.
The five GivEnergy EV charger configuration modes
The configuration mode determines how the charger sources power and integrates with your solar system. A wrong mode at commissioning is one of the most common causes of persistent charging failures that are never traced back to configuration.
Grid power and internet only. No solar integration. Basic scheduling available via app. Correct mode for properties with no solar or battery.
Site has third-party solar but no GivEnergy inverter. Manual control only — no direct integration with the solar system.
Connected to a CT meter via wired comms cable. Enables dynamic load balancing and solar export detection. Requires physical CT meter wiring.
Communicates with GivEnergy inverter over the cloud. Full dynamic control. No physical cable needed. Requires both devices registered under the same GivEnergy account.
Best for most GivEnergy solar setupsHardwired to GivEnergy inverter via comms cable. Real-time data exchange without internet dependency. Used where cloud connectivity is unreliable.
Wrong mode is hard to spot
A charger in CT Meter mode without a CT installed will show as online in the portal but will never charge, because it's waiting for a meter signal that doesn't exist. A charger in Inverter Control Cloud mode but not registered on the same account as the inverter will behave similarly. If the charger has never worked correctly since installation, check the config mode before anything else.
GivEnergy EV charger fault codes
Fault codes appear in the GivEnergy app and portal when the charger detects a problem. Most faults self-clear once the underlying issue is fixed. Persistent faults marked in red require installer involvement.
| Code | Description | Common causes & action |
|---|---|---|
| E001 | Over Current Fault | Car requesting more current than the charger allows. May be a faulty vehicle onboard charger or misconfigured charge limit. Contact installer. |
| E002 | Under Voltage | Grid voltage too low at the site. Check supply with a meter or contact your DNO. |
| E003 | Over Voltage | Grid voltage too high — can occur during peak solar export. Check CT clamp direction and inverter export limit settings. |
| E004 | Earth Fault | Earth connection lost or leakage detected. Do not reset without investigation. Contact a qualified electrician — this is a safety fault. |
| E005 | Over Temperature | Charger overheating. Usually direct sunlight, poor airflow, or high ambient temperature. Ensure adequate ventilation around the unit. |
| E006 | Relay Fault | Internal relay failed to close or open. Often a hardware fault — requires installer inspection or RMA. |
| E007 | CP (Control Pilot) Fault | EV communication failed. Try a different cable. If fault persists across cables, may be vehicle or charger hardware. |
| E0011 | Cloud Communication Failure | Charger can't reach GivEnergy servers. Check WiFi/LAN connection and ensure port 7655 is not blocked by router firewall. |
| E0013 | Tamper Fault | Front cover not fully sealed. Installer must reseat tamper switch. Charger will not operate until resolved. |
| E0014 | Internal Memory Error | EEPROM fault — requires inspection. Contact installer or GivEnergy support. |
| E0026 | Over Voltage Trigger | Voltage spiking over 253V. Check EVC voltage graph in portal. May need DNO investigation or export limit adjustment. |
Red codes (E004, E006, E0013, E0014) typically do not self-clear and require installer or specialist involvement.
Schedule and tariff conflicts
Multiple scheduling systems controlling the same charger simultaneously is one of the most common causes of intermittent failures that are impossible to trace without understanding the control hierarchy.
If both the vehicle and the GivEnergy app have charge schedules active, they may conflict. A vehicle set to charge at 02:00 will refuse a signal from the GivEnergy charger to start at 23:30. Always disable one schedule entirely for testing.
Fix: disable vehicle schedule, use GivEnergy app only
Octopus Intelligent and similar tariffs send control signals to your GivEnergy system via API. These override manually set schedules. If the charger starts at unexpected times or fails to start when scheduled, check whether an Octopus or third-party API is connected.
Smart tariff lockout guide →GivBack programme and EV charging
If you're enrolled in the GivLink (GivBack) virtual power plant programme, the system may temporarily override your inverter and battery schedule during grid events. During grid events (typically 4–8pm), you may see reduced charge rates in Solar Only or CT Meter modes. See our GivLink guide for details.
When to call STS — beyond the self-help checks
The steps above resolve the majority of EV charger problems. If the charger still isn't working, these are the situations that need specialist attention.

GivEnergy EV charger — common questions answered
The most common causes are: weak or incompatible WiFi (2.4GHz required, Eero 6E mesh incompatible), the tamper switch not seating properly after the cover was opened, a router firewall blocking port 7654 or 7655, or an IP address conflict. Try a 30-second power cycle first — this resolves most sudden offline states.
Check the vehicle app first — EVs including MG4, VW ID series, and Tesla have built-in schedules that override external chargers. Then check the configuration mode in the portal: Solar Only mode won't charge from grid, and CT Meter mode without a CT installed won't work. If both are correct, try disabling any third-party smart tariff API connection.
No — 80% charge limits are set by the vehicle itself, not the charger. Most EVs including Tesla, MG4, and Volkswagen ID series default to an 80% charge limit to protect long-term battery health. Open your vehicle app and increase the charge limit if you need a full charge.
Yes, but use only one control system at a time. Octopus Intelligent sends automated control signals to your GivEnergy system via API. Running the GivEnergy app schedule and Octopus Intelligent simultaneously causes conflicting instructions. Choose one as your primary control system and disable scheduling in the other.
An E0013 means the tamper switch inside the charger has been triggered — this happens when the front cover is not fully seated and sealed. The charger disables all charging as a safety measure until the tamper switch is properly reset. Your original installer can reseat it in minutes. If your installer is no longer available, contact us — this is a straightforward fix we can guide through remotely.
