Following the storm my givenergy system was effectively useless. I contacted STS after seeing other reviews and recommendations and they delivered. My system was a challenging one, but is now back working as it was - this was all done remotely by them using their own software and expertise. Great service, thank you!
GivEnergy EV Charger Not Working — Complete Diagnostic Guide
- All 5 configuration modes covered
- Both GivEnergy fault code lists, labelled by source
- Solar, tariff & scheduling conflicts
We diagnose GivEnergy EV charger issues remotely — checking configuration mode, fault logs, and solar integration. Most issues are identified and resolved in a single session without a call-out. WiFi isn't remote work: the offline checks on this page are free to follow, and if the charger needs reconnecting to your WiFi, we can set it up on site, from £195.
Ron is incredibly knowledgeable about solar installs in general but knows givenergy products inside out and the key personnel that worked there from the start to the end. My problem was spurious in its nature but Ron spotted it straight away when he understood the installation details. In essence the installers didn’t fit the correct trip switch. He also gave me hope that in the future hardware repairs could be possible but it’s still early days. This guy really is in the know and keen to sucas a business If you need help don’t hesitate
Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)
Amazing! I was having trouble with a flat GivEnergy battery and solar panels not working. I contacted through WhatsApp and we managed to get it all sorted within a couple of days! Super fast service. I can’t thank you enough for your help when my installer didn’t want to know and GivEnergy has gone in to administration! I know where to go if anything happens again!
Ron responded very promptly regarding my GivEnergy battery issue, his knowledgeable diagnosis was spot on and resolved the issue on first attempt. Would recommend to any and all.
This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing. If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.
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 (control pilot) pin is one of the most common causes of an E007 fault, where the car and charger can't talk. GivEnergy's manual has a CP fault in its numbered list too: 11, CP Voltage Abnormal.
The tamper switch is a safety interlock inside the charger housing. If the front cover is not fully closed and sealed, the switch triggers a tamper fault (E0013 in GivEnergy's Troubleshooting Guide, 12 in its manual) and stops all charging. Check the app or portal for a tamper alert. If there is one, the cover needs to be fully reseated. This is a quick installer job: don't open the charger yourself.
The lights on the front are the quickest guide to what the charger is doing. GivEnergy's own documents disagree on what the colours mean, so both lists are below, each labelled with its source.
GivEnergy's own documents disagree
The two lists give green and blue different meanings. Our tip: look at the charger while you check the app. If the app says the car is charging, the colour you see tells you which list your charger follows. Yellow appears only in the manual. Red means a fault on both lists, so note any fault code in the app and look it up in the tables further down this page.
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.
The GIV-EV-7.2 supports both 2.4GHz and 5GHz, unlike the inverter WiFi dongles, so a dual-band router or band steering is not in itself a blocker. What matters is signal strength where the charger is mounted, usually on an outside wall. Stand at the charger with a phone and check the bars. If the signal is marginal, 2.4GHz normally carries further through masonry than 5GHz, so pinning the charger to a 2.4GHz SSID can help. A LAN cable is the most reliable option of all.
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. If it still won't connect, we set it up on site, from £195: we connect it to your WiFi, set up your router, including a separate 2.4 GHz network if it needs one, and check it's reporting. If the signal doesn't reach, a WiFi extender is an extra £75, and we carry them with us.
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.
Open the EV charger settings in the GivEnergy app (the charger always needs you to log in), or at givenergy.cloud → EV Charger → Settings if you have GivEnergy Premium. 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
GivEnergy published two different fault code lists for its EV charger, and they disagree. What your charger or app shows tells you which list applies. A code starting with E (E001 to E0026) is from the EV Charger Troubleshooting Guide. A plain number from 11 to 26 is from the EV Charger Installation Manual.
GivEnergy has not published how the two lists match up, and the same number means different things (E0013 is a tamper fault in the guide; 13 is under voltage in the manual). Read each code against its own list.
List 1: codes starting with E
Source: GivEnergy EV Charger Troubleshooting Guide (GivEnergy support article). Names are as GivEnergy gives them.
| Code | GivEnergy's name | What it means and what to do |
|---|---|---|
| E001 | Over Current Fault | The car is asking for more current than allowed. GivEnergy says this could be a faulty onboard charger in the car or a wrongly set charge limit. Check the car's charging settings, then ask your installer. |
| E002 | Under Voltage Fault | Grid voltage too low. Note when it happens and ask an electrician or your network operator (DNO) to check the supply. |
| E003 | Over Voltage Fault | Grid voltage too high. GivEnergy says this may happen during solar export, and points to CT direction, inverter settings or the DNO supply. |
| E004 | Earth Fault | Earth connection lost, or leakage detected. This is a safety fault: do not keep resetting it. An electrician should test the earth, bonding and insulation. |
| E005 | Over Temperature Fault | Charger too hot. GivEnergy lists high ambient temperature, direct sunlight, poor airflow or a faulty temperature sensor. Make sure nothing blocks the air around the unit. |
| E006 | Relay Fault | The charger could not open or close its internal relay safely. Usually a hardware fault. GivEnergy Ltd is in administration, so there is no manufacturer RMA route. Ask your original installer if they are still trading, or have it inspected to see whether it is worth repairing. |
| E007 | CP (Control Pilot) Fault | Communication with the car failed. GivEnergy says the usual causes are a poor cable connection, a damaged CP pin or an incompatible car. Check the plug for dirt, damage or bent pins. If another car charges on it, the problem is likely with your car. |
| E008 | Plug Lock Fault (for socketed units only) | The lock that holds the plug in has failed. Push the plug fully home and try again. GivEnergy's manual describes the GIV-EV-7.2 as tethered (fixed cable), so in our reading this code should only appear on a socketed unit. |
| E009 | Communication Error with Internal Module | A fault between boards inside the charger. GivEnergy says it may need inspection or return. With GivEnergy Ltd in administration, ask your installer or have it inspected. |
| E0010 | CT Comms Fault (in CT Meter Mode) | The charger cannot see its CT meter, or the meter is wired wrongly. Only applies in CT Meter mode, so check the mode in the app first. The RS485 wiring and CT direction are installer checks. |
| E0011 | Internet / Cloud Communication Failure | The charger cannot reach GivEnergy's servers. Check the WiFi or LAN connection and the router. The guide names port 7655 here; elsewhere it says the charger uses outbound port 7654 or 7655 (only one of them), so make sure both are open. |
| E0012 | Grid Code Error | The charger has lost or rejected its grid code settings. GivEnergy says this usually follows a firmware update or a power cut, and the settings may need resetting and confirming again. Ask your installer or contact us. |
| E0013 | Tamper Fault | Lid not seated correctly, or tamper switch out of line. Stops all charging for safety. Your installer reseats the cover and switch. Don't open the charger yourself. |
| E0014 | Internal Memory Error / EEPROM Fault | The charger cannot read or write its internal memory. Needs inspection. Contact your original installer if they are still trading. GivEnergy Ltd is in administration, so there is no manufacturer warranty route. |
| E0026 | Over Voltage Trigger | GivEnergy says to check the charger's voltage graph in the app or portal for spikes over 253 V. If you see them, ask an electrician or your DNO to check the supply. |
The guide says many faults clear themselves once the cause is gone, for example after unplugging and replugging the car or a restart. It says faults usually come with a flashing red light and show in the app, and that persistent faults such as E006, E0013 and E0014 often need your installer.
List 2: numbered codes 11 to 26
Source: GivEnergy EV Charger Installation Manual (December 2025 edition). Names are as GivEnergy gives them. The manual has no code 20.
| Code | GivEnergy's name | What it means and what to do |
|---|---|---|
| 11 | CP Voltage Abnormal | CP (control pilot) voltage out of range. The CP line is how the car and charger talk. Check the plug for dirt, damage or bent pins. |
| 12 | Emergency Stop Status (Tamper Switch) | Tamper switch released. The charger stops charging until your installer reseats the cover and switch. Don't open the charger yourself. |
| 13 | Under Voltage | Grid voltage too low: under 161 V for more than 5 seconds. Ask an electrician or your DNO to check the supply. |
| 14 | Over Voltage | Grid voltage too high: over 270 V for more than 5 seconds. Ask an electrician or your DNO to check the supply. |
| 15 | Over Temperature | Main board too hot: over 80°C. Check for direct sun or blocked airflow around the unit. |
| 16 | Electric Meter Fault | The manual gives no detail. In our reading its start-up beep check is related: one beep means no meter or meter comms detected, two beeps means the meter is seen. Meter wiring is an installer check. |
| 17 | Leakage Protection | AC leakage over 20 mA, or DC leakage over 6 mA, detected. This is a safety fault: do not keep resetting it. Call an electrician. |
| 18 | Output Shortage | Charging current 10 A higher than the maximum output current. Ask your installer. |
| 19 | Over current | Charging current 10% higher than the maximum output current. Check the car's charge settings, then ask your installer. |
| 21 | EV Response Timeout | The manual gives no detail. Unplug and replug the car, then restart the charger. |
| 22 | EV Not Supported | The manual gives no detail. If another car charges on it, the problem is likely with your car. |
| 23 | Relay Sticking | AC relay not working. A hardware fault that needs inspection. |
| 24 | Internal RCD Failure | The built-in Type B RCD is not working. This is a safety fault: stop using the charger and call an electrician. |
| 25 | Ground Fault | The manual gives the same description as code 24 (internal Type B RCD not working). Treat it as a safety fault and call an electrician. |
| 26 | PEN Leakage Protection Activated | The manual lists two conditions: voltage between line and neutral above 253 V or below 207 V; current detected on the earth conductor. This is a safety fault: call an electrician, and your DNO if the supply voltage is the cause. |
For any code on this list, the manual's first steps are: check the charger for damage and that the front cover is secure; check the cable and plug for damage, water or debris, and unplug and replug the car; restart the charger; then contact your installer. The manual's further checks (AC wiring, supply voltage, earth leakage, earth continuity and the import limit) are for an electrician.
Codes in red on either list are safety or hardware faults that usually need an electrician or specialist. Never open the charger yourself. The charger's original 3-year warranty was with GivEnergy Ltd, which entered administration on 9 April 2026, so a direct claim against the manufacturer is unlikely to succeed. Our GivEnergy warranty page sets out the routes that may still be open.
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 →Axle Energy grid events and EV charging
If you have joined Axle Energy's grid-services scheme (GivEnergy used to run its own, called GivBack), Axle's instruction takes priority over your inverter and battery settings during an event, and it exports from the battery at full power. Axle publishes no fixed time of day for events, and how a GivEnergy EV charger behaves in Solar Only or CT Meter mode during one isn't documented, so if the charger misbehaves around an event, check your Axle account first. See our Axle Energy guide.
When to call STS — beyond the self-help checks
