GivEnergy EV Charger Not Working — Complete Diagnostic Guide
- All 5 configuration modes covered
- Full EV charger fault code reference
- Solar, tariff & scheduling 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.
I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.
When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.
Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them
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)
Contacted Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone
I've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues
Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.
After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.
Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.
Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.
I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration (their Trustpilot reviews don't lie!). So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.
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.
I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

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.
