Bought a house with a GivEnergy system
Good news: you've inherited the UK's most popular battery system with over 150,000 installations. GivEnergy systems are solid, well-engineered, and designed for UK homes. This guide covers everything you need to do as the new owner — from transferring your account to troubleshooting common issues.
After this guide, you'll know:
What you've inherited
A GivEnergy system typically includes several components working together. Understanding what you have helps you troubleshoot problems and know what to ask support about.
The inverter converts DC power from your panels to AC power for your home and the grid. GivEnergy's most common models are: Gen 1 (GE-AC-SP3648), Gen 2 (GE-AC-SP5000), and Gen 3 (GE-AC-SP5000-US). You may also have an All-in-One unit which combines the inverter and battery in one box. These are mounted in a garage, loft, or external wall.
A lithium battery that stores excess solar power during the day for use at night or during grid outages. Common models are Giv-Bat 8.2 (8.2 kWh), Giv-Bat 10.2 (10.2 kWh), or stacked multiples for larger capacity. It's usually wall-mounted near the inverter and includes integrated battery management. Batteries typically operate between 10%–90% state of charge to maximise lifespan.
A small device that enables remote monitoring via the GivEnergy cloud portal and app. Gen 1 and Gen 2 systems use a separate WiFi dongle; Gen 3 systems have built-in WiFi or use the GivHub. This is the device most likely to cause connectivity issues if your broadband has changed since installation.
Access at givenergy.cloud or the GivEnergy app. Shows real-time generation, battery state of charge, consumption, and export data. The portal frequently goes offline (GivEnergy server issues), but this does not mean your system is broken—it's still generating and exporting power normally.
Why GivEnergy?
GivEnergy is the most installed battery brand in the UK with over 150,000 systems deployed since 2016. Their hybrid inverters are popular because they're relatively affordable, support high export rates, and integrate well with time-of-use energy tariffs (Octopus Go, Agile, etc.). The company has faced support challenges recently and their knowledge base has been unreliable—which is why this independent guide exists.
Despite support difficulties, GivEnergy hardware remains solid and well-supported by the installer network and independent technicians.
Your first 5 steps as the new owner
Take these actions in order during your first week in the house. Each step takes 15–30 minutes and will secure your setup, confirm your system is working, and protect your investment.
Identify your inverter model and serial number
Find the GivEnergy inverter (usually mounted in a garage, loft, outbuilding, or external wall). Look at the label on the unit and note down: (1) Model number (e.g., GE-AC-SP5000), (2) Serial number (e.g., GE-AC-SP5000-XXXXXX). Keep these safe—you'll need them for warranty registration, support requests, and monitoring transfer.
Can't find your model? See How to Identify Your Inverter for detailed location and labeling guidance.
Transfer the monitoring account to your name
The GivEnergy portal (givenergy.cloud) is currently registered to the previous owner. You need to transfer it to your email address. Email support@givenergy.co.uk with:
GivEnergy typically responds within 5–10 working days. Once transferred, you can log in to givenergy.cloud and the app to monitor your system remotely.
Check the system is generating
On a sunny day, check that the inverter is producing power. You can verify this by: (1) Checking the inverter display for generation figures, (2) Looking at the export meter (smart meter or MID meter), or (3) Checking the GivEnergy app/portal if you already have access. A working system should show positive power generation between 9am–4pm on clear days.
If the inverter shows an error light or fault code, see System Not Generating Power for troubleshooting.
Check your export payment setup
Your energy supplier should be paying you for electricity you export to the grid. Check: (1) Your smart meter or MID meter is registered with your supplier, (2) Your export tariff is active (contact your supplier to confirm), (3) Your bank details are registered for receiving export payments. Most suppliers pay quarterly or monthly.

Register the warranty in your name
GivEnergy warranties transfer with the property. Email support@givenergy.co.uk with your inverter serial number and proof of property ownership to formally register the warranty under your name. They will confirm the warranty end date and any optional health checks available.
Warranty periods: Gen 1 systems (5 years), Gen 2 (10 years, extendable to 12), Gen 3 (12 years, with health checks at years 5, 8, 10).
See Warranty Check for detailed guidance on warranty coverage and claims.
Week 1 Checklist
GivEnergy monitoring — portal and app
Once you've transferred your account, the GivEnergy portal and app give you real-time visibility into your system's performance. But server reliability can be patchy—understanding the difference between a system fault and a portal outage is important.
Log in with your email and password. You'll see a dashboard showing: Live generation (W), Battery state of charge (%), Consumption (W), Export to grid (W), and Import from grid (W). Historical charts show daily, weekly, and monthly generation. This is your primary monitoring tool for understanding system performance.
Download on iOS or Android. Provides the same real-time and historical data as the portal. The app is useful for quick checks when you're away from home. Both the app and portal require your system to be connected to the internet via the WiFi dongle (Gen 1/2) or built-in WiFi (Gen 3).
Generation (W): Real-time power from your solar panels. Battery SoC (%): Battery charge level, 0–100%. Consumption (W): Your home's power usage. Export (W): Power sent to the grid (positive = exporting). Import (W): Power drawn from the grid (positive = importing). This data helps you understand energy flow and optimise consumption around peak generation times.
GivEnergy's portal frequently shows as offline or unreachable due to server issues, DNS problems, or maintenance. This is NOT a fault with your system. Your inverter and battery will continue to generate, store, and export power normally. The portal outage only affects remote monitoring—you won't be able to see live data, but the hardware is working fine. Check the local inverter display for confirmation. See Portal Offline for troubleshooting.
Monitoring Setup Guide
For detailed WiFi and monitoring configuration help, including troubleshooting connectivity issues and interpreting portal data, see GivEnergy Monitoring Setup.
WiFi and connectivity
Your GivEnergy system needs internet access to send monitoring data to the cloud and for you to access the portal remotely. The most common issue for new owners is that the WiFi dongle has lost connection after a broadband change.
A small USB device (about 2cm) connected to the inverter. It connects to your home WiFi network (2.4GHz only—not 5GHz) and uploads data to GivEnergy's servers. The dongle supports WPA2 security only (not WPA3). If your router has changed or the WiFi password has changed since the previous owner left, the dongle will be offline.
Newer Gen 3 systems have integrated WiFi and use a GivHub device for connectivity. This is more reliable than the older WiFi dongle. If your broadband details have changed, the GivHub will need to be reconfigured via the local WiFi network or a technician visit.
If your WiFi network or password is different from the previous owner's setup, the WiFi dongle won't connect. You need to: (1) Access the inverter's local WiFi AP (look for a network named something like "GE-XXXX"), (2) Connect your phone/laptop to it, (3) Configure the dongle to connect to your new WiFi network. Full instructions are in GivEnergy WiFi Setup.
2.4GHz band enabled: The WiFi dongle only works on 2.4GHz, not 5GHz or WiFi 6. Your router must have 2.4GHz enabled. WPA2 security: Use WPA2 or open WiFi (not WPA3-only). Good signal strength: WiFi signal should be at least −70 dBm at the inverter location. If your router is far from the inverter, consider a WiFi extender or relocating the router.
Offline After Moving In?
This is almost always a WiFi configuration issue, not a hardware fault. Start with GivEnergy WiFi Setup. If you're still stuck, book a diagnostic visit and a technician can reconfigure it for you (usually £75–£150).
Common issues on inherited GivEnergy systems
These are the issues we see most frequently on systems that have changed ownership. Most are straightforward to diagnose and fix.
The battery is fully discharged by morning and not charging overnight. Cause: Usually an incorrect charge schedule (set to "Do Not Charge" mode or charge time is too short). The previous owner may have configured the system to charge only during cheap hours. Check your tariff and reconfigure the charge schedule. See Battery Not Charging Overnight for steps.
The GivEnergy portal or app shows "offline" or you can't log in. Cause: Usually a GivEnergy server outage (common) or WiFi connectivity issue. Check the inverter display—if it shows normal data, the system is fine. Check Portal Offline for verification steps.
The inverter display shows a red light or fault code. Cause: Could be a communication error, WiFi issue, battery problem, or real fault. Check the inverter screen for the specific fault code. See Status Light Flashing Red for code interpretation and fixes.
The inverter shows "CAN communication fault" (usually error code 6006, 6007, or 6009). Cause: Communication cable between inverter and battery is loose or disconnected. This is a physical issue. See CAN Communication Fault for cable checking and reset steps.
During a power cut, the backup power to your home doesn't activate, or it's not running your chosen circuits. Cause: Usually EPS is disabled, circuits aren't configured, or backup loads exceed the inverter rating. See EPS Not Working for configuration guidance.
The inverter shows a firmware update notification or you suspect it's running outdated firmware. Cause: Usually the previous owner didn't keep the system updated. New firmware adds features and fixes bugs. See Firmware Issue for safe update steps (usually done via the portal).
The portal shows negative export (you're not earning export payments) or generation figures are negative. Cause: The CT clamp (current transformer) measuring grid flow is installed backwards. See CT Clamp Direction for checking and correcting orientation.
Your system can only export 1–3 kW instead of the expected 5+ kW, or it's capping at zero (not exporting at all). Cause: The export limit setting is configured lower than your DNO (Distribution Network Operator) allows. Most homes allow 3.68 kW or higher. See Export Limit Configuration to check and adjust.
GivEnergy warranty as a new owner
GivEnergy warranties transfer with the property, not the individual. As the new owner, you inherit the remaining coverage and can make claims. Understanding your warranty periods and how to claim is essential.
Gen 1 (2016–2019): 5-year inverter and battery warranty from installation. Gen 2 (2019–2022): 10-year standard (upgradeable to 12-year for a fee). Gen 3 (2022+): 12-year standard with optional health checks at years 5, 8, and 10. The warranty covers the equipment against manufacturing defects and capacity faults, not workmanship or misuse.
GivEnergy does not automatically know you've become the new owner. You must proactively contact them to register the transfer. Email support@givenergy.co.uk with: inverter serial number, proof of property ownership, and your details. They will confirm the warranty expiry date and add you as the registered owner. Keep their confirmation email—it's your proof of warranty for future claims.
If your inverter or battery fails within the warranty period, contact GivEnergy with: serial number, description of the fault, and the warranty confirmation email. They will troubleshoot remotely first. If it's a confirmed defect, they'll arrange repair or replacement, usually shipping a replacement unit to you or an installer. Turnaround is typically 2–4 weeks.
The warranty does not cover: workmanship or installation faults (unless the installer is still trading), damage from power surges or incorrect configuration, loss of data, routine maintenance, consumables, or cosmetic damage. If a failure is due to poor installation (e.g., wrong wiring), the installer is responsible, not GivEnergy.
GivEnergy has had documented support issues. If you don't receive a response within 10 working days, escalate to their management or contact an independent solar support provider. Warranty claim support services can review your situation and advise your options if GivEnergy is unresponsive. See Warranty Check for full details on your rights and escalation steps.
Check Your Warranty Status
Don't know when your warranty expires? Email GivEnergy (support@givenergy.co.uk) with your serial number and they'll confirm the expiry date. Alternatively, check your MCS certificate at mcscertified.com using your postcode—it shows the installation date, which determines warranty expiry.
Most UK homes have an MCS certificate registered with the Microgeneration Certification Scheme.
If GivEnergy support isn't responding
Let's address the elephant in the room: GivEnergy has experienced support difficulties in recent years. Longer response times, patchy knowledge base, and unreliable portal availability are documented issues. You're not alone if you're frustrated with their support.
Despite capacity issues, GivEnergy continues to handle warranty claims and account transfers. Their response time is longer than ideal (10–15 days vs. 5 days previously), but they typically do respond to documented support requests with serial numbers and proof of ownership. Email multiple times if needed; responses sometimes go to spam.
Solar Tech Support (STS) provides independent GivEnergy support precisely because the manufacturer's availability has been unreliable. We have no affiliation with GivEnergy and operate independently. Our guides, diagnostics, and support services exist to help homeowners get answers when they're stuck with manufacturer support.
If you're stuck waiting for GivEnergy or need expert diagnosis of a fault, STS provides: remote diagnostics (reviewing fault codes and system data), warranty claim advocacy (helping you escalate or dispute GivEnergy decisions), and on-site system checks (to identify faults and recommend repairs). We're not tied to GivEnergy and prioritise your interests.

Frequently asked questions
Yes. GivEnergy is the most popular UK battery brand with over 150,000 systems installed. Their hybrid inverters and Giv-Bat batteries are well-engineered, reliable, and designed specifically for UK homes with generous export limits and time-of-use tariff integration. The company has experienced support difficulties in recent years, which is why independent guides and support services exist. But the hardware itself is solid and widely trusted by installers and homeowners.
Email GivEnergy at support@givenergy.co.uk with: (1) Your inverter serial number, (2) Your new email address for the portal login, (3) Proof of property ownership (completion document, council tax bill, or mortgage statement), and (4) A photo of the inverter nameplate showing the serial number. They will process the transfer within 5–10 working days and send you new login credentials. Sometimes emails go to their spam folder, so follow up if you don't hear back after two weeks.
Probably not. GivEnergy's portal frequently goes offline due to server issues, database maintenance, or DNS problems. When the portal is down, you simply can't see your monitoring data remotely—but your system is still generating and exporting power normally. To confirm: (1) Check the inverter display for live generation figures, (2) Check your smart meter or export meter to see if power is flowing, (3) If both show activity, your system is fine. If you can't see any generation on the inverter display, then there's a real fault. See the common issues section above for troubleshooting specific fault codes.
Yes, absolutely. GivEnergy's warranty covers the equipment (inverter and battery), not the named individual. When you become the property owner, you inherit the remaining warranty. Most systems come with 10–12 years coverage depending on generation (Gen 1: 5 years, Gen 2: 10 years extendable to 12, Gen 3: 12 years standard). You must notify GivEnergy in writing to formally transfer the warranty to your name, but your ownership of the property and equipment gives you clear legal rights to the coverage. Always get written confirmation of the warranty expiry date from GivEnergy for your records.
No, you can switch to any energy supplier you like. However, GivEnergy systems work exceptionally well with time-of-use (ToU) tariffs like Octopus Go, Octopus Agile, or similar because the system's charge schedule can be aligned with cheap-rate periods (e.g., 11pm–7am on Go). This maximises battery charging during cheap hours and exporting during expensive peak hours, optimising financial returns. If you switch to a fixed-rate supplier, the system still works but you lose some of this optimisation benefit. We recommend keeping a ToU tariff, but your system is fully compatible with any standard electricity supplier.
Yes, absolutely. Your GivEnergy inverter and battery are hardware devices that work independently of the company. If GivEnergy ceased operations tomorrow, your system would continue to generate power from the panels, charge and discharge the battery, and export surplus power to the grid. You would lose access to the cloud monitoring portal and app, but the core functionality is completely independent. The system can be locally configured via the WiFi interface if needed. You are not reliant on GivEnergy remaining in business for your system to function or for you to have a working solar installation.
