Brilliant support to get my solar battery working again. I didn’t expect help on a Saturday but Ron answered the phone, listened and sent me the information I needed to get it going, answered questions etc. A brilliant service I’d happily recommend.
Big thanks to Ron. He was incredibly patient and helpful over the phone, taking the time to walk myself and the installer through every troubleshooting step. Through lots of testing he figured out the issue was definitely a hardware issue, which allows us to consider our next steps. Support fees are clear and they operate a “no fix no fee” policy. It is rare to find that kind of honesty combined with dedicated phone support nowadays. I highly recommend Ron, if you need help with your solar system don’t hesitate to give him a call.
My GivEnergy hybrid inverter + battery system had worked faultlessly for 3 years when it suddenly stopped charging and discharging the battery. On contacting my supplier, who had used a sub-contractor for the installation work, I was provided with an email address at GivEnergy but, as it turned out, this is only for GivEnergy Software who are not able to assist. A Google search led to the Solar Tech Support web site, which contains a wealth of helpful information. I requested a remote solar diagnostic, and after providing Ron access to my inverter, he was able to identify and fix the problem within minutes. I am very impressed by Ron’s expertise and knowledge, which included useful information on the current state of GivEnergy Ltd. I would thoroughly recommend Solar Tech Support.
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. 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.
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.
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.
The GivEnergy app is your main control point for charge schedules, system modes and daily monitoring. This guide walks through linking your system, setting up charge times, reading your dashboard data and fixing the most common app issues — including the dreaded "no data" blank screen.
Download the app, register and pair your inverter serial number to see live data
Set off-peak charging times from your phone — including the midnight boundary rule
Understand Eco, Timed Charge and Timed Discharge — and which to use when
App showing blank dashboard or dashes? Here's exactly how to restore the data feed
App availability: The GivEnergy app is available on both iOS (App Store) and Android (Google Play). Search GivEnergy — the icon is a green battery. You'll need your installer's registered email address to create an account, or ask your installer to invite you as a secondary user.
Once the app is installed, you need to link your GivEnergy inverter to your account. The app communicates with your inverter via the GivEnergy cloud portal — so your inverter's WiFi dongle must be online.
Search GivEnergy in the App Store or Google Play and install it. Open the app and tap Create Account.
Use the same email address your installer registered the system under. If you're unsure, check any documentation from your installation day or ask your installer. Alternatively, ask your installer to add you as a secondary user from their portal account.
Tap Add Device and enter your inverter serial number — usually a 10-digit number starting with CE or SA printed on the inverter label or in your installation paperwork.
The main dashboard should show solar generation (PV), battery SoC%, home consumption and grid import/export as live figures. If all values show as dashes or zero, see the No Data fix section below.
Total kilowatts currently being generated by your solar panels. Should track sunlight — zero at night, peaks around midday on sunny days.
Battery State of Charge as a percentage. The minimum usable level is set by your Reserve SoC setting — the battery won't discharge below this.
Total household consumption right now. This includes everything switched on — appliances, EV charger, heating. Higher than expected? Check for high-draw devices left running.
Positive = importing from grid (paying). Negative = exporting to grid (earning SEG or export rate). Near-zero means the system is running self-sufficiently.
A charge schedule tells the inverter when to pull cheap overnight electricity from the grid to fill the battery. This is the most common setting to configure — and one of the most common sources of confusion. Follow these steps carefully.
This opens the battery detail view. Scroll down to Charge Schedule and tap it.
Use the time picker to enter your off-peak start and end time. For Octopus Go (23:30–05:30) or Economy 7 (typically 00:30–07:30). Important: GivEnergy schedules cannot cross midnight. See the midnight rule below.
This is the SoC% the battery will charge to during the slot. Most households set this to 100% in winter and 50–80% in summer when there's more solar available. Setting it lower than your current SoC won't cause any charging.
The app sends the schedule to the inverter via the cloud portal. It takes around 60 seconds to apply. You can verify it worked by going to Settings > Charge Timers and checking the saved values match what you entered.
The midnight boundary rule — critical for Octopus Go users
GivEnergy schedules cannot cross midnight in a single slot. If your off-peak window runs from 23:30 to 05:30, you must split it into two separate charge slots:
This will not work
Slot 1: 23:30 → 05:30
The inverter ignores slots that cross midnight
✓ Correct — two slots
Slot 1: 23:30 → 23:59
Slot 2: 00:00 → 05:30
Both slots set to 100% target SoC
For full details on tariff-specific schedule settings including Octopus Go, Economy 7 and Go Faster, see the GivEnergy Charge Schedule configuration guide.
The system mode controls how the inverter prioritises solar, battery and grid. You change this in the app under Settings > System Mode. The wrong mode is one of the most common reasons a battery appears not to be working correctly.
Solar charges battery first, battery powers home. Grid only used when both are insufficient. No grid charging.
Best for: summer with plenty of solar and flat-rate tariff. Not suitable for overnight grid charging.
Battery charges from grid during scheduled slots (your off-peak window). Solar still charges during the day. Grid used outside slots only if needed.
Best for: most UK households on Octopus Go, Economy 7 or similar two-rate tariff.
Battery discharges to power home or export to grid during scheduled slots. Useful for peak-rate export (Agile, Flux peak windows).
Best for: advanced users on variable-rate tariffs maximising export earnings. Needs careful schedule setup.
Good for most households — keeps a small reserve for grid outages without holding back too much usable capacity.
Useful in cold weather when battery capacity drops, or if you have critical loads (medical equipment, home office) needing overnight cover.
Only set this high if explicitly recommended. A high reserve means the battery barely discharges, which often looks like a fault when it isn't.
The app's history and analytics screens help you understand how well your system is performing. Knowing what "normal" looks like makes it much easier to spot problems early.
Shows energy flow for a single day broken into solar generated, battery charged, battery discharged, grid imported and grid exported (kWh). A healthy day typically shows solar charging the battery during daylight, battery powering the home in the evening, with minimal grid import.
Watch for: Grid import during peak afternoon hours when the sun should be producing — this could mean shading, a panel fault or an inverter issue.
The SoC graph over 24 hours should show a clear rise during your overnight charge window, a gradual fall through morning and evening use, and a mid-day bump from solar. If the overnight charge didn't happen, the line will be flat — check your charge schedule settings and system mode.
Watch for: SoC dropping in a straight vertical line — this often indicates a calibration issue rather than actual rapid discharge. See our battery calibration guide.
Accessible from Settings > Event Log (or the portal web interface). Logs every system event — firmware updates, connectivity drops, charge/discharge starts and any error codes. If something odd happened at a specific time, the event log usually explains it.
Watch for: Repeated connectivity drop events (dongle losing WiFi), or fault codes prefixed with E — these should be investigated. CAN communication faults appear here — see our CAN fault guide if you see CAN errors.
Push notifications let you know when something needs attention — without having to open the app every day. Go to Settings > Notifications to configure these.
Notifies you when SoC drops below a threshold you set (e.g. 15%). Useful in winter when a missed overnight charge leaves you short for the next day.
Alerts you if the system loses connection to the portal for more than a set period. Often the first sign of a WiFi dongle issue.
GivEnergy releases firmware updates that improve performance and fix bugs. Knowing when one is available lets you review release notes before approving the update.
A daily digest of generation, consumption and grid usage. Helpful when first learning the system, but many users disable it once they're confident everything's working correctly.
The GivEnergy app relies on your WiFi dongle maintaining a connection to the portal. When this link drops, the app shows dashes, zeros or a blank dashboard. The inverter is almost always still working — you're just not seeing it. Follow these steps in order.
The WiFi dongle (plugged into the side of the inverter) has an LED indicator. Solid green = connected. Flashing or red/off = lost connection. If offline, proceed to step 2.
Gently pull the dongle out of the inverter's USB/communications port, wait 30 seconds, and re-insert it. Wait 2 minutes for it to reconnect. Check the app — data should resume within 5 minutes.
If your router was replaced, reset or changed, the dongle will still be trying to connect to the old network. You'll need to re-pair the dongle to the new network using the GivEnergy app's WiFi setup section under Settings > WiFi Configuration.
The portal requires outbound connections on port 443 (HTTPS). Some routers with parental controls or strict outbound filtering can block this. Temporarily disable any firewall rules and retest. Business broadband connections sometimes block outbound HTTPS by default.
If the dongle is showing as connected but the portal still shows no data, a full system restart often resolves it. The inverter resets the portal communication session on startup. See our GivEnergy full restart guide for the correct shutdown and restart sequence.
Occasionally the GivEnergy portal itself experiences outages. Check GivEnergy's status page or community forum to confirm whether the issue is on their side before spending time diagnosing locally.
Still no data after all these steps?
If the dongle LED is solid green, the router firewall is clear and a full restart didn't resolve it, the WiFi dongle itself may have developed a fault. GivEnergy dongles can be replaced — contact your installer or STS for a replacement dongle. We can diagnose remotely and arrange a swap if needed.
Some app issues have a clear DIY fix; others mean something deeper is wrong with the inverter, the BMS, or the smart-tariff API. Use this matrix to decide.
App shows persistent fault codes you don't recognise.
Battery SoC reading is clearly wrong (e.g. shows full but system imports all night).
Data dropout happens daily and the steps above don't fix it.
Settings keep resetting to defaults after you save them.
You're on a smart tariff and unsure whether to revoke API access.
Setting up new slots in the app — covered in Step 2 above.
Lowering or raising the reserve floor as battery capacity changes.
Settings > System Mode — instant switch with the portal.
Pull-and-replace, follow the No Data Fix steps.
Settings > Event Log shows everything the system has logged.
Whether it's a persistent blank dashboard, settings you can't get to stick, or an SoC reading that just doesn't add up — our engineers are used to diagnosing GivEnergy remotely. Fill in a few details and we'll come back to you.
I’ve worked on hundreds of GivEnergy systems and know the kit inside out. If yours is playing up, my promise is simple — no fix, no fee: just £75 if we fix it, free if we don’t.
