GivEnergy Export Limit — What to Set, Why It Resets & G98 vs G99
- Most UK single-phase systems: 3,680W
- Firmware resets this to 0W silently
- G98 and G99 conditions explained
Your correct export limit is determined by your DNO connection conditions — not by what's convenient or what the installer set at commissioning. We can check your MCS documentation, confirm your G98/G99 status, and set the correct value remotely.

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!

What the export limit setting does
The export limit tells the GivEnergy inverter the maximum power it is allowed to push onto the grid at any moment. The inverter actively enforces this — if solar generation minus household consumption would exceed the limit, the inverter throttles down output rather than exporting above it.
No export permitted
All generation is consumed by the house or stored in the battery. Any surplus above what the house and battery can absorb is curtailed — the panels back off and that energy is lost. Required for some DNO conditions and leasehold properties.
Standard single-phase
The G98 limit for single-phase UK connections. Correct for most residential installations. Excess generation above household consumption and battery capacity is exported at up to 3.68kW.
Custom G99 limit
If your DNO issued a G99 approval with a specific export cap — e.g. 1,500W or 2,000W — this figure takes precedence. Your connection agreement will state the exact value. Never exceed your DNO-approved limit.
What export limit should you set?
The correct value is determined by your DNO connection conditions — not by what your installer set, not by what seems reasonable, and not by the inverter's maximum capability. Check your documents before changing this setting.
G98 vs G99 — which applies to your installation?
G98 and G99 are the UK grid connection standards that govern how solar and battery systems connect to the distribution network. Which one applies determines your maximum export level and what the DNO must be told.
Up to 3.68kW single-phase export
Most UK residential solar installations fall under G98. The installer notifies the DNO that the system has been connected — no prior approval is required. The DNO cannot refuse connection under G98.
Larger systems or higher export
G99 applies to larger systems, three-phase connections, or any installation the DNO determines needs assessment. The DNO reviews the application and may impose conditions — including a specific export cap — before issuing approval.
Firmware update reset the export limit to 0W
GivEnergy firmware updates regularly reset the export limit to 0W. When this happens, the system continues to generate and the battery continues to charge and discharge — but nothing is exported to the grid. On an export tariff, this means you stop earning export payments immediately, silently, until someone checks the setting.
How to tell if the export limit reset
The financial impact
In summer months, a well-sized system on a G98 connection might export 5–15 kWh per day. At Octopus Flux export rates or SEG rates of 4–15p/kWh, a blocked export limit costs £0.20–£2.25 per day — potentially £50–£300 over a lost summer season before the problem is noticed.
The system appears to be working normally in every other respect. The only sign is that export figures drop to zero in the portal and export payments stop — which many homeowners don't check frequently enough to catch quickly.
Setting the export limit in the GivEnergy portal
The export limit is set remotely via the portal. No site visit or physical access to the inverter is needed.
Steps to set the export limit
Sign in with your account credentials at givenergy.cloud. Go to My Inverter in the left sidebar.
The export limit is found under Advanced Settings — not under System Mode Settings. Look for a field labelled Export Limit, Grid Export Limit, or similar. On some portal versions this may be under Battery Options or a separate Export section.
The field takes a value in watts (W), not kilowatts. Enter 3680 for the standard G98 single-phase limit, or the exact figure from your G99 approval letter. Enter 0 only if zero export is genuinely required. Do not leave the field blank.
After submitting, wait 2–3 minutes for the setting to propagate to the inverter. On a sunny day, check the portal power flow — if solar is generating above household consumption and the battery is full, you should see the grid arrow showing export up to your new limit.
Export tariffs — what the export limit affects
If you're on a Smart Export Guarantee (SEG), Octopus Outgoing, Octopus Flux, or any other export tariff, a blocked export limit directly reduces your income. The export limit is the single most important setting for export revenue.
How the export limit affects tariff earnings
Timed export and the export limit
GivEnergy's Timed Export mode discharges the battery to the grid during a defined window — used on tariffs like Octopus Flux where export rates are highest at peak times. The export limit caps how fast this discharge can export, even in Timed Export mode.
If you use Timed Export on Octopus Flux and the export limit has reset to 0W, the battery will try to discharge but nothing will reach the grid — the timed export window will complete with zero actual export and zero income.
