⭐⭐⭐⭐⭐ Absolutely Outstanding Service! My GivEnergy system had completely gone down, and unfortunately I was getting absolutely no support from either the original fitter or the supplier. I was left completely stuck with a system that wasn’t working. I contacted Solar Tech Support and they were absolutely brilliant from start to finish. They quickly got to the bottom of the problem, knew exactly what they were doing, and managed to get my entire system back up and running. Hands down, these guys are absolute experts in their field. The level of knowledge, professionalism and customer service was exceptional, especially when I’d already been left without any support elsewhere. If you have a GivEnergy system and you’re struggling with an issue, don’t hesitate to contact Solar Tech Support. I honestly can’t recommend them highly enough. 5 stars all day long! 🌟🌟🌟🌟🌟
Solar system not producing electricity
- Check the basics before calling an engineer
- Fault code guides the diagnosis
- Monitoring offline ≠ not generating
A remote diagnostic session reviews the event log, portal data, and system configuration to identify the cause and tell you whether it needs an engineer on site or can be fixed remotely.

Even better, he explained why the storage batteries don't work in a power cut - not correctly wired up - expensive to fix, but a simple turn of the master switch will give emergency power. He is the third technician to look at this issue and the only one to resolve it. Friendly and appoachable, comes when he says he will and reasonable charges. What's not to like!
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!
Ronald at Solar Tech Support was very quick and knowledgeable in helping me restart my GivEnergy solar electric battery. I would highly recommend his services.
Excellent service from Solar Tech Support. Extremely quick to respond, easy to deal with and clearly very talented engineers. They were persistent throughout a complex GivEnergy battery issue and resolved everything completely. Highly knowledgeable, professional and reassuring support from start to finish. Highly recommended.
This is the second time I have used Solar tech first time a faulty Givenergy inverter, tried all sorts to get it going my last call was to Solar tech and yes they got me back up and running, today system went down again due to a firmeware update and Ron talked me through everything all whilst he was on someone’s roof sorting their system out. I would recommend this chap to every body that has problems with their system no matter what make..
First: check the inverter display directly. If the monitoring portal shows zero but the inverter display shows a live generation figure in watts, your system is generating — you have a monitoring connectivity issue, not a generation fault. See monitoring offline.
Why a system stops producing
Starting with the most common and easiest to fix.
AC or DC isolator switched off — after a maintenance visit, a power cut, or accidentally. Easiest fix: check all accessible switches and turn back on.
The solar MCB or RCD in the consumer unit has tripped. Reset it once — if it trips again immediately there is an underlying fault.
The inverter has tripped on a fault and is showing a red light or fault code. Find the code, understand what it means, then decide whether a single reset is appropriate. See inverter red light.
If the grid supply is absent or outside limits, the inverter disconnects and stops generating (G98/G99 compliance). Generation resumes automatically when the grid returns. Check whether your house has any power at all.
A blown DC fuse, open-circuit string, or failed panel is preventing solar energy from reaching the inverter. The inverter may show no fault — it simply has no DC input to convert.
Less common. The inverter itself has failed — from age, power surge, or component failure. Usually shows a persistent fault code that doesn't clear with reset. Requires engineer diagnosis.
How to diagnose zero generation
Work through these in order on a day with at least some sunlight.
Go to the inverter physically and check its display. If there is a fault code visible, that is your starting point. If there is no display at all — completely dark — the inverter has no AC power. If it looks normal and shows output wattage, but the portal shows zero, you have a monitoring issue rather than a generation fault.
Locate and visually check: the AC solar isolator (usually a red rotary switch near the consumer unit), the DC solar isolator (on or near the inverter, often labelled DC ISOLATOR or PV ISOLATOR), and any battery isolator. All should be in the ON position. Switches can be knocked off accidentally during maintenance or by curious visitors.
Open the consumer unit and look for any MCB or RCD that has tripped (in the mid or down position). Solar circuits are usually labelled. Reset any tripped breaker — if it trips again immediately, do not force it back on. Call an electrician.
Open your monitoring portal and look at the event log. Find when generation last showed any output and what events occurred around that time. Fault codes, firmware update events, and connectivity losses are all logged and will point you towards the cause.
If the isolators are all on, there are no tripped breakers, the inverter display looks normal, but generation is still zero, the issue is likely a DC-side problem — no solar energy reaching the inverter from the panels. This could be a blown DC string fuse, open-circuit string cable, or panel-level fault. This requires engineer investigation to diagnose safely.
Brand-specific zero-generation checks
Some brands have system modes or monitoring quirks that make a system appear to not be producing when generation is actually occurring. Check the note for your brand first.
GivEnergy hybrid inverters have a Backup-Only mode that prevents grid export and can make the system appear to not produce to the grid — but solar is still generating and charging the battery. Check the System Mode setting in the GivEnergy portal before concluding zero generation. See the GivEnergy hub for portal navigation.
Growatt hybrid inverters have a "Battery First" power priority mode that suppresses solar export in the monitoring app even when the PV is generating. Also, Growatt ShineWiFi dongles drop cloud connection regularly — always verify the inverter display shows live generation data before concluding zero output.
Sunsynk inverters can enter a latched fault state after a sustained grid event, displaying zero export figures even after supply is restored. A controlled restart — AC isolation off, DC isolation off, wait 2 minutes, restore in reverse order — typically clears this state. If the fault recurs, log the event code from the Settings > Fault Log menu.
Frequently asked questions
Worked through the checks and still not generating?
If the basics are all correct but generation is still zero, a remote diagnostic session can review the full event log and system data to pinpoint the cause — and tell you whether it needs an engineer visit.
