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.
Book your free remote diagnosticSolar system repairBrilliant 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.
Ron was brilliant. He really tried to help. He spent hours trying to fix our GivEnergy AIO and ultimately it became apparent that it needed parts to fix the BMS management system. As there appears to be no replacement parts available on the market, he gave excellent advice on what options are now available to move forward. He is incredibly helpful and knowledgeable.
Called back within a day and gave good advice.
Ron was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
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.
A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.

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.
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.
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.
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.
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.
