    No generation since 3rd August! 24th Aug 17 at 4:58 PM
    Just been entering my import/export readings for the last few weeks (I have been slacking off), and I haven't had anything for the last couple of weeks.

    Week 27/7 - 39kWh
    Week 3/8 - 9kWh
    Week 10/8 - 0kWh
    Week 17/8 - 0kWh
    Week 24/8 - 0kWh



    Generation meter light is solid on.

    Anything I can do before I call the letting agent to have it inspected?

    Our weekly import has spiked to over £10/ week when it is usually less than £4.

    HI
    When you had your panels installed, they should have given you a sheet of info on how to power the system down and up again.
    When powered down leave for a good half hour and the turn on in the right sequence.
    Then check the inverter for any fault codes.
    Can you access via Bluetooth software from inverter company.
    If you can then you maybe see error codes from that.
    regards

    AFAIK, there is an isolator near the consumer unit, and another in the loft by the inverter. There may be one on the DC side too, I can't remember.

    I have no idea what order to flip the switches.

    EDIT: Our inverter is a Samil, a Solar River something or other.

    Procedures in this video, might get lucky, but don't hold your breath.

    Good luck.

    Thanks Mart. I have told the letting agent that the unit has a fault. I might ask if they want me to try a reboot, there only other option is a inverter replacement I guess?

    Can I tell them they won't be getting any Fit as an incentive to get it repaired, or would that be fibbing?

    Hiya, if it ain't generating, then there's no FiT and no export payments as they are paid on generation, so I'd definitely mention it as Sept/Oct are decent months and will lose a fair bit of income.

    Does your lease mention the PV and make great play about reduced leccy bills? If so you might be able to argue for some recompense, but is it worth rocking the boat?

    You'll have to move now, to start playing the PV game again.

    I won't bother going down the route of asking for compensation, I just want them to fix asap. They can be quite slow with things 'they' deem a low priority. Hopefully the loss of fit and export payments will be enough to get them moving faster than usual.

    Well I offered to do the shutdown/reboot and they jumped at the chance. It's quite frustrating because they don't really know anything about the system.

    Anyway, I did the reset and no such luck. The relay failure is still there.

    The letting agent has informed EDF (Fit provider) the land lord (which I'm happy about because he gets things done, and fast), and their electrician.

    Any chance you could give me a run down of what to do next (as if it were my system), so I can keep the letting agent on-track and make sure they are doing the right things?

    Thanks for your help so far.

    I would be inclined to find out who the installer was, then see if they are still in business. I think though all of this would need the person who paid for the system to do the negotiating. At the end of the day, the Inverter was bought from Samil by the installer, who then sold and fitted it for their customer; leaves them 'holding the baby' so to speak...HTH...

    I have been told the installation was done by the original electrician for the house, they did all the wiring from the meter right through to the solar panels.

    They are (so far) ignoring all calls and messages from the letting agent.

    Hopefully something will start to move soon. The letting agent seems to be working pretty hard but the electrician is known to be pretty rubbish once he deems a job complete.

    I'm being told the original installers are being a pain (they are useless with everything tbh), is it possible to just buy an inverter and get another electrician (not the original installers) to fit it? would that satisfy everything regarding fit payments and whatever?

    I'm thinking of suggesting to the letting agent that they go this route.

    Yes to your questions - new inverter has no effect on FiT (apart from ensuring that the landlord earns them!)

    As Samil have gone bust, and it's a relay fault so likely terminal, and as most things these days are not "serviceable", I would suggest you communicate to both Landlord and Agent in same email that they buy a new inverter, which should just be a straight swap out by a qualified sparky.

    If they want to maintain the warranty on the new inverter though, then I'd suggest they source a new installer who installs the new inverter, it has no effect on the FiT for the landlord and means they aren't tied to someone who isnt interested.

    What about setup? A regular sparky may not be able to do this I'm guessing, is that why you think another installer would be the best option?

    No doubt the letting agent will go for a 'cheap option' inverter if possible, but I think I would like an SMA (Sunny Boy) or something. Do you think it would be sensible to put forward this as a suggestion, or is there something better suited?

    Any sparky that is Part P qualified is more than capable of undoing the approx 4 connections, taking the inverter off the wall, put the new mounting plate up (unlikely to be able to use the original fixings for a different brand inverter), hang new inverter, recconect cables, power up and run through setup screen, they are very user friendly these days so even a sparky can understand!!

    Honestly, the sparky is only required to ensure the electrical connections meet current regs - you'll need some help physically as the inverters are around the 25-30kg mark but you can change it yourself as long as a sparky signs the work off!!!

    Cheapest option is buy a used inverter that is still under warranty and take out an extended warranty with the manufacturer - it just so happens my Schuco branded SMA SunnyBoy 3300 is available
    Honestly, it's in the garage sitting on the floor after I retrofitted SolarEdge. Absolutely nothing wrong with it, just weighs a ton so thats why it's never moved!!!

    The setup for my SolarEdge replacement, took less than 4 minutes after power on, so I'd say nothing overly complex!!

    If you search for the data sheet for the SMA Sunny Boy 3300, on page 68/76, 11.2 Techinical data it lists it as 38kg!!

    The innovative design of the Sunny Boy 1.5/2.5 is not only easy to install, but also allows for quick DC and AC connections. For example, because it weighs just 9 kg, it can be suspended from just two screws, with no additional wall mounting bracket.
