    So I may be buying a house with P.V. installed....

    Hi Vortigern, I have self-owned PV panels and my parents have rent-a-roof so I can give you some factual answers to most of your questions: My south(ish) facing 3.36kw PV system (with a fair bit of shading in winter, which reduces output) generates around 2,600kwh per year. So, the one you’re...

    Inverter reporting DC voltage too high

    No, can't be a time of year - it has been fine in other years, and if panels are rated such that each string produces ~250v max I can't see why it would now regularly leap up to 600 volts. I did a lot more reading after my post last night and I see that inverter capacitors are the culprit in...

    NEED Legal advice - solar system malfunctioning

    It is a re-branded Powercom/PCM-UPS/SolarKing SLK-4000 - I did replace the relays with high-quality Omron ones. I've actually just posted a long thread with more detail about my new fault (High DC voltage) but its awaiting moderation.

    Inverter reporting DC voltage too high

    My system has had an intermittent problem for the last few months. The inverter has occasionally been reporting PV Voltage Too High, then it would recover after a few minutes. It also didn't do it every day. Now In the last few days it has started to do it more frequently and it appears to give...

    Samil inverter displaying fault

    Hi, did you get the bottom of your problem and replace any caps, or just change the inverter? I have a fault that sounds similar - my DC voltage is too high and the inverter is tripping. I'm going to start a new thread on that rather than hijack yours. I couldn't imagine why the panels would...

    NEED Legal advice - solar system malfunctioning

    Apologies, Dave, I guess by the time I got to the end I was confused. Yes, my message was to the OP, Gedis.

    NEED Legal advice - solar system malfunctioning

    Hi Dave, I'd imagine the issue here is that you have (sensibly) interpreted "lifetime" to mean as long as you choose to have the product, but that is rarely what they mean. I regularly read small-print (very sad!) and I've often seen "lifetime" caveated. They most likely mean the expected...

    Immersion Heater - PV electricity

    Phew... all 50 pages took some reading. I was hoping to build one of these variable immersion controllers but something has just ocurred to me. In the near future I hope to install an Air Source Heat Pump. This will be primarily to supply heating but also Hot Water too. As Heat Pumps are purely...
