    PV+ - anybody heard of this?

    Guys, don't get sidetracked into the same old VO conversations - I think we all know our opinions on those (at least in a domestic environment anyway), this PV+ unit is pitched as something different....I for one would like to know exactly how this is supposed to differ from VO and how it's...

    PV+ - anybody heard of this?

    Maybe we'll get some input from Matt Hunt on here, I know he's been on before....some explanation/answers would be interesting

    PV+ - anybody heard of this?

    It's a Matt:e product and I'm sure it has its place, but if you're not suffering from regular over voltage trips then I fail to grasp the point....seems like a solution to a problem that shouldn't exist...I've questioned the ER grid-connection compliance/impact of this technology before, but as...

    PV+ - anybody heard of this?

    Is your inverter regularly tripping out due to over voltage?

    Off Peak Charging through Hybrid Inverters

    I think I've seen mention of a 10% loss factor being used, in some of the marketing info being put out on LinkedIn etc.

    Replacement panels for a defunct manufacturer

    (Here ration = generation) damn autocorrect!

    Replacement panels for a defunct manufacturer

    But then, they are hardly going to completely revamp the "FiT" banding structure, hence why there are two questions to answer "no" to in their wording above....which kinda makes sense then - don't affect the banding, and don't affect the here ration capacity, and you're ok?

    Replacement panels for a defunct manufacturer

    Gavin - perhaps Ofgem are wording it as generation capacity because they are finally seeing the sense of ignoring the amount of watts-peak installed on the DC side?.....or am I giving them too much credit?

    Replacement panels for a defunct manufacturer

    Indeed Ted, this ongoing saga with TIC/DNC definitions and restrictions is continuing to be a pain in the proverbial. I'm seeing similar inconsistencies and poor consideration/wording with recent export limitation policy from various DNOs too, although it has to be said that they are all pretty...

    Export payments no longer apply for extensions as well as no FIT payments

    Thanks Gavin, does this apply to system above and below the 30kWp threshold for deemed 50% export?

    Domestic three phase with single phase PV - net metering

    Most likely to be A. Do you know what make/model of 3ph meter it is, or full product code?

    I had a 25% discount code when I bought mine, SEUK2015, not sure if still valid though

    It's a very broad overview isn't it.... Are you saying you didn't buy the IET PV CoP yet?!...tut tut ;)

    Exactly Davesparks....although, CBR600 didn't explicitly state that it was a TypeAC RCD fitted.....benefit of the doubt and all that...

    Pv on rcd

    First thing, I'll reiterate what several others have already said - for transformerless inverters, always try to "design-out" or mitigate the requirement for an RCD in the first place. All transformerless inverters will have a degree of inherent leakage current. I think that G83/2 requires...

    Fascinating...

    Two identical systems, one 20% down...

    Assuming you tested the strings whilst open-circuit, did you monitor the "on-load" voltage and current values reported by the inverters too? Just curious as sometimes panels can behave differently when actually outputting current. Shading is most likely to be the culprit though tbh. Unless...

    Battery Battery Storage Gets A £1m Boost

    Completely agree, I believe discussions with DNOs are ongoing, but it certainly seems that some of them are considering some systems as adding generation capacity, for some strange reason. Maybe it will become clearer/more sensible soon
