    Large pv display

    Good stuff, thanks

    Large pv display

    Hi *waves*

    Voc and Vmpp in practice

    Don't forget that the datasheet values are at STC and that the voltage has a negative temperature coefficient....other than that, what Bruce said!

    In Court

    I know, odd isn't it....maybe there are other reasons but the couple of conversations I've had, with the likes of BRE etc, have tended to refer to RCMUs and DC ground faults etc. I think Martin Cotterell's blog may have touched on this recently too

    In Court

    They're coming from the angle that the inverter's RCMUs need to have the frame earthed (with TL inverter's) Bruce......the fallout will be "interesting"

    Enphase set up

    Several micro brands allow you use the wireless gateway just to set up the system and then take it away with you

    PVSOL7 experience?

    Anyone out there who is proficient with PVSOL7 and would be interested in some sub-contract design work? I have a client who needs some help..... Andy

    Which way electricity will flow ?

    Maybe Pablo knows something about grid-tied synchronous generation and active power flow that nobody else does....I'm waiting to be enlightened....

    Three phase Immersun equivalent - does one exist?

    Elios4You PRO Bruce - aggregates generation and import/export measurements across all 3 phases. Calculates local consumption Has the same analogue output for proportional immersion control as the 1phase Elios4You. So, you can dump excess proportionally via the separate Power Reducer to a 1ph...

    Solaredge zero output

    Ah, the AC side, of course, apologies! Plenty of DEHN options there too though, give me a shout if you want details. (The cube works with a handy X-type or Y-type pre-assembled/moulded splitter cable, so you can retrofit the units just by unplugging existing string input and connecting the...

    Solaredge zero output

    Type2 DC SPDs with a decent operating voltage would probably be a better idea Gordon, something like these are an easy retrofit

    Adding extra PV using same inverter

    Yes, 55kWp of PV modules will be >50kWp FiT band, regardless of the peak output of the inverters. No, I don't think all sites will be audited. What do you mean by "your formula" though, out of interest?

    Adding extra PV using same inverter

    Pablo - you wouldn't be the first to point out the inconsistencies in the understandings of TIC/DNC definitions and Ofgem's stances on this, and how it relates to the UK's FiT framework, and how that framework is designed etc. As has been advised already, the FiT bandings are based on kWp...

    Tensile steel mounting solutions

    Hi all, Anyone ever had a look at this type of mounting system before? I've been talking to a European manufacturer who has some very interesting tensile steel solutions that can not only be used for "standard" requirements, but also offer some clever solutions for array locations normally...

    devices to restrict export

    Hi Gavin, fair point but it's still a G59 installation though, isn't it? The inverter is simply being limited, it will still respond to/protect the grid based on its G59 settings, the export limiting solution shouldn't interfere with that. Or was the engineer you spoke to suggesting that the...

    devices to restrict export

    Various DNOs are now catching up with the available solutions in the marketplace, and there are efforts by the likes of the BRE to put together a standardised document/guide for designing/implementing export management and commissioning (not easy!). Worcester is correct in that Germany have...

    Bad Installation

    I also recall some early issues with the small Samil units but can't quite put my finger on what it was. As a potential alternative, we have a 1kW unit that has a 60vdc min MPPT rating, suitable for 400-1100Wp depending on panel type.

    MOnitoring domestic

    Dan - if the generation phase(s) and mains incoming phase wire is within a few metres of each other then the Elios4You will do exactly what you are looking for.
