    NHS issues safety alert on socket covers requiring removal from NHS premises!

    Non-electrician here, just someone who enjoys reading this forum, but also a parent. My wife bought and fitted these socket covers some time ago for when our now 2 1/2 year old was crawling. I was talking to her only a few days ago about removing them after reading this thread. Anyway, I...

    Battery Battery Storage & Metered Export

    My understanding is that batteries wired on the DC side e.g. between panels and inverter would not be a problem and meet the core principle in 4.29 that all export is from the FIT installation. The diagrams in the Ofgem document have the batteries on the AC side of the inverter and so...

    Domestic three phase with single phase PV - net metering

    Thanks for the link. It's worth me checking it's working as it should (or get them to), since it leaves the possibility of B even though it should be A.

    Domestic three phase with single phase PV - net metering

    Another family member had a number of eco features added to the home when built a few years ago. This included a ground source heat pump, hence the three-phase, and solar PV. I had a look at the setup recently and observed the solar PV is single phase. Furthermore, it is on a phase with one...

    Larger 6kWp+ domestic install before the FIT cut

    Following up my original post, I did get a system installed in December on the old FITs, but not in excess of 6kWp though! It comprises 20x 250w panels to give 5kWp fed into a SolarEdge SE4000-16A inverter, so done under G83/2. This is within the warranty limits of the SE4000-16A. It was a...

    Larger 6kWp+ domestic install before the FIT cut

    BruceB - I'm guessing you're the same person responding on the other forum I where posted similar question (and I'm getting really helpful responses from both) The oversizing note states that the maximum oversizing ratio allowed is 135%. However, it also states the AC output for this...

    Larger 6kWp+ domestic install before the FIT cut

    Another oddity is the latest SolarEdge datasheet for the SE4000-16A (dated Sep2014) states the max DC input is 5000w, a slightly older one (Feb 13) has 4400w while a datasheet for the SE4000-GBR (dated Jul 11) has 4100w. the max has been getting bumped up over the years.

    Larger 6kWp+ domestic install before the FIT cut

    Thanks for the replies so far. The unusual thing about the SE4000-16A is that in the G83/2 type test certificate (and data sheet), it is shown as AC rated at 4000w, so not 3.68kW, potentially giving a gap. However, the 'G83 certificate' and device itself will show 3.68KW as the rating though...

    Larger 6kWp+ domestic install before the FIT cut

    I'm not an electrician, just a householder (though do work in an area given a kick in the family jewels by government decision last year). I am technically minded so want to understand that proposed systems are worth the spend. I have a decent south facing roof space that can take around 25-27...
