    UK grid-tied 3.68kW inverter connected to ring mains?

    If I was going 'to do what I like' I wouldn't waste my time here would I. I would just get on with it because job can be done safely and in a cost effective way with much less effort than this. This is about getting it done in an approved way and signed off with Part P / BC if required. If you...

    UK Hybrid ESS / paper work / approval

    Honestly that would work for me but guess I'm having trouble finding anyone happy to do it (or even a basic CU connection) except by an official installer. It sounds like the key is already knowing someone who does work for you directly/indirectly. Guess if you just contacted at random it's...

    UK grid-tied 3.68kW inverter connected to ring mains?

    Someone on the electrics... forum suggested that they might connect a small inverter to the ring mains or that there was already some product that does this. Naturally they were met with hostility as that seems the norm for that forum. Specifically there was some bitching about this overloading...

    UK Hybrid ESS / paper work / approval

    Seems fair enough guess I'd definitely like to proceed in whatever way is going to be the most cost effective way that I am allowed to use. After a circa 40% increase in the night rate (and lowering of the day rate which makes the potential savings much lower) from one energy provider as well as...

    UK Hybrid ESS / paper work / approval

    @kommando thanks for confirm that, explains why their site is not updated. Got the distinct impression there may be some kickbacks involved in this. You pay for your saving in advance and they just give you back your own money.

    UK Hybrid ESS / paper work / approval

    @SeaGal Thanks for taking the time to reply sort of as expected, useful info about the installer details and octopus (although I refused their service for other reasons and I believe their site still says the opposite) and yes correct about the forum, seen similar on screw*** but less surprised...

    UK CU connection for inverter

    In some respects it might be nice to start a thread with typical costs for certain jobs you are probably going to be forced to get done by a 'professional' I think that inflation may have been used as an excuse to double the typical price of some jobs. It was at least my experience that even...

    UK CU connection for inverter

    @kommando Thanks for your reply. I think your comment that you felt you needed an angle to come at him with to make him play nice tends to speak volumes. It sounds like it must have been expensive to change the CU. Out of interest when your CU was changed did he have to go to every socket /...

    UK CU connection for inverter

    I feel I have already run into a headache with regards connecting the Inverter to a CU. There seem to be a number of problems. Sparky may refuse to connect equipment from different manufacturers. Existing CU manufacturer is defunct and it's an old edition so not very realistic picking up new...

    UK consumer unit branding uniformity.

    Here is the supposed advisory.. https://electrical.theiet.org/wiring-matters/years/2021/87-september-2021/myth-busters-7-out-with-the-old-in-with-the-new/ Basically it is the IET passing off responsibility for any problems to the installer. This is probably just to exempt both the manufacturer...

    UK inverter breaker sizes and tails

    I can tell you Sunsynk only recommend 8mm2 cable with a 50A breaker for both grid / load ports. This is for the 8.8kW ECCO inverter. 10mm2 is the next cable size up which I think is suitable for loads up to 64A (clipped direct - assumed typical mains cable). The neutral fly lead on a 50A RCBO is...

    UK Hybrid ESS / paper work / approval

    I've been so focused on what to buy that I hadn't looked too much at the paperwork etc. I've already ordered part of it and now full of regrets fully expecting that by the time I have negotiated sign off of my installation I'm going to have spent so much money it will never be worth it...
