LOOK can we ALL live the REAL WORLD how on earth can joe public KNOW if their install does not confrom to all relavant regulations untill something goes wrong, by then its to late. Below is a list of qulifications my installer SAYS he has MCS Accredited Renewable Energy Awareness

TBH NAPIT would agree with Ivor, , Common sense NAPIT don't have any

Mr Manator ,whilst I agree with 95% of your thread, how can I get NAPIT involved when,every time I complain they stonewall me,I pressum you have read their emails, Also, how can I,your quote, do not use any of this installation until you are satisfied has the duty holder that the installation...

Yes its high up about 10 foot ---------- Post Auto-Merged at 20:14 ---------- Previous post was made at 20:13 ---------- Yes its mounted on wood..........bit worried now

Has this worked

Now about this one way street,could you please tell me what volt drop I will get on SWA 25mm2 3 core on a run of 54meters ,253v at the CU with .4ohms grid impedance, generating 17.4amps ---------- Post Auto-Merged at 18:23 ---------- Previous post was made at 18:19 ---------- Strange, they...

OK,OK,here are som photos one of the house CU,one of the inverter,one of the roof trusses,one of the barn with the panels on ---------- Post Auto-Merged at 18:04 ---------- Previous post was made at 17:23 ---------- He's paying'but I will offer a contrabution (we all have to eat) He has said...

Point 1.Yes agreed 2.No I don't 3.He says, Uacmax =253v means the graph is for G59, I have no idea 4. I agree with you Dont leave me now I need you:worship

Thankyou ---------- Post Auto-Merged at 20:12 ---------- Previous post was made at 19:59 ---------- I had the installer round today , I showed him page 3 of the SMAs Grid Connection Technical Information guide I highlighted the graph which showed .4 grid impeedence at 250v would only allow me...

OK, Here are some voltage readings 532w 2.1a 243v 276w 1.1a 240v 267w 1.1a 237v 251w 1.0a 240v 187w .7a 238v 169w .6a 240v 161w .6a 241v hope this helps

LOOK this solution is not going to happen ,so why discuss it ---------- Post Auto-Merged at 23:12 ---------- Previous post was made at 23:11 ---------- Thanks for that

And the grid impedance measured at the inverter is .97ohms

It is 130m of twined 6mm then 20m of 4mm twined
