Update:
Ironically the customer phoned me yesterday and i was 20 minutes away (i wasn't planning a visit) so i called in for an hour to take a look.
Firstly the system: The standard of work isnt too bad, ive seen worse, its not how i would have done things & its a little scruffy, but it is labeled up and they used 6mm on a 1.5kwp job, new sub board so it could be worse.
The mounting system is schuco using hanger bolts through slate with what looks like so sort of felt under the bolts in case a slate cracks, neat roof work to be honest, but i dont like hanger bolts through slate - but hey ho its my preference.
Now the ugly: The inverter an "omnik" 1500-TL had a fault on it, "Vac" failure - its cutting out at 250v grid voltage - the incoming supply is high at 248v, the inverter boots up and as soon as it reaches 250v it cuts out - can anyone back me up with my thoughts - i think its a European inverter and not destined for the UK, otherwise it range would be up to 259v? is this correct? it says G83 on the inverter label, but nowhere can i see "GB" in the serial number for example or any proof its set to UK - don't forget these are cheap Chinese with not much option to set them up. I will speak to omnik and give them the serial number to identify which country its set to.
Now for the really good part: I was shown the contract also - picture this in your head - elerly couple in there 70's, shiny suit comes in, gives them waffle about this and that, ohh how its going to power the world for you - 6 Canadian solar 250w poly panels, omnik inverter - how much £££ do you think? yes i nearly fell of my stool at £12000 TWELVE THOUSAND POUNDS - Jesus wep and the sad thing he got the cheque book out and paid on the day!!! luckily he came to he senses and complained, they came back and reduced it by £6000 SIX FREAKIN THOUSAND! whaaaattttt honestly are these folk for real? (no pun)
Poor couple, they also told they need LED and optimiser. joke.
I now feel uncomfortable, because the inverter has a fault, ive explained to them, but im going to ask them to bring along a son or daughter for my next visit because i don't want them to feel like im trying it on also. There really upset and confused by it all - very sad case if im honest.
This system has generated 31 units since beginning of Jan, my system i put in last week (granted it is larger) did 33 units last week - let alone a over a month. Robbing C U next tuesdays.
