Re: New PV Installation only half working and Installer giving the silent treatment..

Any shading on the panels? This could kill the second string as well. Otherwise hopefully its just a faulty connection or as others said reverse polarity.
 
Re: New PV Installation only half working and Installer giving the silent treatment..

you would still have something if it's shaded
A complete absence of power is a dodgy connection or reversed polarity

Yeah good point Moggy

Sorry - completely off-topic, but, 'love the new avatar, Biggs - what a loss... :sad:
 
Re: New PV Installation only half working and Installer giving the silent treatment..

Thanks Scoob :-)

Yeah, heard about it on my hols - absolutely gutted.
 
Re: New PV Installation only half working and Installer giving the silent treatment..

Sorry for the delay in getting back to you guys..... After a couple of letters to contractor stating my position I finally got hold of one of the main guys and a sparky came to the house. He found a connection not made up and blamed the roofer! This is coming from the guy who apparently commisioned the system and said that all was working fine!! I'm now waiting for contractor to come back and bolt my optimisers to rails with two bolts rather than just one as per the manual. More battling in the new year methinks... Hopefully they will also tidy up the cabling to stop it flapping around all over the roof when they are here? Do installers normally cable tie cables to rails?
 
Re: New PV Installation only half working and Installer giving the silent treatment..

Yes they should cable tie the cables to the rails.
Your system should be up on your roof, working for 25 years, if the cables are flapping about in the breeze there is a fair chance they will rub through causing them to short out. I think you have guessed that yourself.

Hope this helps and good luck.
 
Re: New PV Installation only half working and Installer giving the silent treatment..

securing cables is a requirement of the regs
 
Re: New PV Installation only half working and Installer giving the silent treatment..

Gents, sorry for bing away for so lond and not reporting back sooner. One problem remedied you seem to quickly move on to the next....

Finally I managed to get the installer to send round a sparky and a roofer. They quickly found a loose connection and once connected the panels paired up nicely. During their visit I asked them to tidy up all cabling and ensure that all cables are up off the roof and no lengths are flapping around. The guys did this whilst they removed each panel one by one to secure each optimiser with two bolts instead of just the one. The guys also found at least two tiles under the panels that were smashed. Obviously the initial installers thought that I'd never know, that is until the water started to pour in!! I must say that the guys that came round were 1st class and couldn't do enough to help. Anyway, that is it, the system is working well and I can monitor via teh Solaredge online portal as I have connected my inverter to my router. 11.2kwh seems to have been the best day I've had since Nov11. Here is hoping for many more sunny days! Thanks again guys for all your comments, hopefully I can be of help to someone some day? All the best. Craig

Re: New PV Installation only half working and Installer giving the silent treatment..

it's always good to see an installer ( whether it be solar or not ) come back and fix any issues to the customer's satisfaction. OK, we all make mistakes from time to time, but fixing issues like thi sis what distinguishes genuine sparks/pv installers/ whatever, from the cowboys.
