Hello Mr Ball i know the system is now working after we visited today but i had to laugh when i saw this post just now.
My company installed this system last week.
After talking to Mr Ball on Monday i also made the same assumption as you guys and arranged a re visit.
I found that one of our contracting teams had decided to ignore:
1. PV sol calculation sheet.
2. Schematics showing 2 strings.
3. The 6 pole dc isolator in their kit.
4. Common sense.
They had not only wired whole array on one string but had lifted a hip roof tile then wired cable under hip tile then cemented back in to reach panels on other side of roof!!
They also installed 2 ac isolators 12 inches apart.
I should of taken photos but was so embarrasssed i sorted it immediately into 2 strings.
Also a whole catalogue of small errors that are too tedious to reiterate that i also rectified when i was there.
Shh dont tell him.....lol
Luckily Mr Ball came here and got as always friendly and helpful answers.
Cant wait to get rid of these rough neck contractors on our company (from an original 4 teams before tariff cut to 22 teams)
I may post some photos of the horror stories once its all died down.
Here are some of my electrical instals to show i can also walk the walk.
