Hi there, great short video! I haven't seen that fixing system for renusol before, I thought you had to run full length rails. Yours is much easier. I have posted a few videos of solar installs that i have helped with and I am running an ABB like yours and a SAJ and Solis, to spread the load thin and benefit from different aspects. If only I had a shed like yours!

@@BuyitFixit That's what it's all about. Loads of people want to see solar stuff at the moment just to get a feel as to whether they could have ago or if they need to get help. Not many of us out there chopping the tops off relays. I saw what you did on the samsung washer too. I didn't think those rubber potted boards could be rescued. You've got patience. Most of my videos are about washers, I'm running one of those inverter samsungs now, found with a broken door. Lovely and quiet! Keep fixing.

Since these are transformerless inverters with no galvanic isolation, the panels / panel mounts should have earth wiring. In practice they will be earthed through the building - but likely not up to code.

Just out of curiosity; The other faulty inverter you bought, did it suffer from the same problems as the one you showed us repairing of (burned relay connections and shorted diodes in SMPS)?

Just the relays. The rest of it was fine 👍

I like that you mentioned the product name of the mounting kit. Concerning the whole install, the mounting kit was around 33% of the price of the panels, wasn't it? It looks like they cost around 100€ per panel and the biggest panels I found were less than 300€ in price.

The panels were around £131 each so £2100 for 16 of them. The two inverters cost £130 including parts to repair them, and the mounting system around £350 and isolators etc another £150. Hope that helps!

@@BuyitFixit Did you consider other mounting systems? Or did you have resons not to choose another system? I like the one you choose. However, it seems to be the not one to buy spontaneously (forgot to add the "not". I didn't find it in Germany. It is always "price on request", "unavailable" or something like that).

@@BuyitFixit I thought it was only me or a local problem to Germany. I wonder why that's the case. Maybe, because it is hard to make profit with those things, if they are not sold in bulk or from China. The same is true for some inverters. Everyone talks about MPP Solar Hybrid inverters on youtube, but I never found them in Germany, although some youtubers like Marco Reps apparently got them. And the ones our Electrician recommended like Fronius Solar, are not available this year. For big solar systems they are not even that expensive. But just not available.

You probably have similar problems with detaching roofs due to storms while having similar safety standards we have. In the US they seem to be just fine with rebuilding their houses every now and then and in Australia, they just don't have the constant shit weather. And your environment in the UK doesn't try to kill you every day. I've been on a farm in Australia for a week, and they seem to have a real fear of spiders there, and probably for a reason. Furthermore, I like the trees and nature in many parts of England.

How do you isolate the PV panels while wiring them up? Or did you do that bit at night? 😂

I wired up the DC isolator first, to two mc4 connectors. Then connected all the panels together, and plugged them into the two wires going to the isolator.

Did you use self-tappers to fix it on the roof? I have never used self-tapping screws into metal yet. It feels like it will work itself loose at some point. How many kgs of force would you expect them to withstand per screw? And how likely is it that the connection will start to leak at some point? Does someone have long-term experience with how that works out after 10-20 years? Our electrician recommended us to install something similar, but he told us about a system where you can slot the panels into one side and leave the other side hanging down to avoid internal forces. As we live in a windy place, I wonder if the storm can lift the cells out of that system. Technically I would prefer something exactly like your solution. He claimed that lowers the risk of the construction starting to work loose and to start to leak.

We live in a VERY windy area also! The screws are stainless self drilling ones that come with the renusol fixings. The screws are quite thick and are similar to what holds the sides onto the metal beams of the shed. The whole system is called renusol metasole+. The rails are the 400mm ones. 4 screws hold each rail and 4 rails per panel, although 2 panels can share a rail if in the middle. If you search metasole+ I'm sure theres a data sheet of the kg and wind resistance etc.

@@BuyitFixit I think I found the manual for it. So it is corrugated roofing sheet, then the rails, then the seal, and the screw goes through the whole thing. There seems to be no seal between the corrugated roofing sheet. Isn't there a risk of a leak there or corrosion happening? Apart from that I only find much more expensive offers from that company :/.

@@BuyitFixit Thank you, your description helps a lot. I didn't see the rubber strips when skipping through the manual. The price might be due to the inflation, which we have here. I only find offers of around 250€ to mount three panels, and those offers are not even available right now. The rest is "price on request". At least I know that they exist and how expensive they have been at one point. I should research the system our electrician talked about and compare those. I always get the impression that in Germany, people use fixings like the "Renusol 920008 M10x200 Hanger Bolt Wood" (maybe because of wooden sub construction?). When I search for that item, google leads me to an English page. Maybe there is less panic buying in the UK right now.

Good question, and unfortunately I have no idea. I know the shed next to it is 15 degrees and the one I put the panels on is either similar or less, which probably isn't the optimal angle for maximum output, but I still get pretty good results.
