does it has a zero export built in systeme ?

Any updates on the cause of an internal Riso fault like this? I've just experienced the most amazing - and unfortunate - coincidence with a couple of these inverters. My Aurora One developed the common E031 fault, so I replaced all 4 relays. Refitted the inverter, and it immediately returned a Riso of 0.00 ohms, regardless of which of the two PV strings were connected - very strange. As a complete ZERO-ohm Riso on BOTH strings didn't make much sense, I assumed that I'd messed up my repair and caused this new issue myself, so I bought a professionally-refurbished Aur-One to replace it with. Fitted the new one, and it worked - for around 5-10 minutes! I'm sure I heard a wee 'zzzp' from inside it, my RCD was tripped, and when I reset the RCD, this new inverter ALSO gave a Riso of absolute zero! What the heck?! Ok, going a bit crazy, I checked the cabling of the panels, and replaced the original connectors with MC4s, even tho' they all looked ok, and the cables had no visible damage at all. Unsurprisingly, this made no difference - still a complete ZERO Riso! By now, I had to suspect the ridiculous - TWO Aur-Ones had developed an internal Riso fault, at pretty much the same time! I essentially proved this when I luckily found a new-old-stock Aur-One which I got for a good price, and fitted this. It worked perfectly - and still is, months later. That means that TWO Aur-Ones developed the SAME zero-Riso fault within minutes of each other - no wonder it drove me crazy. I opened my original inverter for a physical look of the boards, but could see nothing amiss. The refurbished one was returned under warranty, and they provided a full refund. I did ask if they'd let me know what the cause was, but they sadly haven't replied, so this remains a mystery. I'd love to know what the internal cause of this Riso fault is 🙂

My alarm is on .what is wrong?

Ohh good

If i had one of those, I would love just to save more money, And by having big amount of bills on my own, I can't survive in life. could you please give me some? 😅😅

Hola

Thanks for the video and info. My system has failed at some point over the last month or so, within a few weeks of a smart meter being installed - coincidence? - but I can't get close enough to the unit to do anything myself (mobility and access issues). Installer went bust a couple of years ago (then reopened under new company) so looks like I've got some fun & games with the insurer/warranty, and I've got to find an electrician to do the work. Sheesh!

same problem as you. Did the new inverter cure it please?

Those panel leads look like Amphonal H4 connections. They melt and fail all the time. MC4 is the way to go. Also don't plug Amphonal to MC4. Only MC4 to MC4

Did you cable tie the box's and secure them to a joist?

I replaced a customer's Power One PVI-3.8 with a "Missing Grid" error about a month ago. The new inverter worked for the first few weeks, but after the first rain its been having a ground fault with RISO measuring 0.1 MOhm. Anyways, headed back today to check the panels and connectors like you did in this video. Cheers!

Don't forget to carry out an insulation resistance test with the circuit earth connected in the main earth bar and put one your test leads on the main earth bar ..

Always problem riso 😑

Well done on finding that fault!

6:17 that is a really tough cable.

Great video, so I assume you cut out the piece with the nail in it and then the white flex joined the two wago boxes together?
