How the HELL do you Replace a Failed IQ8 Microinverter?
I Installed a 10 module/IQ8 minroinverter (m/i) tracking PV array 6 months ago in the Hebrides, Scotland, UK. Unfortunately one of the inverters failed 5 months later. I bought Enphase kit this time because the last time I installed it (15 years ago!) it was very simple to do and worked very well. I requested a replacement m/i from Enphase and that all went very smoothly, the new one arrived in about 2 weeks. However, included with the new m/i were precisely *zero* instructions as to what to do next!! Searching the web generates a vast array of conflicting, out of date and plain irrelevant info from Enphase. After a *great deal* of time messing around with the app on my iPhone using the Enphase Toolkit app found the following (for the benefit of someone else in the same boat) goto the system in question, scroll right to the bottom > 'Service' section, click on 'Replacement and RMA Service', 'Replace Devices', 'IQ M/i...' , 'Install Replacement'... and enter the old and new m/i serial numbers (you did remember to make a note of it before you buried it behind the PV module up on the roof, didn't you?(!)), then you have to email Enphase using the email address on the enclosed form and a couple of days later (in my case) the new m/i started working ). To say I am frustrated is the understatement of the bloody year! I do *not* think I will be bothering Enphase the *next* time I install a system unless they pull their flaming finger out and sort out this God-awful mess!
