OZ;
My stance remains for safety.
Your knowledge of electronics is light years ahead of mine.
I don't like being part of the wolf pack either, but,,, the units you have been able to inspect, if you have pics , I'd certainly like to compare those versus the ones available to us.
Of the different sizes I've had the luck of seeing inspections and installs for , only one was done the correct way.
AND you are very correct, it cannot be the fault of the unit if the installers do not do it right the first time, no matter if it's a cheap unit or a high dollar one. BUT the insurers are the quickest ones to jump ship !!
I have the good fortunate to work with FIU, they are the ones that go to a fire and determine was caused the fire and then report them to the insurance agencies.
Once I get the clearances I'll post the building that this occurred in and what it looks like now, but American lawyers being the way they are
, I could be of retirement age before then!!
The fires aren't caused by the grid going down, they are caused by these units failing inside or low quality QA inspections.
This might look familar
.
It is very unfortunate , cause the poor guys were sure they had done everything correctly.
OF all things, the one place the I was quietly fighting with MWS has actually put out a nice video of how to connect it correctly.
https://www.youtube.com/watch?v=S93wbGlzsJgI'm not one to give out free advertisement, however, for those located here in the USA and are thinking of using these units,,, PLEASE watch the posted video.
AND pay attention to the part about NOT over driving the unit.
I do not grid tie, my poky little 100w system is way to small for that.
The unit that was installed the correct way,, is for solar only and even I pulled the AC plug and measured it just like the guy in the video, I lost a 3-drink bet on that one.
Cheers
