> They shouldn't be that close to the absolute maximum voltage ratings on the components.
This appears to be a situation where the engineering team determined the absolute maximum input voltage and the marketing/product people put that number straight into the documentation.
Standard practice with electronic parts is to determine the absolute maximum rating, then to specify a recommended maximum that allows for some safety margin and variation.
Instead, this company determined the absolute maximum and then just shipped it.
One way or another, many of us are in agreement the company screwed up and it’s on them to fix it - whether that’s their marketing, their manual, their lack of over voltage protection, whatever it is it’s their fault.
Yet so many people in this thread are so keen to blame the customer, it’s pure ego from them. “I’m too smart for that to happen, so it’s all their fault!” they sneer. Classic bad faith forum behaviour…
That's humanity in general. But yea- general guide says "add up your open circuit voltage and don't exceed that." If something fails because of the panel manages to get more than 1000W of solar flux, and is cold... it's the mfgr's problem.
I need to actually look up why the extra flux increases voltage. Maybe it really doesn't but just moves the MPP to a higher voltage by having more current.
