Some can be repaired, Midnite Classics for example. Midnite hawkes bay and barcelona 600V. Probably also the rs450 series in metal cases.
But hard to beat a 150/100 or 250/100 with 5 year warranty, make sure you buy it from a dealer that has a great reputation for support like current connected.
The dealer I got all my stuff through is the biggest in the country (Australia) I believe. Many other dealers send their warranty stuff to them. But having now discovered, in order to open the case you have to half destroy the unit, I can see why they say, "duh if U have done the troubleshooting on the web site, then it's probably cactus, buy a new one"
I have never been in favour of things that an owner can not repair, tinker with, even break if they wish. I look upon it as the worst type of corporate consumerism. Probably why I have a 25 yr old Honda CRV, runs like a dream, do all the mechanicals myself. If I break something I get a replacement part and off to go again.
5 yr warranty? I personally do not think that's a long time. 20yrs should b the standard when your talking major energy systems designed to remove ones reliance on fossil fuels power.
I’d say Midnight would be my next brand I’d look at.
Those classics are mighty nice, just not cheap.
I have too much other victron gear that if my SCC goes south, I’d just buy another.
When your 150/100 was running, did you notice hot temps? How often was it sitting near 100a charging?
I wonder if you throttled back charging to 80a it’d run a little cooler and last longer.
The max the panels can produce according to the calcs is 82.76A. and that's under perfect conditions that are never met in the real world. No it never got hot.
I have 2 MPPT & 2 multiplus (don't ask) the 2 chargers together charge a 4 battery in parallel 12v 280A/H battery bank. So neither are really working that hard.
Personally I am beginning to think, like many other consumer items there is a time redundancy built into these units, so they do fail at a certain point. Not precise of course but no longer built to last.
I was not offered any warranty extension when I bought nearly 4k of equipment. Not sure if that's because it is not available in Australia or because they don't like to offer that to customers.
