I live off-grid, quite rural & remote and the "grid" is over $75,000 away and staying put where it is.
I decided to go fully solar quite early on, immediately upon seeing the "on grid" quite from Big Power...
Being Ex Military & a retired IT Engineer, I knew the only way for me to go was to use Tier-1 equipment right from the start which led to my installing Midnite Classic SCC & at first I installed a Yiyen Inverter/Charger (budget issues) which I upgraded to a Samlex EVO within a year. Where I live, the conditions can be quite extreme and I had to have something that I could rely on because quite literally my life depends on a reliable system, half assed measures are simply not an option. I go to sleep every night knowing I'm good and don't have to worry.
I have never had any hardware issues with the Midnite Gear at all, and I use their MNDC E-Panels, Breakers, SPD's etc.... It's wonderfully solid equipment, I've been "inside" there and can easily identify the high quality componentry used, high quality PCB work and even looking at the soldering it's easy to tell it's all made really well to a high spec. I'm now adding another classic (150) which only needs 6x 395W Q-Cells to give me 94A charge amps. Running 24V btw.
My Samlex EVO is also extremely rock solid, I did have one electrical fault that resulted in a failure. They put a replacement unit on a plane and I had it within a couple of days. After they ripped apart the Inverter that faulted the problem was discovered and it was truly a "fluke" situation and they still took extra time to ensure such a fluke would not happen again with production models, even though it was a fluke. I've been into the Inverter guts as well and like Midnite, the componentry and assembly are very high spec... Again this is a Tier-1 Product.
Both Samlex & Midnite have excellent "professional" support and do very well across the board. Even so, there are always a few "sad sacks" who will never be happy for whatever reason (such is life).
If only we could get a BMS Manufacturer that could do the same at a respectable price.
I also want to add that there is an Ironic Funny in a sense (not for the victims of course)
As I stated above, I will be soon installing another Midnite Classic in parallel with my existing C-200. The C-150 will give me 94A from SIX 395 Panels 2S3P, yet people here are running at AIO's and buying a crap load more panels to get similar charge rates thereby negating savings... I got my new C-150 for under $700 USD and my panels (Q-Cells) for a very respectable price as well. Some folks (too many) forget how to use a Calculator and to consider their long term costs.
