This will be a bit of a long story so get yourself a drink first.
As many of you know I have a DIY system that is working every well for me. Its a Aims 24v 6000w inverter with 2 EPever 100a mppt controllers. I have all of it maxed out around 5000w worth of solar. This is powering my entire life from my well to my RV and I have had no problems. The only thing I run into is needing way more batteries than I can afford right now. So I crape together what I can to get more little by little, I'm even building my own now thanks to will. My new neighbor saw what I was doing and wanted to try it too. He got with me and we worked out what he would need to get started, then he ignored many things I told him. In the end he when with AltE store prebuilt 48v system and big battery. His system is a 48v 8000w outback inverter with 2 80a outback controllers. He has 7.9 kw of panels with only 20kw of battery. The problem is his system has not been running right, he is always having to call AltE for help. first problem(that has not been fixed) was that they system was telling his is batteries are low. Yet the batteries have there own shunts on them and they say they are almost full at 57v. AltE keeps telling him to reset everything then the system will learn the batteries, so far that has not worked. Even now they system will throw event codes that the batteries are dangerously low when you look at them and they are over 60%. Next problem is the mppt never pull in the full amount of the panels even with clear skies at peak solar time with batteries at 50%. AltE tells him they won't pull full unless there is a load on them so turn things on and they will ramp up. My system will pull full all the time until the batteries voltage gets to high, even with a load his still don't pull full.
This got me thinking why is it that he paid way more for his system yet it is not working flawlessly like my Diy? I'm wondering in an attempt to stay relevant did the bigger names in solar over engineer there stuff? For outback to make this stuff all work together you need a $425 MATE3s controller box and a $1225 GSLC box with bus bars and circuit breakers in it. All I had to do was connect them all to some 250a bus bars off amazon and boom they all work. I don't even know how to connect my 2 controller together but they are still working with no problems. He has been getting discouraged about all this he spent over20k and still has to run a generator just to live right now. The only time I need my generator is when we get more than 3days of rain, other than that I am full solar.
What do you all think of this?
