I'm a total novice regarding this stiff. My question/title assumes that's what's happening. I've read many posts on "flickering led lights," but none have really helped me understand the issue.
I have a ~ten year old outback system, don't have the model number atm, if that matters. Two inverters that I believe are ~3.6kw each, 7.5kw solar, and ~70kw battery bank of rolls lead acid batteries at 48v. Off grid.
Randomly over the years, I would get the light flicker, sometimes when starting the AC or well pump, sometimes they wouldn't flicker when starting those, and sometimes the lights would flicker when minor draw things would run. Also, all of my uninterrupted power supplies in the house would also flip on sometimes, when certain electronics would start. A few years ago I purchased a Miller 252 mig welder, (a big transformer style welder), and whenever I would be in my shop, which is on a separate panel from the house, if that matters, welding, it would flip on all the uninterrupted power supplies in the house and make all the lights flicker. Everyone in the house would get quite annoyed, and you can probably imagine what it was like when doing dozens of tack or stitch welds, just a few seconds between each. I sold that welder and bought a smaller, inverter style welder, which got rid of that issue.
Running that big miller welder only drew about 2kw, so I had plenty of power, but I don't understand the issue it was causing. I have wanted to get other tool, that I know will draw even more power, but haven't because of this issue. I am now looking to replace my system to have greater output and with a lithium bank. I have been thinking Victron, It's basically going to be several of the Multiplus 2 5kva or 2-4 of the quattro 10kva units. However, I watched Adam De Lay's video on youtube of him setting up two multiplus 2 5kva units and tehn testing them, and when he started his AC, the lights flcikered.
Is there no way around this issue? There must be, because I've also watched videos on Victron's youtube channel where they're setting up massive systems for businesses, like a saw mill, and I can't imagine they're having those same issues and just dealing with them, after spending hundreds of thousands of dollars? If there is a definitive answer as to why this happens and how to eliminate it, I would be very happy to know, especially before spending tens of thousands on my new system. Thank you.
