Totally looks like what everyone else said.
You only charged your battery from 6 am to 10:20 am. You had a few clouds in this time, The rest of the time SOC was at or near 100% and PV power was ONLY going to loads.
You were getting around 50% at 10 am. This seems a bit low but not alarming...
I was watching that storm that day and saw the damage in that area. It does seem that the general Madison and Janesville area is getting slammed by weather events. I HOPE we are done for the year!
I like your ground mount idea! Tho I dont have any riding lawn mowers.
If the house panel is not in a basement, yes, it would be a lot harder. Opening a wall or perhaps just putting the inverter, and inverter fed panel right next to the house panel. Then it would be minimal wall busting for that part.
Yes, kinda. This would be approaching the concept of grid...
You would never have any doubled up connections with a series panel setup. Look up how that is wired. One of the panels neg would be going to the other panels POS. You could probably do this with the existing MC4 connector on the panels.
Check youtube. I have no idea what is in there.
This doesnt sound like a battery problem to me tho....
It sounds like the charging logic cant see the battery.
It could be anything at this point
I think it will always say that. Its just a communication thing. The switch disengages the "genuine" protocol and inserts a more generic "modified" pylon tech that causes less trouble. That is the way I think it goes anyways.
You have a cell that is very unbalanced. It is pushing the pack SOC to 100.
The bms halts charging and sets soc 100 because you will overcharge that one cell if it doesn't.
Is this a new pack or an old one?
How can imbalance kill cells? If a cell isnt going past its HVC and LVC what difference could it make to the rest of the cells?
Or are you talking about a couple batteries that all had imbalance issues with them eventually?
That would be to follow sunshine_eggo's advise and find out what the problem is. The math does not add up! We can NOT help or advise you if we do not know where to stand.
Love your attitude. You are certainly in the right place with that great attitude and interest in solar.
Most everyone here will talk your ear off if we think its a worthwhile endeavor.
NEC states that the grounding must not be broken by removing one. So I would bet that is not going to fly.
I am interested in what Tim has to say on this.
Thank you Tim. You are a wonderful resource for us plebs.
I have been using lead acid mode for my LiFePo4 batteries since november and the Soc has never been anywhere but between 47%-72%
Never have I registered a SOC lower or higher than that even tho I have fully charged and discharged my batteries many times.
So, I was pretty sad with my wiring when I discovered that it looked to be aluminum. It turns out it is 1930's pretinned copper. I found this out after changing some outlets and switches.
The range line seems to be the same pre tinned copper tho I have not messed with that line/ scratched it...
You just need to move the inverter to the other side of the shunt. ONLY the battery should be on the B-. Everything else should be on the P-
Charge controller and inverter should be on the same side, Battery should be alone.
Hoping someone else can help here. Mine came with my combiner box.
It absolutely can when you disconnect a circuit under load aka charging you batteries.
MC4s would be energized by the sun OR panels wired in parallel. the solar charge controller would be the load.
If you have a pv disconnect...
