If they have a butler but still a generator interlock plate, not a full whole house standby with an ATS, their priorities are a bit messed up.
Maybe they finally upgraded and that’s why these panels got rotated out.
Also one thing to keep in mind 2200ah of LiFePo is about the same as ~3000ah due to usability limitation of FLA and efficiency gains of LiFePo while charging.
It’d be best to plan for a robust system one for one swap, but you maybe way over building the new bank compared to your current use...
So 64 280ah cells at say $90 is what $5700? but replacing an inverter and some lightning protection is too costly??
Btw check out this thread for some other 8p8s build wisdom...
In their “loop” video Dexter uses romex, but they recommend SOOW with ferrules.
Also that 6awg is for max power assist of 70a. I can’t imagine victron requires the minimum awg as the max awg of those spring connectors.
I’m gonna try and see of 12awg solid slides out of the spring on my 24v3k.
Just stay away from GFIC with Arc fault.
If you’re looking to add say a 70a load center with say a Square D QO breaker.
Arc fault protection does not like to play well with large brushed motors, you know the large motors that constantly arc when running.
GFIC is all you’d need.
My idea was to keep it as a “MP load center” with outlets, 15a duplexs with GFIC and TT30 with GFIC breaker, so I could use it at home in the winter to power our furnace during a quick winter storm.
The solar input and combiner box most likely will remain separate.
You are right I’m now in the process of laying things out on plywood dry fitting things for layout, the MPII is a heavy beast, then another 20-30lbs of Lynx, load center and outlet boxes, that even without the MPPT.
You’re right, lightning wants to find ground ground, so if there is a direct path to ground from an array or and metal structure straight down, it won’t travel back to your panel .
This is the same for the radio tower, send it straight to ground not back to sensitive equipment.
There are certain circumstances where they may not current share load evenly (even with proper wiring) so as long as you don’t need to exceed one BMS worth of current you’ll be fine.
Capacity tests are just as useless as QR codes fake or real and “test reports”.
Everything is grade b anyone saying otherwise just wants to feel good with their purchase.
Not to pry, but any chance you were employed by Orsted? It’s crazy at the challenges they’ve been facing here in the US and the write downs they’ve incurred.
whoops, I’m sorry I miss read your post.
If your system is all in parallel, just verify proper wiring for current sharing and also make sure you hit 100% charge routinely, otherwise you may lose a few AH.
