Is it possible to connect it to a regular plug like the below so that I can connect it to a socket when ironing?

Cc: ojeysky, ceaser and others . Thanks in anticipation
I guess valto has said it all. Your home socket is AC voltage and current while the iron expects DC voltage/current. That plug is rated for 13A yet it's likely your iron will require more than a 13A DC current. In short if you love that iron no try ham o, the smoke will shock you cheesy

IYGEAL:
Yea, I'm aware of the bolded. I did because I set it below that previously but it was still seemingly maxing at 26.4v. So I set it at 29.4v and stayed around to monitor it so that I can stop charging when full, but it was still the same.

Also, while discharging, it discharges gradually from 26.4v but rapidly from around 25.4v to cut off at 23.7 (as I set it).
That's normal behaviour of lithium it has a fairly stable charge/discharge curve between 90 and 20% capacity.

Cell imbalance may be the issue but I also suspect the internal CC of the inverter. I got this Bank from a reliable source, a DIYer and he has it arranged with the BMS. I'm still starting this lithium journey but my arrangements are giving me serious headache.
Arrangements of LFP is the easiest thing just the normal series/parallel setup. Yes the DIYer may be good but the cells may have gone out of balance. However see below

At 26.4v, it appears to charge but no significant increase is witnessed. It can go 26.5 to 26.7 and back to 26.4v on no load.
For it to be going up and then back down it's a reaction from the BMS when one of the cells hits the high cutoff voltage, it triggers the BMS to stop charging for that cell voltage to come back down and then charging starts again. The circle continue like that.
What I can suggest is that when the BMS trips and stop charging disconnect charging source and then try to do a capacity test to see how much juice you get out of your battery. If it's at least 90AH then you have no balance issue. The cells were just full

Do you suppose 150W x 8 is not enough to charge the 100AH 24V Bank?
It all depends on how fast you need it to get fully charged at 20A charge rate approximately 5hrs charge is required from low to full. Your array size is 50A but assuming it's well positioned and only dedicated to the battery then it should be able to push in an average of 20A into the battery within 5hrs a day (10 to 3pm).
Take note of the assumptions though.

IYGEAL:
Thanks. I went back and read the old messages and got the parameters.

I set both bulk and float (since I can't disable this on SMK Hybrid) at 29.2v.

Still, the battery couldn't charge beyond 26.4v all day. The inverter reads 120v as minimum voltage, so I fed it 1x8 150W panels connected in 8s1p arrangement.
Bros 29.2v for LFP chemistry is too much, please go through that previous thread to see why. As to your voltage, was the battery still charging at 26.4v? If yes then no issues your panel capacity is not large and maybe the battery has depleted hence will take some time. However if it was not charging at 26.4 and you are certain the battery is not full, then you have cell imbalance issue
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by ojeysky(m): 8:29pm On Feb 10, 2021
IYGEAL:
So I acquired a lithium battery bank of 100AH 24V (8 strings of 3.2v 100AH cells) and to use it with a 3KVA Hybrid inverter.

Having seen the inverter's control parameters, I'm curious as to what voltages to set for the Bulk Charge and Floating Charge, especially the floating charge voltage as LFP don't like staying 100% charged for long periods. There are several settings for equalisation which I have decided to leave at default.

Please I need inputs from experienced LFP users.

These ones may not work, especially the second picture. I think you'd need CC-USB-RS485-150U. This is based on the experience I had with EPEVER TRIRON3210.

Yours may be different though.
This seem to be unique to epever. However I am certain the first pics will work and reading the datasheet of the second pics it could work as well. Anyone will either should quote me, I don't mind trying out either of them
