15-23v panels and yours are 46v. That's not gonna work.
Understood, worth a shot, would I get more than 120 watts if I used that fake mppt ? Again I'm just guessing, kindly forgive my lack of knowledge, I'm here to learn15-23v panels and yours are 46v. That's not gonna work.
Excuse me ? Lsc ? , meaning it will only give me power at the 12v that my 2 soon to be revived batteries are ? And nobody really answered me about refilling distilled water, do I need to empty the fluid inside the batteries now or just add distilled water to the brim and plug the power I cables back in and hope for the best ?No, you'll get the Isc/amps at battery voltage... if the controller doesn't just burn up.

When you open the caps on top and look inside you'll see the tops of the plates. You want to add water until the plates are covered by about 3mm or so. It doesn't have to be exact to the 0.00000001mm in there.
Not “ell ess cee”, but “eye ess cee”, the short circuit current. You will actually get somewhere between Imp and Isc, but never more than Isc at your battery voltage.
Thank you all and how do I bring my 2 batteries back to life (and since no one actually answered that question, can I assume that it isn't recommend ?) Pop open the caps on my batteries and top each hole with distilled water until the top ? Or empty it first ? And I think I'm supposed to give it a high charge to convert the water into acid.. but my battery charger won't really put out more than 10 amps......
What a trainwreck
somewhere near the front it was established the batteries were "German" Gel
looking at the OP video confirms it, the top of the batteries are as smooth as Barbie and Ken's groin
I'm afraid of what happens next as the OP attempts to take the "caps" off his batteries
Totally agree, however if the cathode inside the battery are crystalized, not much a slow charger can do.... However no harm in trying and I I have no idea how to add 3mm exactly....Yeah, all this talk of caps and stuff addled my brain, if they are actually sealed gel then then they're dead
PWM plus an over-sized panel has probably sent them into the next world
A slow charge might bring them back but ...
Sorry , on the battery it is WRITTEN Germany but FORD cars are USian cars right ? Built in India/Bharat however... These batteries are as likely to be German as I am to sing a duet with Justin Bieber....What a trainwreck

I did it before daylight so I couldn't see Inside the hole, so I just filled you the syringe to full which was ironically 6... Squeezed it halfway to each hole so I put I guess 3 cm ??? Hopefully that is 3 mm wtv that is, unless he meant 3 ml....Repair function on the charger? Yes please!
Don't worry about exact measurements. As long as the plates are under watet and it's not spilling out the top you'll be good. Leave the caps loose when you go to do the repair charge so if there is any gassing it can vent off.
I put the black little black cap on and not the bigger plastic thing.. sorry I didn't see your message before I did that but wouldn't letting anything (IE gas) escape be bad ??? I believe I should let wtv gets converted into gas go back to fluid after use....I did it before daylight so I couldn't see Inside the hole, so I just filled you the syringe to full which was ironically 6... Squeezed it halfway to each hole so I put I guess 3 cm ??? Hopefully that is 3 mm wtv that is, unless he meant 3 ml....Well I used my electric fan on those 2 batteries until 1500 (3 pm) it's still daylight outside so I hope I was using wtv solar power was coming in, and not the electricity that I used to charge it with... I'll find out when I wake up before dawn and turn the inverter back on.. oh and the electric fan didn't just stop, the inverter started chiming like an angry vibrator
Note that the electrolyte (battery acid) expands as the battery charges, so you''ll want to ensure the plates are at least just barely covered before starting charging, but not top them off until after they are fully charged, lest the electrolyte expands and overflows the cells.Evaporation is normal, especially when cooking all the gunk off the plates, hence needing to add water occasionally and looking down those holes to make sure you have enough in there. You can't just guess how much you'll need, it's a distance estimate, not a volume estimate. Would a diagram help make that make sense?

When the water boils off the plates get exposed and grow funk while not being able to do any work. You want the caps loose or off so that water evaporating has somewhere to go and doesn't find the weak spot in the battery shell and come out there.
When the water boils off the stuff that makes it into battery acid gets left behind and when you add water back in the stuff gets re-dissolved turning the water into electrolyte. That's normal, don't panic.
Let the repair cycle run, check your water and run it for another cycle just to make sure all your plates are super clean inside. Then charge it up all the way and give it another water check. Hopefully this process will get some capacity back and you can make the battery last longer.
You may want to seriously consider a LFP battery. Twice the capacity for half the weight, no maintenance, no fire risk like you see in Li-Ion batteries, much longer lifespan, better value per dollar over lead.
12.09v this morning fan spun for 5 minutes, and during daylight time.. less than 2 minutes at this moment, 1 hour till noon voltage is 12.71v.. turned on the inverter, plugged in my tall standing fan and the inverter started beeping annoyingly, the fan didn't stop spinning until I turned the inverter off, Soo not enough water ????Hhmmmm..... what was the battery voltage holding at after you ran the repair cycle?
