Wow you’re not kidding, they are all messed up! Let’s just say I am not known for my abilities to wow people with numbers. (Will fix) My rv/trailer exhaust fans are running!! My VictronConnect is up and going! You all ROCK!!! Thank you thank you! (Now back into the office and to my “real...

I recently purchased a vintage travel trailer that I THOUGHT had a decent solar setup...After closer inspection both batt's were swollen and the CC was kept in the same compartment as the lead-acid batt's(just one of many bad designs). COMPLETE DESIGN REDO I will use the original CC(moved to...

I’m being tripped up because of the misunderstanding of the vernacular. Crystal clear now folks! Thank you so much, the Ruby is up and running because of this forum so thank you!!!!

MrSandals, you are correct. The BMS did not accept a big jump in value change but did accept small incremental changes. Hence after 4 or 5 writes to BMS I ended on 10100 for my Batt Undervoltage.

The first day it was worked hard for 7 hrs straight and consumed only 40% of the 460ah batt. This is why draining the remaining 60% in a much shorter time does not make sense to my ignorant mind. All of the conductors are 4AWG, longest length is 18" roughly? We are running a tiny compressor at...

400 I have to agree with you, after reading I think the system is operating fine in its current state. Seems perhaps I need another component for it to perform in the manner I first intended.(honestly right now I'm just guessing but thankfully I know the answer is here some where:-) My...

One more just for giggles

I will institute all the changes this evening, thank you ?

So it’s not the power going through the BMS but how the power is being produced (from the x2 power sources) Since that 140 total amps is being divided the BMS can handle it just fine, yes??? And ya I get the fact that a second bank w/ its own BMS would be best but overkill didnt even suggest...

I have a problem and I have no idea where to start trouble shooting the system. Simple 24v Setup: #4 200W Mono panels feeding into 40amp Epever MPPT, I'm just using the lifepo4 setting which may be my problem? Overkill 8S BMS Giandel 4k/8k pure sine inverter Victron IP22 charger (All new...

Sorry for the mess

I followed instructions exactly and everything seemed to work great. This is the first time noticing this problem.

I’m wondering if I need to setup the MOES differently?

main terminals = 13.96 2 cells = 3.49 2 cells = 3.51 BMS reading:

For now the draw on the system will be the Keurig, occasionally charging iPhones, ipads & a M1 laptop. All the lights have been changed to LED. I am also adding an insta-hot hot water heater for the wet bath I am working on(I am in the middle of the bathroom remodel now).

It did this right from get go(before batt’s were cold), I cut power at BMS because when I plugged my heater in I noticed a draw from the batt’s instead of shore power. Doing this allowed me to run off shore power but I don’t know why/how. Obviously I can’t have an either/or situation going on...

12V 4s 120a 280ah, Victron MPPT & Shunt, Giandel 2200 inverter....... Discharge overcurrent is thrown when the Keurig is used, at the outlet its drawing the right amperage (12) but the BMS and the shunt say its pulling 140A. Happens on all the outlets, my shop vac runs but is pulling 80A...

For my battery undervoltage protection I just tried the value 12345 12346 and it was accepted!! So is this kosher? Will it ruin my cells, guys I(obviously) have no clue and am learning as I go but here so will leaving it at this value ruin anything? I tried to go down to 10k 11k and it would...

I top balanced my cells and then hooked up the BMS. Put in all the parameters and naturally did one wrong(Battery under voltage). I hooked up the inverter(Giandel 2200W) and the heat gun worked fine til the error was thrown, batt under voltage. I now can not change the parameter, everything I...

I have emailed back and forth with overkill and no answers at this point.

This was suggested by overkill so I did it ?‍♂️

Funny passwords… you killin me

my apologies, trying to power thru a migraine....yes you are correct I was referring to the 3.2v Doncan cells. (I knew I needed to buy 4 for a reason ?) I looked over a few BMS setups the other day, I seem to remember the Overkill was top of my list (if not top two, I prefer to buy once and be...

I know the cells were well over 95% last time I checked at the posts(3 or 4 days ago) and when I tested the heat gun it was for seconds. That being said, I will get the voltages in the morning and post. Also yes MisterSandals, thats a great point, will try and edit then save on laptop.

yikes.....Well I guess the Keurig Express (perfect size) has gotta go and the French press:love: is coming back. A lesson hard learned but will always be on the mind when we want to add something. Thank you all! Side question, Are my settings ok?? generally speaking ?

I will try and get as near as possible, it has not allowed me to set it at 10000 or any of that ballpark.

I was forced to change the value in small increments down to 10100/12000

LOL ok uno momento
