But I have fixed it! All readings from the harness are what they should be

So for the past few days I had been seeing strange readings for the cell voltages on the BMS app. Sometimes a cell would have a very high voltage out of nowhere. I thought it was a problem with the app so I ignored it. Today, when charging with my Mppt suddenly the BMS would trip from low cell...

I have this MPPT, but not the BT module. Can you set the parameters for the "user" profile using the app? That would be my only reason to buy the bt module. Are there any other reasons?

So after a few days, I can report back on this. (We didn't have much sun so couldn´t really reproduce until now). The new settings seem to have made the BMS less prone to switching charge off (only saw it happen once, and probably because my cells are out of balance). Now it charges the battery...

Your guess is better than mine LOL. I will be setting these tonight and see the behaviour tomorrow (It is quite hard to set since I have to crawl inside a cabinet in my van) My controller has load ports, I don't use them. Should I? Why is your "equalizing voltage" so low? I take it that it...

I have made the changes. On the MPPT, these are the parameters I can set: And this is how it is set for the current mode (LI battery) (Not sure what the '-' means, also not sure how to replicate that in the User-defined profile since I have to give a value):

Well my BMS doesn't seem to have that option. These are the only related options I can change:

Thanks I will try this ASAP. However, I don't see any "recover" option on my BMS app (is this the voltage at which it would alow charging again?) My BMS is a DALY with bluetooth APP

So I noticed my BMS is having a strange behaviour when the battery reaches full charge and there is strong sunlight. My BMS is set to stop charge current if a cell goes above 3.6V or the battery voltage goes over 14.4V So what happens is that when either of those things happen (it is the 3.6V...

Hi everyone. "Questions in the end, feel free to answer only some. Disclaimer: Me be noob" I bought this MPPT (40 A version) (Branded as WEIZE but apparently made by SRNE, the Rich Solar one also looks very similar), which appears to be very decent for the price, however I am having a little...

Hi everyone. "Questions in the end, feel free to answer only some. Disclaimer: Me be noob" I bought this MPPT (40 A version), which appears to be very decent for the price, however I am having a little trouble programming it and there isn't much info online. According to the manual, these...

Sweet, I got it all wired up already, just need to mount the panels and charge then!! After the trip I am looking to go for your method (using laptop supply): I like this because it is cheap and I have two old laptop power supplies around. (not looking to spend much on a charger I will use...

All right people! the wait is over, my panels and BMS are in!!!! I have been reading on the top balancing subject, as far as I understand, the only benefit is that it will maximize the usable capacity of the pack. The thing is I have three days only before my first trip (2 week trip) on the...

LOL! damn dude chill! But you are right, I tend to do that haha. So you know what you are right, I'm just gonna enjoy Christmas, stuff my face with food and forget about my battery. And when I get the BMS I can get to work and finish the job right! Thanks for your help PS: do you think I...

Actually my panels are arriving today!! (480W, and I have a 40A MPPT) Do you guys think It is okay If I charge using solar WITHOUT BMS?, just to check everything is working fine. I would monitor voltage just to charge up to like 50%

Thanks I will read up on these for when I get my BMS. It has been ages, I ordered one of the "smart" daly bms (150A)

I was under the impression that bottom balancing was the way to go for LFP, is it not? In any case, parallel top balancing would mean to charge the pack (with MPPT) up to about 3.6V per cell and then connect them in parallel for a few hours? So glad to hear that! In that case I will just wait...

They were all 3.23 V and now they range 2.98 - 3.00 V Ok so no damage can happen for letting them sit a week at 2.98V ???

So a couple days ago my 3.2V 230 Ah LiFePO4 cells arrived, but my BMS didn't. I decided to assemble the battery and with that my whole system, knowing that the battery would be running without a BMS, and I would have to be careful. Now today when I checked the battery I noticed that the voltage...

Thanks a lot for your responses, really. I am beginning to understand this. is the .85 the inverter efficiency? I know that there is a 120V inlet right next to the gas inlet (on the outside of the van) and when you plug that in, the inverter is bypassed and now the 120 V outlets go directly to...

Awesome, thanks for all that info. So I filled everything out and this are my results: So what I understand is: -I should check my inverter to see that it is at least 800 watts (I am assuming it is, since it is HUGE and must have been used for intense ambulance stuff) -My 230 amp hour...

Hi there, I know another newbie that wants solar in his van and has no clue... In reality, I have done a lot of research but am having a little trouble putting all the information together to decide what components to buy, since apparently everything is interconnected and I have to make all the...
