bump : ( help

My van is outside in UK Not much sun past 3 weeks just rain. I run a fridge off my inverter only Today I noticed battery is flat. I can’t charge it. Got these errors and chg mos and discharge mos are off. My mppt got an error as well - battery over discharged. Any tips how could I resolve...

is it possible to connect my laptop with the daly "BMS monitor" app or other BMS app via the bluetooth connection i already own to my 4s 12v daliy bms? i successfully connected to my phone app and programed it. but i cant seem to change the "CURRENT WAVE" function which supposed to allow my bms...

Thank you for all your help. ??????

Tested the bms with my dc to dc charger and my inverter/charger voltage drop happens on all at the BMS

So the voltage drops at BMS P- side. I guess when I shorted it by accident caused some dmg huh?

I haven’t bought that one yet. Thanks for the heads up I would have messed it up without you

Yeah just googled the panel spec and it said on there website it’s 12AWG.

First of all thank you for the lengthy reply. I’ll try to start measuring the connections. The manual is useless. The best explanation I found was by forum members. I already got the mc4 3-1 connector. Solar wire is 12AWG factory fitted 4mm2? Changing it would be extremely hard considering...

I moved bulk charge recovery higher by 0.1 and float by 0.1. Rebooted the system and it’s bulk charging with 14.14V 5.24A I multimetered terminals on the mppt and it reads 14.14V Multimeter battery terminals 13.35V As soon as we move 0.1 higher and we reach float charge it will slow down...

It’s back to float charging^^

A minute ago mppt turned red, battery reached max battery voltage was (14.17V?) I rebooted after I stopped panicking I can confirm it’s boost charging now and battery voltage increased to 14.19V BMS reads 13.3V Multimeter on battery terminals 13.36V Battery has never been fully charged with...

Thanks for reply 14.38V was in the morning when I messed with bulk reconnect to see what it pulls. After moved it a bit it kicked in(stopped since) it was the charging voltage in bulk mode Right now it’s 13.44V and float
