Some news..

Thanks to @Tejota I change the communication cable to the slave, and send the command to charge and seams to work, maybe the command received by the master it's not replicated via parallel board.

i will buy another communication cable, and try with 2 communications cable.

Thanks guys!

Sorry, @coulumb , hahaha about changing your name!, in Barcelona we have a monument for you :D At this moment, there's no sun, the battery is discharging at 5A, I change to utility, send the command MNCHGC020 and starts to charge at 20A, wait 1 minute, send a MNCHGC002, and charges at 2A, i send MNC...

HI Columbus I have 2 PIP4048MS working in parallel with firmware 72.70, working since 2018. Usually I charge at night using the utility at 50A using the master (MUCHGC050+crc) and now I want to use the slave charger to charge the batteries at 50 A additionally to the master. I tried to send MUCHGC15...

@weber, @coulomb, thanks guys, Sorry i make a mistake "lithium ion", and understood that also it's not so accurate. i will say "18660 batteries" :-) I will install the PB version, and set the 29 parameter to 46.2, that means 3.3 volts * cell, it's ok for now... but many people set to 3V the cell cut...

Hi! Finally is here!. I have to update the firmware to start my installation, i want to install the 72.70b Firmware version, but i don't know if i need to install the PB version or the LF version.

@coloumb, of course, you are right, i use a battery 48vdc (13s4p 18650 ) and the display turns on, and the PIP works, first step acomplish with your help, thanks.

Sorry, if this question is too silly... i spend a lot of time looking for the answer and i can't find it. I have a new PIP4048MS, and i want just test it without batteries and without PV input, i connected 220v AC input, and when i press the button to power on, nothing happens, it's normal? Thanks g...

@Northland, i like the idea of your balancing, and i love your videos too.

Do you have plans to show how it's made your arduino bms?

Thanks for your work!

Hi Rinaldo I'm still thinking about balancing, there are people that say it's needed a BMs, other people say it's not needed (jehu garcia) and talks about bottom balancing, another guys talk about top balancing, in my ignorance I can't understand why there so many criteria difference, but I will try...

Hi, My name is Joaquin Custodio, from Barcelona, Spain. I'm working in an DIY PowerWall exactly like this www.hbpowerwall.com from Peter Matthews. following his path, i bought a pip-4048MS to use with de 14SP80 18650 lithium 200aH, Peter is using PCM60X to charge the packs using Solar.
