I have my system multipus 2 with cerboo GX, working properly, but the pytes batterie (4 x E BOX R4800 type c in parallel) do not show up in the device list, everything is connected to specs and working fine, including ess.
Any suggestions?
asked
Why is my set of 4 pytes batteries not showing up in my device list
The obvious things are - is firmware current? Are you sure you have the right cable? Is everything properly terminated? Are you using the correct CAN port?
If a battery does not appear, it is usually something basic relating to the above, or something was missed in the battery/BMS setup.
The firmware is current, the cable is a canbus cable from Victron themselves, the can is terminated on the cerbo side and in de ve.bus in the MP2, next to the cable that communicates with the batteries. Dynamic cut off is set at 47 v and float at 53,2.
The battery has nothing to do with vebus. Terminators are not used in vebus either. It should be connected to BMS.CAN.
Make sure you follow this setup doc exactly.

i am sorry about the float and dynamic cut off , has nothing to do with this.
i do not know the firmware of the pytes ebox R4800 batteries, they are type c, the bms can is connected to the ve.can of the cerco and terminated. The batteries are connected with a normal cable to de ve.bus in the mp2
I set switched the SVS off, the other DVCC settings were ok.
You mentioned v18.1 on cerbo or vrm, where can i find it?
”The batteries are connected with a normal cable to de ve.bus in the mp2”
What do you mean with this? Batteries bms should only be connected to cerbo bms can bus, nothing else
Sorry, ik bedoel de koppeling tussen de cerbo en de mp2 gemaakt
Dus de speciale bms can verbindt de batterijen met de cerbo gx en de cerbo gx is gekoppeld via de ve.bus met de mp2, en de master en slaves zijn gekoppeld van link1 naar link0 enz
Ah ok
De bms can kabel verbind de batterij bms met de cerbo, maar let op er zijn 2 verschillende type kabel hiervoor type A en B welke voor pytes nodig is weet ik niet, ik heb pylontechs
Volg hier alle instructies voor pytes batterijen:

Ah okay The BMS cable connect the battery BMS to the Cerbo, but note that there are 2 different types of cable for this, type A and B, which is needed for Pytes, I don't know, I have PylonTechs
Follow all instructions for pytes batteries here: https://www.victronenergy.com/live/battery_compatibility:pytes
Ik heb alles gedaan volgens het boekje de goede type b bms can kabel gebruikt, de 500 kbit/s ingesteld voor de CAN-bus, de firmware van de victron spullen geupgrade, maar ik kan de firmware versie van de pytes R4800 type c (met de 6 dip switches allemaal uit) niet uitlezen ook m dat de batterij niet in de device list verschijnt, ik ga nu met de tool van pytes zelf e.e.a op de batterij bekijken, maar moet even wachten op de kabel, de ondersteuning van pytes is teleurstellend, een zwart gat.
er is een verschil tussen de CAN b kabel van victron en wat de pytes nodig hebben zie ik in de victron pytes manual
pin 3 is gnd en moet verwijderd worden! gebruik ook geen terminator
translation:
there is a difference between the Victron CAN b cable and the pytes connection if found in the manuals, remove pin 3 (GND) from the RJ45 plug, also dont use a terminator
ik heb de ground verwijderd en de terminator verwijderd en het resultaat is hetzelfde
Ik heb een usb rj45 kabel gekocht en Hyperterminal van Pytes geïnstalleerd, ben nu klaar om de firmware bij te werken, maar ik word een beetje bang vanwege dit scherm.
as said double check cabling specifically master to slave bat as well as any dip switches.
The battery with the empty link port 0 is the master battery.
Have you followed the instructions in the setup link above to the letter? After that, play around with the DIP address. In my particular case, using other brand batteries, the documented address never worked. I had to guess another address.
