I have Dyness DL5.0C compatibility issue with Victron inverter.
 

Just installed a new off-grid system with Victron Multiplus II 48/5000/70 and two Dyness DL5.0C. Both are completely new, just purchased (Victron with the newest FW). The Dyness DL5.0C was manufactured on 17.06.2023, FW V95.1.
I found in the documentation (about Victron and Dyness integration) what some data under menu DETAILS (what is planned regarding the document to implement) must be displayed, but actually they are missing. There is no such menu at all in the new system. It means battery BMS is not sending them to Victron.
Details must include: cell voltage, max and min temp, number of modules, capacity like described in your documentation.

My questions are:
1. Did DYNESS implement sending DETAILS to Victron like described in attached documents?
2. Maybe DL5.0C has old FW and needs to update FW to newest one with all data transferring from BMS DL5.0C to Victron?

    I know the same story with another person (another installation) with battery DYNESS DL5.0C manufactured 06.2024 and newer FW (V96.1).
3. Can you send me the newest version of the installation manual for Victron and Dyness system?

 

Regarding answer of Victron support, it is Dyness responsibility to send all data to Victron and they are missing.

Hi,

My Dyness 4x parallel DL5.0C batteries system when it hits 50% drops rapidly. We recently added 2 to our existing 2 batteries.  Can you think why this might happen?

What percentage was the battery bank at before you added the new batteries? It might just be a balancing issue. Can you tell us how they are linked together? Do you have comms going to the battery bank as well?

Hello!

Wondering if you could help me with BMS communication between my Dyness BX51100 & Mecer SOL-I-AX-8M2, I have tried various dip switch settings and RJ45 Cables, Currently made a custom cable that does the pin cross-over but the Inverter keeps complaining about no communication to the battery. Any help would be appreciated!

Hi i have installed 2 additional hv51110 batteries to existing 4 batteries in series. I have some problems since refer to graph .please advise

HI I WANT TO CONFIGURE BMS OF DYNESS BX51100 WITH SOLAX X1 HYBRID LV INVERTER. COULD YOU PLEASE ADVICE PROPER BMS CABLE CONNECTION AND BATTERY SETTINGS FOR INVERTER

IF POSSIBLE SHARE DETAIL AT 0334-3218625

THANKS

Good day,

I believe I am also battling with a firmware issue between my 4 batteries. Is there someone from Dyness still on this group

Hi, have issues using batteries with SunSynk inverter, problem identification is loss of BMS, is there a set pattern for the front mounted dip switches when using 2 or more batteries, thank you.
