Multiple charge controllers, complication with dbus-serialbattery #2

Hello,

we already had contact in the victron forum. I would like to use the driver to integrate three charge controllers. In addition, there seem to be problems when dbus-serialbattery runs in parallel.

Adapter: image

How can I support you, do you need more information? I would also be interested in how I can cleanly remove the driver from the system again.

I'd be happy to hear back from you.

Really useful project. I have Raspberry Pi Venus, with Victron 100-50 plus 2x Epever Tracer 6415AN. So hoping to get this working. Im using dbus-serial battery, Jk BMS which is good with DVCC, to control the output of the Victron SCC, when the battery is high. Being able to limit or turn off the Epever's would be great too. The 6415's have a problem with Lifepo4 BMS, if it disconnects Charging; they then put a high voltage, sometimes near solar panel voltage onto the 24v system. Im using a Victron Battery Protect on the loads, but its HVD is fixed at 32v, and a bit slow operating, so a few small items have been blown, that cannot tolerate over 32v. Now on 7S (310Ah cells) where over voltage is lower, often around 30v, and panels now in parallel 40v. With 8S overvoltage was higher. Maybe need a second Victron Battery Protect between the Epever's and the 24v system. i am setting the chargers to 23.6v max = Bulk & Absorption for Victron = Boost & Equalisation for Epever. Epever recommend using both those, at the same voltage.
