All, since now about 1/2 year i am plagued with a 3 phase installation (3x Multiplus 48/5000 and Venus, Pylontech Batteries) which quite often goes in a "havoc" mode where the Inverters start to go haywire, invert into the grid without observing their setpoints. Although it is very clear this happens in the Inverters (i monitor the Ve.Bus and can see that the setpoints given by Venus are correct), i am a bit desparate, obviously. So one possible solution to circumvent the error might be to control the Inverters direct.
Victron seems to not give support on this, so i ask here - does anyone have experience with this ?
I have the Pylontech CAN protocol sorted out and hacked, so i have all in need from the battery side, and i use an energy meter connected via Ethernet - the only missing link is to use the Mk3 to correctly deal with the Multiplus Inverters. I think i know about what to do, and i get all active data from the VE.Bus by just listening to it - but if there is someone out there with experience, please let me know.
Also i offer my knowledge and insights if someone has similar issues, wants to eavedrop on the VE.Bus or needs help receiving Pylontech's CAN data (in parallel to a Venus for example).
