Hi all. I have an off grid set up with a victron 48/15000. Up till now I had a single stack of pylontech batteries and everything functioned fine.
When adding a second stack and wiring up the LV hub to both stacks, the hub keeps getting a red flashing light error. The dip switches are correct and all wiring is perfectly done.
Each stack connected independently works fine but when put both through the hub they don't work. The error is also present if the hub is not connected to the colour controller. Does anyone have any ideas?
The sellers puntoenergija have no idea. Not much documentation online either. Pity cause pylontech batteries are very good quality.
