After some clarification of the behaviour of the RS when connected to pylontech batteries.
Lithium pre-set is selected which in turn changes the remote mode to BMS, which would be logical.
DVCC is on on the venus device, pylontech detected over the can bus etc...
The MPPT RS shows networked operation as external control and BMS,
yet the RS stays in BMS off mode and will not charge.
Switching the remote mode to remote on/off with the stock jumper installed in the I/O plug enables charging?
I can't seem to find any information anywhere detailing the behaviour of these modes apart from the mention of the VEBus BMS, shouldn't the setting relate to all BMS's?
