VRM ext. control

hey,

two systems both BMS controlled with DVCC.

no. 1 has a 123smart BMS

no. 2 Pylontech


all MPPTs under external control (Connect App)


but on VRM No. 2 ext. control is missing.

i´m asking because i have trouble with system no 2, MPPTs stopp charging every day for no reason at noon.

My MPPTs are on External Control, because I use ESS. If I open the MPPTs in VictronConnect, they show "External Control".


But in VRM dashboard, "External Control" tag is not shown in my system either.


So check how they appear in VictronConnect.

as i mention in my post,

all MPPTs under external control via checking the connect app.

both system w/o ESS.

the difference are the BMS, Venus device and the MPPTs.

Pylontech with 150/70 CAN

123BMS with 100/20


the 123BMS works perfect ( raspberry pi)

the MPPTs with Pylontech w/o the "ext. control" in VRM stopp charging for no reason (cerbo gx).
