MPPT turning off intermittently

1000017895.jpgI have a 100/50 and 150/60 smart solar controllers along with a Cerbo. I have had intermittent problems where the 100/50 will go to a bulk state in the morning and then immediately turn off. The only way to get it going again is turning it on and off via the connect app. The 150/60 works fine. Both connected with VE direct. PV voltage is 60 volts on a 12 volt system. Not sure why it turns off. As a second question I have not figured out how to reset the controller using VRM remote control. Thanks1000017891.jpg

Their outputs can interfere with each other if you're starting at a very high state of charge.


Are they in a VE.Smart network with each other?


I'm not aware of a way to reset it in VRM; however, you can use VictronConnect to connect to the MPPTs through your VRM remotely and cycle the charger OFF/ON in Battery settings.

Thanks for the reply. I had originally set up the system with just the mppt's and smart shunt so had them networked. After installing the cerbo and ve direct cables I failed to turn off the networking. Hoping that takes care of the issue.

I still haven't figured out how to access the enable/disable on the mppt through vrm to let me reset the mppt. I can see all info and status but not any control function like the connect app has.

Thanks again as I now can remotely turn off the mppt and then re enable. That takes care of the controller being stuck in the off state. I believe tuning off all the smart networking was the original problem with the mppt getting turned off.
