I'm running the beta software to test Victron Connect and upgraded my MPPT to 1.44 and my BMV is at 4.01 (it's not prompting for a 4.03 update). Both are connected to a venus device with a VE.Direct to USB adapter as my venus is a raspberry pi. Since I upgraded, the MPPT is in fault. I do not have an ESS nor do I have an intelligent battery. Once I leave the ve.smart network, the mppt starts charging again in bulk. As soon as I rejoin the network, the mppt goes back into fault. I use the VE.Smart for temp sharing from the BMV to start charging below freezing. It's going to start getting chilly so I figured I'd post here. I also submitted beta feedback.
I should have paid more attention after loading the firmware as I didn't notice at all. I'm glad I installed an LTE modem in my van as I got the VRM alert about low SOC.
