I have a rev3 150/45
For some reason, it keeps changing from it's setting of "user defined" for lifepo4 to rotary switch.
You can set it back, but eventually if you go look on victron connect, the settings have reverted to rotary switch again.
Older rev mppt's are behaving fine.
Hi @nickdb,
which firmware version are you using? Have you tried re-flashing the firmware?
Try turning the rotary switch to a different position and then put your user defined settings back in. I suspect that the rotary switch contact is "bouncing" and causing the settings change.
