I replaced my existing PWM controller, which works fine, with a Victron MPPT 75 I 10 in order to get better yield in winter.
After installation Green and Yellow LEDs BOTH blink permanently
Checked battery and panel voltages - within range.
Tried with different battery but problem persists.
Tried different jumper settings (and none).
Reverted to PWM all OK.
It looks as though I must be missing something basic (like a reset button?) with the Victron?

Is it a BlueSolar or SmartSolar?
Check the fuse at the bottom of the MPPT.
I’m a bit confused, doesn’t both lights flashing mean that it is either in bulk charge or absorption charge?
The battery life flashing just indicates that the load output will be turned on or off at more conservative settings to ensure that the battery receives a full charge.
If it’s a smartsolar would you be able to get a screenshot from VictronConnect of what is happening?
If BlueSolar can you let us know what the voltages are and if there is any current flowing?
