MPPT 75/15 Stays Off

Hi All

Hope i can get some guidance.

I have a SmartSolar 75/15 MPPT connected to two 100W panels in series and a 12V battery.

Currently have a issue where it seems the MPPT does not switch on? All LED's stay off when connected to the battery, battery measures 12.7V. Connecting the panels does not change anything, the panels measure 40.2V.

I checked the fuse as well, all good.

Obviously with the MPPT off bluetooth isn't working either.

Any reccomendations?

Have you checked the fuse?

The MPPT will power up using power from either the panels or the battery, which ever is available, allowing bluetooth connection. It should also flash its Blue light. If it doesn't and the fuse is okay then its probably broken?
