" I have 2 lots of solar going in and all is working fine" - Well obviously not.

Is the MPPT showing any voltage on the PV side? A screenshot of the status would help.

How are the panels connected? Have you checked all connections/ isolators/ fuses etc?

I had a similar problem with my MPPT 450/100 RS. I had 3 x 435w on one string and 6 x 435w on the other string. There was not enough voltage on the 3 panel string to start the MPPT. Problem solved by adding a 4th panel.

Just to add.


The start up voltage on a tracker is 120V.Once started it will track down to 80V before switching off.
