New MPPT 150/35 LED lights don't come on and no Bluetooth

I'm trying to get my MPPT 150/35 going for the first time. My PVs and Battery bank are hooked up, but the LED lights don't come on at all, nor can my phone detect the controller. I've tested that I have current coming from the PV panels, and that the batteries are fully charged. I've tested right at the Controller, as well as at points along the chain, and I have current.

Is it possible that controller is not coming on because the batteries are already fully charged? Any other suggestions?

I'm having this exact problem did you ever get it fixed? If so what did you do?

What current are you measuring?

And what voltage?

Left side of controller bottom side where the panels and battery hookup there is a fuse i would check that first.

Please ensure you connect the battery ONLY first.

The MPPT needs to know the System voltage first!
