Are you sure you havent clamped on insulation? Or reversed polarity.

@Mcpsych61 or disconnected the panels ? Bad cable/isolator switched/circuit breaker tripped.

Where are you measuring the panel voltage? Did you try at the cable entry point to the MPPT?

The cable entry to the charger was where I tested the voltage
