Can a negative MPPT disconnect a solar panel?

OPINION: Having an additional disconnect on the negative won't hurt anything, but it does nothing additional to actually disconnect the solar panels from the system. No power will pass from the MPPT to the rest of the trailer's circuits once the + is disconnected between the panels and the controller. Sample AMSolar diagram

What is a safety disconnect in a solar PV system?

A solar PV system typically has two safety disconnects. The first is the PV disconnect (or Array DC Disconnect). The PV disconnect allows the DC current between the modules (source) to be interrupted before reaching the inverter. The second disconnect is the AC Disconnect. The AC Disconnect is used to separate the inverter from the electrical grid.

How to disconnect a solar panel system after turning off inverter?

After turning off both the inverter and the solar array, it’s time to disconnect the solar panel system. This procedure can be achieved by disconnecting the solar panel cables from the array. An appropriate sequence is vital to avoid damage to the solar panels or any accidental electric shock. Follow these steps:

What is the second disconnect in a solar PV system?

The second disconnect is the AC Disconnect. The AC Disconnect is used to separate the inverter from the electrical grid. In a solar PV system the AC Disconnect is usually mounted to the wall between the inverter and utility meter. The AC disconnect may be a breaker on a service panel or it may be a stand-alone switch.
