solar disconnect switch
I want to install a switch to disconnect my 155w panel from the controller. The regular battery disconnects are so big. Any harm using a small toggle? Or maybe there are smaller disconnects? I looked ...

I'll have to tell my cousin his fluke meter was wrong and we were not getting 33 volts presented to the MPPT controller, as well as 17 amps @ 14.4 volts to the battery bank. Such a shame when you can't trust measuring devices.
You don't know me Ski Pro 3, but I rarely speculate preferring real life measurements with the best equipment I can borrow or afford.

Panels are often 17 volts. Much higher voltage panels are also available. Mine are wired in series/parallel giving a nominal voltage of 33 on the input side of the controller.
That is the open circuit rating for the panel voltage. No current. Once the circuit is configured, the measured voltage at the solar panel won't be 17 volts, or 33 as the case may be. A switch isn't rated on it's voltage as much as it's rated on it's amperage.
