I've looked into different float switches and need some help figuring out which model to use. I know how the wiring schematic works, for the most part, but I have a few questions. I think I'm going to use a "tilt float switch" model. These have different ratings associated with them.
1. What is the VA rating? Is this the same as the contact rating? How does it apply to a solar-powered well with variable current levels? Do I stick an ammeter on there in the hottest/brightest part of the day to test the highest reading and buy one with a rating that can handle it?
2. They also have a Max PSI rating, does this only apply to pressurized tanks? My tank is a holding tank above ground and it is not pressurized, so do I not need to worry about this?
I don't think these tilt float switches require their own power circuit, but if I'm wrong please advise. I have been told they are just "contacts" - although I'm not an electrician/plumber so I'm not very sure what that means. Does the control module/inverter run it's power through the float switch circuit and the way the float switch works is it breaks the circuit when it's full (i.e. normally open)?
More info: control module/inverter is a LORENTZ PS2000
