Is it polarity protected in case the leads from the solar panel are accidentally switched?

I don't believe that it is, however they are very clearl marked pos. and neg.

I don't recall, but this is a well-made unit. I replaced another popular one with this one.

According to the manual, it is protected whether the battery or the solar panel is connected wrong.

The switches are not polarized. Think of them as a piece of wire that is continuous when the button is pressed. You can connect them with either terminal to either pole of your voltage source.

Just wire one end to your power supply, being careful to get the polarity correct. You should protect the exposed wires on the other end.. I just covered each lead with a small piece of heat shrink tubing.

As shown in the photo, the yellow dial on the Left is the polarity selector. You can select which polarity you want.

If you have a voltmeter or multimeter, you can just plug it in and determine the polarity of the leads that way.

Polarity does matter, but the wire colors have changed from batch to batch (I've ordered several pairs over the past few years), making trial and error the only way to tell which is positive and which is negative. There is no harm hooking it up backwards, it just won't work until hooked up correctly. I have only had one break a wire internally (after crashing the dirtbike and breaking the mounting screw, it dangled by the wire for several miles before we noticed it.) Once home, just took it apart and re-soldered the wire to the board, replaced the broken screw, and back in business again.

Don't know what kind of system you have but we have ours on a RV and one wire came off and it cooked the two fuses on the inverter, cooked the inverter, and we had reverse polarity. So for the price of a 5.00 fuse that I could of had at our leads from the batteries it would of cured the big expense and headaches.

There is no polarity since the meter is set to measure Ac volts and Ac amps the green wires just go to the green terminals

the controller prevents reverse polarity. remove the diode it does not do anything

I agree with T. Thomas, sounds like reversed polarity - it's easy to do as the documentation is not very clear on the wiring.

yes however the wire polarity may be switched so test before putting everything back together.

you need to add one on the positive lead. the diodes are polar so make sure the white line is on the load side.

No, no polarity detector. You have to change the connection to measure charge or discharge currents.

Attach a multi-meter set to measure dc volts, to both wires, just like testing a battery. If the movement is off the grid, then the wires are reversed. If the meter tests correctly, then the polarity is correct.

yes you really should ground the system otherwise you will have a floating neutral situation which is not very good for most power sensitive appliances etc.

The switch is designed to reverse polarity for direct current....such as a twelve volt system....what are you working on?

Polarity should not be an issue. Also these are probably a little large for an instrument cluster. Check for cross reference guide for what you have now.
