I have a small PV system with two 100w panels, two golf cart batteries in series, and a Voyager CC with optional temperature sensor. Everything works great, except I can't get the temperature sensor to display on the CC. I can cycle through the data: voltage, amps, and amp-hours, but no temperature shows. I have reconnected the sensor several times. Am I doing something wrong? Any suggestions appreciated.

Hello, When connecting the sensor the temperature display should be automatic on the charge controller screen. If you have already verified making sure the connection was inserted to the fullest extent and a tight connection, then perhaps the sensor might not be functioning correctly. If you have a multi meter, check for continuity between the sensor end terminal (one) and the terminating lug. If no continuity can be measured, then the temperature sensor might be defective. Hoping for the best, -Renogy Team

Thanks for the quick response. I will check for continuity. Also, should the sensor be connected to one of the battery terminals? The manual doesn't say anything about positioning the sensor.

The temperature sensor side with the pins go to the controller and both need to be connected to the port on the controller. It is not voltage sensitive so just as long as they are tightly secured. The lug side can be connected directly to the battery post, placed top of the battery, or placed on the side of the battery. The purpose is to get the sensor near the battery for accurate temperature compensation. All the best! -Renogy Team

Your Customer Service folks sent me a new temperature sensor to replace the bad one - thanks! Now I measure about 9k ohms across the connection pins. I also measure 9k ohms from the black pin to the lug end and 22 ohms from the red pin to the lug. I want to make sure I hook this up right, so does it matter which battery terminal I connect the lug to?

Yep it sure does matter, it doesn't hook up to a battery terminal at all it goes on the side of the battery with tape... It's a temp sensor not a voltage sensor...
That could be why your last one went bad.....
Which end is the lug on?? If it's on the CC end it's a ground...
Can you post a pic of what your talking about??

The Voyager CC Temp sensor has a lug connection whereas the Renogy Adventurer, Renogy Wanderer, Renogy 20A Commander Controller, Renogy 40A Commander Controller, and Viewstar Charge Controllers use the pin sensor type. www.renogy.com/solar-charge-controller-temperature-sensor/www.renogy.com/voyager-charge-controller-temperature-sensor/So daysailor, you might have the wrong sensor, call Renogy.

Thanks for posting that.... If the lug is the sensor no wonder it's confusing...

The temperature sensor is supposed to be within proximity of the battery and not connected to the actual lug. -Renogy Team

but it wouldn't hurt to connect to a battery terminal.
tape to the center of thermal mass (on the side of a single battery), that's below the liquid level!

but it wouldn't hurt to connect to a battery terminal. So it would't short out something if it's connected to the positive side? Or the neg for that matter..

Who ever decided it was a good idea to put that lug on the end of a temp sensor should be fired... that's a problem looking for a place to happen...

Thanks for all the replies. I have attached a photo of the sensor I received for the Voyager CC. It has a lug that is electrically connected to the temperature sensor. I measure about 2 ohms from the lug to one of the connections. I plan to tape the sensor to the battery since it's not clear what might happen if I connect it to one of the battery lugs. I suggest Renogy update their Voyager manual to clearly show how this should be installed.
