Morningstar Remote Temperature Sensor (RTS) - Connects Battery to Charge Controller to Provide Accurate Battery Temperature Info When Battery & Controller Temperatures are Likely to Differ by >5C

NOt much to say. The product is good and shipping is good.

Have not really connected this yet, but it looks like it is good, I like the long cord that is on it.

It is what it is, a remote temperature sensor. You can attach it to one of the bolts of the battery or tape it to the side, etc. Plenty of wire length — I actually cut it in half and used the other half as the voltage sense wire which begs the question, why didn't morningstar use 4 wires for this? To combine the voltage and temperature sensors into one shielded cable? That and the price are my only complaints. At the price it should have been 4 wires in one cable to be used as voltage and temperature. Nonetheless, you really do need temperature correction.

Works. Shows difference 'tween inside on the meter and outside where the batts are at. Necessary in Phx, where it sits in the summer, to keep charging rates in check to prevent over heating.

This remote battery sensor is a must have, the charger was using ambient temperature for the battery, the ambient goes up with the heat-sink temperature. When the perceived temperature goes up, the charging voltage goes down, and does not charge correctly. With the remote battery temperature monitor, the charger knows the correct battery temperature, and charges to the proper voltage, I really do not understand why this is not a standard piece of equipment with the charger.

Worked well. They need to offer options without so much cable. I threw 90% of the cable away.

I haven't installed this particular sensor yet, but I have others. Temperature compensation is the only way to go with solar battery charging if you want the controller to apply the correct voltages. This sensor on a Tristar controller will ensure that your batteries get as fully charged as they can be, and as a result make them last longer, and help you have more power to play with.

Funciona muy bien

This was a replacement for a damaged one and it works as expected.
