Other than the cost, would someone kindly discuss the relative pro, cons, and features of the subject two senor suites? Thank you.

I have the same question. I just sent this to my irrigation installer and I'll let you know what he says. The Solar Sync certainly seems much smaller and easier to hide/mount.

I'd love to hear what someone from Hunter says. The preliminary research I've done indicates that the Solar Sync sensor suite in simpler than the ET System. Also, the SS adjusts the watering time by changing the seasonal adjustment. This then changes the watering for all zones by the same percentage. There is only one variable that needs to be set, that is "Region" or ET rate.

The ET sensor suite seems to be very comprehensive, including an optional aenometer. The system appears to be able to control and adjust each zone independently. Setup can be very involved as the system considers many variable for each zone (soil and vegetation type, ground slope, sun exposure, sprinkler type, etc).

I'm wondering if the SS might be sufficient for most residential applications?

I am a Product Marketing Manager at Hunter. New to Irrigation's last post is a very accurate description of the differences between Solar Sync and ET System. Toby's comment on the relative size of the Solar Sync was also one of the important marketing targets during the development of this product. A question was raised as to the Solar Sync's sufficiency for residential use - it was designed to be used primarily in residential and light commercial applications. It is very easy to set up and allows the irrigaiton installation professional to set up the run times as they normally do then the Solar Sync simply adjusts the run times if the weather changes. It does this every day! It's like having an irrigation professional with weather equipment adjusting your run times every day to ensure you don't use too much (or too little) water. Grass stays green and you avoid overwatering at the same time!

I have installed multiple ET System and Solar Sync sensor suites. I will tell you that the ET System has technical advantages over the solar sync yet both require the professional to monitor the site performance and make adjustments over time in order to maximize the return in water savings. The distinct advantage the solar sync has over the ET Sensor is the obtrusive size and location requirements of the ET Sensor. It must be within 100 feet of the module and the specifications require it to be in the lawn in full view of the residents. I have decorated the mounting post with lattice and hidden it pretty well but when selling the suites, my customers prefer the unobtrusive mounting location of the solar sync.

I wouldn't trust any Hunter controller any further than I can throw it. There are plenty of better weather based solutions on the market currently!

rude and unproductive

While we have not utilized the ETT system, we have installed several Solar Sync modules. After one season of use they have done well in modulating water usage in residential applications. Simple to install, unobtrusive and relatively simple for the residential customer to use. At this point in time, we are going to offer them to all of our residential customers. Good day!

First of all, congratulations to the solar sync. We tried to push the ET-System but it was to much for our customers -> they preferred having the control over the controller? Solar Sync is the best answer for those type of clients!
What happen's when a client use pro-c with a solar sync and uses the sensor for stations 1&2 and station 3 should run without sensor? does the solar sync increase/decraese the station running time at station 3 too?
