[RE-wrenches] Morningstar MPPT charge controller

[Larry Crutcher, Starlight Solar Power Systems]

I built a billboard lighting system with the Suresine inverter and LED flood lights. It is the only inverter that works in the extreme summer temperatures in Yuma, AZ. 

The PV controller is the Blue Sky Energy SB2512iX. It has an amazing programable lighting controller built in. You will need to use the IPN-Pro remote to set up the program. The Aux. output drives a 30A SPST automotive type relay for switching the 12 volt line to the inverter. It has been working well for over two years.

The Morningstar Sure Sine inverter and MPPT charge controller sound like a good match considering the reliability of their products. But when I tried to use the CCs ability to act as a timer to turn on/off the Sure Sine via its remote on –off input terminals I found that the two are not compatible. A call to tech support and I find that I must use a third-party relay to activate the 1P-1T switch on the Sure Sine.
I’m sure other Wrenches have come across this combination before for a 12V lighting system so I’m wondering what specific brand or technology of relay works reliably in a hot location. I prefer to have a DIN mounted relay but will consider something else.
Thanks in advance
