[RE-wrenches] Morningstar MPPT charge controller

[Solarguy]

The Solar Boost 2512 has one big advantage in that the lighting timer
control is built in. Morningstar Sunsaver MPPT requires a separate relay
between the inverter & controller. However the Sunsaver has almost twice the
PV voltage input limit of the Solar boost. I'm relieved to hear the Sure
Sine inverters high temp performance is reliable. 

And though no one asked, I found a battery box at
http://www.ddbunlimited.com/more/outdoor-rackmount.html#pad. They are pricey
but top of the line enclosures.

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
