I haven't done it but why can't you use a standard lighting photocell to turn on the inverter? There really is no current involved so the load shouldn't be a problem.
I am assuming that you just want to turn on a light? Just a thought, Bob Ellison From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Solarguy Sent: Thursday, August 02, 2012 10:49 AM To: 'RE-wrenches' Subject: [RE-wrenches] Morningstar MPPT charge controller Wrenches 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.
