Looking for a 12V DC under voltage relay
I just installed a new Norcold refrigerator on my Gemini - powered by 195 watts of solar, a Blue Sky 200E (see other post for problems), and 200 Ah of AGM batteries.
After several unattended days of clowds, the voltage in the battery bank dropped below that required to run the Norcold. I expected the unit to turn off - but it didn't - the draw continued with no cold produced until the battery went to zero volts.
I'm looking for an undervoltage protection relay that will pull in at about 13 volts and drop out at 11.85.
Any idea where I can find one? Thanks /Stuy
