Hi Folks. I have a 48 volt off-grid system, with an inverter. Some loads I run directly off the battery bank, such as the fridge. I would like to try to run a security system comprised of components that will run 48 volts. The issue is that the battery voltage varies between 49 to 59 volts. I wonder if anyone has experience with a small regulator circuit to control the battery bank voltage to get a regulated 48 volt supply?
