I have a 24v battery system wired into an Orion 24v->12v in order to run the 12v side of my camper. So far I only have a string of LED puck lights and an Espar diesel heater running off the Orion.
I noticed that as the Espar cycles off, I can hear the Orion making a rapid clicking sound and it causes the lights in the cabin to pulsate at the same frequency. I don't measure any voltage drop at the Orion's connection to my fuse panel during that, and otherwise any other 12v device doesn't seem to care about the pulses. This also doesn't happen as the Espar cycles on (when it's at it's peak power usage).
Any idea what that noise/flickering is about? Problem with my load, or problem with the Orion?
Thanks for any insight!
