@webers3 That phantom 11.3v was probably due to the tiny current which powers the “red fuse is blown” LED in the WFCO. The LED is usually shorted out by the fuse, but when that’s blown a trickle curr… (View Post)
A "monitor" which does not include a current-measuring shunt is rarely reliable. Merely measuring the voltage is not enough. You mention have a Victron (which is not a shunt) - Is that a s… (View Post)
We use around 500wh/day with our 12v fridge and miscellaneous lights. Our 200Ah of batteries last 4 days without any solar - i.e., a shaded campsite. You might expect about half of the rated generat… (View Post)
That’s a too-dang-high voltage drop for the situation. Guessing that the cooler draws 5 amps gives the wire a connector resistance as 2V/5A or 0.4 ohms. Estimating 25’ of wire (12-ish there and back… (View Post)
