Inverter power I use 4 gauge wires about three feet from the batteries to the inverter. I only use one item at a time when using the inverter, usually the TV or DVD and have never had a problem. All connections are tight and all battery cells check out good. The red lights are for the inverter overload. I am guessing this 400 watt inverter is just too small for the start-up as you said. I usually boondock and never use this fridge that is in my outdoor kitchen area but I have a month long trip planned where I stay several days in each campsite that has electric so I thought I would use the fridge and when travelling I would run it off the inverter. Each trip is 4 to 6 hrs apart. Rooftop solar would keep it charged while driving and keep fridge cold. I guess it is a bad idea or get a bigger inverter.
