New inverter. Haven't had it work right yet. Using it for RV refrigerator when on the road. 3.5A, 120v. Actual voltage is 110v. It's right at the limit of it's capacity. Batteries charged to 12.85v.
You're running more than the specified power. The refrigerator is an inductive load, which means the power factor Pf will be less than one. Consequently, the power draw from the inverter is Volts x Amps / Pf. Also, if the inverter voltage is less tan 120V, the refrigerator's compressor and fan motors will draw more current than the nominal rating. How much more depends on the motor design. The harmonics from the inverter (it has anon-sinusoidal input) may increase energy loss in the motors, especially if there is a fan with a shaded pole motor (common in refrigerators). The bottom line is that you are probably drawing at least 420 Watts from an inverter rated for 410 Watts. It's very close to shutting down on you, and may cause premature failure in the refrigerator.
I recommend getting an inverter with at least 450 Watt capacity, preferably with a true sinusoidal output, or harmonic content less than 5% under full load..
Testimonial: "This isn't a household fridge. It's an RV fridge with no compressor. It only has a small heater to heat the coolant. There is no surge. I agree, though, that it's running on the edge of the inverter capacity and that's probably the problem. thx"
SOURCE: red light on surge protector
Yes i think it is, I think the red light just means that it is surge protected, My ones red light is on constantly to.
SOURCE: batteries don't charge
Dust getting in the charger is a problem, Try blowing it out with a moisture-free dust remover, found at most any store. Green flashing means improper power, due to dust or power from the outlet, try a differant wall outlet. Red flashing means the charger or battery is to hot and must cool down before it will charge. The charger will not charge a battery if the lights are flashing. Solid Red light means it is charging and solid green light means it is charged. Plug the charger in first before putting the battery on the charger. If the charger has been droped or hit the floor the coil inside could have broke loose and dammaged the charger requiring it to be replaced.
SOURCE: Unit cools fine on 120V, selecting GAS CHECK light on.
Do you hear a clicking sound If not. there is a black box inside the out side door. Check the fuses in it.
