12V and 120V System Q&A

Inverter question

Unread postby mikhen on Sat Aug 07, 2010 7:58 am

Our inverter fan cycles on and off. It doesn't run, then I guess when there is battery drain, it turns on. It stays on till the fan gets up to speed, then shuts off. It does this 3 or 4 times a few seconds apart. Then repeats when there is battery drain. Does the cycling sound normal?

What brand of inverter do you have? My stock one does that from Time to time, if the batteries are low on charge than the fan will run all the time while charging.
Once they are charged it will cycle the fan on and off depending not the load.

Do you happen to know the voltage of the batteries when the fans cycle on??

Is this happening when there is a load on the inverter or does it happen all of the time? Inverters are very sensitive to battery voltage which will drop considerably under a heavy load such as a coffee maker or hair dryer. A high wattage load will drop the battery voltage which will lead to increased current draw leading to heat issues. Is the fan just trying to keep up with the task of keeping the inverter cool? Remember that watts = volts x amps and wattage is usually consistent meaning that when battery voltage falls, the inverter will draw more current to compensate. Current = heat.
There is no such thing as a bad day camping.
