Why won't my inverter drive a domestic fan?
I thought that I was reasonably up on electrics and know for example that you can have trouble using inductive loads on an inverter but I can't get a 300 watt PSW inverter to drive a 35 watt domestic cooling fan. Within seconds of switching it on the inverter alarm will sound and the fan stops.
I accept that some motors use up to 5 times their rated power to start but I would have thought that 300 watts would have started a 35 watt rated fan.
If I'm never going to do it without up-rating the inverter, which I normally only use for laptop and toothbrush etc., what other suggestions for cooling in the motorhome are there. We have a "Transcool" 12 volt "wet cooler" but it's pretty noisy. It was OK when we had dogs as they had no option about the noise and in any case they were pretty deaf!! Are there good and reasonably inexpensive 12V fans? Small dashboard ones don't appear that sensible.
Thanks in anticipation.
