Michelle: Tks for that info. Do you have any ideas about the inverter? DAN Stansel
Dan, the fan you hear may be the cooling fan for the charger portion of the inverter/charger. I know my Prosine 3000 fan comes on frequently even when the inverter is on standby.
Dan, is it possibly just the little squirrel cage blower in that bay running? I think there's one mounted on the ceiling of the bay to keep it cooler and it's likely thermostatically operated so possibly fighting the "delightful" temperatures we're having here in Texas. You might try flipping the 12V disconnect by the entry to see if that shuts it off (just be sure the inverter is off, too, since it generates some heat).

Michelle: No the fan is off the noise is from the inverter so it must still be trying to do something. How can I turn it completely off? DAN Stansel
Isn't the Prosine 2000 both the converter/charger for the house batteries and an inverter? If so you don't want to turn off the converter/charger portion do you?
Kent OK so if it running it is charging. Will it cut off when charging is completed? I just don't like it running all the time. DAN Stansel
My Prosine fan is on a thermostat. It only runs when the charger temp is high enough to warrant the cooling fan coming on. In this weather Dan, that is almost all of the time except at night.
Kent What is on is coming from the Prosine itself the fan off DAN
... Will it cut off when charging is completed? ...

As long as the converter (charger) is on, it will maintain a "float charge" on the batteries. That is good if the settings are appropriate for your batteries. The fan is likely to cycle or stay on, depending on ambient temperatures in the bay where the inverter/converter (charger) resides, and the condition of the batteries.
On our 1997 U295, I leave the coach plugged in with the boost switch on to charge all the AGM batteries. The fan on the Heart 25 runs frequently, but not all the time.
well so far I am happy with my solar panels looking after the charging part (and providing 120v when needed) and do not have to think about inverter/charger fans or !. I have done what many of you have attended to and put the trickle charge unit on the coach and after a month away in Europe I came back and instead of having the usual slowish cranking at first, the engine fired up like it was started by a new battery (which it is ).
I have ordered a POWER PULSE unit ($50) to put on the house batteries after a discussion with the Tech at Batterystuff in Oregon and he reckons it will add years to them (batteries) as it will look after any sulphation problems that the Prosine and solar controller do not. Hope it works that way !!
I am adding a couple more 150w panels to the roof soon, now the sat' and winguard antenna have now gone, so will not be as dependant on shore power or gen-set as would otherwise be.
I also have a Prosine Inverter/Charger that makes fan noise. I think one of the three cooling fans inside has a bushing that needs oil or needs to be replaced. Have any of you guys replaced the fans or had the unit apart? Do you know if Xantrex sales fans. Thank You for any ideas. Karl
We have a Xantrex 3.0 charger/inverter that has a fan (or fans) that come on about every 5 minutes or so and run for about a minute. Times vary with the outside temp. I was really paranoid about the fan noise last year (our first year with the coach) and actually turned off the charger at night and ran everything off the batteries. I was afraid something was going out since the fan seemed so noisy. The Xantrex 3.0 is no longer made and I can only imagine how much a replacement would cost. While we were at FOT in February I had an experienced tech listen to the fan and he thought it sounded 100% normal. So I have just let it run this year. Funny.... I don't "hear" it any more!
Last year (when I was worried about it) I called Xantrex. The person I talked to said they do not service these units. I don't think they sell parts either, but I'm not sure of that.
