Hi all;

I need to replace the cooling fans in a Trace SW4548E unit. I'm aware it's a bit of a full dismantle to do it. Has anybody tackled this job before?

Cheers

From my knowledge of the forum i dont recall it being a past topic, although it should be a rather easy job and only require removing the cover and a small dismantle, nothing major that i would expect.

On average the fan is screwed to the outer casing (not a major component) and normally with a 2 wire plug in to the circuit board, but i dont know the Trace SW4548E, and never looked inside one, but fans are fans, regardless if its an inverter or a computer or whatever, most use a somewhat common DC fan of nominal sizes, and its likely a fan from an old computer power supply would replace what you have.

The important factor to know is what voltage is printed on the back of the original fan, i would guess 12v with 2 wires, red, and black, but it could be 24v or perhaps any voltage, but on average most manufactures use a common off the shelf fan (why redesign the wheel or fan, as there is no money in that component).

Pop the cover off and take some photos of the fan location and where the wires connect to the board, then we can offer more help.

Also add a actual location to your profile, as there maybe someone in your area that is happy to assist you with changing the fan.

On the matter of cooling fans, the manufacturer does not know how the unit is to be mounted so its important the fan blows the air in the right direction.

For example, one of my inverters had the van on the end that was to be on the bottom when the unit was hung vertically onto a wall. Problem was, the fan sucked the air out of the unit. No good if its forcing the cooling air in the wrong direction.
Fortunately, most of these fans are easily reversed mounted, I just turned it around.

For a fan on the top of a vertically mounted unit the cooling air should be sucked out after having entered below at some slots in the housing.
