My inverters are both kind of noisy now. Before I disassemble, I was wondering if there are any easy fixes. I'm thinking the fans might need lubrication since they are several years old. I'm unclear about what would be the best lubricant. I suppose it's possible the fans need to be replaced, but they haven't really been used that much.How do you maintain your inverter(s) or fix fan noise?

First thing you do is go down there and look at them and inspect them. Is it filthy dirty inside the fans location? Clean it up. Are the bearings noisy? Is there slop or play in the fans bearings, up or down, or side to side, due to excessive wear?That's the basics, if worn out, replace.

If constrained, consider improving air flow.

Blow it clean with compressed air if it's dirty. Probably a variable speed temperature controlled fan. Dust inhibits cooling, unit heats up, fan runs faster.Clean it out and the fan will slow.

It should only be used for penetrating and leaving a fine coating of fish oil to prevent oxidation of metal surfaces. That is it, that is what it's designed for, nothing else, to prevent oxidation, not to prevent friction.
