Dont forget to clean your filters!

Post by grenadapalace » Tue Mar 10, 2020 8:08 am

A timely reminder...

This caught me out today, (a small power outage due to Over Temp). Make sure to keep your filters clean (inverters that use them especially). I have four VFXR3048E and always clean them all in one go (though the main inverter in a stack is always much dustier though).

I did the clean 1 year ago but you will be amazed at how much dust they collect. I have changed my clean schedule to once very six months...

Excellent reminder! Some people cycle their main inverter with the others, too, like cycling tires on a car :grin:

I took the covers off my inverter air intakes so i could see firsthand how dirty the filters are. Had a high temperature problem awhile back and discovered a very dirty filter.

Mike, is it necessary to remove the filter cover plate? I've just been running a shop vac with a brush attachment over the filter openings. Cleans them of dust visibly but is that good enough? The manual says nothing about filter cleaning.

H - Not sure how you would access the filter on your 4048, but on my GVFX's I had to remove the cover. Heres a photo of the air intake filter I took a couple years ago after I got the high temp alarm. I have never replaced the covers so I'll notice when the filter gets dirty, but the downside is the battery connections to my inverters are a bit more exposed.

I have the vented inverters, and the black filter, just under the top cover was really dusty. I took my top plates off (4 cross head screws) removed the filter, carefully vacuumed the metal perforated mask the filter sits on, then washed the filters in some mild soap. Make sure they are very dry before refitting as the inverter sucks air through the filter and will suck water in if they are not totally dry... In a stack, your main inverter filter will take the biggest hit with dirt. By the way, after cleaning, mine have been perfectly happy. One other tip, on the vented inverters , there are small perforations to let out the warm air on the top and bottom (when mounted horizontal) sides. Again, I carefully vacuumed these...

Mike, the manual is silent on that too. Here's a pic of the filtered air intakes on the bottom of the GS4048.

I vacuumed off the openings so they look pretty clean now. Had a lot of construction dust after installation. But when I took a closer look today to determine if there was a way to remove the filters for better cleaning I saw no obvious access. There's some screws missing, as you can see. Probably not critical since everything is working fine. I assumed the two large screws at lower left and lower right should do it but no joy. I'm guessing I would have to remove the whole front panel of the inverter to get complete access to the filters (should it ever be necessary). But like I said, they're pretty clean as is.

FYI, the "filters" are nothing more than wire screens with openings maybe 1 square mm. Unless there's some real filters inside the case. I might need to email OB to get an answer on this. My inverter happens lie in the circulation path for our HVAC and we have a lot of dust here in the desert. Not to mention a German Shepherd. :)

Any insights? Thanks.
