hey guys,
I purchased a PowerJack 6000W LF SP PSW 24V inverter about 6 months ago. I picked up a brand new unit on Amazon for $325 & free 2day shipping prime. For the price I couldn't pass it up.
When I first received it, I had opened it up to check / verify all connections etc... At that time I didn't know to check if I had one of the units that only had a filter CAP on 1 leg or if it did indeed have a filter CAP on L1 & L2.
I've only used the inverter twice since I received it for maybe a hour each time. But I can say that the fan is quite strong in my unit and does come on pretty early unlike some of the units out there. So I'm hoping I got lucky and got a unit that was built before PowerJack started skimping out on parts etc... I'll post some images of my unit below if it might help identify when it was made or etc...
So basically my main question is, when I open up my inverter again to check if both L1 & L2 have filter CAPS and I find that it does or doesn't, what type and specs of capacitor should I install to get the best filtering? and lets say it does have CAPS on both legs, is it worth upgrading the filter caps or add more in parallel?
Thanks Guys

Expect no more than 2-3kw continuous max out of the inverter. That's just how it works 😉.

Pretty sure it's their latest model (likely will have a 10.3C or 11.0 control board in it). Older inverters used to have the AC output terminals at an angle--this one has them mounted straight up/down. Older inverters also had a fan over the transformer--this one has the "indication" of a fan on the label.
At that time I didn't know to check if I had one of the units that only had a filter CAP on 1 leg or if it did indeed have a filter CAP on L1 & L2.
Hard to say. If a wire goes directly from the transformer to the power output terminal, that'll tell you pretty quick that it's not filtered.
Filter caps are 4.7uF ("476") and rated at least at 250vDC (most commonly 400vDC). For as small as the transformer is (likely an ASL1 / ASL2), one 4.7uF cap per phase will be beyond adequate.
