I'm looking at this inverter https://a.co/d/7o2IrZG with a built in GFCI. Most I've seen don't have one. Is this better than inserting one after the inverter? Why don't they all have one?
Inverter with GFCI

First time seeing an inverter with built in GFCI.
You won't need it if water doesn't come in contact with the electrical devices anyway.
Don't limit your choice to that one, you can install one after the inverter for a few $.

If there are others who may plug directly into the inverter AND use something outside or around water or with damaged wiring or anything else that may cause a short to ground, then the built-in is another level of safety. If a properly installed GFCI trips, is most often because it detected a fault, not because it is faulty.

Some inverters have GFCI on their AC output. You can also add your own externally for AC out loads.
Never put a GFCI up stream on AC input to a hybrid inverter. The EMI (RF interference) filter in hybrid inverter can cause false tripping of upstream GFI breakers. (Can be a problem on RV where camp sites have GFCI breakers on their shore power outlets)

Very true, GFCI's "protecting" another GFCI can cause nuisance tripping. I have had a lot of problems with AFCI's and EMI.
I’ve had a Cotek inverter with one for years and it’s been a pain in the a$$ to be honest.
When it’s hot in my shipping container and the inverter is under a 50% plus load the GFCI trips randomly.
I’ve found that if I put a fan on it the GFCI doesn’t trip despite the small extra load.
Whenever I get a round tuit I plan to swap it out for a regular outlet but that’s been on my todo list for years
.FWIW this is the inverter:
Cotek SP1000-148 1000W, 48V Pure Sine Inverter | DonRowe.com
The Cotek SP1000-148 converts 48 volts DC to 1000 watts of clean, pure sine wave power, and is capable of surging up to 1750 VA for 3 seconds, ensuring even the most demanding motor driven loads, such as fans, pumps, and compressors, are able to be started.
