It depends on where you live, not everything is easily available worldwide.
Any name branded unit will probably do the job, watch for complete technical specifications and documentation as all proper manufacturers will provide these for the customer to read. If it seems incomplete, hard to find or even missing then go to the next one.
And also it might be worth checking local stores for their own brands, they will probably sell you some OEM components made for them to be sold under their own brand. It's usually decent stuff as they don't want to sell you crap under their own name.
And last but not least, number one rule that always applies, if it's too good to be true then it's likely not true. There is no decent 24V 2kW pure sine wave inverter for 50 bucks or something like that. Expect to get what you pay for.
Something that is sold under a known reputable companies name and not under any fake marketing brands solely used for advertising stuff. Victron, for example. It varies from country to country though, or nowadays more like from continent to continent. If you are in the US you will probably have many name brands available that I've never heard of. If you don't know any either then just have a look what's being offered at Amazon or any specialized dealer.
Brand Name is the name that is used to sell the product. Nike, Microsoft, Apple, Amazon, Google, Samsung, etc, etc, etc. Those are brand names. It doesn't describe what's "inside" the package. It's the designation of what is being sold.
