Frankly, I would not recommend you go with either of these low-budget Chinese units. You'll remember the quality long after the price is forgotten. But, before talking about what unit to buy, you really need to expand on the details of what it is you want to power. I'm guessing that this will be for home power, or perhaps a remote vacation cabin?
If it's for a remote cabin, I'd guess that you'd need about 5kwh per day to live a conservative off-grid lifestyle. This would give you lights, TV/stereo/computer, a refrigerator, and extras like a satellite dish. The two brands I would recommend are Outback's radian, and Schneider's XW. They are both 1'st tier grade products.

You could get by with ~1500W of panels. I recommend getting high-voltage grid-tie panels. Stay away from 12V panels completely. Grid-ties are the most economical choice.
For my own cabin, I have a XW+6848, which is extraordinary robust. I use it to run my 240VAC well pump.
Both of these inverters are designed for split-phase 120/240V AC to be hard wired into a standard North American power panel. They support generator charging, and can be paralleled for increased power demands. They're both designed for high power 48V battery systems.
If however you want something on a somewhat smaller scale, their's Schneider's Conext series, in both 24 and 48V. I have this conext for my workshop.

This one is fueled by eight 240W grid-tie panels. The cabin is fueled by 15 300W grid-ties.
Along with the inverters themselves, you'll also need the charge controllers, wiring, and power centers required for a code-compliant system. Even if you might never have the system inspected, do it to code anyway. Code is there for a reason.
