Smaller battery storage devices with an inverter were called 'solar generators' because they generate power from the sun via solar panels and output it from an inverter. Today's ICE generators use inverters as well. It's the fact that they make power that they get called a generator, doesn't matter if it's from gas, propane, etc... using an ICE motor, or the sun. Just replace the ICE motor with a solar panel and charge controller.
As these things got bigger and bigger, they became less of a solar generator and more of a power station, as Gurps noted.
Not a bad price. The new Ecoflow Pro 3 was on my short list, and I held off buying until it came out, and I could get the actual specs and see reviews. Still went with the Anker for a few reasons: it has a larger inverter (6000w v 4000w), better surge capability, better battery expansion. I already had 2 Anker portable solar panels @ 400w. The Ecoflow had a number of nice features, but none that I would take advantage of, like backward compatibility with older series batteries, flexibility in configurations, I also kept seeing odd problems described and trouble with support, but virtually none with Anker. The only thing I wish the Anker had was pass-through charging, the ability to charge via 120/240vac while still providing 240vac.
Here's a side-by-side comparison. Both good units, the Anker fit my needs better.
