Additional battery or Solar Generator?

Hi All, very torn. Looking at the Ecoflow Delta 2 and the Bluetti, 200 max. If price were no object, I would get the 200 max and have a stand alone backup to my existing system...but money is an object.

Question. Thinking about getting another SOK 100 battery. Already have an inverter and charge controller, or I can add another battery to my existing system.

The why. The reasoning is portability vs cost. Obviously, the cost of a new battery at $570 is cheaper than the Ecoflow Delta2 at $1000. Same output. Just easier to move.

Any thoughts would be appreciated. Thanks

Only you can decide if portability trumps cost. I personally have never been a fan of AIO devices. Especially those that are proprietary like solar generators.
