I'm sure he means you can buy multiple 100ah LiFEPO4 batteries and connect them to the Max's two solar ports instead. I bought a 52v 30ah (1560wh) one for $330 and with both ports will put about 800watts into the max.

Bad price even on a $/Wh metric ($0.371/Wh) alone. Factor into the proprietary lock-in (EF has even moved to prevent this from being used with other power stations like the Delta Pro) and the older design, it is definitely not worth it. Plus the head unit (Delta 2 Max) has horrendous self-consumption and poor AC efficiency.

At $500, maybe worth buying.

It's compatible with the delta 3 plus as well. You're paying for convenience. It's like a crappy iphone. Pay more, get less, but it works even if you don't know what you're doing. And it looks fancy (for being just a really big car battery)

Do you have a link regarding the setup you're referring to?
