Is it better to get a charge controller and inverter in one? Can you also daisy chain a bunch of these batteries to extend the capacity?

And I just bought the 150ah battery charger combo.

Solar is becoming like computers in the 1990s, with things become super cheap every 6 months.

AIO units are getting cheaper and are super simple to DYI a portable solar generator/backup battery system

What to buy really depends on what your trying to accomplish.
12v inverters have their placed but if you need something 3500w+ you should really look into a 48v system. If you go 48v, 48v batteries are better than putting 4x 12v in series.

Go to YouTube and search for "DIY Solar Power with Will Prowse" He has a lot of videos that go into details.

Will Prowse is the man. Great for learning about solar and lifepo batteries.
