Using battery setups are primarily for use where there can simply be no AC delivery, desire for independence / emergency use - but it is far from cost-saving.
A big mistake is that once a person gets a system up and running, that is based on their *current* power-budget and never exceeding it. That might change if their needs go higher based on the excitement of success!
Also never figured in is the cost of battery-replacements down the road. As a lifestyle, it is not just a one-time occurrence living from batteries - unless one's plan is to dumpster-dive for battery trash.
