Absolutely. They do tend to be quite a bit more expensive per watt though. From my research you can get cheap panels and just plug them into a LiPo4 battery or even lead acid batteries as well. It’s just that batteries (even though they’ve gotten a lot cheaper) are still expensive enough to nearly double the cost of the system in many cases so the plug-in option with 400 watts of panels etc gives you the best bang for the buck for sure. But it’s not legal or possible in many US states (though that is changing fast)
