I'm on a hunt for an all-in-one off-grid power system for my shed, but it seems like I might be looking for something that doesn't exist yet! Ideally, I want a setup that includes a charge controller, inverter, and battery all in one package, like the Bluetti AC180. The catch is that I plan to use this system year-round, but most devices I find are designed to operate only above freezing (0 degrees Celsius). Does anyone know of a system that can handle lower temperatures?

Have you checked out the Pecron e1000lfp? It actually has a self-heating feature which could make it suitable for cold weather use. If that doesn’t work, you might want to look into a DIY setup with a self-heating battery instead.
While a true all-in-one unit with integrated battery heating might not exist yet, you could look into something like the EcoVault EV6500-S or the Fortress Power eFlex MAX, which can operate in colder temperatures and have some options for added heating pads. The eFlex MAX is especially scalable, which could work well depending on your shed's energy needs.
Many JK BMS units come with built-in heating control, so that's worth considering. You can also find DIY solutions that have heating elements included. Honestly, that might be your best bet unless we see more batteries that can charge in the cold.
