I bought some cheap panes on Ali express. I think the battery controller was $.99 the inverter was a couple bucks. I run a small, cheap mini split off it ($500 retail in the us). Strangely I wasn’t able to find a dc powered mini split. I guess they make em for RV use but they’re more than twice the price of the one I bought. My whole system is off grid. I run 12v lights and even have a redundant battery system. You can do lot with cheap Chinese parts.
