[DisasterRadio] MPPT / Solar

Hi all I've been looking into solar a bit, in the process, I came across this MPPT: https://www.aliexpress.com/item/4000031728632.html The 2.9v cutout should mean the battery lasts a reasonable timeframe. This is the list of bit's I'm going to test for a solar node: https://my.aliexpress.com/wishlist/wish_list_product_list.htm?&currentG… It comes to around $70 per node. It should only require a screwdriver to assemble. I'm estimating the battery has half it's stated capacity, but that should still be adequate. The 'oversized' 10w panel should work with the MPPT even on foggy/ cloudy days. This is untested as yet, but I'll do some testing soon. Thanks Sam
