Contact my friend Harry at [email protected] ( https://squareup.com/store/wirlnet-com). He builds larger systems, but may have a smaller one too. In any case, he knows the lay of the land and what is good and what is not. Tell him I sent you.
I use 12V LiFePO4s which keep the voltage up (>12V) much longer than Lead Acid and weigh less. I've got them in sizes from 3 Ah for backpacking with my KX3 to 400 Ah in our RV running my KX3 and a big inverter for my KPA500. Morningstar has a bang bang mode on some solar controllers that don't output much RFI. 73, Mark W7MLG On Sat, Jan 4, 2020 at 3:24 PM Wayne Burdick <[email protected]> wrote: > I finally installed a single 50 W, 12 V solar panel on the roof for light > backup purposes -- phone/pad/laptop/flashlight charging, natural-power use > of the KX2/KX3, etc. Connecting the panel directly to automotive-style USB > chargers works great when the sun is shining. > > My 15 year old thinks it's cool.
