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. He wants me to turn the mains breaker off for a whole day so we can get the full off-grid experience :) To facilitate that more rigorous purpose, I'd like to add a modest battery pack, say 10 to 20 AH, that is charged by the PV panel without intervention. The charger has to be compatible with simultaneous charge/discharge, i.e. we may need charge USB devices at the same time the PV panel is charging the battery. The battery voltage should be 11 to 12 V minimum after any controller drops so it'll work with the radios. I could cobble something together from several different vendors, but I'd prefer to purchase system components that are already proven, reliable, and reasonable in cost. Any recommendations? tnx Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
