Today the battery charger on our off-grid system bit the dust. It was an old 50 amp RV Converter, so it didn't owe us anything. We are looking at a few options for it's replacement. An all in one Inverter/Charger/Transfer Switch looks attractive right now. We had hoped to find a Trace SW2512, but they seem to be gone forever. The Outback 2812 is $2500, way over our budget. We found a Xantrex Prosine 3.0 that's closer to what we can scrape together. Meanwhile the batteries are dead, and we are on gen power, as it's been raining today and no sun. It looks like we will just shut everything off for a few days and step back about 100 years.
