I have a 240 V sub panel powering a well pump that draws 18 A steady state and 36 A at start up. The start up peak is very short - you have to keep trying to catch it on a current clamp/probe. The pump feeds a large cistern for cattle waterers. I have a manual transfer switch on the sub panel for a generator hook up. A screaming 3,600 RPM generator is annoying a close neighbor besides using a bunch of fuel. I'd like to go to an inverter/charger at 48 V for automatic backup. If there is an extended outage then I could connect an inverter charger to the transfer switch and hopefully run it much quieter as it will just be charging batteries. Load varies widely depending on how many cattle are where and what time of year, temperature, etc. Solar hookup to the inverter charger in the future would be nice. Suggestions on the inverter charger model? I will need to install something similar in multiple locations if all works well. Virginia location so cold to hot seasonal climate. Thank you!
