Comment on solar PV → heat pump → water heater; direct, no A/C or intermediate components. Practical? Feasible?
perestroika@slrpnk.net 4 months agoP.S. I have once used DC to power a pump “directly”. I use quotation marks because the pump (a water pump) was a brushless DC motor with an integrated controller. I used it on a field for removing water after a spring flood. Its controller accepted 24…48 V input, and it was powered from a 40 V solar panel brought on a wheelbarrow. :)
