beep-beep car is go posted:"a generator, but batteries instead". This is known as a UPS. Batteries + inverter = win. Line-interactive UPS systems have a switch that lets you flip over to the batteries when power goes out. Double-conversion is where the grid is powering your battery charger and your batteries+charger are always powering your inverter to power the load. This is how phone company stuff typically works, since they want zero downtime switchover, and double-conversion stuff gives very clean power. Line-interactive is what hospitals and stuff use, since they've got point-of-use batteries for stuff that needs it. Now, you can do this yourself with a big bank of batteries on a charger, then an isolation switch and inverter for the house. Off-the-shelf solutions that will power a house run at about $700/(hr of runtime), give or take.

surivdaoreht posted:Hey folks, The only dangerous gas you have to worry about is hydrogen if the charging gets way out of control. With a competent charger on the batteries it's not an issue. Hydrogen is really only a problem in enclosed spaces. If the batteries are just sitting in the cabin, you're actually safer than if you were to build an enclosure for them. If you do end up building an enclosure, a small vent to outside would be fine, as long as the vent can't get clogged by bugs. Lead Acid batteries do best at around 20C, and fully charged batteries freeze around -40, discharged batteries freeze near 0C.
