You can buy 256Wh battery banks for around $150 now. You can pair them with a timer for charging/topping off at night when electricity is cheap. They even accept solar input.
Throw one in every room and between appliances like the fridge or oven. Now you have a UPS for your whole house and the cheapest energy rates throughout the day.
- epistasis 3y agoDo those have an inverter built in? If not, at $600/kWh very pricy compared to what this guy used at $190/kWh for batteries, or $360/kWh including the inverter: https://www.amazon.com/dp/B08G81TKC6?ie=UTF8&th=1&linkCode=sl1&tag=gridlesskits-20&linkId=33ade7afc845a76a2271b39f1e6ed35a&language=en_US&ref_=as_li_ss_tl https://www.amazon.com/dp/B08G81TKC6?ie=UTF8&th=1&linkCode=s... Also, $190/kWh is so cheap. Its hard to believe how fast costs are falling for energy storage.
- ianburrell 3y agoIf is he talking power bank, then big ones, usually called power stations, have inverters. But they can’t be used as UPS since they cut power when switching sources.
- grobbyy 3y agoMy experience is that power banks and UPSes fail more often than my power. I keep a couple charged, but with nothing plugged in. I sometimes plug things in before a major storm, planned outage, or after an unplanned one.
- smeej 3y agoThis is funny to me because mine just died unceremoniously during a snowstorm and it made me realize there should really be a testing cycle built in.
- xyzzy123 3y agoHm fridge sure, but oven? 256Wh is going to power an electric oven for like, 5 minutes. Doesn't seem useful.
