Super budget/DIY energy hacks (lemmy.world)

I just recently started using a solar charger to charge a 10k mah battery pack that I use to charge my phone every night. One device “off the grid.”

Short of installing solar on my home I’d really love to be able to charge a large battery that would output 120V so I could use household appliances “off the grid.”

Does anybody have some other energy hacks, or ways to reduce your energy consumption at home that’s not just “use less energy?”

That’s cool! How much did that cost and where and when?

Umm around 2022ish, the solar panels were free from the tip, the batteries were also free form a mine site(collapsed cells could hold 12v but couldn't crank out high amps), solar controlers were from eBay 150 bucks or something and a 5000w inverter was 600ish from memory also probably about 200 bucks worth of battery cable and connectors,
