I'm on the hunt for a good solar generator that can power my 12000 BTU air conditioning unit. I estimate that it might need around 600-700 watt-hours, though I'm not entirely sure. My AC really drains my power bill, especially with a scorching summer ahead. Can anyone recommend a solar generator setup or share some advice?

Definitely aim for a 2000 to 3000 watt inverter if you’re using a standard window unit. If you’re thinking about a DIY approach, check out this helpful video I found: [https://youtu.be/2Qh14pX3IxA](https://youtu.be/2Qh14pX3IxA) for ideas. Just keep in mind the inrush current when choosing your setup; it can really add up!
The key challenge here isn't just powering the AC, but starting it. You probably want an inverter that can handle around 3000 watts for short bursts since running the AC might push it closer to 900 or 1000 watts instead of the estimated 700. If your AC unit is an inverter model, starting it shouldn't be an issue, and you could get away with a smaller 1500 watt inverter.
I have a 14,000 BTU AC and it actually pulls about 1000 to 1500 watts depending on the temperature. The initial startup can hit 3 to 4 times the running wattage for a few seconds, which is tough on cheaper units. A good 2000 to 3000 watt setup is ideal. You could check out brands like LiTime or Ecoworthy for a solid 48V inverter/charger, which runs around $600. Plus, consider adding extra batteries to manage the startup draw.
