@solar_chase@mastodon.green Wow. I actually didn't realise they used so little. I was expecting 3-4kW at least.
I don't have an aircon, and never have. They're not all that common in private homes here, so my only real experience with them is in office buildings.
I have practically my whole house running through the inverter, but not the geyser, dishwasher, stove/oven, electric kettle, or microwave.
My pool pump hasn't yet started for the day (it will in about 30 minutes from now), and right now I'm consuming a little over 500W. The pool pump alone takes around 1000W, so theoretically, that would still leave lots of room, until people start watching TV. In the afternoon, with everything running, I can be consuming a little over 2000W. Then you put the toaster on and it gets to 3000W. :-)
Which is still all well and good, but the kettle alone pulls 2000W, and even though that runs very briefly, it could still trip if I have all the other appliances on, and someone decides to run the microwave and boil the kettle at the same time, while the washing machine's running. :D
And, of course, at that point, the battery capacity would become an issue, because we don't actually have enough panels to run more than around 2500W, best case, in the middle of the day.
I saved about two years to buy my current inverter. They're pretty expensive here. To put it in perspective, I could buy 7 or 8 panels for what it cost for my inverter alone. And the battery costs about the same again as the inverter.
