Rules for using an inverter without letting the 12V battery go dead?
I have a 1500 W inverter. Ended up having to use it for a couple days on and off this winter. It worked well powering my fridge. I ran into trouble powering a space heater (was alternating between the two) for an extended period that ultimately drew down the 12 V and had to jump it. For your planned use, you should be fine. Just be careful with your wire gauging to the inverter and also to the fridge. More on reddit.com

What happens to your system during a power cut?
A few different options but.. without a change over switch your house will be without power during a blackout - save for the socket they’re talking about. There are a few systems on the market that give whole-house coverage, such as GivEnergy’s All-in-One or the Tesla power wall. These function almost as an uninterruptable power supply - provided the load in your house at the time of the black out doesn’t exceed the max power of the inverter. Your installer MUST install an Earth rod unless your home already has one (such as a TT earthing system). There’s a third party gateway on the market too made by a company called eco-ess that will give whole house back up - provided your inverter has an eps outlet/function.. but these are £950 Ex vat alone plus fitting.

Please help - Inverter and Battery in Serious power crisis
If you are buying new inverter the lights and fan can be used. Air conditioner, smart TVs, Computer and refrigerator should not be used as the consumption is more even if you have 2 inverter and batteries. New inverter last upto 3 days or more if only lights and fan are used. When the power is there make sure to use less of those connected to the inverter so that the battery is not consumed unnecessarily. Dont have much idea but we have been using inverter for last 7 years so I have slight idea, we are planning to get another battery as well because ours can only last for a day now if there is a power cut. Don't get the cheap ones.. They won't last long Also, phones can be charged More on reddit.com
