Have a look at https://www.superlecdirect.com/ at their Tri Rated cable.Yeah I'm UK based, I've been using simply split charge for cables but there expensive. A link to cheaper ones would be handy. Thanks
I've been sat pricing up the things I need to go with the inverter, dishwasher, microwave and possibly a bread maker but that means new water tank, inline pressure valve, using the old tank as a waste tank, redoing the waste drainage all before I look at microwaves. Just as well I don't drink coffee and don't need a coffee machine. All in about £500 plus the price of the inverter or I could buy a converted power supply as a charger and carry on hand washing the dishes and heating things on the cooker. Hmm decisions decisions
When you see UK companies use words like over rated/over sized cable, there is a good chance they are selling you metric sized cable that they are buying from Superlec but they are charging twice the price. The same goes for UK seller on ebay. They quote AWG sizes but go on to say the cable is over sized.
You really need a minimum 100mm2 cable to pull enough power to run a 12v inverter close to 3000W.
You wont need much of it because you want the inverter as close as possible to your battery.
You also want something like a 250A breaker (or 250A Mega fuse) between your battery and inverter.
I'm buying 120mm2 (4/0 AWG) which is £20 per meter with the VAT, to go from my battery to the 3000W inverter.

All the bits like cables and lugs and breakers add up. So if we can save a few quid it's a bonus.
You could go for 95mm2 tri rated (3.0 AWG) if you not pushing the inverter right up to 3000W continuous.
You really need to put a clamp on the 240v appliances to see how many watts they pull on start up and continuous.
A lot of people think an 800w microwave uses 800w max but they often pull more than double that on start up.
