Actually my mini splits pulls according to specs 3500ish watts at max heat which is highest. Now it will seldom run at max. We have residential fridge, older unit, came with Teton. Believe folks figure 600 watts for this but it not all the time either. Convection microwave, tv, computers, etc. I can see 8-9k on occasion. That why I considering 2 5k units. And I must confess, the more I read on the programming of the Victron multipass, the more complex this system is. Considering 2 Magnums but loosing some wattage with them. 8800 watts vs 10k watts.
