I bought and installed the Victron 1200/48. Works great! 24 hours the 3cuft freezer chest used only 240 watts! It surges to 700w for a split second, which my victron 375 couldn't handle, and then sits at 40w for about 10 minutes. I think it turns off quickly.
The more steak and chicken I buy, the more efficient it becomes!
Freezer chests are amazingly efficient and work great for off the grid so you don't need to go to town all the time for groceries, and you can buy things on sale and in bulk. This will save me a lot!
I still wish there was a cheap soft start solution, my 375VA would handle it. It sucks I had to pay $400-500 for the 1200VA version
