Trying out a brand new Phoenix 12/250 on the test bench. Hooked up 12V from a lead acid battery though a 30A blade fuse, 10mm2 cables.
It has no problems running lights.
Next I hooked up a small fridge, usually draws about 70W, so I expected it to be with a good margin to the inverter's max.
Then, when switching on, a short brrr and then a snap from the fuse.
Manual seems not to recommend a proper fuse, only that it internally has a 60A, but I like to have fuses close to the battery.
@mogul your small fridge is likely to have a start up current of 10 times the running current.
You will never get it running using a 30a fuse.
Your unlikely to get it running with a 250va inverter.
My 55-65w fridge will draw up to 80a @ 12v to get running.
Ahh, then it make sense. Good. I will run a few more tests before deploying the unit on the boat where it will mainly charge laptops.
Thanks
