HOLY SMOKES HEY WILL!!! Love your videos! I personally had no issues with the fuses in the 6 years I've owned my 1250. Granted the most I ever pulled out of the chaining port was probably around 130 amps when I used it to run a 1.6kw Northern Tools inverter as the 1.2kw inside wasn't enough for a time.Holy cow. I would not trust that. I have a hard time trusting 30A fuses in that size..
But I agree. Even though in theory Goal Zero tested the 50 amp fuses and they must have performed fine, pushing a combined 200 amps through 4 of those standard fuses probably isn't great, another reason I lowered them to 30 amp fuses when I replaced them.
