Running your welder off solar?
Discussion
Not for any serious length of time at the moment, but, yes. That's possible with more battery and the rest of the system built out to support the current draw.
Wow. That's quite a draw! Interested to learn how it goes!
I have a small 200A capable welder. Max rated inrush is ~40A for a short period. (not enough to trip a 20A 120V breaker, and it's a bit less when running on 240V.) bigger welders are much, much more thirsty. This is why you cannot go poking about willy-nilly in the guts of a welder, since the caps are beefy and can easily kill you. But it makes a really good test of the system.
Let us know how it goes!
(I'm very trepidatious about mixing high-current tools and inverters ever since I blew up my first inverter by using a corded drill that should have been well under its limits)
Motors can be very electrically noisy with many transients and spikes. The welder is an inverter based unit, so, I don't expect any issues, to be honest.
