*happy noises*

I swapped out the latest MPP 3048LV-MK for testing, and everything seems to be functioning perfectly.

The original unit got pulled apart to install the parallel board.

I'm nearly ready to test both units for 240V split phase output. Though, I have to remember to order/buy an outlet for my welder since that's the only thing I've got handy that can run on 240V. This is getting to be so much complicated fun!

A gc-12 battery bank is as far as i have made it so far. I have intentions to add some type of solar panel eventually but i am definitely behind the curve as far as basic solar system knowledge, do you reccomend any good resources for getting started and learning the basics???

Will Prowse (and his forum) and The Off Grid Garage on YouTube.

Plenty of others but...

Doing anything other than DIY "48V" systems is silly in nearly all cases. Hit me up if you want to know more.

Got it. Ty

Running your welder off solar?

The Beave 1y ago

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.

Low Information Voter 1y ago

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)

The Beave 1y ago

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.

Low Information Voter 1y ago

Very true

The Beave 1y ago

Yup. But also, the inverter portion of these units are very robust. If I do pop one... I trust the seller to make it right.

Low Information Voter 1y ago

Even better :)

The Beave 1y ago

Yup. Worst case, I chuck it all and spend eben more money... LOL
