Why not use a 48VDC system and a compatible DC-direct welder?

This new formulation addresses some of the previous problems with the prior generation of LiPo batteries and will be a plug and play installation, just like liquid lead acid or AGMs are presently. All of the benefits of LiPo technology like deep draw capability (80%), extremely long life (5000 charge cycles = 10-15 year battery life), and the ability to charge at below freezing temperatures.
These new beauties are being field tested now and should be available sometime in the first quarter of 2015.

A bank of solar panels,3 inverters one for each phase should get the job done along with some 120v AC batteries to store all the extra power and stop any surges.

I have a friend who is a wandering RV tech and runs a semi (small Freighliner) pulling a gimormous 5th wheel. He uses a 24VDC welding apparatus directly from his chassis batteries (also 24VDC) when his diesel is on high idle. Works like a charm.....so it's totally do-able!!!!
