I am guessing it is charged in parallel (actually small series in parallel) and delivered in series.

OK OK, I looked at the power wall...its a beautiful white fiberglass fluid dynamic shape, so yes all us sailboat guys love it on site, can just imagine it hanging on the stern of our 30 footer looking "tres kewl" (well maybe thats a little close to the salt water)
I agree if the thing has 400 v DC, use it! lots of industrial big DC motors out there that run on 400 DC, you can buy them cheap, or 3 phase AC.just be careful if you are swamping, you'll have another danger to seriously consider along with all the other things going on in that emergency.the thing i don't get is how(or why) it takes 220 volt current and charges the battery at 400V? must be stepped up and rectified at a loss, then to use it, it goes through a step down and inverter at another loss...and then theres also the loss of charging a battery....I wonder how many KWH's you put in to get one KWH back...how efficient is this electro econmically?If I had a bigger boat and docked with shore power, and had the dough to build an awesome system ....yeah...I'd go with the Musk Machine and a 20 hp dc.the 10yr garantee and maintainance contract thing may not apply to salt water environments
Where there is a shell, there is a way...
