Hi Jeff Thanks for the info.
As to out of balance 120v. How are you configuring for that? Just putting potential problem loads on the xformer or ? Which transformer are you using with a 9kw inverter? Most I’ve seen are only 5-6kw. And as many people are using the sol ark, a question about repairing. Is it possible to repair in the field? Has anyone actually done it? If not field repairable, how quickly/easily is the repair/warranty process working Thanks Jay > On Jan 6, 2022, at 9:04 PM, Jeff Clearwater <je...@villagepowerdesign.com> > wrote: > > We just ordered a 3 Sol-Ark system with 16 Storz Power batteries I'll let > you know this Spring once I have it up and running.
