There is a similar unit from China produced by Setec Power. A search using Setec will result in some actual use information. It does not appear any of these units are suitable to integrate with the typical US household 240 VAC split phase power. Personally have thought about purchase, however, waiting for an integrated solar/EV hybrid grid tied power converter system (V2X). OTOH, not holding my breath!
