The cell has a voltage discharge curve way outside that of RE equipment, 1.75 Vpc down to 0.5Vpc. I can't see how this technology could be scaled to RE applications without wasting much of the capacity. From what I see, only about 40% could be used before LVD.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>And this:<o:p></o:p></p></div><div><p class=MsoNormal><span style='background:white'>The Aquion battery claims their 2.4kWh, 48 volt stack operates from 59 to 30 volts. Many inverters have a LBCO of 1.75 Vpc (42 volts). Depending on voltage sag, that means about half of the capacity of the Aquion battery can't be used. Even if the outback can operate down to 1.5 Vpc, you are still not able to use the full capacity of the battery unless your load is less than 800 Watts. </span><br><br><span style='background:white'>I have reviewed their technical presentation and it looks to me like the capacity simply can't be used in the off grid environment. If you can't use it, why do they rate it at 2.4kWh?
