SMA absolutely operates solely on Batt SOC. In
fact, the Germans pride themselves on their "superior" SOC management,
and have convinced some battery manufacturers to extend the battery
warranty based on this "superior" SOC management.See Ya! Marv Enphase Energy 707 763-4784 x7016 Darryl Thayer wrote: I agree absolutly. But Outback and Apollo are the only systems that monitor and control on SOC. Apollo can operate a relay, and Outback can change settings using the FMDC. I think both systems with a few tweeks are the better way to handel AGM.

If they are low then you can push the voltage up but if they are in an intermediate indeterminate state as with most small renewable energy systems then you don't know what to do. Playing safe can mean that the battery does not get a proper charge (I am told). |
