Hey Esteemed Wrenchies,

Does anyone know if manufacturer's are using any common standard for AC 
Coupling frequency shift algorithms?

Is it part of any UL standard?  Seems like since it's a battery charge 
control issue it needs some rigor?  Are manufacturer's just copying each 
other?  Did SMA's Sunny Island/Sunny Boy set that standard?
