<br>
Does anyone know if manufacturer's are using any common standard for AC
Coupling frequency shift algorithms?<br>
<br>
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?<br>
<br>
Curious!<br>
<br>
Best<br>
