Does anyone know about authoritatively about G99 Approval?
When exactly does it have to be sought? When the sum output of the building goes above 16A/phase?
Does (G100? I think) limiting the output to 16A/phase mean it’s not needed?
If, say, a storage battery has an output of 16A and PV has an output of 16A, is it be needed?
Even if the battery will not output power when the solar does?
What if the output of the battery is 23A? That would require G99 on it’s own?
In my searching I’m reading several different versions of when it applies.
