The breakers meet the code requirment for overcurrent protection and
disconnect of the inverter, but they don't protect other breakers such
as are used on the DC distribution or PV input.

The Heinemann GJ breakers are not current limiting and cannot be used to
protect breakers with a lower AIC. Same goes for the CD breakers that
Trace sells.

I find it frustrating myself.

> How about QO 15 amp breakers?

The 15 A breakers are OK. As far as I know.
