Karl, you're interconnecting into a spot/area network, right? It's a
real concern; some solutions and background on the issue here:

Esteemed Wrenches,
We've recently run into an issue with a local distributor citing
network fault current on a split-phase service as a reason to prevent
interconnection of our customer's solar array. They've given us the
options of reducing our system size from 36.5kW-DC to 15kW-DC, or
having the customer upgrade to 3-phase at a soft price of $20-30K.
We're looking at 32kW of inverters on a 167kVA transformer.
Does anyone have experience on circumventing the issue of network
fault current? Any experience with Fault Current Limiters?
Much appreciated,
