Before I spent any money, I would hire a PE with solar experience to give you an option. I doubt solar iinverters, which are current limited, would be a fault current issue. Usually fault current rating is a factor of the internal resistance of the secondary winding of a high voltage transformer. Solar inverters can't produce those kind of short circuit currents and are not a factor.
