I'm not defending the utilities. They definitely have their faults
(argh, argh), but they have some severe challenges that we are not
always sensitive to.<br>

It was my understanding that in special circumstances, inverter
manufacturers are allowed to widen the allowances for specific
units. IIRC, a letter from the utility was required. In some
inverters, a change of firmware with the more liberal settings does the
job. My memory is subject to verification.<br>
