Default Trip Limits and Times According to IEEE1547
NOTE
The inverters are equipped with adjustable utility protective function set-points, and can be aggregated above 30kW on a single Point of Common Connection.
The default settings are in compliance with IEEE1547. Utility authorization is required to change these set-points.
