Transient Overvoltage Management

Customer generation systems shall not drive overvoltage conditions during a fault (short-circuit). To ensure this, generation systems should either use inverters which comply with the latest IEEE 1547 standard, or be effectively grounded. If the total generation on a circuit is less than 10% of the circuit's minimum load (daytime minimum load for solar generation), we can waive the requirement.
