Regulatory Compliance
The GT Inverter is compliant with the standards described below.
• Safety: Regulatory Compliance Mark (RCM) based on compliance with AS/NZS 3100 Approval and
test specification – General requirements for electrical equipment
• Electromagnetic Compatibility (EMC): RCM mark based on compliance with:
• EN61000-6-1 Generic standards – Immunity for residential, commercial, and light-industrial
environments
• EN61000-6-3 Generic standards – Emission standard for residential, commercial, and light-
industrial environments
• EN61000-3-2 Limits for harmonic current emissions
• EN61000-3-3 Limitations of voltage changes, voltage fluctuations, and flicker
• Interconnect: ResLab verified, compliant with the following:
• AS 4777.2-2005 Grid connection of energy systems via inverters – Inverter requirements
• AS 4777.3-2005 Grid connection of energy systems via inverters – Grid protection requirements
The GT Inverter is designed for utility interactive operation. It has complete on-board over-current, over-
temperature and anti-islanding protection. It monitors voltage and frequency of the utility grid and
automatically stops supplying power whenever conditions on the utility grid deviate from standard levels
(see Specifications).
The GT Inverter is equipped with a high frequency transformer that assures galvanic isolation between the
DC side and the utility power grid.
PV Ground Fault Detection
The GT Inverter is equipped with a ground fault detection circuit that measures the impedance to ground of
the array, before connecting to the grid. If a high impedance is not detected, it signals a fault and refuses to
connect. The GT Inverter will remain faulted until the ground fault is remedied and the inverter is
manually reset. See Table 6-1, “Troubleshooting the GT Inverter” on page 6–4.
