4 FAQs about Solar inverter blocking wave requirements

Are Sungrow inverters compliant?

All Sungrow's inverters are compliant with the standard AS/NZS 4777 related to grid protection requirements. Those standards dictate for example, that if the line voltage or frequency goes outside pre-determined parameters, the inverter must shut down and decouple from the grid. This also includes blackouts.

What is the voltage requirement for a solar power conversion system?

For the example solar power conversion system, the AC phase-to-phase voltage is 480 VRMS, the DC link voltage is 1500 VDC, and the open circuit voltage of the PV panel is 848V DC. With the open circuit voltage of 848 VDC, the surge voltage requirement is determined to be 4000 VPK.

Are solar inverters safe?

Any solar inverter installed without robust anti-islanding capabilities is considered a safety liability. Beyond safety, anti-islanding protection is essential for regulatory compliance. Grid-tied solar systems must adhere to national and international standards to ensure safe integration with the electrical grid.

Do solar power conversion circuits need a basic isolation?

In the solar power conversion system (Figure 1), the isolated gate drivers and isolated voltage and current-feedback circuits both need to support reinforced isolation. Basic isolation is suficient if another basic isolation is inserted through the isolated data links.
