Frequently Asked Questions
•What is the typical operating temperature range for this inverter model?
Consult the manufacturer's datasheet for the specified operating temperature range. Exceeding this range can cause performance degradation or shutdown.
•How do I perform a PV string voltage test safely?
Use a calibrated multimeter rated for high voltage. Wear appropriate PPE, including safety glasses and insulated gloves. Follow all safety procedures outlined in the inverter's installation manual and NEC Article 690.
•Where can I find the latest firmware updates for this inverter?
Visit the manufacturer's website or use the inverter's monitoring app. Follow the update instructions carefully.
•What are the NEC requirements for Rapid Shutdown (RSD)?
NEC 690.12 requires a means to rapidly shut down the PV system in case of an emergency. This typically involves a disconnect switch located within a specified distance of the array. Consult NEC for the specific requirements in your jurisdiction.
•What is the typical AC voltage tolerance for the inverter?
Typically, the AC voltage tolerance is ± 5% of the nominal voltage (e.g., 120V or 240V). Exceeding this tolerance can cause the inverter to disconnect from the grid.
