What grid types does the X1-VAST inverter support, and what AC voltage/frequency ranges are compatible?

The inverter supports three grid types: TT, TN-S, and TN-C-S. For AC parameters:

• Nominal Voltage: 220 V / 230 V / 240 V (single-phase, L/N/PE wiring).
• Frequency: 50 Hz or 60 Hz.
• Grid Compliance: Ensure grid voltage and frequency stay within the inverter’s allowable range (consistent with local utility standards) to avoid grid-related faults (e.g., overvoltage/undervoltage, overfrequency/underfrequency).
