FAQ :

Q: Can this inverter run on a 125VDC telecom battery bank?

A: Yes, it is specifically designed for 125VDC nominal input (compatible with lead-acid or lithium DC screens) and outputs stable 220VAC 60Hz.

Q: Does it support remote monitoring?

A: Yes, standard RS485 and optional SNMP allow real-time monitoring of voltage, load, and status via NMS.

Q: What happens if the DC fails?

A: The built-in Auto Transfer Switch (ATS) seamlessly switches to AC mains bypass (220VAC IN) to keep the load powered.
