RMI-M Series Inverter

Product catalog summary

Overview: The RMI-M Series Inverter is a modular, parallelable inverter designed for high reliability and flexibility, suitable for 110VDC and 220VDC systems with a power range of 1-80KVA.

Key Features:

Digital Control: Utilizes 32-bit DSP and high-frequency SPWM technology for accurate control and pure output waveform.
N+1 Parallel Redundancy: Allows for a power system with module backup, enhancing reliability.
No Master-Slave Technology: Each module operates independently, eliminating single points of failure.
Hot Swap Support: Modules can be replaced or added without configuration, simplifying maintenance.
Built-in Module Bypass: Users can select between inverter or bypass operation.
Monitoring Management: Includes an indicator panel, fault alarms, RS485 communication interface, and fault dry contact.
Protection Functions: Features input anti-reverse connection, undervoltage, overvoltage, output overload, short circuit, and overtemperature protection.
