HUAWEI Inverter Module I23003G1I23003G1
Huawei Inverter Module I23003G1
1. Product Overview
The Huawei I23003G1 is a high-efficiency DC/AC inverter module that converts 48V DC power (from a telecommunication DC power system) into stable 220V/230V AC power. It provides high-performance, uninterrupted AC power for AC equipment in communication sites. The module supports hot-swapping for online replacement, features an intelligent speed-controlled fan, and supports N+1 backup configuration for system reliability .2. Key Features
High Efficiency: Peak efficiency ≥93.5%
Wide DC Input Range: 42V DC – 58V DC
Hot-swappable: Supports online replacement without system shutdown
Parallel Operation: Supports output paralleling for power expansion
Wide Temperature Range: -40℃ to +75℃ operation
Intelligent Fan: Built-in fan with temperature-controlled speed regulation
Comprehensive Protection: Overvoltage, undervoltage, overload, short circuit, overtemperature protection
Remote Management: Supports remote monitoring and management via communication system

8. Important Notes
Output Capacity Derating: Full 3000VA/2400W output is only available when DC input voltage is between 52V and 58V. At lower DC input voltages (42V-52V), the rated output capacity is 2500VA/2000W .
Temperature Derating: Linear derating applies between 50℃ and 75℃ (20% derating at 75℃) .
Altitude Derating: For altitudes between 2000m and 5000m, the maximum operating temperature derates by 1℃ per 200m elevation increase .
The I23003G1 is the newer model that replaces the older I23002G1 (2000VA/1600W). These two models are not interchangeable in system configurations .
