High Output up to 900VA with Fanless Design
The GR300P3 is a triple parallel unit consisting of three GR300 series inverters connected in parallel, achieving output up to 900VA while maintaining a completely fanless design. With no moving parts, the fanless architecture generates virtually no operating noise, making it ideal for system environments where quiet operation is essential.
Pre-configured Synchronization and Parallel Wiring
All input/output parallel wiring and synchronization settings are fully configured before shipment. No complicated initial setup is required, allowing immediate operation upon installation. In addition, the pre-configured design reduces the risk of failures caused by wiring or configuration errors, improving both system reliability and ease of deployment.
N+1 Redundancy
The system supports N+1 redundancy, helping prevent complete system shutdown even if one inverter unit fails. This enhances overall system stability and reliability for critical power applications.
19-Inch Rackmount Design
With a compact 1U height, the unit can be directly installed into a standard 19-inch rack. Its space-saving design allows clean integration into system racks while helping optimize installation space.
Integrated Rocker Switch for Unified Control
The unit consists of three inverters configured for parallel operation and features an integrated rocker switch that allows all units to be turned ON/OFF simultaneously. Since individual operation is unnecessary, system handling and operation in the field are greatly simplified.
Replaceable Fuse Board Integrated on Input Side
The unit is equipped with a built-in fuse board, eliminating the need for additional external fuses. In the event of a blown fuse, the user can easily replace it on-site, improving maintainability and helping minimize system downtime.
