Core Advantages

Six Core Advantages

Specially designed for harsh power environments, stability, reliability and intelligence are our core commitments.

01
Modular Rectification & Hot-Swappable
Rectifier modules support online hot-swapping replacement; single module failure does not affect system operation, and maintenance is carried out without power interruption.
02
Intelligent Battery Management System (BMS)
Real-time monitoring of voltage, temperature and internal resistance of each battery, intelligent equalized charging, and accurate early warning of faulty batteries.
03
Dual Input & Seamless Switching
Supports dual AC input of mains power + diesel generator; switches to battery power supply in milliseconds when mains power is interrupted.
04
Remote Monitoring & Cloud Platform
Connected to DenbyePower Cloud Monitoring Platform, check operation status and alarm information anytime via mobile/PC, support SMS/WeChat alarm push.
05
N+1 Redundant Design
Rectifier modules are configured in N+1 mode; the backup module automatically takes over the load in case of any module failure.
06
Wide Temperature Range & High Adaptability
Operating temperature range -25℃~+55℃, high humidity resistance (95% non-condensing), suitable for harsh environments such as outdoor cabinets and substations.
