Hybrid Energy Telecom Power System With Solar Power Grid Diesel Generator Battery For Outdoor Telecom Site Power Supply

Solar Power Grid Diesel Generator Battery Hybrid Telecom Power System for Outdoor Telecom Site Power Supply

1. Introduction

ESTEL Hybrid Energy Telecom Power System is a hybrid power supply solution that uses solar energy, diesel generator (DG), and grid power as the main power sources for telecommunication equipment.

It uses clean and low cost clean energy power to constitute a reliable power system, it provides high quality power for modern telecommunication services, and help telecom service providers to expand their business in those areas have no grid power, or have unstable grid power supply.

2. Applications

• 4G and wireless telecom base station
• Outdoor network application
• Transmission switching station
• Emergency communication

​

3. Telecom Power System Structure

It is composed of an outdoor telecom cabinet, telecom power system, a cooling system, batteries an environment monitoring unit and sensors.

1) Cabinet Enclosure - Features
