Overview

Based upon its proprietary battery technology, the Cat® Energy Storage Solution (ESS) is capable of covering ultra-long outages to full depth of discharge. The core system is tolerant of high temperatures and unaffected by frequent long or short power cycles. The Cat ESS provides reliable, long duration uninterruptible power for telecom BTS and microwave backhaul operations. The Cat ESS is designed to interface directly with the existing -48V DC bus and is compatible with all -48V rectifier equipment for its charging needs. It can be used with all on-grid AC power configurations either with or without an installed backup generator set.

Technical Summary

Units:
Rated Power 1.5 kW to 4.5 kW 1.5 kW to 4.5 kW Less
Energy Storage Zinc-air cells Zinc-air cells Less
Application Targeted at telecom applications that are subjected to a severe load shedding grid environment. Targeted at applications with poor, erratic electrical service that consists of random, non-scheduled outages or areas where scheduled, rolling utility outages occur. Typical applications include installations where scheduled, rolling regional utility outages occur every 1-2 hours continuously during peak hours and off-hours.

Environmental Parameters

Enclosure Rating IP 55, suitable for outdoor installation IP 55, suitable for outdoor installation Less
Operating Temperature 0°C to 50°C 0°C to 50°C Less
Storage Temperature -20°C to 50°C -20°C to 50°C Less

Vertically Integrated

Energy storage, electronics, and software developed on a single platform to maximize integration between components.

Proven Technology

Over 35,000 batteries are deployed with telecom customers, setting new reliability levels.

Clean and Outdoor

No lead is used in manufacture of the energy storage cells. The ESS operates in a broad temperature range (up to 50°C) without the need for additional cooling.

Extended Run-time

4 to 20 hour discharge capability enables energy storage systems to meet any telecom environment and power challenge.

Scalable Architecture

Module architecture makes it possible to scale energy and power capabilities to meet future site load growth.

Predictable Performance

The Cat ESS cell life is unaffected by high temperatures. There are no depth of discharge or cycle life limitations on the service intervals for the system.

Theft Deterrent

There is no theft value of the equipment in the system. Cells will not operate when removed from the system and contain no valuable material.

24/7 Remote Monitoring

Full site performance and site reporting is available; provides critical information on the installation, including total site availability, equipment status, and utility performance.
