Benefits and Features

Equipment

The Cat® Energy Time Shift (ETS) system is a compact hybrid energy system designed for telecom and other DC voltage applications. It integrates with multiple energy sources such as solar power, electrical utility/ grid (where available) and generator set. This will enable ETS system to utilize the stored energy when the renewable source or electrical utility/grid is unavailable or not sufficient to meet the site load.

Technical Summary
Application	Peak Shaving
Module Type	Energy Time Shift
Nameplate Power	24 kW DC Output
Nameplate Energy Capacity	up to 150 kWh

Reliable, Modular and Compact

ETS system allows easy installation of solar power controllers, rectifiers, inverters, batteries, protection and communication hardware in a single robust cabinet.

The cabinet is engineered with a modular configuration to allow field installation of additional hardware to manage growth of in-site energy requirements.

Power Integration

The ETS unit is designed to integrate solar power generating system with any available grid, battery and a standby diesel generator set where required.

IP55 rated outdoor cabinet contains both power control and distribution equipment with space for suitable batteries to store the generated energy for use when grid and solar power are insufficient or unavailable.

System Controller

Manages system parameters and allows real time remote access to all system data.

The controller can store system data and provides a touch screen interface for ease of installation and servicing operations.

Solar Charge Controller

Maximum Power Point Tracking (MPPT) controllers are designed to maximize energy extraction, conversion and minimize inefficiency.

Rectification (AC to DC Conversion)

System has space for multiple rectifier shelves for holding a rectifier control module and rectifiers.

The number of rectifier modules can be changed in the field if the generator set needs to be upgraded for future load demands.

Energy Storage

Advanced lithium-ion batteries provide energy density, high discharge/recharge efficiency and long life cycle.

Remote monitoring of battery condition and performance.
