Who, What & Where

  • Trojan Battery Company
  • Microgrid powered by batteries with renewable energy & backup power
  • Les Anglais, Haiti

The Company

Founded in 1925 by George Godber and Carl Speer, Trojan Battery Company is the world’s leading manufacturer of deep-cycle batteries. From deep-cycle flooded batteries to deep-cycle AGM and gel batteries, Trojan has shaped the world of deep-cycle battery technology with more than 85 years of battery manufacturing experience.
With the invention of the golf car battery for the Autoette vehicle in 1952, Trojan pioneered the development of deep-cycle battery technology for the golf industry; successfully introducing mobilization to the game of golf. For 
Trojan, this began a legacy of leadership and innovation that prevails today in the global, deep-cycle markets spanning applications for golf and utility vehicles, renewable energy, transportation, floor machines, aerial work platforms, marine and recreational vehicles.

The Challenge

The majority of Haiti has little to no access to grid power, and the town of Les Anglais was no exception. Thanks to a grant EarthSpark International received from the 'USAID Powering Agriculture: an Energy Grand Challenge for Development,' the organisation was able to implement a hybrid microgrid for the Les Anglais community.

Renewable Solution

Establishment of clean energy micro-grids worldwide is increasing to supply power to remote villages not connected to the main electric grid, or only have access to electricity a few hours a day.  A battery-based microgrid system ensures these areas have access to energy 24/7, enabling remote communities to operate lighting, communications, radios, TV and other electrical appliances.  Access to electricity also enhances productivity of local businesses and fosters the development of new commercial activities. 

This microgrid is the first of its kind in Haiti and includes 92 kW solar PV, a 400 kWh battery bank, and small backup diesel generator. Smart meters developed by SparkMeter serve residential and commercial customers, including agricultural processing facilities. After three years of feasibilities studies with a small group of customers, EarthSpark was ready to implement the SparkMeter system for the Les Anglais microgrid.  EarthSpark’s microgrid provides reliable electrical power to the community which consists of 430 households, businesses and farms, and the downtown area of Les Anglais.

The 92 kW solar PV solution is supported by a 480-volt battery bank container solution from Trojan Battery featuring 152 deep-cycle gel batteries with 38 batteries per string. Both the system’s inverter/charger and charge controller are provided by Princeton Power Systems.

Deep-cycle batteries are key components in photovoltaic applications to provide reliable energy storage. Batteries improve the reliability of microgrids, reducing operating costs of fuel consumption, fuel transportation, and maintenance of diesel generators. Selecting the right battery technology and type, as well as selecting the right vendor play an important part in implementing a successful project. 

ZeroBase, a key project partner in charge of installation and commissioning of the microgrid, chose Trojan batteries based on their reputation for high quality and reliability, as well as Trojan’s experience in the region.  Trojan worked closely with ZeroBase to ensure the best battery technology was selected for the Les Anglais microgrid installation. 

Clean microgrids are crucial to provide electricity in remote towns and regions around the world. It’s the first stepto increasing the comfort, productivity and well-being of residents that would otherwise have limited opportunities.
