12kW Energy Storage System Replaces Diesel Generator Power

Project Overview

In rural Kenya, many agricultural areas still lack reliable grid electricity. Farmers depend heavily on diesel generators for:

• Irrigation pumps
• Livestock facilities
• Farm lighting
• Cold storage systems

However, increasing fuel prices and maintenance costs have become major challenges.

A renewable energy integrator in Kenya contacted Zelinco Energy to develop a standardized Off-grid Solar Energy System that could provide stable electricity for agricultural applications.

The project required:

• Reliable operation in high-temperature environments
• Long-life battery storage
• Easy installation by local technicians
• Reduced dependence on diesel fuel

Customer Challenges

1. No reliable grid connection

The farm depended on diesel generators, with monthly fuel expenses exceeding USD 400.

2. Complex installation process

Traditional systems required independent installation of:

• Solar inverter
• Battery bank
• Controller
• Protection equipment

Local technicians found maintenance difficult.

3. Harsh climate conditions

High temperatures and outdoor operation required:

• Stable battery performance
• Long cycle life
• Low maintenance requirements

Customized Off-grid Energy Solution

Zelinco Energy designed a complete Off-grid Solar Energy Solution combining solar generation, lithium battery storage and intelligent power conversion.
