1. Project Overview

In response to Cameroon’s persistently unstable national grid, which experiences daily power outages of 6–8 hours, Highjoule(HJ Group) successfully deployed a bespoke domestic photovoltaic energy storage system for a local household. This initiative not only alleviates the household’s electricity challenges but also demonstrates the company’s comprehensive capabilities in technology, logistics, and installation across Africa.

2. Project Specifications

Application

The system primarily safeguards essential household electricity needs during grid outages or rationing, covering critical loads such as lighting, appliances, and small electronic devices. This significantly enhances living standards and electrical safety.

Energy storage inverter output: 5 kW

Battery storage capacity: 5 kWh

Key Equipment

5 kWp solar photovoltaic modules

5 kW integrated PV-storage inverter

5 kWh lithium-ion battery storage system

Roof-mounted aluminium profile brackets and professional installation accessories

3. Project Advantages

Enhanced power supply reliability: Maintains essential household electricity during grid failures or rationing.

Enhanced Economics: The ‘self-generation for self-consumption + energy storage’ model reduces reliance on costly, unstable grid electricity, lowering electricity expenditure.

Environmentally Friendly: Utilises clean energy, reducing fossil fuel consumption and supporting local sustainable development.

High Adaptability: Provides a distributed energy solution addressing Cameroon’s ageing grid infrastructure and transmission/distribution bottlenecks, offering strong potential for widespread adoption.
