CNTE Successfully Commissions STAR-Q Hybrid C&I Energy Storage Project in Johannesburg, South Africa

Johannesburg, South Africa — Contemporary Nebula Technology Energy (CNTE), a global provider of integrated energy storage solutions invested by CATL, has successfully commissioned a STAR-Q 50kW/109kWh commercial and industrial (C&I) energy storage project in Johannesburg, South Africa.

The system has been deployed to support a bag manufacturing facility and adjacent residential units, operating under challenging and unstable grid conditions. The project integrates multiple energy sources into a unified hybrid power architecture, combining solar photovoltaic generation, diesel backup, and battery energy storage.

The installed solar system consists of 90 × 540Wp PV modules (48.6kWp total capacity, covering approximately 232.6 m²), working in coordination with a 33kW diesel generator and CNTE’s STAR-Q hybrid energy storage system. This configuration enables flexible energy management across both grid-connected and off-grid operating modes.

Designed for regions with unreliable grid supply, the STAR-Q system ensures continuous and stable power delivery by intelligently balancing solar generation, diesel input, and battery discharge. This hybrid structure significantly reduces reliance on diesel fuel, lowers operating noise, and improves overall energy efficiency for the customer.

Powered by CATL lithium iron phosphate (LFP) battery cells and built with multi-layer safety protection architecture, the system delivers high operational reliability and long-term performance stability even under complex working conditions.

By optimizing energy usage and reducing fuel consumption, the solution provides clear economic benefits while supporting cleaner and more sustainable operations. The integration of renewable energy and storage also enhances energy independence for both industrial and residential loads on site.

The Johannesburg project demonstrates CNTE’s capability to deliver flexible hybrid energy storage solutions tailored to real-world off-grid and weak-grid environments, particularly in emerging markets where energy reliability is a critical challenge.

As global demand for resilient and decentralized energy systems continues to grow, CNTE remains committed to advancing intelligent hybrid ESS technologies that enable safer, more efficient, and more sustainable power solutions worldwide.
