Client: Fantsuam Foundation
Location: Bayan Loko, Kafanchan, Kaduna State, Nigeria
Overview
Green & Smart Technologies Ltd completed the Fantsuam Foundation Central Solar System Upgrade in Bayan Loko, Kafanchan, Kaduna State, Nigeria. The project expanded the site’s existing central solar power system from 11.45 kWp solar PV, 10 kVA inverter capacity, and 15 kWh battery storage to 25.61 kWp solar PV, 30 kVA inverter capacity, and 45 kWh lithium battery storage.
The intervention was designed to strengthen system capacity and improve power distribution within the facility. Works covered rooftop solar panel installation, wall-mounted inverter and electrical component installation, battery integration and configuration, inverter output distribution, circuit separation, and 3-phase inverter synchronization.
The upgraded system was tested and commissioned, with recorded checks confirming PV operating voltage, autonomous charging, inverter AC output, utility charging, and battery voltage.
Scope of work
- Upgrade of the existing central solar system from 11.45 kWp to 25.61 kWp, including inverter power supply distribution and circuit separation
- Roof-mounted installation, wiring, and configuration of solar panels
- Wall-mounted installation of inverter sets, breakers, cable trunking paths, and busbar panels
- Battery connections and configuration
- 3-phase inverter synchronization, testing, and commissioning
Outcomes
- Expanded installed solar PV capacity from 11.45 kWp to 25.61 kWp
- Increased inverter capacity from 10 kVA to 30 kVA
- Increased battery storage from 15 kWh to 45 kWh
- Completed inverter distribution upgrade, circuit separation, testing, and commissioning of the upgraded system
Project details
Execution included rooftop installation, wiring, and configuration of solar panels, together with wall-mounted installation of inverter sets and supporting electrical accessories. GST also carried out inverter power output distribution and circuit separation works as part of the upgrade.
The system build included installation of breakers, surge protection devices, busbar panels, and battery integration. Two additional 15 kWh lithium battery cabinets were configured in parallel with the existing 15 kWh storage bank, bringing total storage capacity to 45 kWh.
The completed system was tested and commissioned. Recorded commissioning checks showed PV operating voltage at 90–100 V, successful PV autonomous charging, inverter AC output at 230 V, successful utility charging test, and battery voltage in the 51–53 V range.
This project demonstrates GST’s capability to upgrade an existing institutional solar asset rather than only execute a new installation. It shows practical experience in integrating additional generation, inverter capacity, and battery storage into an operational site.
The work also highlights GST’s ability to manage distribution improvements, protection components, and system synchronization while delivering a technically coherent upgrade. This is especially relevant for clients seeking phased expansion of existing solar infrastructure.
