Project Overview
This commercial solar solution for a farm in South Africa combines a 50kW shed rooftop PV design, a 50kW hybrid inverter and approximately 100kWh of lithium battery storage. The complete configuration is designed for daytime energy use and backup support for selected farm services.
Project Background
An equipment shed provides roof space for solar generation while keeping the covered area available for tractors and agricultural machinery. This dual use allows the farm to add generation capacity without allocating a separate ground-mounted solar area.
The load plan prioritizes lighting, security, communications and assessed auxiliary equipment. Pump motors, workshop tools and other high-demand machinery need separate evaluation before being connected to the backup circuit.
Project Challenges
The project design must coordinate available roof area, structural loading, wind exposure, PV string limits and cable routes. Mounting work also needs to preserve roof integrity and safe access for machinery and maintenance.
The electrical plan must address motor starting currents, daytime demand and the battery reserve for essential services. Battery and inverter equipment require protected installation space away from vehicle movement, dust and accidental impact.
WHC Power Solution
WHC Power’s configuration integrates rooftop PV, high-voltage lithium battery storage, a hybrid inverter, energy management and electrical protection. Available solar power can supply daytime farm loads and charge the battery when surplus generation is available.
BMS communication and energy management settings coordinate battery protection, reserve levels and discharge priorities. A dedicated essential-load circuit limits backup demand to the equipment included in the load assessment.
System Integration and EPC Support
WHC Power supports EPC partners with equipment selection, PV string configuration, battery and inverter compatibility and protection coordination. Installation planning covers mounting, earthing, isolation, surge protection, cable protection and maintenance access.
Commissioning should verify communications, protection settings, motor starting behavior and backup operation. Backup duration depends on actual demand, usable battery energy and reserve settings. Any generator connection requires its own electrical and control compatibility assessment.
System Configuration
Solar PV Design Capacity: 50kW equipment shed rooftop PV
Hybrid Inverter Rating: 50kW
Battery Configuration: Approximately 100kWh high-voltage lithium battery storage
Control: BMS communication and energy management
Application: Selected lighting, security, communications and assessed auxiliary loads
Operating Arrangement: Rooftop solar self-consumption with essential-load backup
Project Benefits
The design aims to increase daytime solar use and provide stored energy for essential farm services. At sites with backup generation, coordinated storage operation can reduce unnecessary generator runtime.
Using the shed roof preserves ground space and machinery storage. Integrated system planning helps the farm operator and EPC team address equipment compatibility, installation conditions and maintenance requirements before implementation.
