Providing solar power and battery storage to 3 farm buildings 

Challenge

• Power was required to build two new residential and one commercial building planned for a farm

• The lines company quoted the farmer a very high amount to provide mains power to the new development. 

• The cost of connection to the grid made the project unfeasible

• An alternative and omre economic power supply was a necessity

Solution

Installation of a Micro-Grid Power System, powered by an Off-grid solar PV array and energy storage system 

• Supply of a ground mounted, central PV array

• Installation of an Outback Power 12 kW peak power inverter system to supply all 3 buildings with electricity

• Supply of a Sonnenschein battery bank

• Provision of a Cat 22kVA diesel generator as a back-up solution

Outcome

• Significant improvements in the overall construction budget for the project, making it possible to start construction of the buildings

• Abundant power available throughout the day from PV modules and at night from the battery storage system

• No electricity bills

• Highly reliable power supply
