Introduction
When a large construction project sought to power their office and manufacturing site whilst minimising their environmental impact and fuel costs, they faced a significant challenge. This case study explores how Callidus Engineering designed and implemented a cutting-edge containerised hybrid generator power system that dramatically reduced the project's reliance on conventional generators whilst maintaining reliable, continuous power supply.
Problem
The client faced several critical challenges:
- Heavy dependence on diesel generators, resulting in substantial carbon emissions and fuel costs
- High operational costs due to continuous fuel consumption
- Need for reliable, uninterrupted power supply
- Requirement for a solution that could power both office and manufacturing operations
- Need for remote monitoring and control capabilities
Previous solutions relied heavily on conventional generators, which were:
- Less Environmentally sustainable
- Cost-inefficient due to constant fuel consumption
- Maintenance-intensive
- Contributing significantly to the project's carbon footprint
Solution
Callidus Engineering developed a comprehensive containerised hybrid power system that integrated multiple renewable energy sources with smart control systems. The solution incorporated:
Power Generation and Storage:
- 200kW solar power array generating approximately 150,000kWh annually
- 288kWh battery storage system utilising 60 lithium batteries
- 135kVA of inverted power through 9 Victron Multiplus II units (15000VA each)
