Just 40 km north of Adelaide, Lindham Piggery is a large-scale farming operation with continuous, high-energy demand. Central to its operation is a high-powered feed mill, which presents large and irregular peak loads. Historically, the mill was supplied by diesel generators, but the peaks regularly exceeded their stable operating range, resulting in inefficiencies, breakdown risks and escalating fuel costs.
On the other side of the property, the piggery relied on a single-phase grid connection, sufficient for light supply but incapable of running the mill or broader site. With fragmented power sources and growing energy demand, the business needed a complete site-wide solution: robust, expandable, and capable of replacing round-the-clock generator use.
The Engineering Challenge
The feed mill’s load profile was the critical design driver. Unlike steady agricultural
loads (lighting, pumps, ventilation), the mill introduced large, instantaneous demand spikes that conventional diesel generation struggled to handle. To achieve reliability, the site had been forced into inefficient generator operation, with high costs and poor load matching.
The engineering goal was clear:
Consolidate the piggery and feed mill into one power system.
Design an energy system that could manage extreme peak loads while maintaining stable supply.
Retain existing generators as emergency backup only, not primary supply.
Ensure future scalability as the operation continues to expand.
Containerised Off Grid Power System
MyEnergy designed and delivered a fully containerised, climate-controlled power station, built off-site for accuracy and quality control, then trucked to site for rapid installation.
Key Design Features:
Integrated Power Supply – Both the feed mill and piggery are now run under one consolidated system.
Peak Load Management – System engineered to handle mill spikes without relying on generators.
Containerised Housing – Fully insulated, ventilated, and climate-controlled to protect electronics and extend lifespan.
Serviceability – Clear layout with LED lighting, access for maintenance, and allowance for system expansion.
Backup Ready – Existing diesel generators retained for redundancy but now operate only in rare circumstances.
System Components:
Solar PV: 99.44 kW JA Solar Panels
Battery Storage: 256 kWh ZYC SIMPO lithium batteries
Charge Controllers: 4 × Victron SmartSolar MPPT RS 450/200-MC4 (DC Coupled)
AC Coupled Inverters: 2 × SMA Sunny Tripower X (25kW)
System Controller: Victron Ekrano GX
Mounting:
Installed with GAYK pile-driver to secure foundations through rocky ground
The new system has consolidated the entire site under one reliable supply. The feed mill’s peak loads are now absorbed by the inverter and battery system, avoiding generator trips or downtime. Diesel generators, once the primary source of power, now serve only as a backup safety layer, running rarely.
Benefits realised:
Diesel cost savings – fuel consumption reduced significantly.
Operational reliability – power stability across the site, including the feed mill.
Future scalability – modular design allows for simple expansion.
Reduced wear and maintenance – generators only run during backup scenarios.
Results: Reliable Power, Minimal Generator Use
By replacing continuous generator use with a containerised off grid power system, Lindham Piggery has achieved a robust and future-ready energy solution. The site now operates smoothly under one integrated system, with generators relegated to backup. This project demonstrates how engineered off grid systems can solve the challenges of peak industrial loads, delivering reliable power to large-scale agricultural operations where both diesel and grid connections fall short.
