Hybrid Power System for 24/7 Poultry Farm in Malaysia
Project Overview
In response to a fully off-grid poultry farm requiring reliable 24/7 power, FFD POWER deployed a 210kW/466kWh BESS in Malaysia as part of a standalone hybrid system integrating PV + battery + genset. The system bridges the gap between a zero-grid-access site and the farm’s need for continuous electricity by prioritizing PV generation, using the BESS to cover non-solar hours, and automatically starting the diesel generator when PV is unavailable and battery SOC reaches a defined threshold. This hierarchy minimizes diesel runtime while maintaining stable 24/7 power for critical farm operations.
Project Background
The customer operates a poultry farm in Malaysia with no access to the utility grid. The farm requires 24/7 electricity to maintain ventilation, lighting, feeding and watering systems, and other critical loads. To ensure continuous supply while controlling fuel costs, the site adopted a hybrid architecture combining PV generation, battery storage, and a diesel generator. The project required an EMS-controlled hierarchy that prioritizes PV first, uses the BESS as the primary non-solar supply, and starts the generator only when PV is unavailable and battery energy is low.
Project Challenge
- Fully Off-Grid 24/7 Operation: The farm requires uninterrupted power without any utility grid connection.
- Hybrid Source Coordination: PV, BESS, and generator dispatch must be coordinated to ensure stability and minimize diesel runtime.
- Automatic Genset Start Logic: The system must start the generator reliably when PV is insufficient and battery SOC reaches the defined threshold.
FFD POWER Solution
FFD POWER delivered a 210kW/466kWh BESS integrated with a hybrid inverter in a standalone PV–BESS–genset system for a poultry farm in Malaysia. The control logic prioritizes PV generation to supply farm loads and charge the battery. When PV is unavailable, the BESS discharges to supply the loads and maintain stable voltage and frequency through the PCS. When PV is unavailable and battery SOC falls below the configured threshold, the system automatically starts the diesel generator to supply the loads and recharge the BESS, ensuring 24/7 continuity with reduced fuel consumption compared with a genset-only approach.
System Specifications
- PV installed : On-site PV plant
- BESS POWER : 210 KW
- BESS Capacity : 466 KWH
- Product used : Galaxy233L all-in-one Cabinet * 2 + EMS
- Architecture: Standalone PV–BESS–Genset Hybrid System with PV Priority and Automatic Genset Start
Operational Logic: PV Priority, BESS First, Genset as Last Resort
The hybrid controller coordinates PV, battery, and generator operation to ensure stable off-grid supply with minimized fuel consumption:
- PV Priority Supply: PV supplies the farm loads first and charges the BESS when excess PV is available
- BESS as Primary Backup: When PV is insufficient or unavailable, the hybrid inverter discharges the BESS to maintain stable voltage and frequency for continuous operation.
- Automatic Genset Start & Recharge: When PV is unavailable and BESS SOC reaches the configured low threshold, the system starts the diesel generator to supply loads and recharge the battery, then stops the generator when conditions allow.
