A leading manufacturing facility in Southeast Asia required a high-reliability energy storage retrofit to solve severe grid instability, frequent voltage drops, and peak electrical demand surcharges impacting automated manufacturing lines.
Project Background & Customer Challenges
The manufacturing complex operated continuous stamping and SMT electronics assembly lines sensitive to brief grid dips. Unscheduled power interruptions caused significant product defects, tool recalibration downtime, and high utility peak-demand charges during daylight production hours.
WLUG Turnkey Engineering Solution
To solve the dual challenges of intermittent power loss and high peak electricity costs, the WLUG engineering team customized an industrial hybrid energy storage solution combining pure sine-wave three-phase inverters with modular rack-mounted LiFePO4 battery banks:
- Industrial Hybrid Inverter: Dual 6.2kW / 12kW hybrid inverters operating in parallel with high-efficiency MPPT controllers tracking rooftop solar inputs.
- Modular Battery Pack Bank: Three parallel WLUG 51.2V 200Ah (10.24kWh each) lithium iron phosphate packs, providing 30.72kWh scalable energy reserve with Grade-A prismatic cells.
- Smart BMS Control & Remote Telemetry: Industrial RS485/CAN communication linked to a centralized touchscreen and cloud telemetry portal for 24/7 cell voltage and temperature supervision.
Demonstrated Operational Value & ROI
Key Project Benefits:
- Zero Production Line Halts: Seamless <10ms transfer switch completely prevented power outage machine shutdowns.
- 42% Monthly Energy Cost Reduction: Storing low-cost solar electricity by day and discharging during afternoon peak tariff windows.
- Estimated 2.8-Year Payback: Equipment downtime losses prevented, coupled with stable electricity savings.
Following 6 months of continuous operation under high ambient humidity and temperature, the system has maintained a 100% reliability record with zero cell imbalances detected by the BMS.
