1. Project Background

The customer is located in the tropical agricultural area of Penang, Malaysia. The farm requires 24-hour stable power supply, but faces two major pain points:

1. High electricity bills during the day

2. Grid instability affects equipment operation

2. Customer Demand

• 100% solar power supply + energy storage during the day, diesel engine supplementary power supply at night
• Need to be compatible with existing diesel generators to form a hybrid power supply system
• The energy storage system needs modular design to facilitate later capacity expansion
• Prioritize the use of peak-valley electricity price arbitrage to reduce diesel consumption

3. System Solution

4. System Core Advantages

(1). Efficient power generation design

• 180 595W modules form a 107.1kW array, with an average daily power generation of 428kWh (based on 4 hours of sunshine in Penang)
• The actual gain of the bifacial module is 8%, and the module operating temperature coefficient is -0.29%/℃, which is suitable for tropical climates.

(2). Smart energy scheduling

• Automatically start the diesel engine in off-grid mode (when SOC < 20%)
• Prioritize the use of energy storage power supply during peak hours (the local peak-valley electricity price difference is as high as 0.35 ringgit/kWh)

(3). Modular Expansion

• The battery system supports expansion in units of 2 units
• The inverter adopts master-slave mode and can be expanded to 20 units in parallel
