Solar Hybrid System Deployment for Agricultural Processing Plant in Southeast Asia

Solar Hybrid System Deployment for Agricultural Processing Plant in Southeast Asia

Timeframe: March 2023 - Present

Location: Rural Lampung Province, Sumatra, Indonesia (5°S latitude)

Climate: Equatorial (25°C-38°C), 95% avg. humidity, monsoon rainfall >3,000mm/year

Operational Challenges

1. Grid Instability:

   • Daily voltage fluctuations (300V-480V) damaging palm oil processing equipment

   • 8-12 hour weekly outages during monsoon season

2. Diesel Dependency:

   • 40% operational costs spent on diesel for 500kVA generators

3. Environmental Compliance:

    

    

    

   • Regional mandate requiring 30% renewable energy for export-oriented agribusinesses

   Deployed Solution: TP25KH Hybrid System Cluster

   System Configuration

   Component	Specification	Technical Alignment
   Inverters	4 × TP25KH	Nominal AC Output 25kW ×4 = 100kW capacity
   PV Array	180kW monocrystalline modules	*Max. PV Input 45kW/inverter* (within limit)
   Battery Bank	240kWh lithium-ion	*BAT Voltage Range 190-800V* (operating at 650V)
   Critical Loads	Sterilizers + Conveyors (88kW)	*Peak Output 37.5kVA/10s* handling motor surges

   Performance Validation

    

   Monsoon Resilience

   • Maintained IP66 protection during 290mm/24hr rainfall (Nov 2023)

   • DC Type II surge arresters prevented damage from 4 recorded lightning strikes

   Grid Synchronization

   • Stabilized voltage at 410V despite grid swings to 480V (*within 277-520V adjustable range*)

   • Achieved >0.99 power factor with variable crusher motor loads

   High-Yield Energy Harvest

    

    

   • 97.9% Eur. Efficiency despite constant 90%+ humidity

   • 3 MPPT channels per unit optimized yield across uneven rooftop arrays

    

   Quantifiable Outcomes

   Metric	Pre-Installation	Post-Installation
   Energy Reliability	73% uptime	99.6% uptime
   Operational Costs	$0.32/kWh	$0.08/kWh
   Carbon Emissions	288 tCO₂/month	89 tCO₂/month
   Equipment Damage	$18,000/year	$1,200/year
