From Fuel Dependency to Hybrid Efficiency: Zetatech Energy Storage System Powers Romania Project
Published: [October 17, 2025] | Category: Case Studies| Reading Time: 4 minutes
Introduction
In the pursuit of sustainable and cost-effective energy solutions, hybrid power systems are revolutionizing how remote and off-grid locations manage their electricity needs. This case study explores a successful hybrid energy installation in Romania that combines solar power, diesel generators, and advanced battery storage to create a reliable, efficient, and environmentally friendly energy ecosystem.
Project Overview: A Smart Hybrid Solution
Located in Romania, this innovative project represents a significant step forward in hybrid energy management. The installation seamlessly integrates three critical power sources:
System Components:
Solar Array: 50 kW photovoltaic system
Backup Generation: 80 kW diesel generator
Energy Storage: Zetatech 120 kWh battery energy storage system
Power Management: 50 kW Solis hybrid inverter
This combination creates a robust energy infrastructure capable of maintaining stable power supply while dramatically reducing fuel consumption and operational costs.
The Challenge: Overcoming Fuel Dependency
Many industrial and commercial facilities in remote or semi-urban areas face common energy challenges:
Traditional Pain Points:
Heavy reliance on diesel generators with volatile fuel costs
Inconsistent power quality affecting operations
High carbon emissions and environmental impact
Limited integration of renewable energy sources
Inefficient energy utilization during peak and off-peak hours
The Romania site needed a solution that could address these challenges while ensuring 24/7 power availability for critical operations.
Zetatech's Solution: Intelligent Hybrid Integration
120 kWh Energy Storage System Product Details
At the heart of this project lies Zetatech's advanced 120 kWh lithium-ion battery energy storage system (BESS). This system serves multiple critical functions:
Key Features:
Energy Buffering: Stores excess solar energy during peak production hours
Load Leveling: Smooths out power demand fluctuations
Peak Shaving: Reduces reliance on diesel during high-demand periods
Backup Power: Provides immediate power during grid or generator failures
Smart Charging: Optimizes charging cycles based on solar availability and load patterns
Seamless Multi-Source Integration
The 50 kW Solis hybrid inverter acts as the intelligent brain of the system, coordinating power flow between:
Solar Panels (Primary Source) - Clean, renewable energy during daylight hours
Battery Storage (Secondary Source) - Stored solar energy for evening/cloudy periods
Diesel Generator (Backup Source) - Only activated when renewable sources are insufficient
This intelligent hierarchy ensures maximum utilization of renewable energy while maintaining the diesel generator as a reliable backup rather than the primary power source.
Results: Measurable Benefits and Performance
Economic Impact
Lower Operational Costs: Significant reduction in monthly fuel expenses
Reduced Maintenance: Fewer diesel generator operating hours extend equipment lifespan
Predictable Energy Costs: Less exposure to volatile fuel price fluctuations
Environmental Benefits
Renewable Energy Integration: 70-75% of daily energy consumption from solar
Noise Pollution Reduction: Quieter operation with less diesel generator runtime
Alignment with EU Green Goals: Contributing to Romania's renewable energy targets
Operational Excellence
99.9% Power Availability: Seamless transitions between power sources
Improved Power Quality: Stable voltage and frequency for sensitive equipment
Real-Time Monitoring: Complete visibility into system performance
