Srezojevci Hybrid
Microgrid.
180 kW PV + 645 kWh
Comprehensive hybrid microgrid powering factories, medical clinics, hotels, and laboratories in a remote mountainous region of Serbia.
Powered only by
diesel — until now.
Srezojevci sits in a remote mountainous region of Serbia with no public grid access. Local factories, a medical clinic, hotels, and laboratories had long depended on diesel generators — incurring high fuel costs, unstable voltage, and frequent service interruptions.
The site also had to serve a diverse, high-inrush load profile — lathes, air compressors, and other motor-driven equipment — that demanded a system with strong overload and surge handling. Hua Power designed a fully off-grid solar–storage–diesel microgrid to replace diesel-only operation with clean, stable, cost-effective power.
From Diesel Dependency
to Clean Energy.
A comprehensive hybrid microgrid in the remote mountainous region of Srezojevci, Serbia. Previously dependent on diesel generators, the area now has clean, reliable power serving factories, medical clinics, hotels, and laboratories.
The system integrates 180kW PV, 645kWh battery storage, a 150kW off-grid inverter, and diesel backup. Primary loads total approximately 103kW, including hotel facilities, medical equipment, lighting, machine tools, air compressors, and motor equipment.

Backup
Diesel Generator
24/7 power through three coordinated modes.
Daytime
PV powers local loads and charges the 645 kWh battery bank.
Nighttime
Battery supplies continuous power to hotel, clinic, and production loads.
Backup
Diesel generator auto-starts only when needed; UPS-level switching protects critical loads.

mountainside.
Engineered for
Remote Reliability.
Solar–Storage–Diesel Coordination
Optimized control strategy: PV powers loads and charges the battery by day; battery carries the site overnight; diesel only fires as backup when needed.
UPS-Level Diesel Switching
Critical loads — medical equipment and production lines — ride through every PV/battery/diesel mode transition without interruption.
Industrial Off-Grid Inverter
150 kW industrial-grade inverter delivers the overload and surge headroom that lathes, air compressors, and other motor loads demand.
Multi-Level Protection & Monitoring
Battery management, inverter fault handling, and grid isolation safeguards with real-time dashboards for PV, battery, and load.
Remote Diagnostics
Cloud-connected diagnostics support remote fault detection, tuning, and predictive maintenance from Hua Power HQ.
On-Site Commissioning & Training
Hua Power engineers completed commissioning on-site and trained the local team to operate and maintain the system independently.
