String Guardian (Voltage compensation device)
Essential equipment for maximizing power generation efficiency and safe power production at solar power plants.
Key features
- Reactive power compensation technology Maximizes generation efficiency by using (compensating) self-generated power that would otherwise be lost to shading, soiling, or faults to resolve power imbalance per circuit.
- High-efficiency by-pass circuit During normal operation the by-pass circuit prevents even the compensator from consuming power; when a fault occurs, by-pass ensures continued normal operation.
- Fewer components, fewer break points String-level compensation circuitry uses simple components to reduce break points and the risk of circuit failure and generation stoppage.
- Accurate fault detection Monitors in real time for risks such as circuit faults, short circuits, ground faults, and leakage, replacing the role of safety personnel who cannot be on standby 24/7.
- Rapid Shutdown Device (RSD) per circuit When an electrical hazard is detected, it automatically cuts power output from the modules to prevent fire and safety accidents.
Monitoring system
A monitoring system with the latest algorithms for stable solar power plant operation.
Key features
- Compatible with domestic inverters
- Per-string generation diagnosis and analysis
- Real-time monitoring of open circuit, short circuit, ground fault, leakage, fire, etc.
- Cumulative management of generation and weather data by period
- String-level data collection and analysis
- Collection of voltage, current, and CMV (common mode voltage) per string
- Hazard alert notification service
* This system is applied to power plants where Glen Tec voltage compensation devices are installed.
