Frequently Asked Questions
❓ What problem does the GT-PCTC controller solve?
Compared with PV grid-tied inverters, small wind turbine grid-tied inverters in the market typically suffer from:
- Few professional small wind turbine grid-tied inverter factories.
- Wind turbine inverters are several times more expensive than standard PV inverters.
- Unstable quality and lack of after-sale service.
- Low efficiency and lack of proper grid connection certification.
❓ How does the protection system work?
The controller uses a dual-protection mechanism: PWM Constant Voltage + Three-phase Dump Load Brake.
- PWM Constant Voltage: Controls the wind turbine output so it does not exceed 120% of its rated power.
- Three-phase Dump Load System: If wind turbine speed exceeds PWM capacity, the system automatically and immediately engages the brake. The brake releases after 10–20 minutes, allowing the turbine to restart safely.
- During strong winds or grid disconnection, the controller maintains constant voltage output to protect the inverter.
❓ What automatic protection functions are built into the controller?
According to the system specifications, the automatic protection functions include:
- Over voltage protection
- Grid cut-off protection
- Regulated supply output
- Lightning surge arrester protection
❓ What safety mechanisms are available for emergencies or maintenance?
The controller features two manual safety systems:
- Emergency Stop Switch: Cuts off all power supply to the controller immediately and engages the three-phase dump load brake.
- Manual Brake Switch: Keeps the wind turbine braked continuously (via the three-phase dump load) for safe maintenance or inspection.
❓ What communication interfaces and remote monitoring options are supported?
The GT-PCTC controller supports the following communication options:
- Modbus Communication protocol for secondary development.
- RS485 interface for adjusting technical specifications.
- Optional USB, GPRS, WIFI, and Ethernet modules for remote monitoring via PC or mobile apps (compatible with both Android and iOS).
❓ What environmental conditions can the controller withstand?
The GT-PCTC series is built for extreme conditions:
- Operating Temperature: -30°C to 60°C.
- Relative Humidity: Less than 90% (non-condensing).
- Ingress Protection: IP20 for indoor installations and IP65 for outdoor setups.
