Description
The Suntree Under/Over Voltage Protector is a critical safeguard for solar energy systems, engineered to protect inverters, lithium/lead-acid batteries, and connected appliances from dangerous voltage spikes or drops. Designed for both DC and AC applications, it automatically isolates circuits when voltages deviate from preset safe ranges, ensuring longevity and stability in residential, commercial, and industrial solar installations.
Key Features & Benefits:
Adjustable Voltage Thresholds: User-configurable under-voltage (UV) and over-voltage (OV) trip points (e.g., 80V?300V DC or 150V?500V AC), customizable via rotary dials or digital interface.
Fast Response Time: Reacts within 1?2 seconds to abnormal voltage conditions, preventing equipment burnout or battery degradation.
Durable Construction: IP65-rated, flame-retardant (UL94 V-0) enclosure resistant to dust, moisture, and temperatures from -25?C to +70?C.
Auto-Recovery: Automatically reconnects circuits once voltage stabilizes within safe limits, minimizing downtime.
Real-Time Monitoring: LED indicators and optional remote communication (RS485/Modbus) for voltage status alerts and integration with solar monitoring systems.
Technical Specifications:
Voltage Range: DC: 12V?300V / AC: 100V?500V (configurable)
Current Rating: Up to 63A continuous (higher ratings available for industrial systems)
Response Time: <2 seconds (adjustable delay to avoid nuisance tripping) Mounting: DIN rail or panel-mounted Certifications: IEC 61008, T?V Rheinland, CE, RoHS Applications: Protecting solar inverters from grid overvoltage or generator surges. Safeguarding battery storage systems (LiFePO4, lead-acid) from over-discharge or overcharge. Stabilizing off-grid solar setups with fluctuating PV array output. Industrial solar farms requiring voltage regulation for sensitive machinery.
