Statistics reveal that solar power system fires have caused significant damage in Vietnam, both in property loss and personal safety. Key causes include improper installation, substandard equipment, and environmental factors like lightning or extreme weather conditions.
1. Uncovering the Causes of Solar Power System Fires
Alena Energy will highlight simple yet crucial precautions that project owners can take to minimize fire risks in rooftop solar installations.
Globally, two main panel-to-inverter connection types are used:
- String Inverter: Uses series connections with high voltages (700-1,000VDC), increasing the risk of DC arc faults and fire hazards.
- Microinverter: Operates with parallel connections at lower voltages, significantly reducing fire risks but involves higher installation costs.
Understanding DC Arc Faults:
DC arcs form when high-voltage points come into close contact, generating extreme heat. For instance, at 350VDC, temperatures can exceed 300°C in just 30 seconds. A 1MW solar power system often has at least 3,600 connections, where poor contact can lead to DC arcs, potentially igniting surrounding materials.
Why Solar Panels Are Not the Culprits:
Fires typically start beneath the solar panels due to wiring or connection issues rather than the panels themselves. Solar panels are designed with fire-resistant materials that are difficult to ignite, even under intense heat. Specialized DC wires and metal cable trays also prevent fire spread, reducing overall risks.
2. Enphase IQ8P: A Comprehensive Safety Solution
- Rapid Shutdown Technology: This feature automatically disconnects solar panels from the electrical system upon detecting faults, minimizing fire and electric shock risks. Rapid Shutdown activates instantly, ensuring user safety.
- Compliance with International and Local Standards: Enphase IQ8P meets stringent safety standards, including UL 1741, IEEE 1547, and Vietnam’s fire safety regulations under Circular 3288/CP07-P4.
