Product Description

Rooftop type resident photovoltaic system has been widely used globally. However, due to loose contact of PV module joints, wire dampness, or insulation rupture, DC arc drawing can occur, potentially resulting in fire hazards. When fire accidents occur, the DC side continues to generate high voltage as long as light hits the components. This makes manual fire fighting dangerous, often requiring firefighters to control the fire from a distance.

Frequently Asked Questions
Q: When can I receive a quotation after sending an enquiry?
A: All enquiries will be replied to within 24 hours.
Q: What is the difference between your DC Isolator and cheaper alternatives?
A: Our DC Isolators are IP66 rated and manufactured to high-quality customized standards. For solar systems, quality should be prioritized over price to ensure long-term safety.
Q: Can I get a sample before placing a full order?
A: Of course! We believe sample orders are the best way to build trust and verify the quality of our components.
Q: What is the typical delivery timeframe for urgent orders?
A: Sample orders typically take 3-7 days. For regular production orders, we promise delivery within 15 days.
Q: How do I choose the correct model of Rapid Shutdown Switch?
A: It depends on your panel's open-circuit voltage and total quantity. For example, with 39V panels and a 1000V rated switch, one route can handle about 22 panels (1000/39/1.15). We offer 2-pole, 4-pole, and 8-pole versions to match your string configuration.
Q: What is the warranty period for the products?
A: We offer a 2-5 year warranty depending on the specific product model and application requirements.
