Product Description

Rooftop type resident photovoltaic systems have been widely used globally. However, due to loose module joints, poor contact, wire dampness, or insulation rupture, DC arc drawing can occur, potentially resulting in fire. On the DC side, as long as there is light, high voltage exists. This makes fire fighting extremely dangerous as firefighters cannot safely approach the scene.

The ERP Series Panel Level Firefighter Safety Switches provide a reliable rapid shutdown solution according to NEC 2017/2020 690.12 regulations for rooftop PV system safety.

✔ Meets NEC 2017/2020 690.12 regulations
✔ Comply with SUNSPEC protocol
✔ PLC communication control
✔ Match LVRT feature of the inverter
✔ Fire retardant V-0 / UV resistant materials
✔ Clasp design for simple installation

Frequently Asked Questions
FAQ Support
Q: When can I receive a quotation and detailed information after 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 units are IP66 rated and high-quality customized. For solar systems, quality should be compared before price for long-term safety.
Q: Can I get a sample before placing a regular order?
A: Yes, sample orders are the best way to verify quality and build trust.
Q: What is the delivery timeframe for urgent orders?
A: Sample orders typically take 3-7 days, while regular orders are promised within 15 days.
Q: What is the warranty period for the DC Isolator?
A: We offer a 2-5 year warranty depending on the specific product model.
Q: How do I choose the correct Rapid Shutdown model for my system?
A: It depends on your PV panel voltage. For example, if a panel is 39V and the switch is 1000V, one route can handle about 22 panels (1000/39/1.15). Ensure the current rating is higher than your string current.
