Product Description

Rooftop type residential photovoltaic systems have been widely used globally. However, due to loose contacts of photovoltaic module joints, poor contact, wire dampness, insulation rupture, and other reasons, it is easy to cause DC arc drawing, resulting in fires. In addition, when a fire occurs, the DC side continues to generate electricity as long as there is light. High voltage persists, making fire fighting dangerous as firefighters cannot safely access the scene and must control the fire from a distance.

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 systems fire safety.

Frequently Asked Questions

How soon can I receive a quotation?

All enquiries will be replied to within 24 hours with detailed information.

What makes your DC Isolator different from cheaper alternatives?

Our products feature an IP66 degree of protection and are high-quality customized. For solar systems, comparing quality before price is the most reliable approach.

Can I request a sample before placing a full order?

Yes, we believe sample orders are the best way to build trust and verify product quality.

What is the expected delivery time?

Sample orders take 3~7 days, and regular production orders are typically fulfilled within 15 days.

What is the warranty period for the DC Isolator?

We offer a 2-5 year warranty depending on the specific product model.

How do I choose the correct Rapid Shutdown Switch model?

Calculation Example: If each PV Panel is 39V and the switch is rated at 1000V, each MPPT route can connect: 1000 / 39 / 1.15 = 22 pcs. For a 162-panel project, you would need roughly 8 sets of 2-pole switches (ERS-2) or 4 sets of 4-pole switches (ERS-4).
