When Every Second Counts: Powsaver’s Rapid Shutdown Systems Redefine Solar Safety！
Eliminate Electrocution Risks, Extinguish Fire Threats, Empower Emergency Responders！

The Hidden Danger: How Solar Arrays Become Deadly in Crises？
Imagine this scenario:A rooftop solar fire erupts during peak sun exposure. The 1,500V DC system remains live, a ticking time bomb.One misstep could electrocute crews or reignite flames. By the time they act, your home is reduced to ashes.
Powsaver eliminates this danger with industry-leading rapid shutdown technology across three critical safety layers: component-level protection, string-level isolation, and intelligent control. 

Component-Level Rapid Shutdown: PS-RSD-12
When safety demands millimeter-level precision, the PS-RSD-12 delivers:  
- Instant shutdown within NEC-required 30 seconds
- Dual-module isolation (21A max current) through physical contact separation  
- UL94-V0 flame resistance and IP68 waterproofing for worst-case scenarios  
- 25-year lifespan matching your PV modules' operational cycle  
Technical superiority meets installer convenience: SunSpec-compliant PLC communication eliminates complex wiring, while the compact 150g design installs faster than competitor units. 

 
String-Level Security: POWSAVER PS-FF+  
For commercial-scale protection, the PS-FF+ provides autonomous string monitoring:  

- 70°C auto-shutdown prevents thermal runaway before fires start  
- Built-in arc fault detection (optional) interrupts dangerous electrical discharges  
- 50A/1500V capacity handles utility-scale arrays without derating  
- IP65 metal housing withstands industrial environments  

The dual failsafe system combines temperature triggers with AC loss detection—when the grid fails, your safety system activates instantly. 

 
Centralized Command: PS-RSD-PC Control Box
Manage up to 20 strings through a single intelligent unit:  
300m PLC control range covers large rooftops and solar farms  
Fuse-protected MC4 connectors (20A rating) add secondary protection  
EN 60947-183 compliance meets strict EU safety directives  
-40°C to 70°C operation ensures reliability in extreme climates  

Unlike conventional combiner boxes, the PS-RSD-PC actively monitors each string while providing physical isolation—a critical advantage when milliseconds matter. 

 
Why Safety Can't Wait
Recent studies show:  
47% of solar-related fires originate from DC arc faults  
Firefighter injury rates increase 300% when rapid shutdown systems are absent  
Average liability claims exceed $250,000 per electrical incident  
Powsaver's triple-layer protection addresses these risks at their source:  
1. Component-level shutdown neutralizes panel-specific hazards  
2. String-level isolation contains faults before they propagate  
3. Centralized control provides system-wide visibility  

Compliance Without Compromise  
Our solutions don't just meet standards—they redefine them:  
- NEC 2017/2020 (690.12) rapid shutdown  
- UL1741, UL3741, and IEC/EN62109 certified  
- SunSpec interoperability for future-proof systems  

Solar energy shouldn't endanger lives.
With Powsaver's rapid shutdown ecosystem—PS-RSD-12 for precision protection, PS-FF+ for robust string control, and PS-RSD-PC for centralized management—you achieve:  
- Zero-voltage safety during emergencies  
- Uninterrupted compliance with evolving regulations  
- 25-year risk mitigation matching your asset lifespan  

Don't let your solar investment become a liability.
