PV Fire Safety
The HS4-A-F enables cost effective rapid shutdown functionality in a 1 module to 1 HS4 configuration. The HS4-A-F is both IEC and UL certified for global acceptance.
The HS4-A-F is UL 1741 PV Rapid Shutdown System (PVRSS) certified with hundreds of inverters to comply with NEC 2014, 2017, and 2020 rapid shutdown requirements. Many of the inverters with Sunspec communicate with the HS4-A-F over PLC, enabling plug and play installations.
HS4-A-F Photovoltaic Rapid Shutdown Switch
Features and Benefits
- Up to 800W per channel
- One module per HS4
- IEC and UL certified
- Meets US NEC690.12 rapid shutdown safety requirements
- UL PVRSS certified with the largest network of inverters
- 16-80V, up to 25A (per channel)
- MC4 (standard) connectors
- Snaps to module frame for easy mounting
- Does not require ground wire
- PLC communication
- 25-year product life design and 12 years service warranty
HS4-A-2F Photovoltaic Rapid Shutdown Switch
Features and Benefits
The HS4-A-2F enables cost effective rapid shutdown functionality in a 1 module to 1 HS4 configuration. The HS4-A-F is both IEC and UL certified for global acceptance.
It is UL PVRSS certified for connectivity with the largest network of inverters, many of which have a built in RSS transmitter. By connecting to two modules, the TS4-A-2F reduces labor time and enables 16% fewer connections on a 14 panel string compared to single channel MLPE.
- Up to 1600W (800W per channel)
- Single MLPE connects to 2 PV modules
- IEC and UL certified
- Meets US NEC690.12 rapid shutdown safety requirements
- UL PVRSS certified with the largest network of inverters
- 16-80V, up to 25A (per channel)
- MC4 (standard) connectors
- Snaps to module frame for easy mounting
- Does not require ground wire
- PLC communication
- 25-year product life design and 12 years service warranty
Module-level PV Monitoring
The HS4-A-M enables module-level monitoring sending alert notifications that are able to enable you to to proactively intervene early and maximize system uptime.
HS4-A-M Solar Communication Gateway
Features and Benefits
- Enables module-level monitoring
- View key performance information of each module
- Lower O&M costs
- Does not include rapid shutdown functionality
- 4G/WiFi wireless communication
PV TRANSMITTER HCPT1
Features and Benefits
- When receiving the transmitted signal of the incoming controller, the component string channel is opened and the inverter operates normally;
- When the transmit signal is not received, the MOSFET is quickly turned off, and the component string channel is also closed, so that the system’s high voltage is reduced to less than 30V within the 30s to ensure the safety of fire fighting and installation and maintenance personnel.
