Solar Energy Optimization

Designed to mitigate mismatch power loss from shading, aging to complex PV layout like multi-orientations etc.

 In addition to optimization, the HS4-A-O enables panel-level performance monitoring and rapid shutdown in compliance with NEC 2014, 2017, 2020.

PV Fire Safety

The HS4-A-F/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.

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.

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.
