Introduction and Safety Section 1: Introduction and Safety Introduction Thank you for purchasing Generac SnapRS™. SnapRS devices are solid-state switches designed to safely interrupt a circuit of solar photovoltaic (PV) modules in the event of a rapid shutdown command from a Generac PWRcell™ Inverter. This manual provides instructions for installing SnapRS. Commissioning instructions are provided in the Generac PV Link™ Installation Manual.
Introduction and Safety General Hazards • Connecting Generac PWRcell to the electric utility DANGER Automatic start-up. Disconnect utility power and render unit inoperable before working on unit. Failure to do so will result in death or serious injury. (000191) WARNING Risk of injury. Do not operate or service this machine if not fully alert. Fatigue can impair the ability to service this equipment and could result in death or serious injury. (000215) WARNING Loss of life.
Introduction and Safety Electrical Hazards Safety Shutdown DANGER DANGER Electrocution. Water contact with a power source, if not avoided, will result in death or serious injury. (000104) DANGER Electrocution. In the event of electrical accident, immediately shut power OFF. Use non-conductive implements to free victim from live conductor. Apply first aid and get medical help.

General Information PVRSS Information Component Locations PVRSS requirements have evolved over time and are defined by the National Electrical Code (NEC) in conjunction with UL 1741. The 2017 and 2020 NEC added to the PVRSS requirement by mandating the need to reduce voltages of controlled conductors to less than 80 VDC within the array. NEC Article 690.12(C) contains all of the requirements for the type and location of the PVRSS initiation device.
Installation and Enabling Instructions Section 3: Installation and Enabling Instructions Installing SnapRS Devices To install SnapRS devices: 1. See Figure 3-1. Connect one SnapRS device (C) to the negative (-) whip of each PV module (D). 2. Connect the modules in series with the SnapRS devices installed inline between modules by connecting the positive lead of each module to the SnapRS device already installed on the negative lead of the next PV module in the series. 3.
Installation and Enabling Instructions Enabling Generac SnapRS Devices Generac SnapRS devices are controlled by Generac PV Link. See the Generac PV Link Installation Manual for information on commissioning Generac SnapRS devices.
Troubleshooting Section 4: Troubleshooting CAUTION Equipment damage. Never open a Generac SnapRS device. Generac SnapRS devices are factory-sealed and contain no field-servicable parts. Opening a Generac SnapRS device could result in equipment damage. (000667) There are no functional tests that can be performed on SnapRS devices in the field. However, some simple digital multimeter (DMM) checks can confirm the general health of a SnapRS device.
