Introduction RSI 1 2 5 4 2 Rapid Shutdown switch SOLAR ON indicator 3 SOLAR OFF indicator 1 3 4 4 Initiates the PVRSS function; disconnects RTB and main contactor in combiner. Green LED indicator; illuminates when DC voltage is present and Rapid Shutdown switch is in the ON position. Red LED indicator. SOLAR OFF must be illuminated to confirm PV shutdown. This indicator tells responders that the Rapid Shutdown switch is in the OFF position to create a “safe” condition.
Introduction Functions Rapid Shutdown The rapid shutdown requirement is intended for firefighters or first responders. In an emergency, a responder may need to set the PV system in a “safe” (de-energized) state according to NEC 690.12. For this reason, the RSI is required to be mounted close to the main utility meter. The RSI must be easily visible. The RSI includes a Rapid Shutdown switch that initiates a disconnection of all elements of the PV system.
Introduction This page intentionally left blank.
Installation This section assumes the use of the combiner and the RSI. o The combiner box is a required part of all RSD-1 systems. All examples in OutBack literature show one or more combiners in use, including the Quick Start Guide. o The RSI is required for all RSD-1 systems utilizing the PVRSS function. Mounting Information The RSD-1 combiner box accommodates multiple mounting types. o It can be mounted horizontally, vertically, or at any intermediate angle.
Installation Surge Protector An optional surge protection device can be installed in the combiner. A knockout has been provided to accommodate this type of device. Figure 4 shows the underside of the combiner and the location of the knockout. NOTE: Any installed devices must be liquid-tight to sustain the combiner’s environmental rating. A. PV Conduit (2”) B. PV Cable Glands C. Surge Protector (½”) D.

Installation Optional Connections RSI The RSI has several sets of auxiliary terminals. Terminal J6 has a factory-installed jumper. J3, J4, and J5 do not. The terminals can be wired to the SkyBox, or possibly other devices, to send or receive status messages. AUX RSI COMMAND/STATUS OUTPUT Dry contacts which report RSI status. The J3 contacts must be connected to the RSD INPUT terminals on the SkyBox.
Troubleshooting LED Indicators (RSI) LED When Lit Notes SOLAR ON (green) DC voltage present in system. Rapid Shutdown switch ON. Despite the label, SOLAR ON does not indicate that the PV system is active. It will illuminate even if PV is completely disconnected or if an arc fault is present. The name indicates to responders that this control does not shut down other parts of the electrical system. It only affects PV-related devices. SOLAR OFF (red) System is in “safe” mode. Rapid Shutdown switch OFF.
Troubleshooting Table 1 Troubleshooting Symptom Possible Cause SOLAR OFF indicator and another indicator both lit. RSI miswired. Check all wiring between RSI and combiner. SOLAR ON indicator lit, but charge controller does not register PV input. Combiner disconnect switch turned off. Turn on combiner disconnect switch. Array wiring error or poor connection. Check all PV wiring to combiner. Use DVM to confirm voltage of each subarray at combiner input terminals. Fuses blown in combiner box.
