Location and Compliance Section 3: Location and Compliance Location Note on DC Wiring and the NEC When installing the Generac PWRcell Inverter, consider the following: • The unit can be installed in indoor or outdoor locations. • The unit must be readily accessible. • The inverter installation location must meet the working space requirements in NEC Article 110.26. Some electricians or installers may be unfamiliar with DC wiring in a residential setting. Note the following: • NEC 690.
Location and Compliance Voltage and Frequency Trip Thresholds This unit or system is provided with fixed trip limits and shall not be aggregated above 30 kW on a single point of common connection. All Generac PWRcell Inverters are shipped from the factory in compliance with all UL1741 requirements, including IEEE1547.
Installing PWRcell Inverter Section 4: Installing PWRcell Inverter Mounting the Inverter 2. Verify fasteners are suitable for the mounting surface and can adequately secure the inverter to the wall. See Specifications for unit weight. WARNING Equipment damage. Mount inverter to a strong, stable surface. Never mount to drywall, plaster, or other non-structural wall treatments. Failure to mount inverter to a strong, stable surface could result in equipment or property damage. (000641) 1.

Electrical Connections Wiring Guidelines Grounding Bar Wiring DANGER WARNING Electrocution. Verify all system voltages are safe before wiring. Disconnect all AC and DC sources of power before touching terminals. Failure to ensure no dangerous voltages are present on conductors and terminals before wiring will result in death or serious injury. (000642) Equipment damage. Never connect REbus conductors to ground. Connecting REbus conductors to ground could result in equipment or property damage.
Electrical Connections DC Wiring AC Wiring WARNING Equipment damage. Connect only to REbus-compatible devices to the DC bus. Never connect to any other DC power source. Connecting to other DC power sources could result in equipment damage. (000598) WARNING Equipment damage. Do not connect PV string output directly to inverter. PV must be connected via Generac PWRcell PV Link. Connecting PV output directly to inverter could result in equipment or property damage.
Electrical Connections Protected Load WARNING Equipment damage. Never connect protected loads terminals to other sources of power, including any other inverter, the utility grid, or a generator. Doing so could result in equipment or property damage. (000648) WARNING Equipment damage. Never connect protected loads output from multiple inverters in parallel. Doing so could result in equipment or property damage.
Electrical Connections Connecting Ethernet IMPORTANT NOTE: Generac requires all PWRcell system components to be connected to the Internet and to maintain such connection throughout the warranty period. Internet connectivity is established via the PWRcell Inverter. By installing the PWRcell Inverter and connecting it to the Internet, Customer agrees that Generac may remotely monitor the use and condition of the system and update the system's software and firmware, as necessary, without further notice.
Electrical Connections Connecting CTs to the Inverter • See Figure 5-8. Connect CTs to the inverter using a RJ-45 connector and Category 5 (Cat 5) Ethernet cable. • CT input jack (H) is a double-stacked RJ-45 jack. NOTE: RJ-45 Breakout Adapter is included in the Generac PWRcell Kit. NOTE: If the RJ-45 Breakout Adapter is not available, the CT leads can be wired to a Cat 5 cable. Either the top or bottom jack may be used. Table 5-8.
