Safety Rules & General Information Section 1: Safety Rules & General Information Introduction Thank you for purchasing a Generac PWRcell® product. This owner’s manual includes full details on the use, operation, and maintenance of the PWRcell Battery. The companion document to this manual is the Generac PWRcell Battery Installation Manual.
Safety Rules & General Information General Hazards • Connecting the PWRcell system to the electric util- 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 operate or service this equipment and could result in death or serious injury. (000215a) WARNING Loss of life.
Safety Rules & General Information Electrical Hazards Battery Hazards WARNING DANGER Electrocution. Water contact with a power source, if not avoided, will result in death or serious injury. (000104) Explosion. Do not dispose of batteries in a fire. Batteries are explosive. Electrolyte solution can cause burns and blindness. If electrolyte contacts skin or eyes, flush with water and seek immediate medical attention. (000162) DANGER Electrocution.
Safety Rules & General Information Safety Precautions Symbols Warning symbols are used to warn of the conditions that may cause severe injury or damage to equipment. The following table describes the warning symbols used in the equipment's markings and within this document. This equipment contains high voltage which can cause electric shock resulting in severe injury. Ensure polarity of connections during assembly. Keep equipment away from open flame or ignition sources.

General Information Component Locations ON NOTE: Turn Battery Disconnect OFF whenever the system will be powered down and left inactive for an extended period of time to prevent battery discharge. OFF BATTERY DISCONNECT Battery Status LED A See Figure 2-4. The color and strobing interval of LED (B) communicates battery status. E B Table 2-1.
General Information . C F E G A D B B B H D 009893 Figure 2-5. Generac PWRcell System Example A B C D Solar Panels PV Link PWRcell Battery REbus E F G H PWRcell Inverter Grid Loads Protected Loads Communication All communication between REbus devices takes place over the REbus conductors using Power Line Carrier (PLC) communication. No additional communication wiring or equipment is required for communication between a PWRcell Inverter, PV array, and / or other REbus enabled batteries.
General Information Table 2-2. Battery State of Charge Setpoints Setpoint Behavior Shut off point where the battery stops discharging during a utility service interruption. When battery SoC reaches this value, the battery will go to sleep. The battery will charge again as soon as power is available on REbus. If the grid is not present and the system was islanding, the system will perform a Power Search every hour for four minutes. See Power Search. Min Absolute • Default value is 2%.
General Information Battery Settings Table 2-3. Battery Settings Setpoint Range Default Description PLM Channel 1 – 12 1 Channel for REbus communications. All devices in a system must use the same channel (except REbus Beacon). MinSocAbsl 0 – 20% 2 Minimum state of charge (SOC) absolute- this is the percentage of charge the battery will discharge to while the system is islanded.
General Information Island Mode In the event of a grid outage, the PWRcell Inverter enters Island Mode. While in Island Mode, the inverter disconnects from the utility grid and powers the building from the REbus nanogrid. In a typical solar-plus-storage configuration, this means all REbus-connected batteries will work together with the PV links to supply power to REbus. The inverter will pull power from REbus to provide AC power to protected loads.
General Information System Recovery During a Utility Grid Outage If during a utility service interruption, the PWRcell system stops powering backup loads, refer to Table 2-5. NOTE: Please read sections on Island Mode, Sleep Mode, and Power Search for complete understanding of system performance during a utility grid outage. Table 2-5. System Recovery Problem Possible Cause Solution During an extended grid outage the system turned off.
General Information System Blackstart By manually enabling the battery using the Battery Disconnect Switch, it is possible to perform what is called a Blackstart on the PWRcell system. IMPORTANT: Performing a Blackstart of the system will cancel a Shutdown initiated at the inverter and reenergize REbus DC wiring. NOTE: Blackstart battery voltage must be 13V or greater to power the system. See Service for more information. See Figure 2-8.
Maintenance Section 3: Maintenance General Upkeep • Keep the area around the PWRcell Battery neat and clean at all times. Ensure surrounding area is free of snow, sand, leaves, branches, pet hair, or other debris that could obstruct airflow in or out of the unit. Inspecting Vents See Figure 3-1. Verify intake vent (A) and exhaust vent (B) are clear at all times. • Do not store items on top of, under, leaning B against, or propped up where they might fall on the PWRcell Battery.
Maintenance Cleaning Outlet Vent Decommissioning Clean outlet vent (A) with dry cloth or shop vacuum. WARNING Environmental Hazard. Always recycle batteries at an official recycling center in accordance with all local laws and regulations. Failure to do so could result in environmental damage, death, or serious injury. (000228) WARNING A 011214 Figure 3-3. Cleaning Outlet Vent Service DANGER Electrocution. PWRcell Battery front cover should be removed by a qualified technician only.
