UL 8801:2020 free download Outline of Investigation for Photovoltaic-Powered Luminaire Systems
1 Scope
1.1 These requirements apply to low voltage luminaire systems whose electrical power is derived from photovoltaic modules. They include, at a minimum, a photovoltaic (PV) module, storage batteries, one or more co-located luminaires, and control electronics to manage the energy flow between these subassemblies. They are intended to be installed in accordance with NFPA 70, the National Electrical Code (NEC), Article 690 as a stand-alone system.
1.2 These requirements do not address the grid-interactive systems covered by NEC Article 690 or that include an inverter intended to supply line voltage luminaires or remote equipment.
1.3 These PV luminaire systems can include means to connect to and receive energy from the utility grid or similar supplemental supply source; see Annex B, Systems with Supplementary Power Connections.
1.4 PV luminaire systems without a supplemental supply source as noted in 1.3 are eligible for the lighting performance evaluation program in Annex A.
1.5 These requirements apply to fixed-in-place assemblies, to portable assemblies that are intended to be easily relocated, and to assemblies intended for periodic user disassembly and storage. 1.6 These assemblies are intended for outdoor, exposed installations within the nominal ambient temperature range of -40°C to +40°C, unless otherwise marked per clause 9.3. 1.7 These systems may include controls and devices to optimize system performance (such as sensors, positioning motors, and communication devices).
1.8 Some or all of the mechanical infrastructure to support or mount parts of the system are included. However, these requirements address only those features of these mechanical systems relative to risks of electric shock, fire, injury, and property damage. The supplemental requirements to fully evaluate the structural integrity of the mechanical infrastructure, including strength and stability of support poles under various environmental conditions such as wind or impact, and the assessment of soil or ground conditions necessary for system physical stability and reliability, are outside the scope of this document.
1.9 Except for components intended to connect to the utility for supplemental power in accordance with Annex B, these systems are expected to operate below 30 Vdc, the outdoor (wet location) class 2 voltage limits of the National Electrical Code (NEC). Other than if required by Annex B, and as permitted by NEC 411 (Low Voltage Lighting), these systems do not require grounding. However, they are not excluded from using earth ground as a reference.
1.10 These requirements do not consider the vibration and other environmental conditions that may occur for systems installed on watercraft, recreational vehicles, or other mobile platforms. 2 Components 2.1 A component of a system covered by this Outline shall:
a) Comply with the requirements for that component as specified in this Outline;
b) Be used in accordance with its rating(s) established for the intended conditions of use; and
c) Be used within its established use limitations or conditions of acceptability
