is potentially hazardous. When disconnecting wires connected to a 1. Purpose of this Guide This guide contains information regarding the installation for solar modules. All instructions should be read and understood before attempting photovoltaic module that is exposed to sunlight, an electric arc may result. Such arcs may cause burns, may start fires and may otherwise create problems. Therefore, be extremely careful! to install.
2. Product Identification Renogy modules have been qualified for Application Class A. Modules qualified for safety through IEC 61140 and within this application class are considered to meet the requirements for Safety Before installing, obtain information about any requirements and preapprovals for the site, installation, and inspection from the relevant authorities. Check applicable building codes and ensure that the structure can bear the module system load Class II.
The module should be facing true south in northern latitudes and true for more details. Note that the holes in the center (blue) are for north in southern latitudes for best power production. grounding. For detailed information on the best elevation tilt angle for the Modules should be safely fixed to bear all expected loads, including installation, refer to standard solar photovoltaic installation guides or wind and snow loads. A minimum clearance of 0.25 in (6.
Note that the stainless steel washer is used between the grounding wire and the module frame. This is for avoiding corrosion due to dissimilar metals. The module frame must be properly grounded (refer to NEC clause 250). The grounding wire must be properly fastened to the module frame to assure good electrical contact. Use the recommended type, or an equivalent, connector for this wire. 4.2 Top Down Clamps Clamps are an approved method of mounting for Renogy modules.
an extra component such as a combiner box or an MC4 adaptor for parallel strings. Renogy recommends that only sunlight resistant cables be used with the minimum wire size being 4mm2 in diameter. Wiring PV Wire Type PV1-F1x4.
6. Commission and Maintenance when part of a module is shaded and the rest is exposed to the sun. These currents can cause the affected cells to get very hot and could even damage the module. To protect module from such high reverse currents Renogy recommends that all work in commissioning and maintenance of a system must be performed by a qualified solar PV technician! All modules rated greater than 55 Watt have bypass diode already 6.1 Testing, Commissioning, and integrated in the junction box.
In the case of not very low irradiance, if the voltage across the terminals differs from the rated value by more than 5 percent, this indicates a bad electrical connection. 6.2 Maintenance Renogy recommends the following maintenance in order to ensure optimum performance of the module: Clean the glass surface of the module as necessary. Always use water and a soft sponge or cloth for cleaning. A mild, non-abrasive cleaning agent can be used to remove stubborn dirt.
