photovoltaic module that is exposed to sunlight, an electric arc may result. 1. Purpose of this Guide Such arcs may cause burns, may start fires and may otherwise create problems. Therefore, be extremely careful! This guide contains information regarding the installation for solar modules. All instructions should be read and understood before attempting Solar modules change light energy to direct-current electrical energy. They to install.
2. Product Identification Renogy modules have been qualified for Application Class A. Before installing, obtain information about any requirements and preapprovals for the site, installation, and inspection from the relevant authorities. Modules qualified for safety through IEC 61140 and within this application class are considered to meet the requirements for Safety 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.

These currents can cause the affected cells to get very hot and 6.1 Testing, Commissioning, and could even damage the module. To protect module from such high Troubleshooting reverse currents All modules rated greater than 55 Watt have bypass diode already integrated in the junction box. commissioning it.
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. Check the electrical and mechanical connections every six months to verify that they are clean, secure and undamaged. If any problem arises, have them investigated by a competent specialist.
