Page 3: Purpose Of This Guide
No responsibility is assumed by Renogy for any infringement of patents or other rights of third parties, which may result from use of the PV product. No license is granted by implication or otherwise under any patent or patent rights. -
Page 4: Safety Precaution Measures
Solar modules change light energy to direct-current electrical energy. They are designed for outdoor use. Modules may be ground mounted, mounted on roof, vehicles or boats. Proper design of support structures is the responsibility of the system designer and installer. Do not attempt to disassemble the module, and do not remove any attached nameplates or components. -
Page 5: Product Identification
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 Class II. Modules rated under this class should be used in systems operating at a voltage above 50 VDC or power above 240 W, where general contact access is anticipated. -
Page 6: Installation Considerations
Check applicable building codes and ensure that the structure can bear the module system load Ensure the supporting roof has fire resistant roof covering Renogy modules are listed as Class C under the UL790 Standard. Unpacking and Storing CAUTION Unpack module pallets carefully, making sure to follow all directions on the pallet. -
Page 7: Site Considerations
For detailed information on the best elevation tilt angle for the installation, refer to standard solar photovoltaic installation guides or a reputable solar installer or systems integrator. Site Considerations Renogy modules should be installed in locations that meet the following requirements: Operating Temperature within -40°F to 194°F Relative humidity within 45% to 95%... -
Page 8: Module Mounting
Installation Considerations All installation methods herein are only for reference and Renogy will not provide their own mounting components. Instead, the system installer is responsible for making sure installation is abided by all codes. Module mounting must use the pre-drilled mounting holes (Length * Width: 14mm x 9mm) in the frame. -
Page 9: Top Down Clamps
Top Down Clamps Clamps are an approved method of mounting for Renogy modules. A clamp holds two modules in a row. The centerline of the clamps must be in-line with the module mounting holes and installed according to code. -
Page 10: Grounding
Appropriate grounding consists of using an appropriately sized EGC or racking system that can be used for integrated grounding. Renogy panels implement a coated aluminum frame for corrosion resistance. The frame rails have pre-drilled holes marked with the grounding sign. -
Page 11: Module Dimensions
Module Dimensions The modules will be mounted using the mounting holes (on the short side of the aluminum frame), closest to the edges. 668mm [26.3 in] 35mm 140mm 509mm [1.38 in] 39mm 50mm [20.0in] [5.51 in] [1.54 in] [1.97 in] 50mm 35mm 70mm... - Page 12 RNG-270P 1002 mm [39.4 in] 35 mm [1.4 in] 6 mm 55 mm [0.24 in] [2.2 in] Grounding 14.5*6.5mm 35 mm [0.57*0.26 in] [1.4 in] 13 mm [0.5 in] 900 mm [35.4 in] 992 mm 1665 mm [39.1 in] [65.6 in] 958 mm [37.7 in] RNG-320D...

Page 13: Electrical Installation
Electrical Installation Electrical Specifications The electrical characteristics are within ±10 percent of the indicated values of Isc, Voc, and Pmax under Standard Test Conditions (STC Irradiance of 100mW/cm2, AM 1.5 spectrum, and a cell temperature of 25°C (77°F)) Under normal conditions, a photovoltaic module is likely to experience more current and/or voltage than its Standard Test Conditions rated output. -
Page 14: Cables And Wiring
Faulty connections can result in electrical shock so make sure to fasten all connections securely. Renogy modules can be installed in landscape or portrait orientation. Make sure that the proper distance between the panels and the surface allows for air circulation. -
Page 15: Bypass Diodes
Bypass Diodes The junction boxes used with the Renogy modules contain bypass diodes that are wired in parallel with the PV string cells. In the event the modules experience partial shading, the diodes are activated to bypass the current generated by the non-shaded cells, therefore limiting module heating and performance losses. -
Page 16: General Installation
All modules rated greater than 55 Watt have bypass diodes already integrated in the junction box. In the unlikely event of diode failure Renogy recommends a qualified service technician be employed to determine if diodes have failed and to make replacement. -
Page 17: Commission And Maintenance
Commission and Maintenance Renogy recommends that all work in commissioning and maintenance of a system must be performed by a qualified solar PV technician! Testing, Commissioning, and Troubleshooting Test all electrical and electronic components of your system before commissioning it. -
Page 18: Maintenance
5 percent, this indicates a bad electrical connection. 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. - Page 19 Replace a defective diode with a diode of the same type, and ensure that its polarity making is oriented the same way as the original diode. Finally, check the open-circuit voltage (Voc) of the module, as described previously, and replace both covers.
