User manual LG SOLAR

[. . . ] Module Installing structure (bent type) Module Installing structure (Stralght type) Use proper equipment, connectors, wires and buttresses for the installation of the module. failure to comply may result in product damage , product failure or bodily injury. Installation during rain, heavy wind or snowy day may result in bodily injury or death. Holes in the frame or glass of the module may decrease the strength of the frame or break the glass. [. . . ] €¢ Do not connect panels that have different electrical properties or physical configurations in the same system. €¢ Match the polarities of cables and terminals when making the connections; failure to do so may result in damage to the panel. €¢ The rating of the over-current device shall not exceed the maximum series fuse rating marked on the name plate. €¢ The panel contains factory installed bypass diodes located inside the junction box. €¢ When installing the system, it is recommended to install a lightning rod to protect the system. 3 Electrical Installation • The junction box should not be opened. €¢ Panels with a suspected electrical problem should be returned to LG Electronics for inspection and possible repair or replacement as per the warranty conditions provided by LG Electronics Parallel Connection • The solar modules may be combined in parallel to produce the desired current output. €¢ When modules are combined in parallel, the total current is equal to the sum of currents from each module. €¢ The voltage of each module connected in parallel should be the same. €¢ When connecting plural strings of modules in parallel every series string or solar module must be fused prior to combining with other strings. €¢ Abide with all applicable federal, state, and local codes for additional fusing requirements and limitations on the maximum number of solar modules in parallel. Fuse 20A : 1 string • Parallel configuration is not limited if proper measures are taken to block the reverse current flow, e. Fuses for the protection of the module and cables from over-current for prevention of unbalanced string voltage. €¢ A multiplying factor is required for increased output of the PV modules. Under normal conditions, a PV module is likely to experience conditions that produce more current and/or voltage than reported at standard test conditions. The requirements of the National Electrical Code (NEC) in Article 690 shall be followed to address these increased outputs. In installations not under the requirements of the NEC, the values of Isc and Voc marked on this PV module should be multiplied by a marked on this PV module should be multiplied by a factor of 125% when determining component voltage ratings, conductor ampacities, fuse sizes, and size of controls to the PV output. €¢ Depending on national directives, additional safety factors might be applicable for overcurrent protection. Electrical Connections • Shock hazard may occur near the solar modules electrical connections. €¢ Modules may be connected in series and/or parallel to achieve the desired electrical output as long as it is within the guidelines on the product specification sheet. €¢ Please use only the same type of modules in a combined source circuit. €¢ Do not disconnect the module under when it is operating. [. . . ] He/She further represents if he/she had any questions regarding this installation manual he/she would have contacted LG with any questions or concerns. By installing an LG Solar module, I discharge, and cove nant not to sue LG, its affiliated companies, successors, or assigns, its administrators, directors, agents, officers, volunteer and employees, other participants in any activity connected to installation, operation, or service of LG Solar Modules and if applicable from all liabilities claim Solar Modules, and if applicable, from all liabilities, claims, demands, losses, or damages on my account caused or alleged to be caused in whole or in part by the negligence of the LG its affiliated companies, successors, or assigns, its administrators, directors, agents, officers, volunteer and employees. Disposal • Please contact us, if you have any queries related to the disposal or recycling of solar modules from LG Electronics. Transporting and Storage • Do not loosen the banding, when the module is transported by truck, ship and etc. [. . . ]
