Important Safety Instructions Important Safety Instructions SAVE THESE INSTRUCTIONS General Safety NOTE Consult and follow local codes and other applicable laws concerning required permitting as well as installation & inspection requirements, rules, and regulations. Modules and PV systems should be installed by authorized and qualified personnel. Follow all safety precautions of all components used in the system.
A module's maximum reverse current is 30A. Using a blocking diode and maximum series overcurrent protective device in the combiner box are recommended for reverse current protection when more than four strings are connected in parallel. When used with a SolarEdge optimizer, it’s not needed because the optimizer has reverse current protection.

≥1.4m, 78 type PV module cable length ≥1.5m Regular Safety The application level of the SolarEdge Monocrystalline Bi-Facial module is Class Ⅱ, which can be used in systems operating at > 50 V DC or >240 W, where general contact access is anticipated.
Please refer to local laws and regulations before installing modules and abide by requirements on building fire protection. According to the corresponding certification standards, the fire rating of SolarEdge modules is Class C. The roof should be coated with a layer of fireproof materials with a suitable fire protection rating for roofing installation and make sure that the back sheet and the mounting surface are fully ventilated.
SolarEdge recommends that the tilt angle of module installation be no less than 10°. This allows rainfall to easily wash away any surface dust that accumulates on the module and reduces the required frequency of cleaning. It also helps to prevent water from pooling on the glass which otherwise over extended periods can create watermarks on the glass which may further affect module appearance and performance.
If the module's output power meets the acquired load under the period of the worst irradiation in the year, the modules should be able to meet the load for the whole year. If the SolarEdge modules are used in a grid-connected system, the tilt angle should be calculated based on the principle to maximize the yearly output power.
The modules and mounting system can be connected by bolts, clamps, or embedded systems. Installation shall follow the demonstration and suggestions below. If the installation mode is different, please consult with SolarEdge and obtain approval. Otherwise, modules could be damaged, and the quality warranty will be invalid.

DC electric parts. SolarEdge module's maximum system voltage is DC1000V/DC1500V---actually system voltage is designed based on the selected module and inverter model.
Bypass Diodes SolarEdge Monocrystalline Bi-Facial module junction boxes contain bypass diodes that are connected in parallel with the cell string. If a hot spot occurs, the diode will begin operating to stop the main current from flowing through the hot spot cells to prevent the module from becoming over-heated and to prevent performance loss.
Figure 6: Clamp grounding and bolt grounding methods The Third-Party Grounding Devices A third-party grounding device can be used for grounding SolarEdge modules, but such grounding must be proved to be reliable. The grounding device shall be operated as per stipulations provided by the manufacturer.
Operation and Maintenance To avoid the potential risk of electrical shock, do not attempt to clean any module that has exposed wires or damaged glass. Module Appearance Inspection Conduct a visual inspection of the modules and check for cosmetic defects, especially: Module glass cracks.
