Electrical installation

1. Electrical performance
   The nominal values of electrical performance parameters such as Sic, Vac and Pax of Galaxy Lightweight products have an error of ±3% from those under standard test conditions. Standard test conditions for Galaxy Lightweight products: irradiance 1000 W/m2, cell temperature 25°C, atmospheric mass AM 1.5. When Galaxy Lightweight products are connected in series, the total voltage is the sum of voltage of every single Galaxy Lightweight products in the string, and when Galaxy Lightweight products are connected in parallel, the final current is the sum of the current of every string of Galaxy Lightweight products, as shown in Figure 6-1. Galaxy Lightweight products of different electrical performance models should not be connected in one string.
   The maximum number of single strings of Galaxy Lightweight products that can be connected in series must be calculated in accordance with the requirements of local electrical requirements and regulations. and the value of its open- circuit voltage at the lowest expected local temperature conditions must not exceed the maximum system voltage value specified for Galaxy Lightweight products (maximum system voltage for the products is DC1000V/DC1500V – the actual system voltage is designed according to the selection of the product models and inverters) and other values required for DC electrical components.
   The open circuit voltage correction factor can be calculated with following formula: CVoc=1-βVoc×(25-T) where T is the minimum ambient temperature expected at the system installation location and β(%/°C) is the temperature coefficient of the open circuit voltage of selected Galaxy Lightweight product(refer to the corresponding Galaxy Lightweight product parameter table). If a reverse current exceeding the maximum fuse current of the Galaxy Lightweight product may pass through the Galaxy* Lightweight product, an overcurrent protection device of the same size must be used to protect the product. If the number of parallel connections is more than or equal to 2 strings, there must be an overcurrent protection device on each string of the products, as shown in the figure 6-1.

2. Cable and Connecting Wires
   Galaxy Lightweight products shall be connected by using IP67 rated junction boxes, which shall provide safe protection for the conductors and their corresponding connections, and accessible protection for non-insulated live parts. The junction box consists of a connected cable and IP67 rated connectors to facilitate series connection between Galaxy Lightweight products. A single product has two separate wires connected to two separate junction boxes, one positive and one negative. Two Galaxy Lightweight products can be connected in series by inserting the positive connector into the socket of the negative connector of the adjacent product.
   Use dedicated solar cables and appropriate connectors (wires should be encased in age-resistant conduit or, if exposed to air, should be age-resistant themselves) and ensure that the cables are electrically and mechanically sound, in accordance with local fire, building and electrical codes. Installers should only use single-core solar cables, 2.5-16mm2 (5-14 AWG), 90°C rated, with appropriate insulation to withstand the maximum possible system open circuit voltage (as approved by EN 50618).
   Appropriate wire sizes need to be selected to minimize voltage drop. All wiring and electrical connections comply with the requirements of the appropriate National Electrical Code or standard. Avoid mechanical damage to the cable or Galaxy lightweight products when the cable is secured to the bracket. Do not press the cable with force. The cable shall be secured to the bracket by specially designed aging resistant cable ties and wire clips. Although the cable is resistant to aging and water, it should be protected from direct sunlight and rain. The minimum bending radius of the cable should be 43mm.

3. Connector
   Please keep the connector dry and clean, and make sure that the nut of the connector is tightened before connecting. Do not connect the connector when it is wet, dirty or in other unfavorable condition. If the connector is not connected properly to the other polarity, the connector is not waterproof. It is necessary to connect or take appropriate measures to avoid the infiltration of water vapor and dust as soon as possible after the module is mechanically installed to the roof. Avoid having connectors being exposed to direct sunlight and immersed in water. Avoid having connectors falling on the ground or on the roof. Incorrect connections may produce arcing and electric shock. Make sure all electrical connections are secure. Make sure that all connectors with locking are fully connected. It is not recommended that connectors of different models be connected and used together.

4. Bypass Diode
   The cell strings within a solar module are protected by bypass diodes in parallel and encapsulated in a junction box. When a hot spot phenomenon occurs locally in a module, the diode will activate so that string current no longer flows from the hot spot cells, thus limiting module heating and performance loss. Note that the bypass diode is not an overcurrent protection device. Contact the installer or system maintainer when a diode failure is detected or suspected. Do not attempt to open the module’s junction  box by yourself.
