Electrical Installation

Grounding Connection

• All solar pv module frames and mounting brackets must be aligned in accordance with the corresponding National Electrical Code or local electrical code regulations

• You are advised to use a 4-14mm2 copper conductor (AWG 6-12) as the grounding conductor. The ground hole of the component is marked with “ ” .The ground wire must also be connected to the ground through a suitable ground electrode. All conductive connections must be securely connected.

• The diameter of the ground hole is 4.2mm on the aluminum alloy frame at the rear of the photovoltaic module. Connect the ground cable and related accessories to the aluminum alloy frame of the solar photovoltaic module and connect the ground cable to the ground. It is recommended to use M4 x 12mm ground bolt with M4 nut, star washer and flat washer. This ensures that the component is securely grounded. You can learn about the number, size and position of the grounding holes in detail on the Product drawings of Haitai. The torsional torque for grounding fixation is 4-8N ·m.

• In addition to using the ground hole for grounding, you can also use the following methods for grounding

• Use unused mounting holes for grounding

• Other special grounding devices No matter which grounding method is adopted, all grounding electrical contacts with the aluminum alloy frame of the PHOTOVOLTAIC module need to penetrate the anodized coating of the aluminum frame. When grounding a third-party grounding device, such as a dedicated grounding device, ensure that the device is reliable and professionally certified. When installing the device, comply with the manufacturer’s regulations.

Test Debugging and Troubleshooting

• The serial modules are connected to the test before the system. Use digital multimeter (recommended Fluke 170 series or digital multimeter which DC range can reach 1500V) to check open-circuit voltage of the series modules. The measurement value should be equal to the sum of the open-circuit voltage of a single module and you will find the rated voltage in the technical specification of the type module you are using.
• Low voltage troubleshooting. Identify the normal low voltage and fault low voltage. The normal low voltage mentioned here refers to the decrease of the
  open circuit voltage of the module caused by the temperature increase of the solar cell or the decrease of the irradiance. Fault Low voltage is usually caused by improper terminal connection or bypass diode damage.

Blocking Diode and Bypass Diode Troubleshooting

• Blocking diodes could prevent current from flowing from the battery to the module when the module is not generating current. If you do not use the charge controller, it is recommended to use blocking diodes. About charge controller, please consult a professional dealer.
• In the system, hot spot effect occurs when part of the module is blocked and other parts are exposed to the sunshine and thereby lead to overheat of the battery and damage the module. Using bypass diodes in the module protects the module from being affected by this excessive reverse current. All modules those rated power are more than 55 watts have a bypass diode integrated in the junction box.

On-grid Electrical System

• Try to use the same components in a photovoltaic power generation system, the number of modules in series （N）≤V（max）/[Voc(atSTC)].V (Max) is the maximum system voltage of the component, and Voc(atSTC) is the open-circuit voltage under the nominal state of the component.
• Several modules in series, and then form a PV array in parallel, which is particularly suitable for high voltage situations. If the modules are connected in series, the total voltage is equal to the sum of the voltages of the individual modules.
• In the case of using high current, you can put several PV modules in parallel, the total current is equal to the sum of the current of each module.
• The module can provide prefabricated connectors for system’s electrical connections. As for cable size, type and temperature and other parameters’ choice, please refer to the relevant rules.
• The cable cross-section surface and connector’s size must meet the maximum system short-circuit current, otherwise the cables and connectors will overheat because of excessive current and has the danger of burning!
• Protect yourself from electric shock when debugging or repairing the solar system. Wear protective gloves and insulated shoes and other protective equipment. Use special electrician tools for repairs.

Maintenance

• To ensure the best performance of the solar panels, Haitai New Energy provide the following maintenance measures.

• The solar panel should be cleaned in the morning or evening when the power is low or no power is processing.

• Cleaning the glass surface when necessary through clean water and soft objects. The neutral detergent should be used for cleaning while the acidic or alkaline or abrasive detergent is forbidden.

• In case of rainy weather, do not deliver the electricity if the inverter or other electrical equipment is power off. It is better to check and ensure that there is no problem in the lines before sending the electricity.

• When cleaning, the solar panel can not be washed with a high-pressure water gun for avoiding line leakage caused by excessive pressure in the connection place of the solar panel.

• Conduct a mechanical and electrical inspection for every six months and ensure that the surface is clean and the connection is reliable.
  If any other abnormal situation occurs, please consult factory or experienced engineer.

• Observe the maintenance instructions for all parts used in the system, such as bracket, charge controller, inverter, solar cell, etc.
