The following are precautions for transporting solar power controllers:
1、 Packaging aspect
Choose appropriate packaging materials: A sturdy outer packaging box, such as a cardboard box or wooden crate, should be used. The controller itself can be wrapped with soft and elastic materials such as foam plastic and bubble pad to ensure that it will not be damaged due to collision during transportation. For example, if it is a small household solar power generation controller, use thick enough bubble pads to wrap it layer by layer, especially the wiring ports and other vulnerable parts of the controller, which should be protected with emphasis.
Sealed packaging: After packaging, ensure that the box is well sealed to prevent dust, moisture, etc. from entering. Tape can be used to seal the opening of the box, and for those with special protection requirements (such as transportation in high humidity environments), desiccants can be placed inside the box.
2、 Requirements for transportation environment
Temperature control: Solar power generation controllers are sensitive to temperature. Try to avoid transportation in high or low temperature environments. The generally suitable transportation temperature range is between -20 ℃ and 60 ℃. If transported in extreme temperature environments, it may damage the electronic components inside the controller. For example, during the high temperature period in summer, if the controller is transported on the top of an unshielded truck compartment, the surface temperature of the compartment may exceed its tolerance range, leading to a decrease in component performance or even damage.
Humidity control: To prevent the controller from getting damp. During transportation, avoid passing through areas with high humidity (such as open transportation in rainstorm weather) or contacting water sources. If the transportation passes through a humid environment or by sea, the packaging needs to be waterproofed, such as wrapping a layer of waterproof plastic film outside the box.
Avoid severe vibrations and collisions: During transportation, ensure that the controller is placed smoothly. If transported by vehicle, avoid sudden braking, sharp turns, and other situations to prevent the controller from being impacted due to inertia. For air transportation, it is necessary to ensure that the packaging can withstand the takeoff and landing of the aircraft as well as the bumps during flight. For example, when transporting on rugged mountain roads, the vibration amplitude of the vehicle is large, and it is necessary to add shock-absorbing materials such as sponge pads at the bottom of the box where the controller is placed.
3、 Regarding transportation labeling
Post warning signs: Clearly indicate “Fragile Items”, “Electronic Devices”, “Moisture proof”, “Upward” and other labels on the outside of the packaging. These markings can remind transportation personnel to correctly handle and place the controller, avoiding equipment damage due to improper operation. For example, the “up” symbol can prevent the controller from being placed upside down, as inversion may cause internal components to shift or wiring to become loose.
