If the wind resistance coefficient is selected as 27m/s (equivalent to 10 typhoon), according to the non viscous fluid mechanics, the wind pressure of the battery pack is only 365Pa. Therefore, the component itself can withstand 27m/s wind speed without damage. Therefore, the key to consider in the design is the battery module bracket and the light pole connection. In the design of this set of street lamp system, the connection design of the module bracket and the lamp pole is fixed by the bolt rod. Wind-resistant design of street lamp poles.The main function of the solar charge controller is to protect the battery.
