How to waterproof solar street light controller1

In recent days, continuous rainfall in most areas has made it easy to form water on the road. Someone may be troubled, so we will tell you how to solve the waterproof problem of solar street light controller!

　　 Solar street lamp controllers are mostly installed in lampshades and battery boxes, and generally do not enter water. However, in actual engineering cases, some of them are improperly installed or the circuit boards of some controllers are not treated with three-proof paint. Rain water flows into the solar street light controller along the external wiring of the controller terminal, causing a short circuit. Therefore, during construction, care should be taken to bend the internal connection wire of the controller terminal into a 'U' shape and fix it, and the connection wire exposed to the outside is also fixed to a 'U' shape, so that rainwater cannot enter and cause the controller to short-circuit. In addition, You can also apply waterproof glue on the inner and outer line interfaces to waterproof.
