What caused the solar street light and solar wind street light light during the day

Solar street light Bai Tianliang lamp reason: 1, the solar panels during the day not by the controller to recharge the battery. Controller detection: controller turns red, said it was charging, the battery is full of red light flash, with pulse controller are small current charging.

solar street lamps Bai Tianliang up reason is:

1. Solar panels during the day, not by the controller to recharge the battery.

controller detection: the red light on the controller says it is charging, the red light flashing said the battery is full, the controller is in small current pulse charge.

solar panels: if solar panels connection is not very strong, can lead to charge is not normal, often voltage ( Voltage meter test) And normal open circuit voltage at 17. More than 5 v; But there is no current. This kind of phenomenon is improper panel wire connection ( There was a virtual welding or welding joint unstable) 。 This detection method can be at the back of the panels of black electrical cover opened, detecting data directly with voltmeter and ammeter. If the panels, aluminum foil is not directly detected currents, this means that the panel has a problem, need to change.

2. When the controller is connected, the positive electrode and negative electrode is upside down, lead to the controller component burn out.
