1. First of all, check whether the battery indicator light of the controller is on. If not, check if the connection line between the controller and the battery falls off and the connection line is normal. Use the multimeter to check the battery voltage and the battery voltage is normal, instead of the controller.
Check if the controller load indicator is on, and use the multimeter to check the output voltage to see if there is a voltage output. If there is no voltage output, replace the controller. Check whether the input voltage of the LED driver is normal, check whether the fuse of the LED driver is intact, if the fuse is intact, use the multimeter to check whether the output voltage of the LED driver is normal, if it is normal, please change the LED lamp head, if it is not normal, please change the LED driver.
2. Does the spectrum provide spare parts? For vulnerable parts, the spectrum distributes spare parts in proportion to 3%?
3. Does the demand for photovoltaic modules face south? For users located in the northern hemisphere, it is best to face south for photovoltaic modules. In order to ensure that the component receives as much and as uniform radiation as possible, we have made the best inclination planning according to the region when planning the component bracket.
4. Are solar panels fragile? Compatible toughened glass panels search engine rankings are tested in simulated Arctic and Antarctic environments after hail tests.
