solar street lamps factory on how to judge whether battery failures: testing data: battery: online voltage ( Battery and controller, panels and controller connection state) , the online voltage ( From the battery and controller status) , not let stand for 30 minutes after the voltage, online online let stand for 30 minutes after load discharge voltage. Panels ( At noon on a clear day) : open circuit voltage, charging current, short circuit current. Controller: to observe the indicator light, the input and output, whether be affected with damp be affected with damp and water, and if there is a burning phenomenon appearance. Battery: the battery clip off for the on-line state detection, if the battery voltage is within the scope of work ( 11. 00 v - 14. 50 v) , and other accessories are normal, the street light load can be take off, with panels at the controller directly to the battery charging more than 2 days, in fine weather, 2 days can be power battery charge. In the condition of the online measurement of battery voltage is very important, online state, the battery voltage is often due to connect the panels in charging status, voltage usually in 13. 00 v above, from the battery on the controller will be off after 30 minutes for the voltage of the accurate numerical online, load can be connected directly to battery, observe the battery voltage is stable, such as voltage drop in the slow and regular, prove that the battery is in good condition, if the voltage drop quickly, the battery in kui state electricity or other failure. The online state, if the battery voltage is lower than 10. 00 v, such as 5 v, 8 v, then battery has severely over discharge, and the scope of charging voltage identification in 10 of the controller. 00 v - 15. 00 between v, after the battery voltage is lower than 10 v, the controller can no longer on battery charging, then need to take special methods for processing or replace the battery. After the treatment, if using the above methods, street lamp still doesn't work, then the occurrence of failure has been a long time, at this time may have been caused by a lack of long-term rechargeable battery to causes such as loss of electricity and cause the sulfuric acid salinization phenomenon, so it is necessary to remove battery, on the professional repair.
