Use and maintenance of solar batteries

(1) The working temperature is 15~20 °C
(2) The method of solar battery connection is: connecting the positive electrode of the solar battery with the positive electrode, and the negative electrode with the negative electrode. In this way, the power of the solar battery will double, and the voltage will be the same as the voltage of a solar battery. The bipolar columns of the solar battery must not be short-circuited (met).
(3) For the first charge of the solar battery after new installation or refurbishment, a longer time charge, for the initial charge, should be charged according to the rated capacity of 1/10 of the current. Before installation, it is necessary to measure whether the battery is sufficient, if the power is insufficient, please charge the battery in a sunny place for more than 8-16 hours or use alternating current to make the battery sufficient, and over-discharge charging should be strictly avoided. When charging normally with alternating current, it is best to adopt a graded charging method, that is, use a large current of constant current to charge evenly in the early stage of charging, and use the conventional constant voltage floating charging method after charging to the average charging voltage and constant voltage for a certain period of time.
(4) Keep the battery itself clean. The installed solar battery pole should be coated with petroleum jelly to prevent corrosion of the pole column.
(5) Configure online monitoring and management technology for solar batteries, conduct online measurement and analysis of internal resistance of solar batteries, timely discover battery defects, and timely maintenance.
(6) To prevent solar batteries from freezing cracking in winter and avoid direct sunlight in summer, solar batteries should be placed in a ventilated and cold place.
