1. The suitable working temperature is 15～20℃. 2. The connection method of the solar battery is: connect the positive electrode and the positive electrode of the solar battery, and the negative electrode and the negative electrode. In this way, the power of the solar battery will be doubled, and the voltage is the same as the voltage of a solar battery. The two poles of the solar battery must not be short-circuited (to meet each other). 3. For the solar battery that is newly installed or recharged for the first time, perform a longer charge, which is the initial charge and should be charged at a current of 1/10 of the rated capacity. Before installation, you must measure whether the battery is sufficient. If the power is insufficient, please charge the battery for more than 8-16 hours in a sunny place or use AC power to fully charge the battery first. Overdischarge charging should be strictly avoided. When charging normally with alternating current, it is best to use the hierarchical charging method, that is, use a larger current constant current equalizing charge at the initial stage of charging, and then switch to the conventional constant voltage floating charging method after charging to the equalizing voltage and constant voltage for a certain period of time. 12V12AH solar battery 4. Keep the battery clean. The installed solar battery pole should be coated with petroleum jelly to prevent corrosion of the pole. 5. Configure online monitoring and management technology for solar storage batteries, conduct online measurement and analysis of internal resistance of solar storage batteries, find defects in storage batteries in time, and perform maintenance in time. 6. Prevent the solar battery from freezing and cracking in winter, avoid direct sunlight in summer, and place the solar battery in a cool, ventilated place.
