(1) Suitable working temperature: 15 ~ 20 ℃
(2) The connection method of solar battery is: connect the positive pole and the positive pole, and the negative pole and the negative pole of solar battery. In this way, the power of the solar battery will be doubled, and the voltage is the same as that of a solar battery. The two poles of solar battery must not be short circuited (connected).
(3) For the solar battery that is newly installed or repaired and charged for the first time, it should be charged for a long time. For initial charging, it should be charged at the current of 1/10 of the rated capacity. 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 AC to fully charge the battery first. Excessive discharge and charging should be strictly avoided. When charging normally with AC, it is best to adopt the step-by-step charging method, that is, at the initial stage of charging, use the constant current of large current to charge evenly, and then use the conventional constant voltage floating charging method after charging to the uniform charging voltage and constant voltage for a certain period of time.
(4) Keep the battery clean. The installed solar battery pole should be coated with vaseline to prevent corrosion of the pole.
(5) Configure on-line monitoring and management technology for the solar battery, measure and analyze the internal resistance of the solar battery on-line, find the defects of the battery in time, and maintain it in time.
(6) Prevent the solar battery from freezing and cracking in winter, and avoid direct sunlight in summer. The solar battery should be placed in a ventilated and cold place.
