(1) The working temperature is 15～20℃.
(2) The method of connecting the solar battery is as follows: connect the positive pole of the solar battery to the positive pole, and the negative pole to the negative pole. In this way, the power of the solar battery is doubled, and the voltage is the same as that of a solar battery. The poles of the solar battery must not be short-circuited (meeting).
(3) For the solar battery that is newly installed or charged for the first time after refurbishment, charge it for a long time. For the initial charge, it should be charged at a 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 for more than 8-16 hours in a sunny place or use AC power to fully charge the battery first. Over-discharge charging should be strictly avoided. When using AC power to charge normally, it is best to use the grading charging method, that is, in the early stage of charging, use a constant current with a large current to equalize, charge it to the equalizing voltage and maintain a constant voltage for a certain period of time, and then switch to the conventional constant voltage floating charging method.
(4) Keep the battery itself clean. Installed solar battery poles should be coated with Vaseline to prevent corrosion of the poles.
(5) Configure on-line monitoring and management technology for solar battery, conduct on-line measurement and analysis of internal resistance of solar battery, discover battery defects in time, and carry out 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 ventilated and cool place.
