The suitable working temperature is 15-20°C.
The method of connecting the solar battery is: 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 will be doubled, and the voltage will be the same as that of a solar battery. The two poles of the solar battery must not be short-circuited (meet).
For the solar battery that is newly installed or charged for the first time after renovation, it should be charged 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-charging should be strictly avoided. When charging normally with alternating current, it is best to adopt the hierarchical charging method, that is, use a constant current equalization charge with a large current at the initial stage of charging, and then switch to the conventional constant voltage floating charge method after charging to the equalization charging voltage and constant voltage for a certain period of time.
Keep the battery itself clean. The installed solar battery poles should be coated with Vaseline to prevent corrosion of the poles.
Equip the solar battery with online monitoring and management technology, conduct online measurement and analysis of the internal resistance of the solar battery, find out the defects of the battery in time, and perform maintenance in time.
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 cool place.
The above is the description of the service life of the solar battery and the precautions for maintenance. Generally, the working mode of the storage battery can be divided into two types: cycle use and float charge use. It is often in the state of frequent charge and discharge, that is, cycle use; it is often in the charge state and is used for float charge, which can make up for the capacity of the battery caused by self-discharge. loss.
