During the day, sunlight strikes the solar module, causing it to generate a specific range of DC voltage, convert the light energy into electrical energy, and transmit it to the intelligent controller. The electrical energy transmitted from the solar module is transmitted to the battery for storage after the intelligent controller's overcharge protection.
Working principle of the solar energy storage battery
During the day, the sunlight is irradiated on the solar module, causing the solar module to generate a certain range of DC voltage, converting the light energy into electrical energy, and then
transmitting it to the intelligent controller. After the overcharge protection of the intelligent controller, the electrical energy transmitted from the solar module is transmitted to the battery for storage;
Storage requires a storage battery, which is an electrochemical device that stores chemical energy and releases electrical energy when necessary.

Use and maintenance of solar energy storage battery
(1) Suitable working temperature: 15 ~ 20 ℃
(2) The method for connecting the solar battery is to connect the positive electrode and the positive electrode and the negative electrode and the negative electrode of the solar battery. 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.
(3) For the solar battery that is newly installed or charged for the first time after the renovation, it shall be charged for a long time. As the initial charge, it shall 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 power to fully charge the battery first. Excessive discharge charging should be strictly avoided. When AC power is used for normal charging, it is better to adopt the step-by-step charging method, that is, at the initial stage of charging, the constant current with a large current is used for uniform charging, and after charging to the uniform charging voltage and constant voltage for a certain time, the conventional constant voltage floating charging method is used.
(4) Keep the battery clean. The installed solar battery pole shall be coated with vaseline to prevent corrosion of the pole.
(5) Configure online monitoring and management technology for solar batteries, measure and analyze the internal resistance of solar batteries online, find out the defects of batteries in time, and maintain them in time.
(6) Prevent the solar battery from freezing and cracking in winter, avoid direct sunlight in summer, and put the solar battery in a cool, ventilated place.
