Working principle of solar battery

During the day, the sunlight shines on the solar module, so that the solar cell module has a certain range of DC voltage to convert light energy into electric energy. Then it is transmitted to the intelligent controller. After the overcharge protection of the intelligent controller, the electric energy transmitted from the solar module is transmitted to the battery for storage. Storage requires storage battery, which is an electrochemical equipment that stores chemical energy and releases electric energy when necessary.

 

Use and maintenance of solar battery

 

Working temperature

The suitable temperature is 15 ~ 20 ℃.

The connection method of solar battery

Connect the positive pole to the positive pole and the negative pole to the negative pole of the solar battery. In this way, the power of the solar battery will double, and the voltage is the same as that of a solar battery. The two poles of solar battery must not be short circuited.

New battery charging

For the solar battery that is newly installed or renovated and charged for the first time, a long-term charging is the initial charging. It shall 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 in a sunny place for more than 8-16 hours, or use AC to fully charge the battery first. Over discharge charging shall be strictly prevented. When charging normally with AC, it is best to use graded charging. That is, at the initial stage of charging, the constant current charging with large current is used, and the conventional constant voltage floating charging method is used after charging to the uniform charging voltage and constant voltage for a period of time.

Keep the battery clean

The installed solar battery pole shall be coated with vaseline to prevent corrosion of the pole.

Configure online monitoring management technology

Conduct on-line measurement and analysis of internal resistance of solar battery, timely find the defects of battery and maintain it in time.

Deposit

Prevent the solar battery from frost cracking in winter and direct sunlight in summer. The solar battery should be placed in a ventilated and cold place.

 

The battery pack is used to store electric energy. The purpose of inverter is to convert DC into AC. When the solar cell module cannot work at night or in cloudy and rainy days, the battery pack supplies power to the load. The working mode of battery can be divided into two types: recycling and floating charge. It is often in the frequent charge and discharge working state, that is, it is recycled, and it is often in the charging state, which is floating charge, which can make up for the capacity loss of the battery caused by self discharge.

 

Characteristics of solar battery

 

Long life

Special process design and colloidal electrolyte ensure long-life battery.
