Off-grid power generation system of solar energy storage outdoor lamp pool installation points

Acceptance of 1) Battery shall promptly carry out inspection after the arrival of the goods, because of the appearance defect tend to influence the internal quality of the products. 2) According to the battery factory time, determine whether need to supplement the electricity, and for a terminal voltage test and capacity, internal resistance testing. If

to accept 1) Battery after the arrival of the goods, should be timely check appearance defects often affect the internal quality of products. 2) According to the battery factory time to determine whether need to supplement the power supply, and the examination of the terminal voltage, capacity and internal resistance testing. If the battery only after the arrival of the goods for inspection, according to the time of delivery of the battery in the case of does not charge storage, cold storage time will be more than 6 months ( Temperature > 33 ℃ for 3 months) , its technical performance indicators will surely fall further, can't even use. ？ Device battery installation quality directly affects the reliability of the operation, so the installation personnel must be trained or training to complete the battery installed. When handling the battery, not to mention pole, in order to avoid damage to the battery. Battery of seal leakage will cause the battery connector corrosion, directly affects the service life of batteries. Before installing the battery connector between the battery must be neatly arranged, shall be used for lubricant, or other chemicals, in order to avoid corrosion battery shell, shell burst and electrolyte leakage. Install battery technology conditions as follows: 1) Battery before installation, check the battery case, make sure that no physical damage. One end of the multimeter can be connected to the battery terminal, the other end can be connected to the appearance of wet wet suspects. If the voltage is zero volts, the shell will not damage. If the voltage is greater than zero volts, suggests that have acid. Need to be further examined. 2) Battery should be installed in a clean, cool, ventilated and dry place, and avoid direct sunlight. Stay away from the heater heat source or other radiation. Specific installation, should choose according to battery plate structure installation, shall not be tilted. Battery between ventilation measures should be taken to avoid the battery of combustible gas explode and burn. Because the battery in the process of charging and discharging will be fever, in order to ensure the battery good heat dissipation, the distance between the battery and battery generally greater than 50 mm. At the same time, the connection between the battery should meet the requirements of discharge current. For parallel connection, the battery impedance should be equal, battery, charging device and the connection between the load should not be used too thin or too long cable, so as to avoid in the process of current conduction the excessive voltage drop due to electricity and heat, and for the safe operation. 3) Before installing the battery, battery time interval between the production and installation. Battery open circuit voltage is measured, generally put into use in three months. If the battery to keep for a long time, the open circuit voltage is very low. At this point, the battery cannot be directly put into use. It should be in charge before use. After installation, should measure the battery voltage and DC gear digital instrument is used to measure the battery voltage. V is always greater than or equal to an integer. 12 ( V) ( N: relative to the number of battery 12 v battery series) ； If v is always less than Ntimes12 ( V) One by one, check the battery; If the two groups after battery series parallel, should in the connection of the two groups were measured before the storage battery voltage, the total v 1 is greater than or equal to Ntimes12 ( 5) ； V is a total of 2 is greater than or equal to the integer; 12 ( V) ( N: the number of battery series parallel branch) , two groups of battery terminal voltage error should be within the scope of the permit. 4) Battery could not use the old and new combination. Instead, should use the same set of all the new battery or all the old battery, in order to avoid imbalance, the status of the old and new batteries affect all battery service life and efficiency. For different capacity of the battery, and may not be in the same group in series. Otherwise, in the large current discharge or charge there are hidden dangers.
