Battery installation

　　1. Since the battery leaves the factory with liquid charge, please move the bottom of the battery when handling it after opening the box. Please handle it gently.

　　2. It is strictly prohibited to open the battery valve, otherwise it will lead to poor battery sealing and affect the performance and life of the battery.

　　3. The same battery shall be of the same specification. It is not allowed to mix products made by different manufacturers.

　　4, the battery should be used in good ventilation conditions, not allowed to install the battery in a closed container or space, when the battery is buried in the ground to pay attention to waterproof and set vent, should avoid direct sunlight, away from hot objects.

　　5. During installation, please use insulating tools to avoid electric shock.

　　6, when the battery wiring, please connect the batteries to each other. Then, connect to the controller.

　　7. In order to obtain the expected service life, please choose the automatic current limiting and voltage stabilizing charging equipment, with voltage stabilizing accuracy of ± 1.5% for over voltage, under voltage and over current protection.

　　Inspection and maintenance

　　Check and repair the battery when it is running and keep a complete running record.

　　1. Check the appearance and voltage of the battery regularly.

　　2. Check the contents of the battery once a month.

　　Project content benchmarking

　　The voltmeter on the control panel has the value of floating charge voltage × the number of batteries floating charge voltage × the number of batteries

　　3. Check the contents of the battery for six months

　　Project content benchmarking

　　1. Total battery voltage in floating charge

　　1. Measure the total battery voltage with a 0.5 voltmeter

　　2. Read the voltmeter index value on the control panel

　　Total battery voltage (floating charge voltage × battery number)

　　1. Adjust the voltage when it deviates from the datum

　　2. Repair or replace if the error is greater than the allowable value

　　2. All single battery voltages

　　Measure the total battery voltage with a 0.5 voltmeter

　　Voltage deviation is less than or equal to plus or minus 0.1V/ monomer

　　When the voltage value of a battery exceeds the benchmark, it is observed that it has not returned to normal after 2 months. Please contact the company or replace it

　　3. Battery appearance

　　Check for damage and leakage

　　Find out the cause, if there is a crack in the shell, replace it

　　Presence of dust

　　Remove with a damp cloth

　　Check whether the connector terminal is loose

　　Tighten the bolts and nuts

　　Battery storage

　　1, the battery should be in a dry, ventilated, cool environment to park or store, strictly prohibited from damp, rain.

　　2, the battery in the process of placement, due to the loss of self-discharge capacity, the first discharge capacity will be lower than the rated capacity, generally after 2-3 charging and discharging cycles can reach its rated capacity.

　　3. When the battery is not in use for a long time, the battery shall be replenished regularly. The replenishment period is shown in the table below

　　Storage period replenishment system

　　No more than 2 months without power supply, direct use

　　Charge for 48h at 2.30v/monomer constant voltage for no more than 6 months (2d)

　　Charge for 96h at 2.30v/monomer constant voltage for no more than 12 months (4d)

　　Charge at 2.40v/monomer constant voltage for 120h(5d) within 24 months

　　After-sales service

　　1. Our company provides free selection service for users and assists in the design of the whole solar or wind energy system.

　　2. Within three months after receiving the goods, the company shall be responsible for replacing any objection to the products.

　　3. The company shall give a clear reply within 24 hours after receiving the user's service information and provide timely services.

　　4. According to users' requirements, on-site installation guidance and debugging can be conducted.

　　5. Provide technical training on the use and maintenance of valve-controlled sealed lead-acid batteries as required by customers.

　　6. Establish a complete user profile and a high-speed, fast and efficient service team, visit users regularly, even if the problems and difficulties in the process of using products are solved.

　　7. Widely adopted the use information and various requirements of customers for products, constantly improved and improved existing products and services and timely developed products to meet the special requirements of different users, with the purpose of continuously providing satisfactory products and services to customers.

　　Battery maintenance knowledge

　　1, battery cleaning please use as much as possible to wring dry wet cloth, please do not use dry cloth or duster, such as the use of dry cloth or duster will produce static electricity, sometimes become the cause of ignition, explosion.

　　2. Please replace the battery within the battery replacement time recorded in the operation manual or on the machine.

　　3, the battery to the end of life (is the initial discharge time of 50% of the possible use time significantly shortened. And will eventually cause internal short circuit, electrolyte depletion (internal resistance value increases) or positive plate grid corrosion and other battery failures. If continue to use in this state, then the maximum charge current will continue to flow, the battery will occur heat loss and the possibility of leakage, please change the battery before becoming this state.

　　4, please do not use the letter that water, gasoline, kerosene, volatile oil and other organic solvents and liquid cleaning agent, if the organic solvent and liquid cleaning agent contact the electric tank, sometimes become the crack of the electric tank, leakage reasons.

　　5, the battery terminal please use in a clean state, if the battery terminal dirty, with the body of the poor contact, sometimes become the power cut off, can not charge the reason.

　　Disposal of abnormal battery

　　Battery there is a strong substance dilute sulfuric acid, if battery leakage to the skin and clothes, please immediately clean with a lot of clean water, in addition, the liquid unfortunately splashed into the eyes, immediately clean with a lot of clean water, please seek medical advice as soon as possible. Dilute sulfuric acid enters the eye, which can cause blindness, and sticking to the skin can cause burns.
