Test Environment
Unless otherwise specified, all tests in this specification are performed under the following conditions: The temperature is 25 ℃ +/- 2 ℃, the relative humidity is 25% ~ 85%, and the atmospheric pressure is 86kPa ~ 106kPa.
Data Archiving Requirements
The battery pack test data must be stored in the database and can be queried through the external code of the battery pack.
Battery Use
1. Before using the solar lithium battery, read the lithium battery specifications and charger specifications carefully to prevent damage to the battery and charger and causing danger.
2. When the battery is connected in series, if there is an oxide layer on the surface of the connection terminal, be sure to first brush the positive and negative terminals of the battery with a metal wire to a metallic luster to minimize the connection resistance.
3. As a backup power source, when used in conjunction with a load controller or device, the battery pack is equipped with a management system and cannot drive pure inductive loads (applied load or test load), otherwise the solar power system will be damaged.
4. The solar power system voltage exceeds 36V. In order to ensure personal safety, it is prohibited to directly touch the positive and negative terminals of the battery pack with your body.
Transport
Lithium batteries should be packed and transported in a state of half-charged 20% -50%. During transportation, they should be protected from severe vibration, shock or compression, and protected from sunlight and rain. They should be suitable for ordinary transportation such as cars, trains, ships, and aircraft
Storage
The solar lithium battery should be stored in a clean, dry and ventilated room at an ambient temperature of -5 to 35 ° C. Avoid contact with corrosive substances and keep away from fire and heat sources. Charge the battery every six months during storage. In the process of battery processing, the use of stock cells and battery delivery and storage should follow the "first in, first out" principle. The battery has a shelf life of 12 months from the date of storage. Products that exceed the deadline must be re-inspected in batches before being delivered to the orderer. If the batches are not qualified, they shall be submitted to the batch for inspection. If it is qualified, it will be disposed of by the purchaser.
1.Why liFePO4 batteries offer a better solar energy solution?
LifePO4 batteries have a life span more than 5-8 years.This dramatically reduces the need for battery changes. Lithium iron phosphate batteries operate with much lower resistance and consequently recharge at a faster rate.
2.What are LiFePO4 batteries used for?
Electronic car, back up system, solar energy system, Off-grid solar energy system, Wind energy system
3.Are LiFePO4 batteries safe?
The LiFePO4 batteries are the safest type of Lithium batteries as they will not overheat, and even if punctured they will not catch on fire. The cathode material in LiFePO4 batteries is not hazardous, and so poses no negative health hazards or environmental hazards.
4.How long do LiFePO4 batteries last?
LiFePO4 life expectancy is approximately 5-8 years. They are designed to last 3000 cycles, at which point the battery will still hold 75 to 80% of its energy capacity.
5.How to store LiFePO4 batteries?
Fully charge and balance the cells and then discharge to 50% of their rated capacity or less. Keep LiFePO4 batteries in a cool place 25℃ and they will be as well preserved from aging.
1.Our solar energy system USES car battery, the life of Lifepo4 battery is more than 3000 cycles.
2.At night, solar cells can power household appliances.
3.Easy to install and maintain
4.Can provide installation, maintenance and operation guidance throughout the process
