OPZV battery is also called tubular colloidal maintenance-free battery, with low self-discharge electrode. Such as opzv battery 2v 200ah 400ah 600ah 800ah 100ah 1200ah 1500ah 2000ah,,etc. Due to the use of high-quality materials, the monthly self-discharge rate is less than 1.5%; the use of colloidal electrolyte has large heat capacity and good heat resistance, which is suitable for use in harsh e...

In 2020, the global deployment of renewable energy will accelerate, and the newly added renewable energy installed capacity will be nearly 280 GW. It is expected that this growth rate will continue in the next two years and the increase in renewable energy is expected to account for 90% of the total increase in global electricity. The report pointed out that in 2019 and 2020, China's annual instal...

Half-cell Solar Panel Technology, Process and Development Trend   Technology A laser cutting method is used to cut the standard solar cell into two identical half cells along the direction perpendicular to the main grid line of the battery, and then weld them in series.   Since the voltage of the solar crystalline silicon cell has nothing to do with the area, and the power is p...

There are two types of household energy storage systems: one is off-grid energy storage, which is just needed, and is used in areas without power grids to meet the basic needs of the people; the other is grid-connected energy storage, which has developed rapidly in recent years. The investment method is mainly used in developed countries and regions with high electricity prices and large peak-to-v...

The winter storms that have struck many states across the United States have caused at least 33 deaths, millions of homes and businesses have continued to lose power, and water and natural gas supplies have also been greatly affected. Data shows that although the power outage caused by the winter storm has eased, as of the 17th local time, there were still more than 3.1 million households and busi...

Lithium iron phosphate battery energy storage system Lithium iron phosphate battery has a series of advantages such as safety and reliability, high working voltage, high energy density, long cycle times, long service life, and environmental protection. And can support the expansion of capacity, and can carry out large-scale electric energy storage after forming an energy storage system. The lithiu...

Newly purchased lithium batteries will be charged at the factory in advance, so customers can use them directly when they get the batteries. Then use up the remaining power and recharge it. After 2 to 4 times of normal use, the lithium battery activity can be fully activated. Here is a special reminder: Don’t mistake other unprofessional salespeople or rumors on the Internet. The new lithium batte...

As we all know, with the coming of US President Biden, the new energy industry will usher in a new wave of development. In the United States, Puerto Rico and other countries, solar energy storage systems will have greater demand. Energy storage photovoltaic systems can store the electricity of solar panels during the day in lithium batteries for use at night. The excess electricity can be sold to ...

Ho Chi Minh City, Vietnam plans to develop 1,000MWp solar rooftop power generation projects in the city’s industrial parks, export processing zones and high-tech parks by 2024. Currently, the installed capacity of such projects is 700 MWp. According to the data of the Vietnam Electric Power Company, so far, about 42,187 rooftop solar projects have been put into operation, with a total installed ca...
