Solar energy storage batteries (Lifepo4 lithium batteries) are the core energy storage unit of solar storage systems. They store the excess electricity generated by solar panels during the daytime and release power for loads at night or during power outages.

They can work perfectly with hybrid on&off-grid inverters. When sunshine is sufficient, surplus solar power will be stored in the battery bank; when there is no sunlight or grid failure, the battery supplies stable power to household or commercial equipment. These batteries are widely used for home rooftop solar storage, villas, commercial backup power, off-grid cabins, telecom base stations, agricultural irrigation and RV power systems.

We supply wall-mounted LiFePO4 energy storage batteries, the most popular type for residential solar projects. Compared with lead-acid batteries, LiFePO4 batteries feature longer cycle life, higher safety performance, higher energy density and lower self-discharge rate.

The lithium iron phosphate battery supports over 6000 cycles at 80% depth of discharge (DOD). Its working temperature ranges from 0℃ to 50℃ for charging, and -20℃ to 50℃ for discharging. Built-in intelligent BMS (Battery Management System) provides multi-protection functions including over-charge, over-discharge, over-current, short circuit and over-temperature protection.

It adopts wall-mounted design to save installation space. The battery supports parallel connection to expand total capacity flexibly. The communication ports RS485, CAN and RS232 are reserved to communicate smoothly with most mainstream hybrid inverters, including our VMIII & VMIV TWIN 4K/6K inverters.

China is the world’s leading manufacturing and exporting country for lithium iron phosphate energy storage batteries, holding more than 75% of the global production capacity of residential LiFePO4 batteries. Chinese solar storage batteries have been exported to over 190 countries and regions, covering Europe, Southeast Asia, South Asia, the Middle East, Africa and Latin America, supporting residential energy storage, commercial backup power and large-scale utility energy storage projects globally.

According to statistics from China Customs and China Energy Storage Alliance, China exported energy storage products with total power of 58.8GWh in 2024, and residential wall-mounted LiFePO4 batteries took up the fastest-growing segment. In the first half of 2026, the total export value of Chinese lithium energy storage batteries reached approximately 8.76 billion US dollars.

The European market is one of the biggest markets for home energy storage batteries. Many European families install wall-mounted batteries together with solar panels and hybrid inverters to maximize self-consumption of solar energy and benefit from net metering policy. Emerging markets show explosive growth. South Asian countries such as Pakistan, along with the Middle East, African and Latin American markets, have strong demand for household solar plus battery storage systems, especially in areas with frequent grid blackouts and unstable power supply.

Top Chinese lithium battery manufacturers own mature production technology. Our wall-mounted LiFePO4 energy storage batteries comply with international safety standards and have passed relative certifications. They can be matched with most global hybrid inverters and PV modules, adapting to various local solar storage projects.

Thanks to China’s complete new energy industrial chain, we can guarantee stable mass production, reliable delivery schedule and competitive product cost. We support FOB shipment from Qingdao, Tianjin and Ningbo ports. Every battery is packed with reinforced carton and foam cushioning to prevent damage during long sea transportation.

Driven by global energy price fluctuation and carbon neutrality goals, more and more families and enterprises choose solar energy storage systems to cut grid electricity cost and achieve power independence. Chinese LiFePO4 energy storage batteries keep providing safe and long-cycle energy storage solutions for worldwide renewable energy markets.
