This article introduces a typical configuration of a small-scale home solar power generation and energy storage system, including a 500W photovoltaic module, a 12V/50A solar charge controller, a lithium battery, and a 1000W inverter. It details the selection and key parameter settings of the controller and inverter. The article also explains the differences between off-grid and grid-connected systems, emphasizing that proper configuration can improve system performance and lifespan, and briefly introduces Demuda's products, advantages, and corporate capabilities.

On the anniversary of the victory of the Anti Japanese War, China showcased its military strength through a military parade, demonstrating its national defense technology capabilities. At the same time, China's industrial strength is reshaping the global landscape, becoming a leader in the field of new energy, with photovoltaic modules, lithium batteries, and other production capacity accounting for over 60% of the world's total. Military security ensures sovereignty, while industry and new energy ensure long-term stability. Together, they constitute China's comprehensive strength and contribute to the global transition to clean energy.

There are three types of lithium iron phosphate batteries: cylindrical, prismatic, and pouch (aluminum-plastic film) batteries. Cylindrical batteries, such as the standardized 18650 model, are widely used; prismatic batteries offer flexible capacity customization, safety, and durability, making them suitable for various applications; pouch batteries are lightweight, highly flexible, and perform well at low temperatures. Each type has its own technical characteristics, providing diverse options for fields such as home energy storage.

Against the global energy transition, rack-mounted home energy storage batteries—boasting modular design and high space utilization—are central to reshaping the home energy ecosystem. Their applications are diverse: coupling with photovoltaic systems to boost self-sufficiency, cutting costs via peak-valley pricing arbitrage, providing emergency backup power, and supporting microgrids and EV charging. Technically, they excel in energy density, cycle life, charge/discharge power, and intelligent BMS systems. In the global market, international brands and emerging Chinese brands compete, with Chinese brands offering notable cost-performance advantages. Driven by rapid market growth and global policy support, these batteries are shifting from optional to essential home energy equipment, holding immense development potential.

The Munich International Solar Technology Expo will be held from May 7-9, 2025, attracting 2737 companies from 57 countries and over 100000 visitors. At the exhibition, Chinese and foreign companies showcased new technologies such as photovoltaics and energy storage, such as GCLSI's BC technology module and CATL's 9MWh energy storage system. The industry is transitioning from "selling components" to "selling systems" and from "capacity competition" to "technology competition". In the global market, Europe, Asia, and the United States each have their own characteristics. Europe has a strong demand for distributed photovoltaics, China leads manufacturing and innovation in Asia, and policies drive development in the Americas. The exhibition showcases industry technological innovation and diversification trends.
