From August 8th to 10th, 2023, the "World Solar Photovoltaic and Energy Storage Industry Expo" will be held at the Guangzhou Canton Fair Exhibition Hall. Demuda cordially invites people from all walks of life to visit booth C427 in Zone B. The exhibition has a grand scale and is expected to have over 1500 exhibitors and an exhibition area of 100000 square meters, attracting more than 100000 professional visitors from over 100 countries. It is an important platform for the launch of new products, market expansion, and global layout in the photovoltaic industry. The exhibition focuses on promoting solar photovoltaic technology, showcasing products such as photovoltaic modules, inverters, energy storage systems, and will also hold technical forums. As a leading enterprise in the field of new energy controllers, Demuda will showcase its new solar products and explore the future development direction of the industry with customers.

The article focuses on the Demda solar-powered water pump inverter, introducing its core functions and advantages. This product is compatible with both AC and DC water pumps, supporting dual modes of photovoltaic direct drive and grid power complementation, and can intelligently track the maximum power point of photovoltaic systems. With built-in protections such as overload and undervoltage, it boasts a high protection rating and can adapt to complex outdoor environments. Suitable for applications like farmland irrigation and garden watering, the product helps reduce energy costs and promotes water conservation, energy efficiency, and sustainable development in related fields.

The article takes the DEMUDA lithium battery as a case study, elaborating on the core factors to consider when selecting energy storage batteries, such as compatibility, technology, scalability, quality, and after-sales service. This battery is compatible with major inverter brands, reducing procurement and maintenance costs. It employs Grade A lithium iron phosphate (LiFePO4) batteries and an intelligent battery management system (BMS), ensuring safety, efficiency, and a long lifespan. Supporting up to 15 parallel expansions (5-225kWh), it has undergone rigorous aging tests and offers a 10-year warranty with a 48-hour after-sales response. It meets diverse power needs across various scenarios, making it a secure and reliable energy storage solution

As the Northern Hemisphere nears summer, high temperatures increasingly affect the operational stability of inverters—core energy storage components—making internal cooling fan maintenance critical. These fans, which activate automatically above 50°C, use motors to drive blades for airflow and heat dissipation. Summer heat prolongs fan load and shortens lifespan, while dust buildup and humidity fluctuations may cause malfunctions. The article recommends targeted upkeep: choosing a well-ventilated, clean installation site, conducting weekly inspections and monthly cleanings, tightening screws, lubricating bearings, and replacing aged/damaged parts promptly. These steps ensure efficient fan operation, sustain inverter stability in high temperatures, and boost energy storage system performance and reliability.

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.
