What is an energy storage battery? An energy storage battery, as the name suggests, is a device that stores electricity. It is like a large-capacity ‘rechargeable battery’ that can be charged when electricity prices are low and discharged when prices are high or when there is a blackout to meet your daily electricity needs.

Energy storage is simply the storage of excess energy so that it can be released when needed. Just like when we charge our mobile phones, electricity is stored in a battery to be used when the battery is dead. However, the scale and application of energy storage is much broader than mobile phone batteries.

Lead-acid batteries have been powering our lives for over a century. These rechargeable batteries employ a simple yet efficient chemical reaction using lead plates and sulfuric acid electrolyte. They offer significant advantages such as high energy density, versatility, and low maintenance requirements. Despite advancements in battery technologies, lead-acid batteries continue to dominate applications in uninterruptible power supply (UPS), automotive industries, and off-grid solar systems.

A hundred years of inheritance and durability: the long history of lead-acid batteries The invention of lead-acid batteries dates back to 1859, when French physicist Gaston Planté invented them. After more than 160 years, lead-acid batteries are still one of the most widely used types of batteries in the world, which demonstrates their technological maturity and reliability.

In this era of rapid development, energy storage technology is undergoing a revolutionary change. Breakthroughs in new battery technologies are making our mobile phones, electric cars and home energy systems more efficient and convenient.

Simply put, green home energy storage is the process of storing electricity generated from renewable energy sources, such as solar energy, to be used when needed. It can help households reduce their dependence on the traditional grid and lower the cost of their electricity bills, while improving energy efficiency.

In recent years, the market demand for integrated PV modules + energy storage systems has been growing. According to MarketsandMarkets, the global market for integrated PV modules + energy storage systems will reach USD 10 billion in 2025.

The energy landscape is undergoing a transformation, and at the forefront of this shift stands a powerful duo: solar energy and energy storage. The coupling of these technologies, known as the solar + storage model, is rapidly gaining popularity, and for good reason.
