Where is the need for battery energy storage systems?

A lithium battery energy storage system (BESS) is a rechargeable battery that can store energy from different sources and release it when needed. BESS consists of one or more batteries and a hybrid solar inverter, BMS and EMS, which can be used to balance the grid, provide backup power and improve grid stability while monitoring the operating data of the battery. Currently, lithium battery energy storage systems are widely used in residential and industrial energy storage systems connected to solar power systems, outdoor farming or marine farming. Home energy storage is currently the most popular customer group, because it can reduce household electricity costs, and battery systems are gradually becoming lighter and more convenient.

Lithium iron phosphate batteries have a longer cycle life, but lower energy density. The charge and discharge efficiency is usually between 80-90%, and the battery life can reach 10,000 cycles.


Nalesa brand lithium battery energy storage system is a high-quality and cost-effective residential energy storage project. What we develop is a program that has high voltage and high storage power while being portable and using it as little as possible. Based on the concept of convenience, we integrate the inverter and BMS management system into a product without installation. For battery management, you can connect to your mobile phone to monitor the operation of the entire system at any time.
