Basic Descriptions
In recent years, renewable energy sources have gained significant momentum as the world moves towards a greener and more sustainable future. Solar energy, in particular, has emerged as one of the most promising renewable energy options. To make the most of solar energy, efficient battery storage systems are crucial. In this article, we will explore the advantages and features of a battery storage system with 6pcs 51.2v 100Ah lithium-ion phosphate batteries, integrated with solar energy storage BMS (Battery Management System) for any standard rack cabinet. Specifically, we will focus on Coremax's 30kWh solar energy storage bank system, which is suitable for home backup and small commercial use.
The Need for Efficient Solar Energy Storage
Solar energy is clean, renewable, and abundantly available. However, it poses a unique challenge: it is an intermittent energy source, as it relies on sunlight availability. To utilize solar energy effectively, we need to store excess energy produced during sunny hours for later use when the sun is not shining. This is where battery storage systems play a vital role.

Coremax, a leading manufacturer based in China, offers an innovative battery storage system that maximizes the potential of solar energy. This system is equipped with six 51.2v 100Ah lithium-ion phosphate batteries, providing a total capacity of 48v 600Ah. These batteries are known for their exceptional energy density, longer lifespan, and enhanced safety features.

We own a family solar business. I am I am curious what your pricing is on your 5.12 kW lithium iron phosphate battery. We are currently using these exact batteries through someone out of Utah. Is this something that you ship to the United States, if so how much would it cost for customs , and how long does it take for it to get to us? We do about 50 of these batteries on average per month with a Sol-Ark inverter. Also, what kind of software update what we need to make it work with Sol-Ark? I look forward to hearing from you. Thanks.
