Computer Monitor software with BMS

The built-in battery management system (BMS) can be connected to computer software for monitoring the battery’s status and other pack information. Additionally, users can define customized functions, and easily adjust BMS communication protocols for different inverters. Professional users have the ability to set various protection values, such as overcharge, over-discharge, and temperature thresholds. However, these advanced settings should only be adjusted by professional users with the necessary knowledge and expertise.


Lithium batteries are among the most commonly used energy storage units in today’s electronic devices. While they present distinct performance advantages in comparison to other battery chemistries, lithium batteries also present distinct safety concerns that must be addressed to ensure safety for end-product users.

All Coremax Solar energy storage batteries has already pass certifications like MSDS, UN38.3, IEC, CE. In additional, We can also provide other related test report accroding to the purchase order.

Lithium batteries are “dangous goods” GD goods. No matter shipping by air or sea freight. It require the test report and certifications. Please feel free to contact us.
