Design for residential home or house owner

Coremax Technology is one of the most earlier manufacturer design and product the server rack style LiFePo4 batteries from Shenzhen China. The designed racked battery system is a perfect solution for both home and business solar inverter energy storage. We have been successfully serviced for many famous brand in USA and Australia market. We are looking for more possible brand to cooperate with Coremax. And provide our most reliable battery system for long term cooperation.

High quality LiFePo4 cells inside

Battery cell inside of any Solar energy storage battery system is the key point to make sure long life cycles and reliable. Coremax has been cooperated with major cell manufactures in China. Like BYD, CATL, EVE, GANFENG.. and so on. All cells are purchased directly from original cell manufactures and strictly tested before production. All cells with original barcode and SN no. Coremax bulk production will provide all cell data information for all inside cells. In this way, we can easy to track cells and make sure the fast response on any quality issue. As lithium batteries are dangerous, we deeply hope end users and also OEM brand customers deal with A grade brand new cells only. People’s safety and life is more important them any profit from business.

inside cells


When it comes to Solar energy storage battery packs. A professional BMS is absolutely important. Without a high quality and stable BMS, The battery pack life could be very short even you have great and A grade cells inside it. There are many ender users and DIY person ask BMS” like DAli, JBD. Please a professional solar energy storage system will never consider to use those brand. Only reason is because from above brands, you will never find a BMS design for ESS.


Coremax use professional BMS from ENJIE or PEICHENG which are consider as the best ESS BMS supplier at the moment. All BMS design based on residential storage and considers all basic strategy in terms of protocols for charging and discharge controls. Of cause, Coremax provide custom service based on different communication like RS485 or CANbus.

How does CMX battery rack storage system Work?

Chargeing and Discharge Information
Cycle LiFe test

In basic terms, sunlight is captured by your solar panels then converted into energy that you can use for your home. As that energy flows into your house, it is used by your appliances and any excess energy is stored in the 48v house battery Powerwall. Once the Power wall is fully charged, additional electricity your system generates on top of that is sent back to the grid. When the sun goes down and your solar panels are not producing energy, your Powerwall will provide electricity to power your home.


CMX lithium battery is not an online store. It required different system and custom features based on different solar energy storage systems. We need know more about your system config. CMX want to build long term win-win business relations with the battery distributors as well as photovoltaic installation contractors all over the world. Though not being an online store, purchasing server rack system from CMX is still very simple and easy!
