Highlights

Safe Battery Chemistry：KOK LFP ESS battery series are designed with LiFePO4 chemistry battery which has been widely recognized as one of the safest battery technologies. LiFePO4 chemistry features stable structures with low toxicity, well-defined performance, long-term stability. Automotive Standard Cell & Battery Structure Technology : KOK engineer & technician team bring our expertise at automotive battery R&D and manufacturing standards and technology to the design and structure of the ESS batteries.The cells inside are automotive-grade high quality cells, capable of high C-rate charge/discharge to support critical loads such as air condition, water pumps, EV charging, etc. And BMS is ESS- specific, with RS485, RS232, Canbus, SNM communication.
Easy Installation and Stackablity: KOK ESS batteries are modular-designed featuring easy installation and stackable up to 16 modules to meet higher energy consumption.
Wide Compatibility: KOK ESS batteries have commissioned for communication and compatibility with the major inverter and solar charger brands such as Victron, Huawei, Goodwe, Growatt, Voltronic, Kehua, Kstar, East, Luxpower, Megarevo, INVT, Ginlong, Sacolar, Sofar, etc. And the list is to be continued as our engineers are working on testing and commissioning with more inverter and charger brand.
Flexible Warranty Plans: KOK offers 3 warranty plans to cater to different customers’ needs-5 years basic, 10 years prolonged, 15 years super-long.
