Haier H0K6050P03-H HV Battery Control Box (BMS), 250–550 V DC, 50 A

The Haier H0K6050P03-H is the control module for the Haier HHS-1X5K/10K/15K/20K high-voltage battery storage system. You stack one to four battery modules between it and the mounting base, giving 5 to 20 kWh per system. The control module has a built-in battery management system (BMS) that collects data, monitors status and controls the system.

It works at 250-550 V DC with a maximum current of 50 A. It has a power button, a DC breaker, a Wi-Fi antenna and a display showing state of charge, system status, heating, network and battery module status. It has DC+ and DC- outputs, two parallel communication ports (COM0/COM1), an RS485/CAN port for the inverter, a LAN maintenance port and a protective earth point.

The control module comes with the base, wall-mounting brackets and fixing hardware. Up to three HHS systems can be connected in parallel. You can monitor and configure it with the PowerLite app over Bluetooth and Wi-Fi.
