The DEYE BOS-A-PDU-2 BMS controller is a modern intelligent control module designed to work with high-voltage lithium iron phosphate batteries of the BOS-A series (38.4 V, 200 Ah). The device ensures safe connection of the batteries to a solar inverter and stable operation of the entire power system even under demanding operating conditions.
Intelligent battery management
The system automatically controls charging and discharging, monitors the condition of every module and balances voltage and current. This extends battery service life and increases the efficiency of their use.
Comprehensive protection
The controller features a full set of protection functions: against overload, deep discharge, overvoltage, as well as against operation at critical temperatures. This guarantees the reliability and safe operation of the system.
Power supply flexibility
Two power supply options are available: from a built-in source or from an external one (8–36 V DC). This makes it easy to integrate the device into a wide range of power system configurations.
High-voltage support
The operating range of 235.2–919.8 V makes it possible to combine from 7 to 21 BOS-A battery modules into a single system, creating powerful and scalable solutions.
High performance
The rated charging current is 100 A with peak values of up to 160 A, which ensures fast recovery of battery capacity.
Stable operation in any conditions
The controller supports a wide temperature range:
- charging: from 0 °C to +55 °C
- discharging: from −20 °C to +55 °C
Robust design
A sturdy enclosure with IP20 protection rating, well-considered dimensions (610×610×135 mm) and a weight of 15.5 kg ensure durability and ease of installation.
Long service life
The device is designed for long-term operation and is covered by a manufacturer warranty of up to 10 years.
The DEYE BOS-A-PDU-2 is an efficient solution for managing high-voltage battery systems. It combines smart control, a high level of safety and configuration flexibility, which makes it a key element of modern solar power complexes.
