16 × 5.12kWh = 81.92kWh nominal capacity
The Deye documentation specifies approximately 73.73kWh usable energy for an 81.92kWh system when using the specified 90% depth of discharge.
High-Voltage LiFePO4 Energy Storage
The BOS-G Pro uses Lithium Iron Phosphate (LiFePO4) battery chemistry, providing a robust platform for high-capacity energy storage.
Each BOS-G-Pack5.1 module is rated at:
-
5.12kWh
-
51.2V
-
100Ah
-
100A nominal charge/discharge current
-
125A peak current
-
90% DoD

The modular battery design allows the BOS-G Pro system to achieve high storage capacity while maintaining a structured and manageable battery architecture.
81.92kWh Nominal / 73.73kWh Usable Capacity
The BOS-G-PRO-80 provides:
| Battery Capacity | Energy |
|---|---|
| Nominal capacity | 81.92kWh |
| Usable energy at 90% DoD | 73.73kWh |
| Number of battery modules | 16 |
| Capacity per module | 5.12kWh |
This substantial storage capacity makes the BOS-G-PRO-80 suitable for applications where a large amount of stored solar energy is required throughout the day and during periods of grid interruption.
Long Cycle Life
The BOS-G Pro battery modules are specified for a cycle life of ≥6000 cycles to 70% end-of-life (EOL).
The system is designed for long-term energy storage applications and is backed by a 10-year service/warranty period specified in the Deye BOS-G Pro documentation.
Intelligent Battery Management
The BOS-G-PDU-2 provides the high-voltage control and battery management interface for the complete battery cluster.
The system monitors important battery parameters including:
-
Battery voltage
-
Battery current
-
State of charge (SOC)
-
Battery temperature
-
Battery-system status
-
Fault and alarm conditions
Protection functions include monitoring for conditions such as:
-
Over-voltage
-
Under-voltage
-
Over-current
-
Over-temperature
-
Isolation faults
This integrated battery management architecture helps protect the battery system and provides the connected inverter/PCS with important battery information.
High-Voltage Architecture
The BOS-G-PRO-80 uses 16 × 51.2V battery modules connected as a high-voltage battery system.
The Deye documentation specifies the 16-module configuration at:
-
Nominal voltage: 819.2V
-
Operating voltage: approximately 704–934.4V
-
Nominal energy: 81.92kWh
-
Usable energy: approximately 73.73kWh
This high-voltage architecture is particularly advantageous for larger energy-storage systems by providing substantial storage capacity within a relatively compact battery system.
Communication with the Inverter
The BOS-G Pro battery system communicates with compatible inverter/PCS equipment using:
-
CAN 2.0
-
RS485
The BOS-G-PDU-2 control box provides the communication interface between the battery system and inverter.
The Deye documentation specifies a default CAN communication speed of 500 bps and default RS485 communication speed of 9.6 kbps.
Suitable for Commercial & Industrial Applications
The Deye BOS-G-PRO-80 is designed for applications requiring substantial high-voltage energy storage.
Typical applications include:
-
Commercial solar energy storage
-
Industrial solar systems
-
Large backup-power systems
-
Solar self-consumption
-
Load shifting
-
Peak-load management
-
Renewable-energy storage
-
Farms
-
Schools
-
Banks
-
Supermarkets
-
Small factories
The BOS-G Pro architecture can also support multiple battery racks/clusters in parallel for larger installations.
Flexible & Scalable Energy Storage
Although the BOS-G-PRO-80 provides a substantial 81.92kWh of storage in one complete configuration, the BOS-G Pro platform is modular.
Deye specifies system configurations from 25.6kWh through 81.92kWh, using between 5 and 16 BOS-G-Pack5.1 battery modules.
This gives system designers flexibility when selecting the appropriate battery capacity for a solar or energy-storage installation.
