Actual usable capacity depends on inverter settings, battery protection limits, temperature and operating conditions.
🧠 Integrated Battery Management System
The built-in BMS helps monitor battery operation and provides protection against common electrical and operating risks, including:
- Overcharging
- Excessive discharge
- Overcurrent
- Short circuits
- High temperature
- Low temperature
- Cell-voltage imbalance
- Abnormal charging or discharging conditions
These protections help improve battery safety, performance and service life.
🔌 CAN & RS485 Communication
Compatible versions of the Yachu battery support CAN and RS485 communication, allowing the battery to exchange information with supported inverters.
This may include:
- State of charge
- Battery voltage
- Charging status
- Discharging status
- Protection conditions
- Operating information
Exact communication compatibility should be confirmed before installation.
🔗 Expandable Battery Storage
Compatible Yachu battery units may support parallel connections for installations that require more storage capacity.
For example:
- 1 battery: 5.12kWh
- 2 batteries: 10.24kWh
- 4 batteries: 20.48kWh
- 8 batteries: 40.96kWh
The maximum number of supported parallel batteries should be confirmed from the specific model datasheet.
