Firmware version of the battery
The firmware version of the BYD batteries can be accessed via the user interface of the battery (see manufacturer’s manual). Inverter firmware version
The firmware version of the inverter can be accessed via the user interface of the inverter.
| Type (Manufacturer) | Firmware version of battery: | Firmware version of inverter: |
| Battery-Box Premium HVM (11.0-22.1) (BYD Company Limited) | BMU ≥ 3.16 BMS ≥ 3.24 | ≥ 1.00.00.R |
| Battery-Box Premium HVS (5.1-12.8) (BYD Company Limited) | BMU ≥ 3.16 BMS ≥ 3.24 | ≥ 1.00.00.R |
Synchronizing the battery and hybrid inverter
All batteries mentioned supply a defined nominal current. Please pay attention to the battery manufacturer’s recommendation regarding the suitable dimensioning of the battery in order to achieve the nominal and overload currents of the systems stated in the datasheet with a Sunny Tripower Smart Energy. Only if the dimensioning of the battery size is synchronized (battery capacity, battery currents, number of battery modules if necessary), the full functionality and power incl. overload can be guaranteed for the PV storage system with the respective hybrid inverter in use.
