9.4 Replacement of the electrical components
The electrical components inside the inverter must be replaced by the same

The model number can be acquired from the marking of the inverter or the component
itself. If otherwise, please contact Sungrow.
If the field work needs to replace the components with products from other
manufacturer and with different model number, a prior analysis and confirmation by
Sungrow is needed.
Failure to follow this procedure may lead to physical injury or death and void all
warranty from Sungrow.
