Maintenance
The inverter is designed to require minimal maintenance. However, to ensure optimal performance, it is important to follow these maintenance practices:
- General Cleaning: At least twice a year, and more frequently in dusty environments (weekly recommended), clean the cooling fans and air ducts to prevent dust accumulation. This will ensure proper ventilation and prevent overheating.
- Check Fault Codes: Regularly check the inverter’s display for any fault codes. If fault codes are present, they should be addressed immediately to ensure the system operates effectively.
- Lithium Battery Communication: Verify that communication with the Lithium battery is functioning correctly. This can be done through the inverter’s monitoring system or the battery management system (BMS).
- Weekly Cleaning: In environments with high dust accumulation or micro-ants, it is recommended to use micromesh filters. These filters can help keep dust, insects, and other particles out of the inverter’s internal components, preventing damage and ensuring proper airflow.
Appendix A: Residual Current Devices
If an external residual current device (RCD) is used, a device of type (A / AC, etc) should be employed, with a tripping current of 30mA or higher.
Use of RCDs
Residual current devices (RCDs): An RCD dedicated for an IES may be used to meet the mechanical cable protection requirements and isolation requirements of BS 7671 for the cable from the switchboard to the IES. If an RCD is used, the RCD shall:
- Disconnect all live conductors (including the actives and neutral).
- Be of the type specified in the inverter manufacturer’s instructions or as labelled on the inverter.
We recommend the use of an RCD on all circuits and sub circuits connected to the Sunsynk inverter. Residual current breaker with overcurrent protection (RCBO).
