Maintenance
The inverter is low maintenance. However, it is important that at least twice a year (for dusty environments this may need to be carried out weekly) all the cooling fans and air ducts are cleaned and dust free.
Check if there are no fault codes and lithium battery communication is correct.
Weekly cleaning statement: suggest micromesh filters as an available option. Micro insects here are a real problem.
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).
