********** after-sales service

Bought a Sunsynk inverter for my son's house. Thought I was buying the best in the industry. Worked well for 3 weeks and then suddenly just died. Scrambled to get the electrician and other technicians out and they isolated the problem to the inverter. We returned the inverter to the supplier - Communica, and expected a prompt turnaround time as we are dealing with a major brand. Four weeks later we follow up with them and it's only then that Sunsynk provides a report - some or other IC is damaged and needs to be sourced from China. So we are now 6 weeks without an inverter and no reasonable time frame to a solution. This is really poor service from a major brand - would have expected a much better after sales service.
