AI Review Summary
Based on recent customer reviews, Sunsynk receives widespread criticism for extremely poor after-sales service and lengthy repair turnaround times, with many customers waiting five to six weeks or longer without meaningful communication. Inverter failures within the warranty period are a recurring frustration, and customers report an inability to reach support via phone, email, or chat. The Sunsynk Connect app is also criticised for unreliable alerts and connectivity issues. Positive experiences exist but are rare, with a few customers praising friendly staff and successful repairs when eventually completed.

Terrible Service
Waiting more than a month for my Inverter to be repaired which is under warranty, just 8 months old. This is virtually a new product; it's not like it's EOL where you have to source parts so why do you say waiting for parts. You are more focused on selling than stocking up on spares

Customer feeback
How long are we supposed to wait for feedback on a unit sent in for quote / repairs? My unit was delivered on the 13 November 2025 and to date no feedback has been received. I have emailed requesting an update on the unit and asking how long it will still take to get an answer but no reply.

Sunsync connect garbage software
Sunsynk hardware products have not given any issues, the same cannot be said about the sunsynk connect software, absolute garbage. Dont expect ot to send you alerts , it does not, it does not even give the proper detail a lot of the time.

Poor sunsynk product and service.
I have bought a 8 kw sunsynk hybrid inverter 6 weeks ago. After 4 days it shut down with fault codes. The electrician came and remove it and took it back to the supplier he bought it from. After 6 weeks I still haven't received any feedback from sunsynk. Don't try to get information about your inverter on sunsynk customer service on app, it is better to communicate with a wall. They won't give you any information if you are not a registered supplier. I have bought this product, I have payed with my money for this defective product but they can't give me information about my inverter? Surely after 4 days sunsynk should have replaced the unit? The supplier contacted sunsynk and they only say it is on the bench and waiting for spares. Now we are sitting in the dark again but it is not sunsynk problem. I have been using the grid supply for 6 weeks now, who is going to refund me for use of eskom? Don't make the same mistake and waste your money on sunsynk just get a victron, at least they give their paying customers feedback and don't just ignore them.
