How to get the attention of Sunsynk

Having gained the attention of customer services at Sunsynk and ownership of the communication and the problem Nikki made speedy progress in implementing an update to the firmware and restored my faith in dealing with Sunsynk having been trapped inside their chat line system.

Physical damaged repaired on warranty

My SunSynk inverter was damaged by a ham fisted installer ( coms wire yanked out bringing the socket and part of a printed circuit board with it). SunSynk repaired it, tested it and returned it to me within a week on the warranty! Excellent customer service and communication, very good product and company.

I’m quite upset with Sunsynk

I’m quite upset with Sunsynk. I have had my system for just under two years at a cost of £12k

The system broke down and after countless messages back and forth with Sunsynk I had to get an installer to come out to my house to diagnose the problem

I had to pay for an hours labor for a diagnostic which I understand needs paying

The installers then spoke with Sunsynk who said there was a fault with the system and the inverter needed to be sent back for repair. But now Sunsynk refuses to pay for the labor even after admitting there was a fault with their equipment

So I’m now £328.80 down on something they should have covered

So keep in mind if you spend thousands on a Sunsynk system the warranty isn’t what it’s made out to be and I do not recommend this company. They are very helpful when you want to buy something but don’t want to know when there’s a problem

Dear Chris,
Sincere apologies this has happened.
Please could you email my colleague joy.liddell@sunsynk.com with the name of your installer and Serial Number of your Inverter and she will make this a priority and investigate this issue.
Kind regards

I had a query about a new feature. Contacted Sunsynk by phone who suggested I try "Chat" and guided me how to do it (which I did). The chat support operator was most helpful. As they say - Sorted.

It is not often Tech support Teams gain praise but they should.

We have fitted Sunsynk inverters and batteries for the last five years and so have been there as Sunsynk has expanded and grown into the UK market. The Tech Support Team has always been responsive and helpful but as Sunsynk' s business has grown the service has not only kept pace with this growth but has evolved and improved. The service and team should be commended.

Another area of after sales service of considerable importance is warranty. Unfortunately things do break and when they do you want reassurance that the warranty repair or replacement is there. I have found the warranty support to be excellent.

Well done.
