Don’t buy Sunsynk!

The equipment has broken in just over a week, Boxt is the supplier who have been horrific to deal with and I’m now in a dispute with them but as the inverter stopped working and now the battery, I’ve had the misfortune of trying to use the Sunsynk online chat. Save yourself the stress, they are terrible. Asking very basic questions that I’ve already clarified but the icing on the cake was asking if I’d tried switching it on. Save yourself the money, the stress and the hassle and buy a different technology.

Hi Andrew,
Sincere apologies that you are having these frustrations with your Sunysnk equipment.
I have read the two Live Chat transcripts between yourself and Rahul and Monisha.
It seems that your frustrations are mainly with your installer and unfortunately as you have stated in the chat that you currently don't have an internet provider that the dongle can connect to but that the installer had informed you that you could hotspot the dongle to your phone. This is correct but if the Installer didn't create the PLANT in the first place it is out of our control to be able to assist as we cannot see anything at all.
I understand that the LCD screen is blank and the inverter seems to be completely off but due to warranty purposes Sunsynk cannot be advising a customer on how to solve this issue.
We really need to speak to a fully qualified electrician or Installer, please could you ask them to call us on the following number: 0151 832 4300 so we can assist.
Kind regards

A fantastic service

I contacted Sunsynk through the app on the chat section .
I found it very easy to use , I think I only waited a minute or so for a reply from an advisor which I thought was fantastic by the way .
I think the advisor was very knowledgeable and I was given some advice which I shall follow up with my installer now . Overall a great experience. Thank you Sunsynk

Horrendous!!!!

Absolutely horrendous customer service is not something they even attempt completely ignored my queries and kept on sending me their manual. If I am supposed to read the manual then what are you here for. Others were not so bad but Anna Williams was rude and completely incompetent. There is no one there to complain to as well. Feels like a huge mistake going with Sunsynk you can't call anyone

Just added a third 8.8Kw inverter to the two existing inverters. The only problem I had was finding an older model that is compatible with the existing two. Once found and installed, the process of bringing the new inverter up to date was quick and invisible to the operation of the plant.

I didn't have to wait long, even though I was 4th in the queue. Contacted support about the charging issue, and they double-checked that I had set the timer wrong. Support reset the time setting for me, and everything is running smoothly now.

Don't buy the system through Renewafuel

Pros:
Nice app

Cons:
They use bad sales companies like Renewafuel who are just trying to sell you their pay monthly scheme and once you have paid in full and they have got your money no further contact.
First instillation and set up was wrong.
Second took ages to come out and put right.
But even then it was not set up correctly.
Poor customer service: did not return service request emails.
Renewafuel have no after sales service or training on how to set up system, system not set up right, we had to find some online videos on how best to set up the SunSynk system. Still not sure if it is set up correctly.
Arranged 3 call backs with Renewafuel to discuss optimising our system, they never called back.
Renewafuel have a bad CRM system as they installed our system and then were contacting us to arrange a call to sell a solar system.
Seems we cannot use the battery for our own use, only to sell energy back to grid.

Hi David,
Thank you for the feedback.
I have contacted Renewafuel who pointed out that you had also left a review on their Trustpilot page.
I have checked your Sunsynk System along with Renewafuel and cannot see any issues with the setup and we have done a firmware upgrade on the software.
When your installer contacts Sunsynk with any technical issues to do with you system they will be assessed immediately.
Many thanks
