Cannot login

As with other reviewers, I can no longer log into the app after entering username and password. The login button is greyed out.

Good Hardware, Terrible Software

This app is used to configure the Sunsynk Inverter. It uses different terms from settings in the web interface, which is almost as bad. This is one of the worst user interface designs I have ever had the misfortune to use. If you change the setting on one page it changes settings on other pages that you can’t see. Simply scheduling charge and discharge sessions requires a long, involved, and arcane process which may or may not work. Fortunately there is an independent app which is much better,
Come on Sunsynk, you launch a new product every week, but you can’t deliver a decent app?

Absolutely terrible do not recommend

App stopped working

The app worked well until a few days ago when I discovered I had been logged out of my account on both my iPhone and iPad. Now, when I try to login it accepts my username and password but after requesting the security code and entering it, the app screen reverts back to the default login requesting my username and password again. Retried on both devices numerous times without success. Website login works fine, so nothing wrong with my account. Tried deleting and reinstalling the app but still doesn’t allow me to log back in. Tried the Helpdesk but they were unable to help. Both iPhone and iPad are updated to latest Apple software version. Help!!!

For technicians, not and users

Absolutely hopeless for the end user. The thing that I use most is changing the charging periods and this is deeply buried in the app taking about five key strokes to get to it and then it’s presented in format taking up a huge unnecessary amount of space. They should outsource their app or create a completely separate simple app aimed at people who don’t have a degree in electrical engineering

Good hardware poor app

Love the inverter , works pretty well, just needs extra cooling. The app is bad when it comes to accessibility, fonts are very small and the most annoying is the sync. with the current data. You need to refresh the app few times to get actual readings. For the company like sunsynk they should do some improvements. For example I have Ecoflow system added to this and readings are constant live.

Needs more work

Hello,

I have two suggestions for your Sunsynk App development.

1) The off-peak and reduced rate for selective periods is becoming more sophisticated. I would like to select my Grid charging schedule over weekly periods by day. For example, Monday to Sunday 00:30 to 05:00 and also on a Sunday 11:00 to 16:00.

2) I would like to discharge my battery at 21:00 to 40% every day. Currently, I am doing this manually.

Best regards,

UK Customer

Needs a simple customer interface

Whilst it seems to work, it is the least user friendly app I’ve ever used. I know that there needs to be a lot of different settings available but it needs to have a really simple user friendly end user interface in front of the complexities. I want it to make it easy to manage my setup - when I want it to charge / discharge the battery, export to the grid or not. Has been designed by people who are not considering the end users needs.

Consistently unreliable

A well- installed system: with an app that simply doesn’t work!
It gets worse- the team that used to be on call to help, have now reversed themselves behind the app:which doesn’t work! So, you can’t contact them for help.
The worry is that your utilities provider doesn’t get the energy readings from your system… and no savings.
I’ve spent nearly £30k on my system. Think hard before you decide to join me😳

Energy flow direction do not show

It’s been 2 months I have been using the app. Initially it took time to
Understand the time but going on I can see so many gaps with the user interaction, usabily and comparability. App installed on the iPhone 16 pro max and the energy flow do not show on the app. Is this particularly to later models or the latest OS.

Log Out

The frequent need to log in is unnecessary and tedious even with a password manager. Please fix this.

Hardly ever works totally useless

Chinese support is useless

OK apart from every 1st of the month and when the clocks change, and the………

The app is pretty poor, txt size is not great, poor flexibility of charge/discharge rates, lacking in quality and reliability. Always seems down when the clocks change and the 1st of a month. Plus the random other offline periods. During 2024 I’d say circa 15 service interruptions.

Sunsynk Connect App is constantly timing out

The app times out and not updating per the recent app upgrades

What have the developers done?

More flakey than a 99

More flakey than a 99. Always down…
