All things Sunsynk (Deye, Inge, etc...)

But if it's loads on the non essential then it shouldn't affect the inverter?
Or are you saying that the big loads on eskom as the power is returning is affecting the grid stability that is causing the inverter error?

I actually noticed this behavior on my Deye today, just after load-shedding ended, my Inverter (8kva) was reaching roughly 6kw load, and the only power hungry "essential" item was the tumble-dryer (Non-Essentials would have been the geyser, the oven was off)

Could it be a firmware issue, as in the Interface shows this huge load (Essential + Non-Essential combined) but physically it is not the case (I have a CT installed)

I actually never look at the gauges so i dont know if the grid interface shows only what the inverter is drawing or if its the entire ct.
I only ever look at the sunsynk app or if I'm near the inverter I'll look at the "flow" or whatever you want to call it screen.

You might have more inductive loads than you are aware of for a 6kw spike.

That spike is more around 20kW :whistling:

There is a good chance the grid voltage is low and its a bit of a brownout. Its going to happen more and more as people get solar solutions and the draw at switch on gets bigger. If he is drawing close to the inverter wattage it will be a problem. Thats my theory anyways.
 
Since this afternoon, my Sunsynk sends me constant messages via the App every 30mins-1h30mins saying 'Disconnected from grid'.

it normally does this when load-shedding is active but now its doing it ALL the time since this afternoon. But if i look the grid is still connected.

Any ideas?
 
My sunsynk dongle still remains offline.
Any ideas. Should I send it in for a warranty claim ?

I had this a few weeks back, its super short intermittent drops in voltage that your inverter registers as disconnects.
There was a fault on the phase i was on that city of joburg needed to fix.
I was about to log a call when a neighbour on the same phase completely went down. After they fixed him, then I was sorted as well.
I would suggest logging it.
Here are screenshots of the alerts I received in a single day

I have a Deye 5Kw and two Pylontech UP5000's . I initially had the two connected using the RS485 ports, but there was no communication between the two. Changing it to the CAN ports solved that.

Just for interest, to use the 485 ports does something have to be configured?
I see one of the Sunsynk's screens has little tick boxes I don't remember seeing that on the Deye's menus.
And is there any benefit of one protocol over the other?

Yep that’s exactly what mine is doing. It’s a 3 phase.

Ok let me see and I’ll log a call. For some weird reason it stopped doing it since about 1am

Is it showing online in the app? At the bottom, under equipment ->gateway when was the last time it updated?

Yeah it’s not the dongle/software. It thinks the power is dropping. However as someone mentioned it might be one of my phases is registering a small voltage drop. I think it interprets it the same because it had to draw from elsewhere to handle it so it calls it a grid disconnect

A lot of the old electricians are finding it hard to switch to these newfangled computer thingies as well. Its not just new fly by nighters.

Aside from that, it looks like Deye does not perform any basic input validation on its UI, and this with a device that connects to the Internet?

My short to medium term security strategy is to go Solar Assistant, and only plug the dongle in when I need an update, because I forsee a global calamity pretty soon.
 
This morning I noticed my equipment tab in the Sunsynk Connect App has no devices. Then after a while, my inverter reappears but the graphs are all blank with no data.

Think this is a Sunsynk server issue? The home screen is still showing me current battery lever and grid/load usage, but the detailed equipment pages are all blank.
