June 16, 20224 yr Author So I emailed Deye support. They confirmed if you have essential circuits then you would not see the usage on the Grid Icon nor on the Home icon. Only place you will see it is on the CT value. This is really stupid on one hand as if I want to see if my solar system is really reducing my power usage I need to see total usage(essential as well as non essential) on the inverter icons as well as on the Solarman app(CT values don't count). So if I want to achieve total home usage the only way to achieve this in my opinion is to put entire house on essential side then every usage is shown on the inverter icons as well as on the Solarman app...

Yes it seems that inverter does not include the usage on the non-essential circuits as measured by the CT other than on the Grid screen. That being said I believe it is possible to direct surplus solar power (essential load met and batteries charged) to the non-essential home load that is on the same side of the CT as the inverter. I do not have solar panels yet so this is a bit theoretical to me at this point. What do you mean by "achieve total home usage"? Do you mean "show total home usage" or do you mean "supply total home usage with your solar" or something else? If you want to see if your power bill is dropping then check your bill... 😄 Bear in mind that LD is what flows through the inverter. As I understand it the inverter has a built in CT which measures this. I think this partly explains why Solarman and the LCD do not show the values measured by the (external to the inverter) CT. Btw it may well be possible for Deye to implement a feature to track (measured and retain) the grid usage as measured by the CT. One reason they may not be doing this as the CT can be omitted or placed in different places depending on the mode of operation. You may want to politely request this feature if it is possible. If not and you really want to measure your usage from the grid you get another energy meter and hook its CT clamp over the main Line wire from Eskom.
June 17, 20224 yr Author Yep, I wanted to get my total usage per month on both essential and non-essential circuits and wanted it in the app so it's easy to view and track.

If not and you really want to measure your usage from the grid you get another energy meter and hook its CT clamp over the main Line wire from Eskom. This is probably why Sunsynk upgrades the user interface on what is otherwise Deye hardware. If the CT is abobe non essentials and you tick zero export to CT you should be able to power non essentials. The display however will probably not reflect this in a very user friendly way. But between external and internal CT one should be able to figure out what goes to non essential.
April 10, 20233 yr Hello, how can Deye know the difference between essential and non-essential load since it has only one load port… I have a 8kw hybrid single phase.

April 10, 20233 yr The 'non essentials' are connected directly to the grid before the inverter. They dont go through the inverter at all. The way the inverter knows about them is by means of the CT coil. Thats how it pushes back extra PV to the non essentials.
April 10, 20233 yr It's a bi direction inverter. The ac input is also an ac output. This is the nonessential side.

The non essential draws from the grid when the inverter cannot supply it.

Disappointing as I will never know my true usage of my house per month.... Hello. It is disappointing. My question is around knowing if the system provides power to the non essentials. If the batteries are fully charged and you dont push back the inverter will limit the production to what is needed to cover the essential load? If that is the case and I then switch on lets say an aircon then the solar production should go up? Or am I not understanding how it works?

Yes if your settings are correct and battery charge is not set as 1st. If battery is full then any surplus PV goes towards loads on the non essential if the grid is on.

November 25, 20232 yr 3 minutes ago, Pjs100 said: And in my example you will see the PV production number increase? Yes, it can work, you can produce a jump in extra power to supply to the aircons. There are just some settings to bear in mind. Firstly the System Work Mode must be "Zero Export to CT" on the Deye, while Sunsynk has its own name for that function. Secondly, at that point you should be aware that you will be sending surplus solar power AND battery power to the aircons unless you add a few more settings. If you don't want to drain the battery for aircons or other non-essential loads, then I'd suggest you set up the Time-of-Use timer - specifically during the time slot when the aircons and battery are expected to be running, set the "Power" setting on the timer page to zero or something low like 300W.
