Hi guys,

We have a Deye 5kw inverter and would like our geyser to run as a non-essential load during high production hours (in excess of what we can store on the battery). The geyser is not connected to the inverter.

I have a smart timer on my geyser and this will switch on at midday (once the batteries have charged). On the inverter, I have "smart load" active and have selected "Zero export to load" and ticked the "sell" box. I can see that excess power is sent to the grid side (which I assume is to my geyser) when there is ample power generation, however, once the geyser timer has switched off the geyser there is still power being sent to the grid. Are my settings correct? Or am I feeding power to the grid rather than my geyser?

Thanks in advance!

Please post a pic of your settings page

You are selling to the grid according to the settings you mentioned so will be feeding to the grid.

Sounds like maybe your ct coil is not set correctly at the db board.
Ensure it is directly at the incoming grid at your db board and then check the settings to make sure to not export but allow to feed your local non-essential grid.
As @madness_za mentions, some pics of your settings and setup will help get more defined answers/suggestions

The correct setting is "Zero Export to CT."

And if you don't have special permission from your municipality to sell back electricity, and no special two-way meter, then do NOT tick the box for Solar Sell.

This will enable that when your geyser timer comes on, any available excess solar power will be diverted to your geyser.

This is on the understanding that your CT coil is installed correctly, which I assume for now your installer did okay.

Do this, see how it goes, give feedback if something still seems wrong. 

Thanks @GreenFields @WannabeSolarSparky and @madness_za for your suggestions. As requested, I have some images of the settings, the only setting I changed was to select "zero export to CT".

 

However, when selecting "zero export to CT" the readings on the home screen no longer displayed house usage, and seemed as though it was feeding back to grid? 

Can also see no usage tracked on the app:

 

I know the CT is installed as the mains power feeds the DB board. So I'm guessing we should try turn it the opposite direction?

 

Would be interesting also to see your SOC, grid power and battery power included on this graph. Easy enough to do from the SolarMan app by selecting additional parameters.

Also, I'd suggest to activate the Time of Use function, and during the time that your geyser is supposed to run, set the battery SOC to 100%, or else drop the "Power" column to 0. Just to prevent having the battery feed the geyser.

Thanks @GreenFields I have taken a snip of the additional parameters, and a zoomed-in version during the time frame that I selected "zero export to CT" around 6pm for about an hour. It was a very rainy day yesterday and had almost no solar production. 

 

 

I'm going to try turn the direction of the CT around this eve and see what sort of readings I get.

 

Also, I do use the "time of use" functionality- thanks
