November 10, 20223 yr Good day all, I have a 5Kw Deye Hybrid Inverter and lately I am noticing something strange when it allocates power. I had it for just over a year now, but only realising now as I am pulling stats on it on a more regular basis for a HomeAssitant Dashboard. In this example there is more than 2Kw of power available from the panels and the battery is fully charged. The current Load consumption in the house is 482W, Battery is pulling 222W (which in a way makes sense due to trickle charging). The panels supply 599W and then for some strange reason there is a pull of 139W from the Grid. The "Zero export power" is set to 40W. I would expect to see n Grid pull of 40W and all the rest coming from the panels as there's way more than enough to provide the 702W required. Please see screenshot below. Thanks Kind Regards Jeremy

Thanks Kind Regards Jeremy Did this happen for a prolonged period or was it in an instant? I've noticed mine will do this in bursts when the load increases / drops but performs as expected when the load is constant

But I do believe it is intermitted, it definitely does it when large power draws happens, i.e. geyser switches off. The bigger concern is that it will last for about 5 minutes or so. Not sure if it is something to worry about, its just frustrating giving Eskom money when it's not necessary.

Since you are on SOlar Assistant at least you can review the graphs in detail and see if this is a persistent issue. In the 24hr scheme - how much does this actually impact your Eskom usage?

At this point I am not too sure what the impact on Eskom really is, but it must be minimal. My best guess is around the 5kWh mark per month, I know it is insignificant, but it's an eyesore
