October 13, 20232 yr Good evening, my photovoltaic system has a SUN-6K-SG03LP1-EU deye inverter, with a 14kwh storage system. I noticed that the electricity consumption of the inverter is consistently 250-300W. I think it's too high. What do you think? All my loads are under the UPS output, and if I open the inverter switch, the loads consumption goes to zero.
October 14, 20232 yr If you mean the 252w load on that image that’s not the inverter draw that’s what is on your backup/essential/ups circuit. When power goes that’s the load that is backed up

October 14, 20232 yr No .. Your internal consumption is actually 571 + 20 - ( 252 + 265 ) = 74W , which is roughly the same as the average on the Sunsynk You have load on UPS as well as essential. Internal sunsynk power usage is not shown as load from what I know Edited October 14, 20232 yr by Gary Waterworth

Internal sunsynk power usage is not shown as load from what I know You mean UPS and non essential (as far as I understand UPS and essential is the same). Don't know the Deye interface, but guessing it should be similar to Sunsynk. Seems like there is load on both essential and non essential even though this is inconsistent with what the OP is saying.

All my loads are under the UPS output, and if I open the inverter switch, the loads consumption goes to zero. I had a similar situation, although my setup is a little different. My 5kW Deye was operating in "Zero export to CT" mode with Solar Sell. I have loads also on my non-essential side, but the inverter's power to the non-essential always seemed well higher than the loads knew I was using. In my case I am also registered for exporting to the municipal grid, so I activated "Selling First" and the load reading immediately dropped to my actual usage while the selling to the grid spiked up by the surplus I was generating. As if the surplus was being used internally even though the battery was full and it should have started selling. If you can legally export, please check if it makes a difference for you too. Why it does this? I've had a theory that the solar/battery in the CT mode was also being used to supply reactive power, or otherwise keep capacitors charged to help smooth the supply when running from unstable solar and battery blending, if the grid is not supposed to be used a "ballast". Truth is, I don't know what I'm talking about, and I really have no idea why this happens.
October 15, 20232 yr Author Good morning i can't understand. language probably doesn't help. I'll try to explain it with the help of the shelly meter. All the loads in my house are connected to the UPS output of the inverter. in this other example I have a total consumption of 108W, detected with a meter on the electrical panel of my house. The "AC" output of the inverter is directly connected to the grid, without any additional loads. Deye cloud shows me a home consumption on the UPS output of 148w, and an additional consumption of 269W. The first is similar to what was detected by the shelly meter, but the 269w are not tied to any load.
