February 6, 20242 yr Hi all, My Deye 8K is continuously importing about 20w - 30w during the hours of non-generation. This can add up and lead to buying units at the more expensive tariff I would much prefer to have a continuous export of the same amount. I previously had a Sofar ME3000 which had a CT Colibration option where you could set an offset of the CT value. Is there any hidden engineering meny that would have such an item ? thanks in advance Edited February 6, 20242 yr by championc
February 6, 20242 yr I would first be sure that I'm signed up to sell back to the utility, and that I have a bi-directional meter. If you don't have those two things in place then you may find that your meter doesn't know the difference between and import and an export and either way you pay.
February 6, 20242 yr On the Work Mode settings page, what value do you have for "Zero Export Power?" If you reduce it to the lowest possible value you can WITHOUT the meter tripping, that should hopefully give your best results.
February 9, 20242 yr Author I can export power I have the Zero Export Power set to 000. If only there was a CT Calibration menu to set an offset value. The Sofar ME3000 had it, and it was so useful. You'd almost expect a hidden engineering menu, with access to a CT Calibration figure
February 21, 20242 yr Author Hi all, I found a solution, and I thought that it would be good to share it with everyone, in case that someone else would like to do the same. I suggest that you ground the Negative side of the CT clamp. So connect pin 6 to the CT and also to the Earth on the right side of the Inverter

When my CT is not connected there is always a -22watts on the Grid Power CT. Someone told me it might be a grounding issue. So maybe this is related to this however i need to understand how and why would this solve the issue
