February 22, 20251 yr Hi Guys. Can some of our members please try and sort out this minor problem on the inverter. 5 kW Deye installed 2 weeks ago. Settings: Always use 50 W from the grid. The CT is fitted and works fine. Do not export to CT. Supply LOAD 1st then charge battery. Timer is not ticked to use grid when the PV kicked in. The minor grid use during the night the timer was set to keep the battery SOC at a set level which is working as it should be. The question is why is there a purchase from grid (92W) when SOC is high (66%) over the always use setting of 50W. This increase over 50W only takes place when the grid kick in. Refer to the line at 06h15 when grid use ramps up. Load is only 81W and PV 27W at this point in time. Even during the day with below 300W load and 1250W PV I find it would use say over 450W from grid and the value over the 300W load would go towards charging the battey instead of just using PV. Again the timer is disabled during this time frame. If PV is switched off the grid use drops down to the setting value of 50W from grid. The 92W is not a train smash but over 450W is getting in the high area.

Just for the record the extra 40W used from grid tied in with the min power used from grid was because of the 2 solar sell options that the Zero Export to Load was ticked. This was not easy to spot during the bad PV weather last week. On Sunday with good PV the inverter started exporting in a big way. A good learning curve. Also a +1 for the current prepaid meter from Conlog. May I give a big +1 to @GreenFields for helping me out. For other members both the Solar Sell options must be unticked on the system page to prevent export and limit the always draw from grid to the level keyed in on this page.

Just asking stupid question does the solar sell override the zero export?

Not exactly overriding the zero export, it just introduces selling as a second priority. As opposed to "Selling First" mode when selling is... first priority. If you're in "Zero Export to CT" mode or otherwise "Zero Export to Load" mode, then by ticking the "Solar Sell" boxes you will indeed start exporting power once the battery is full, and if you've got surplus daytime PV energy. Bottom line, if you are not registered for export, then don't tick those options.

The sell solar was my 1st question when we powered up the Deye when I bought it. Just glad to know how the 2 settings work in relation to each other.
