@dognose @dfaber here’s another example of non-optimal performance caused by the DESS scheduler not projecting the ~400W continuous power draw of the inverters (Friday April 11) VRM did a good job at projecting PV production and consumption for the day. When the day started, the system was projecting an ending SOC of ~30-35% (sorry, I forgot the exact number). The DESS schedule showed no grid consumption between 12:00 through 20:00 (peak hours). Unfortunately, the ~400W inverter power draw contributed to a revised DESS schedule in the afternoon, resulting in grid consumption between 16:00 through 20:00 (half of the peak hour period). In the screenshots below, taken at the end of day, it can be seen the system reached the min SOC of 20% by 20:00 (due to the revised DESS schedules, impacted by the ~400W power draw of the inverters). I believe the optimal performance would have been to schedule a short charge at 11:00, prior to the peak period — charging enough to last from 12:00 to 20:00 without gird consumption. During the spring / summer period, this shouldn’t be a big deal - but during fall / winter, I can see this causing significant issues. Can this be addressed in a future update of the scheduler? Thanks very much ![IMG_0092](https://europe1.discourse-cdn.com/victron/original/3X/d/e/de53509150229e22227c1614d32b821689f40ca6.jpeg) ![IMG_0093](https://europe1.discourse-cdn.com/victron/original/3X/1/1/116def889d7dc50f26277184a22e2da0783161cb.jpeg) ![IMG_0094](https://europe1.discourse-cdn.com/victron/original/3X/d/5/d59c77680de27832e9886b8ce383dcd8714f75bb.jpeg) ![IMG_0095](https://europe1.discourse-cdn.com/victron/original/3X/0/2/02ec3fa7af5fc039b226ab56ae03559eb9b92740.jpeg) --- _[View the full topic](https://community.victronenergy.com/t/dess-slowly-discharging-battery-when-scheduled-to-keep-target-soc-flat/25925)._
