Mercadian Posted August 11 Share Posted August 11 Good morning all, We have recently added in a third Deye 8KW inverter and an additional 16 solar panels. This bring our setup to a total of 3 x 8kw inverters (1 x 8KW with 46 Panels (18 x 450w JA panels, 12 x 565W JA Panels and 16 x 545W Canadian Panels) this configuration means our batteries are fully charged by about 12PM. The problem with this is that the inverter uses the eskom load to off set the solar deficit and not the batteries. However, this picture changes at about 6PM or so. The work mode settings look correct from what I can see. Quote Link to comment Share on other sites More sharing options...
Nexuss Posted August 11 Share Posted August 11 Sounds like you have SOC set too high for the daytime. If the battery is at 100% and the corresponding timeslot SOC is set to say 50% it should supplement with the battery. Quote Link to comment Share on other sites More sharing options...

Good afternoon, All time slots are set at 20%, have just made sure that the days are all ticked as well and I have even tried to untick the grid charge setting. But same thing.

Sorry just wanting to confirm. The battery setting has Gen Charge, Gen signal, Gen force and Grid Charge ticked. Work Mode is set to Zero Export to Load and Energy Pattern is load first. Zero-Export Power is 100. Other settings are as per image. I’m pretty sure all the settings are correct and it might be a firmware bug, but maybe missing something. The installer is comming around to look tomorrow as well. Quote Link to comment Share on other sites More sharing options...

I meant the Work Mode to be set to load 1st which you have ticked as indicated. Quote Link to comment Share on other sites More sharing options...

It is on the master inverter yes, settings have carried across to the other two inverters. I did speak to the installer and he got Deye to run through a firmware update process again. The master inverter now has the following versions: HMI Version: 0000-C36F MAIN Version: 0-6027-1724 Both Slaves have the following versions: HMI Version: 0000-C36F MAIN Version: 0-6027-1724 Looking at Solar Assistant now after the firmware update batteries are reporting as 99% and the solar is enough to run the house load. Grid power is between 76w and 120w which I would expect as the Grid Trickle Feed. So I am wondering if there was not an issue on the previous firmware on the master inverter. Will see what happens if the batteries report as 100%. CAN cable is plugged into the master inverter.
