  1. I am facing the same problem. I am failing to switch off utility mode untill I restart the system. I am using SAKO inverter, on the user manual setting 10 is output voltage
  2. Hello, I have 3 No. 5KW SUNPOLO SAKO inverters connected in Parallel with 27 No. 320Watts Solar panels (9 no. 320Watts connected to each Inverter), 2 No. 200Ah 48V Lithium Ion Phosphate Batteries. The Inverter is connected in SBU mode, with setting 16 on OSO. My priority is to deactivate Utility power to the Batteries and load so I can enjoy Savings from the Grid. I have set OSO on timing mode (from 7am to 9pm). My concern is that when the Batteries are discharged (to under setting 12 voltage), utility power takes over, however after the Batteries are charged utility power does not cut off automatically untill I reset the system manually. Also during the day when we have abundant sunshine, once utility power is connected to the load and the Batteries, it fails to cut off. Please does anyone know how to automatically switch off utility power once the Batteries are charged. Thank you
