Hi Smirresa, Yes, setting 11 set to 2A and setting 16 set to CSO. In CSO the inverter will only charge from utility in bypass mode when there no solar. If you are in bypass mode, but there is solar (cloudy day with batteries low), then the AC charge will not occur. If you are running from batteries and no solar (at night time) then the AC charge will not occur. AC charging will only work when you are in bypass mode and no solar. Regards

I had the same issue with the Error8 when my inverter(s) are in bypass mode, no solar input from panels and rain in the air. My approach to solve (hide) this is to not add any additional hardware to the setup. Enable an AC charge current of only 2A and switch the inverter charge priority to "Solar First". The MKSII inverter can only charge from AC when in bypass mode, thus it will not use the AC charging when there is still battery available. AC charging will not be used in bypass mode with solar availability. The 2A AC charge setting is only enough to bias the inverter and do not really charge the batteries over the night period (My batteries SOC will go up with 1% maximum after about 10 hours on bypass). After enabling these settings on my inverters I have not experience Error8 again for the entire winter (lots of rain and bypass mode incidents). I hope this helps a few of you.

Who is your supplier?

Hi Coulomb. Did you guys worked out if these Kodak MKSII (OGX5.48) are clones? I have the same inverters on 71.70 and tried to update the firmware on the units without success. My labels looks identical to the one in the picture above.
