Hi @Buyeye, Thank you for your advise! Changing setting 12 (B2AC) to 21% and 01 to SUB did the trick, the inverter is now preferring Solar to utility in the day when its available!! Solar usage today is 3x what it would normally be!

@Ismail K agreed, that was my understanding as well, although looking at your stats your utility usage is very low when solar is available (although not 0). Today is very overcast here, so cant really say if the settings Buyeye supplied worked, but I will keep an eye on it and post an update.

Hi Ismail, My solar usage is really low and flat vs my load consumption and import. This is a normally sunny day yesterday If I switch off the utility, solar usage ramps up and matches my load. Which to me should be default behaviour, even if the utility is available!

Thank you for the reply Buyeye! I have changed setting 12 to 21%, the inverter wont allow 20%, I think that's because setting 21 (CUT) is at 20% currently. I will give that a bash and see the difference and then try setting 13.

Hi, Please assist, my current setup is working well. Except one issue, the inverter is using the utility to run the load and charge batteries instead of using the solar when it is available. My average Solar production in the day averages around 1.2Kw, if I switch off the utility however this ramps up depending on the load but can range anywhere from 5Kw to 7kw for the day. The average load on the inverter is only around 12%. In live monitoring with utility available, solar will provide 101W and Import will be at around 461W, so 3/4 of the power is almost always from utility. How do I configure the inverter to only use utility when the solar is not sufficient? Currently I need to manually switch off the utility every morning to "force" the inverter to use solar. My setup is follows, Inverter SPF 5000es PRO Serial # CQH1B1607N 2 x 5.1Kw Shoto Lithium Ion Batteries SOA10-48100 6 x 330W solar panels. The inverter is set as follows, 01 -> SOL 05 -> LI 36 -> L52 12 B2AC -> 95% 13 AC2B -> 99% 14 CGPR -> CSO 21 CUT -> 20% The inverter BMS port is connected to Battery 1's CAN port. Battery 1port RS458B is connected to RS485A port. Any advise would be appreciated.
