chrisc Posted May 13, 2023 Share Posted May 13, 2023 (edited) Good morning Recently upgraded to a Kodak 7.2kW inverter. Its being used with 6 x 450 watt panels and 2 x Shoto 5100Wh batteries Location 01 refers to the Output Source Priority Have tried SUB and SBU. On the SUB setting, I notice that the inverter displays "Bypass" all the time during the day. Currently the load is 335 watts and the combined input of the PV panels is 217 watts The displayed PV wattage seems low compared to the old inverter. Is some of the PV input being used to charge the batteries? On the old inverter, "Bypass" only came on after dark with no solar input Would you say that the SBU setting is the same as the old inverter Thanks Edited May 13, 2023 by chrisc Quote Link to comment Share on other sites More sharing options...

But if it didn't have SUB output priority, then SUB will be different to anything you've had before. It says it's in bypass when the grid is available because it's operating more like a hybrid inverter in this mode; blending PV, battery, and grid. Axpert MKS models, and other models that don't have the high PV voltage solar charger, can't blend grid with anything else. Quote Link to comment Share on other sites More sharing options...
chrisc Posted May 13, 2023 Author Share Posted May 13, 2023 Yes, looking at the indicators, it states that it is using PV power and Utilty power at same time There was a 2-hour blackout a while ago, then the indicators showed PV and battery The old inverter was an Axpert 5kw which I bought in 2016 Quote Link to comment Share on other sites More sharing options...
