Ryanwb1 Posted March 5, 2020 Share Posted March 5, 2020 I got the Mecer Axpert MksII installed in my home.The fans run 24/7 whether they charging batteries or not.Its rather annoying. Does the Axpert Kings fans run all the time as well? Quote Link to comment Share on other sites More sharing options...
Milkyway Posted March 10, 2020 Share Posted March 10, 2020 Yes they do run all the time. The speed vary for time to time as the load ect. change. Ryanwb1 1 Quote Link to comment Share on other sites More sharing options...
0 |>\/\/3|<|<3Я Posted March 10, 2020 Share Posted March 10, 2020 The fans are always at high speed when the Axpert King runs in online mode (setting 10 = ONL). This is the default setting, which means the King will always have noisy fans if no settings are changed. I don't mind the noisy fans when using the batteries, but wanted less noise when utility power is available. To achieve this, use setting 10 = ECO. Then the fans idle along until the inverter switches to online mode. Coulomb 1 Quote Link to comment Share on other sites More sharing options...
Ryanwb1 Posted March 12, 2020 Author Share Posted March 12, 2020 Unfortunately my MKSII does not have this setting which is really frustrating.I have resorted to switching the inverter off when there is no load shedding and we are not at home. As you said i dont mind the fans running while charging batteries but when totally idle and doing nothing those fans shouldnt be running. I appreciate the suggestion however Quote Link to comment Share on other sites More sharing options...
moec Posted March 16, 2020 Share Posted March 16, 2020 As a side note, how good is the Mecer axpert mksii? I am looking to avoid load shedding and perhaps expand to solar at a later stage. Quote Link to comment Share on other sites More sharing options...
Ryanwb1 Posted March 18, 2020 Author Share Posted March 18, 2020 Seems to be good so far I like it except for the 24/7 fan thing....if it's going in your house that could be a problem but depends where you put it...I now switch my inverter system off completely until there is load shedding...I switch it on 2 days a week when at work to charge up the batteries as they will lose 3 percent a week Quote Link to comment Share on other sites More sharing options...
