jashwin Posted June 17, 2021 Share Posted June 17, 2021 Hi I have had the above 5kw hybrid inverter installed yesterday and it replaced a 2kw Powerstar IR standard inverter( both have 4x 100ah batteries).my question is with the old inverter the load was 0% when eskom power was on even when I used eg a heater on the plugs that ran via the inverter, now with the new inverter I see it has load on the inverter continuously on even when the eskom power is on. the unit is set to utility first option. I am now worried that I will blow up the inverter if there more than 5kw are loaded onto it even though eskom power is feeding it. I have tried to put unit into bypass mode by turning unit off but notice the load is still present on the screen. pls can someone guide if am doing something wrong or worrying for nothing. below is pic of unit in normal mode. the installer tells me I need to install a auto power bypass switch to fix the issue of loading the inverter continuously, thanks Rgds Jashwin Quote Link to comment Share on other sites More sharing options...
jashwin Posted June 17, 2021 Author Share Posted June 17, 2021 Hi, it's a king from what I have read. option 1 is set UTI. I dont understand why the load is through the inverter although eskom is on, I have checked the watts and Kw load and it goes to 3.7kw and more depending on what appliance is plugged in.

jashwin Posted June 18, 2021 Author Share Posted June 18, 2021 Thanks 87, I dont have solar panels yet . I get what you saying about just passing the power thru but I worry as I load the plugs I can hear the fan start to run hard like the inverter is working an needs cooling, that make me think is not just passing the power thru, also I see it seems cleans the AC feed from Eskom before it send it out. I just hoping I dont have a expensive bill it I go over 5kw as warranty wont cover it. regards Jashwin Quote Link to comment Share on other sites More sharing options...
JaseZA Posted June 18, 2021 Share Posted June 18, 2021 Remember this is a King unit and operates differently to the MAX/VM/MKS inverters in that it has zero transfer time and does double conversion. This means it must be in bypass and not line mode to purely pass through grid. 87 Dream 1 Quote Link to comment Share on other sites More sharing options...
JaseZA Posted June 18, 2021 Share Posted June 18, 2021 That being said, even if you were to overload it, it would bypass to grid or shut down depending on your settings. But it does use energy the whole time in Line mode doing the conversion. I'm not sure if it will use the battery to power loads when in Bypass if the grid fails. 87 Dream 1 Quote Link to comment Share on other sites More sharing options...
JaseZA Posted June 18, 2021 Share Posted June 18, 2021 (edited) Also, the fans will run if the unit is charging the battery. You might need to look at these settings and see what works for you. I imagine USB, ECO and BYE? Edited June 18, 2021 by JaseZA Quote Link to comment Share on other sites More sharing options...
jashwin Posted June 18, 2021 Author Share Posted June 18, 2021 (edited) Thank You 87 and Jaseza for the insight and feedback, I will try the above Edited June 18, 2021 by jashwin 87 Dream and JaseZA 2 Quote Link to comment Share on other sites More sharing options...
jashwin Posted June 18, 2021 Author Share Posted June 18, 2021 (edited) ok got to bypass mode, thanks Edited June 18, 2021 by jashwin 87 Dream 1 Quote Link to comment Share on other sites More sharing options...
jashwin Posted June 18, 2021 Author Share Posted June 18, 2021 It should be ok now , although it still shows the amount of watts running thru it? Quote Link to comment Share on other sites More sharing options...
jashwin Posted June 18, 2021 Author Share Posted June 18, 2021 I changed 10 to ECO in the setting, thanks for the help Quote Link to comment Share on other sites More sharing options...

No, it will go to bypass on overload (unless disabled), but yes, the power still goes through the internal circuitry of the inverter-charger. The circuit is rated for 40 A (your wiring may not be), so there should be no problem unless the load exceeds about 9.2 kVA.
