thank you, I did calibrate it originally hooked up to bench supply... but going of the values I was getting this morning, ether the current sensors I have installed are inaccurate or ( most likely) I've stuffed up the calibration, output current was higher than input via wattage on screen... Ill let it run for a bit and bench it again to calibrate it..

but on a positive note,  by the lcd it was delivering about 2.6kw for about half an hour at its peak ( around 2.2 - 2.4 constantly), done 11kwh today so far...and inductor was warm, I could hold it, and mosfets were barely warm (41°c - 42c max by the sensor) ... attached is a pic from earlier ( around 11am) .. by the amout of panels connected thats about right too..
