Hi there. I have a AC200 Max to which I connect 3 solar panels of 400 W max. 2 in series in the PV input, and 1 through the AC adapter. I have all the 3 panels installed closed to one another. Same orientation, no shadow, all cleaned. I have tried to switch them and always get the same results : the single panel plugged to the AC adapter input is always above the 2 series panel plugged to the PV input. Absolutely not understandable… For instance right now, the AC adapter delivers around 50 V and 230watts, while the PV delivers around 90 V but only 240watts and sometimes less ! What’s wrong ? Thanks for your help.
- Please check the display, DC input source set to PV
- Try unplugging the PV charging cable again
We need more info. What is batteries SOC% displayed on the screen or App ??
.
When the SOC% approach 100%, the charge controller within the power station, will reduce the PV power it will take from the panels, and at 100% SOC% the PV power will be 0 Watts.
