Hi guys, I have myself an AC200Max so its rated to take in PV input of 900w 145v/15A is it possible to combine two DC power source? I already have 2*550w 50v 14a that gives me total of 1100w 100v 14a for solar charging what if I also wire it parallel to the output of a Pecron Car Charger that is giving out 500w of 42v 13a?

So these two in parallel would give me total of 1600w 142v 17a is this right? will that be okay? Ive heard some say its ok to over-current just dont over voltage, over-power the AC200Max mppt will limit it to 900w is that right?

Im not planning to charge the AC200max this way but I will be wiring them that way for now since I cant find a 2-pole DC transfer switch yet to be able to switch from Solar charging and Car charging. But it could be possible option too to charge in both if its safe to do so.

No -

  1. The AC200MAX has one DC input.
  2. Your solar array already exceeds the 200Max rated input in W. Combining your proposed 2 sources would exceed the rated W input even further and not increase charge rate.
  3. They are different voltages.
    The only way of charging most Bluettis from 2 sources is; as near to max DC input and from AC input at the same time. Even so, at some point the power stations internal electronics will limit charge rate to protect the battery cells.
