    Getting the sun to pay for my pond aeration costs.

    NOT LOOKING FOR DC PUMP SOLUTIONS: THANKS AFORETHOUGHT!

    This equipment I have, and it is electric, and if I'm out of bounds trying to get solar to power what I have, then I apologize. SO. . . .

    . . . . I have a vevor 3/4 hp aeration compressor that uses about 600 watts starting power. I have this cheap inverter 30 amp. https://www.amazon.com/dp/B07R8TRJ8C...t_details&th=1

    I also have a 1000 watt dewalt inverter.

    I have a bunch of 24 volt solar panels, I think 90 watt each.

    So, I think I have to wire the panels in series not to exceed the voltage for the inverter, or do I?

    I have a 12 volt deep cycle battery.

    My goal is to run the aeration during the day. If I could abandon the battery, that would be cool, as maybe the panels could keep it running, or does it need the battery to start the compressor?

    Maybe a bit of a wiring schematic would help with the awg for wire if it needs the care on the load end.

      The elegant solution is to find a DC motor pump intended to run
      directly from solar panels. That to run when the sun shines, and
      slowing in times of poor sun. You may have twice as many panels
      as such a pump needs, if so I would form 2 strings oriented more
      east or west, to give you near 8 hours of full speed operation.
      good luck, Bruce Roe

          For a 20' deep 3 acre pond? DC? I haven't seen that beast yet. Do you know of one? But I want to use what I have. I'm just a bit confused on the wiring of the panels, parallel or series, as the controller says not to exceed 24 volts, so in series, wouldn't that exceed it?

              Yes. Series wired will not be good for you.

              For that matter even one of those 24V panels will put out more then that voltage. What is the make and model of the controller? Without that information you may have to get another one to make your system work.
