I have a similar situation and I use a airmax PS10. https://www.amazon.com/Airmax-PS10-...irmax+ps10&qid=1640035753&sr=8-2

I have 400W though, and my battery bank is woefully under powered. I only have 200ah battery bank. I can run the pump for about 45 minutes straight then it needs to charge for 30 mins or so.

I can still get a solid 5 hours a day depending on the time of year. I'm down South TX though with lots of sun.

My inverter is 600w. I had a 300W, but it wouldn't start the pump consistently. I am thinking I need to add at least 200-300ah to my battery bank and probably another 200W solar or so to get it to run 8 hours.

So far though it's done the job. I have just over a half acre pond and ever since I started running it the pond has cleared up nicely and fish seem well supplied with oxygen.
