Trying to run a 300 Gal pond aereator 24/7?

Really UNATTENDED and BATTERIES are mutually exclusive. If you can live with great aeration in good sun, a
little in poor sun, and none the rest of the time, its possible to match up DC pumps to adequate panels to run
without batteries. Bruce Roe

UNATTENDED and BATTERIES are mutually exclusive? Wow, this is a pretty big disappointment. I had not considered that.

Well, operating battery systems that are being do require some baby sitting or at least occasional monitoring of operating conditions. So, don't shoot Bruce, he only knows mostly what he's talking about.

I will cut to the chase with no lip service and tell you what is needed based on your other thread.

Battery Capacity @ 12 volts = 40 AH
Panel Wattage required if a 12 volt battery panel using PWM 10-amp Controller = 100 watts
Panel Wattage required using MPPT 10-Amp Controller = 60 watts

Now you know why round 1 failed, everything was undersized.

Good Luck.

Thank you. I will google these terms and try to understand your recommendation. Any chance you want to just give me a parts list, ideally with Amazon links and everything?
