This is for an ultrasound emitter that kills algae cells in our pond. It operates 7 months out of the year.
Would the length of the cords cause overheating, excessive resistance, or otherwise not deliver the power needed? The 110v outlet is 300′ away. I’m also assuming that it would be cost prohibitive to run an underground electrical line and that the electrical lines used for outdoor landscape lighting wouldn’t work since this plugs directly into a 100v outlet.
Hi, I found a link where u can try.

A 16 gauge extension cord will work fine. 16 Gauge cord with a length of 300 feet will handle up to 1250 watts.
it will work fine because the 15 watt load is very low
15W. is about 0.12A. and the length of the run is no problem
as far as resistance is concerned.
I am however concerned with leaving an ‘indoor’ rated wire exposed
to the elements for so long.
You can expect UV degradation of the insulation of even ‘construction’ rated
extension cords over the kind of time periods you propose.
Below is a link to a solar product — no wires necessary. They sell solar panel for the algae kiler and the algae killer itself.
Also, you wouldn’t have to worry about lots of wires, just short cable from solar panel to pond
Running that much cord could start a fire! If you have an outside electrical box you can get an extension for it and run a 12/2 UF cable 18" deep over to within 10ft. of your pond and install a GCFI wp outlet, this is something you could do yourself, if you buy from Lowes or Homedepot have them show you how to hook it up, turn off the power before tying it in.
