Hey guys and gals!

I have been enjoying aquaponics for awhile now. This year, I am wanting to make my set up even more self sufficient and take it off of my homes power grid. It does not use all that much electricity, but a penny saved is a penny earned.


My questions are pretty simple, im sure someone with more experience will think they are common knowledge.

I have no idea how to figure out how much power I need to be able to produce, in order to run the equipment I have.

I dont have much plugged in, Airpump for aeration, my main flow pump, and a smaller pump that just pumps water up into a spray bar that empties straight back into the tank.

I have a Deep Cycle Marine Battery on hand, and I am looking at this solar panel kit and this inverter:

It is unlikely that that 20W solar panel will be anywhere near sufficient to keep your system running for any length of time, it is just too small.

Re that inverter, I honestly would not attempt to use it, you generally get what you pay for with this sort of gear. It wont be a sine wave inverter, the waveform will be something nasty- square and/or triangular and your air and water pumps will be noisier and may have a shorter life than if used with a clean power supply, and will not have as much output either.

What ratings are your various pumps, and the battery?
