Marine Solar Panels

Floyd Said:

how big of a pump can i run with a 12 v deep cycle battery and inverter?

We Answered:

Here is another idea you may want to consider. DC solar submersible pumps are available from Grundfos, Shurflo, and SunPumps. They work directly off of the solar panels. No batteries, no inverters. Just a small controller. When the sun comes up, it pumps. You are using a cistern, so you have a reserve for nighttime and cloudy days. These pumps are pricey, but between inverters, batteries, switchgear and efficiency issues, you are usually cheaper going this way. A little research is required to match pump sizes to your panel, and how many GPM you will get. Also look at warranties and availability.

is there a way to play an electric guitar with a car amp?

We Answered:

Just hook the headphone output from the laptop to the amp's low level inputs. That type cord is available at any Radio Shack. A small, battery powered stomp box or three, could take the place of the laptop. So you could have distortion, chorus, and delay, hooked directly to the low level amp inputs. We used to use battery powered practise amps, like a pignose, and a few stomp boxes to practise in the outdoors. Heck, I took the guts from a fuzz and a delay, installed them in my guitar, and plugged a Mr. Microphone into my guitar jack. Then I just tuned my car stereo to the right frequency, and jammed loud while sitting on a picnic table in a park. Cold brew is optional...
