Hey folks,
I have a project i am working on right now to try and take my pool pump off the grid. I have 5 SPR335's that I plan on using for the project, likely i will not need all of them ( the spot i have has space for 3 so that is what i have done the math on) so the others will be saved for another project. They didn't cost me anything and i don't want to tie this into the grid for a bunch of reasons so the why for this project can be saved for later.
I have 2 pumps, a 1HP pump for the big filter and a 3/4HP pump for the pool bottom shark cleaner. If we assume the 1HP pump runs for about 3 hours and 3/4HP pump runs for about 3 hours as well.
Using this website i would be using about 174kwhs a month to run these 2 pumps. http://www.myconserve101.com/energyS...poolPumps.aspx. Does this seem accurate to folks?
My calculations have annual production of 3x 335 panels at about 1,254kwhs with some shade and 1,456 with better assumed exposure, I need to get a suneye down there to get better accuracy. This is going to leave me a bit short so i may have to reconsider the number of panels.
I am the most stuck on the batteries and what type to choose to power the pumps with the above production assumption. Should i go with a deep cycle battery or a dual purpose? I need some help on calculating how many batteries i need to run the pumps for long enough.
I have an electrician friend that is going to help me wire it all up with charge controller etc.
Is there anything that i am overlooking at this stage?
Thanks for everyones help.
