Anybody got any ideas? looks like about 5 K is about as cheap as I can get it if anybody has any experience with any off-the-shelf items I'd love to hear about it A particular interest are the inverters. They seem to be quite pricey
hey thanks for pointing that out I'll try and fix the title I've always had trouble with zeros and I am an engineer and it has cost me many times There now I have the correct units on the stoichiometry .Thanks much!
3500 kilowatts = 3,500,000 watts. You probably don't mean that. Is this for residential? RV? Yacht? What are your power demands? Do you want air conditioning? Are you retrofitting an existing home or designing a new one?
Off-grid tiny house living in a good environment weather environment is of Interest then again it would be nice to just have a system you could just unfold uncrate unpack set up and go It would probably have to be mounted on a big trailer I have various needs for various load demands
Do some research into RV solar systems. They focus on power management and relatively low cost. They have very efficient refrigeration and even electric cooking systems designed for running off of battery banks. Also look into wind generators, commonly used on sailboats. The sun doesn't always shine.
it's disappointing Amazon doesn't have it I guess it's my job to design it build it and get it for sale there Of course funding is always an issue
Doesn't have what? I live off grid and generate my own power through PV panels. I try to use everything in 12v and only use inverters when absolutely necessary. TBH if you live in a house you probably get a better ROI on solar water heating than PV.
Not enough info here. 3500 Watts is only the demand, what is your duration? You need to figure it into watt hours or kilowatt hours then into amp hours. Once you know this, you can calculate the size of your battery bank, once you know your battery bank, you can size you PV arrays to maintain the bank. Keep in mind that your array isn’t going to operate at 100%. When they get hot or dirty the lose capacity. Your latitude, hours of daylight, weather need to be figured. Also every step has a loss. Nothing is exchanged on a one for one basis. Your charge controller is going to have a loss. Converting electricity into chemical energy (battery) is going to have loss, converting chemical energy back into electricity has a loss, inverters have a loss. Then you need a back up, grid power or generator so your expensive batteries don’t sit at a low state of charge for an extended period such as prolonged weather event or equipment failure.
I really need to work up a spreadsheet of water hours buy specification and battery type Are lithium ions good?
here a few links to 'all-in-one' ready to go, prewired systems... note the battery options change the price drastically, for a typical 3600w system, lion batteries will add almost 10 grand usd to the price... https://www.altestore.com/store/sol...sidential-solar-power-system-base-kit-p40464/ http://boxedsolar.com/complete-battery-based-off-grid-solar-systems/ https://www.wholesalesolar.com/solar-information/off-grid-living https://gpelectric.com/application/rv-solar-kits/ https://amsolar.com/ https://www.wholesalesolar.com/rv-marine
