This project shows you how to generate Off grid AC Power using a simple Solar power station with 2 batteries.This system can provide enough off the grid power to run your appliances around the house.You can easily run light,a laptop computer, small tv and fan for several hours.
Most of the item required can be bought from your local store or Amazon.The rough cost of building this system is as follows :
$150 for 100W Solar Panel
$75 each for 2 batteries.
$20 for 400w Inverter
$40 for charge controller.
The whole system comprises of four things, a couple of batteries, inverter, and a charge controller.The inverter is purchased from Harbor freight ,the charge controller from fry electronics.The deep cycle batteries are from Walmart.
So you start by setting up your panels outside. In this case, I have six one amp panel set up, 15 watts a panel, so that’s 90 watts coming in.
I lead them straight down to the main connection, it’s just the six black wires all connected together and twisted tightly to that extension cord wire and the six red ones connected.Feed the line into your house,goes straight to the charge controller.
The output wire from the charge controller goes into the battery.So solar panels to charge controller ,charge controller to lead battery in your bank.And as you want to expand this to two,three or more batteries, just use some automotive cables and go from positive terminal of one the positive of the other. And with a black wire, negative terminal to negative terminal, the other one.
When you want to run something, just get your inverter that converts the power from DC to AC, take the clamps, clamp them onto that same lead battery in the system. So again, red to the positive side, black to the negative side and flip it on.
So remember, when you hook things up like an inverter, or the charge controller or voltmeter, anything you’re going to hook up on here, make sure you always pick one of the batteries to be the lead battery and hook everything to that. Whether you parallel one extra battery with it, or five or six or however many you want to put on there.
Also added here is a lighted voltmeter which gives you a constant reading on your battery bank so you know exactly what’s going on with it at all time.
A simple system that can come really handy during a power outage or in any emergency situation.
- DIY Video : How to build a Survival Water Distillation System for under $5 and turn Salt Water Into Fresh WaterThis project goes into the build a simple survival water distillation system to turn your salt water into drinkable fresh water. This setup can be made with little more than two glass bottles, some metal trays and some sand. So the primary components of this setup are two glass bottles, the wider the bottles are in diameter ,the better and a pair of metal trays. The first part of this process will be to prepare an area such that the two bottles can rest mouth to mouth. The important part is that one of them needs to be suspended over a heat source. This could be done over an open campfire, you just need to find a way to suspend the bottle above the flame either using rocks or logs. Cut a small notch on one side of the pan so that the neck of the bottles can sit a little lower in the pan. This is by no means necessary, but it will make the setup a little more secure. With the trays secured in place, both of them are now filled with sand. The sand will allow the trays to more efficiently act as heat sinks, one tray to cool one of the bottles and the other tray will be used to very evenly heat the other bottle so that it doesn't shatter from being heated too much on one side. The bottle is pressed firmly into the sand so that it gets good thermal contact and will be heated evenly. The second bottle is adjusted such that its mouth will meet up with the first and it is also pressed into the sand to obtain good thermal contact. Another reason that I'm using sand for this is because it makes it very easy to adjust the bottles angles and it is best to make the bottles meet up as evenly as possible so that there is not much room for water vapor to escape. We want it all to make it into this second bottle where it can condense as freshwater. As an additional measure to keep the cold half of the bottle cold, we wet the sand on this bottle with water or cover them with a wet cloth to allow evaporative cooling to take place. With such a large quantity of sand in this tray it does take a little while for it to reach the boiling point and get this process started. But once the sand has reached that point, it stays hot for a long time. So it is a pretty quick process as the water boils dry in this first bottle to simply refill it and you can continue on with the distillation process as long as you want. Rotate the bottle so that the top portion becomes hot from the steam, it is rotated into the cold sand below. And in that way the entire bottle maintains a cold temperature which causes the distillation to go much faster. https://www.youtube.com/watch?v=R_-wFiFdwAE
- How to build an Offgrid Wood Gasifier that can produce alternative free fuelThis project goes over the build of a cross flow wood gasifier that powers a generator or a car or any kind of internal combustion engine using nothing more than wood scraps, paper, coal or any other organic materials. This unit was built in nothing more than an angle grinder, and a hand drill and parts that you can find lying around. These devices are taking advantage of a process called gasification, in which you can take any kind of organic biomass, really anything natural that burns and by heating it up, you are able to break it down through a process called pyrolysis to its basic elements. This creates a gas called syngas or wood gas. Here we are burning biomass in an oxygen deprived environment. And that heat which is sustained through just enough oxygen to not spread to ignite the gases produced by the heat interacting with the surrounding material is the process that we are using to create wood gas. The gases coming out contains things like water vapor from moisture content in the wood, also creates tar and creosote .So we need to filter out the gas. And the main concern of getting that gas to be clean enough to run an engine is by cooling it down. We connect the unfiltered gas coming from the pressure pot into a radiator to cool it down and then further connected to a bucket filled with saw dust to filter . The reactor unit is made of an old 5 gallon painting pressure pot . The first step is to burn it out removing old residue and paint. Also burn out the inside container as well. Make sure everything on the lid of the pressure pot is removed and sealed off with a plug or bolt. Remove the rubber gasket on the backside of the lid. The holes on surface of the lid are covered with three eighth inch bolts. At the bottom of the pot , we attach two pipes for the the air intake and the syn gas suction output. These pipes are held tightly to the pot with the help of one and quarter inch pipe flanges. The air comes up from the bottom, the gasification happens in the middle of this reactor and the ash gets sifted to the bottom through a passive shaker grate. The output pipe is capped at the top to prevent the residue ash going out and small holes are drilled along the pipe to allow the wood gas to pass through. Next step is to build the grate insert where the fuel will actually sit on and burn on. The grate will sit about two and a half inches off the bottom of the pot. The grate is made from the other stainless steel container that came with the pressure spray painting pot. Grid of holes are drilled along the surface of the grate using a quarter inch drill bit. The grate is finally is inserted into the reactor pot chamber . The gasket on the back of the lid of the pot is removed and replaced with fiberglass rope that can withstand temperature up to 2000 degree Fahrenheit. The rope is secured in place using a gasketing cement and stove sealer. The lid is clamped in place until the gasket cement is dry. The next step is to build the cooling and the filtering system. To get all the tar and steam to condense back into their liquid form , we use a old oil heater radiator that act as a condensate catcher . The gas coming out of the reactor is connected to the radiator which gets most of the heat out of them. We build the filtration system using a 5 gallon metal bucket to get the gas as clean as possible. The output pipe is attached to the bottom of the bucket using a flange. The bucket is filled with a filter medium such as wood shavings or sawdust that will trap any sort of particulates and get more tar out of the gas. An old car blower from a toyota is attached to the top of this bucket to get that gas up to the point where it can burn. The blower motor is supported with a old 10 tin can that is then secured at the center of top of the bucket .Another soup can is soldered to the 10 can on the side to attach the output hose pipe. We don't want there to be enough oxygen to actually just burn all the material in there before we can extract the gases . So we are limiting this by using a one way gate valve . The one way valve is important to prevent flashbacks if too much oxygen is there inside the reactor . We load the reactor with wood sticks and put some starter down in there, which is just some cloth, some paper and a sprinkle some wood pellets on top just to give us something small to start off with. We pack the reactor leaving a spot in the center . The fans is turned on and we start the ignition process. https://www.youtube.com/watch?v=Bvl5XxVVjDM
- How to build an Off grid Rocket Mass Stove Hot Water heater using Copper Coils, Clay ,Sand. Also works as a cooktop!!!This project goes into the build of an off grid rocket mass heater for heating water without propane or electricity. This system also doubles as a cooktop. This rocket stove is really efficient and can create tremendous amount of free heat from little pieces of wood. The materials you need to build this rocket mass heater are copper coil , PVC pipes to make mould, clay and sand mixture, a frame for support, storage tank or drum ,oil, wood as fuel. The stove sits on a frame made from a wooden piece. Here an old chair is used as a base for support. The cob mixture made from clay, sand and water is poured on top of the frame as it is raised up. The next step is make hole for the air intake at the base of the stove. Also another hole is made for fuel intake at an angle to the base. We use PVC pipes as mould to make these holes. We lubricate the pipes with oil before covering them with mud so that they can be easily removed once the mould has been set and dry. A half cut lubricated PVC pipe is placed at the base of the support frame in front of another PVC which forms the body of the stove where the copper coil is wrapped. We start covering the PVC pipes with clay and sand mixture around the junction where the pipes meet. Once the mud has been filled and raised up , another PVC pipe at an angle is placed for the fuel intake. The copper coil is inserted into a well greased up PVC pipe . This section acts as the burn chamber where the coil gets heated up with the water inside. The coil is extended at the ends for the intake and the outlet .The bottom side of the coil is the intake of the cold water and the top for the hot water outlet. Fully pack the area around the copper coil and sides of the PVC pipe with the clay mixture such that the copper coils are completely covered . Pack the clay till you reach five to six inches above at the end of the pipe . This is done so that the top can be used for cooking or boiling. Once the clay and sand mixture is completely dried and set, we slowly take the PVC pipes out. Dig out the back end of both the holes so that all of them are connected to form a elbow shaped hole. The intake and the outlet copper tube is then connected to a water storage barrel. The intake pipe is connected near the bottom of the barrel where the cold water settles and the upper end of the copper coil is connected at the top where the hot water is collected. So the cold water that flows into the rocket stove, gets heated through the copper coil, and then due to the thermosiphon effect and natural convection ,the heated water is pumped through the other end of the coil on to the top of the barrel and this way the water is recirculated without the help of any external source. The cold water natural sinks down due to its higher density .The hot water becomes less dense once its heated , therefore it expands and rises up the coil to the water storage tank. Make sure that there is a height difference between the rocket stove and the water storage tank . The rocket stove always should be installed below the storage tank so that cold water naturally descends down into the stove and there is no backwards flow . https://www.youtube.com/watch?v=EUnQVIlAn6M
