Homemade Solar Battery Charger

!±8± Homemade Solar Battery Charger

It is possible to build your personalized battery charger making use of solar power for a lot less capital and effort than just you could think. These kinds of systems are useful to charge a computer, revitalise a golf wagon, run a stereo system at the shore, and a lot more. They're easy to build and also will save you funds and also allow you to keep your peace of mind (and protection) during a rolling blackout or maybe natural catastrophe.

It is possible to make your own employing store-bought pieces for around 0 and also have it having out enough power to perform all of the above-listed matters. All your whole outcome are going to be just about 16 volts, which can charge a 12v car battery within about four to five hours.

The actual panelare offered ready-made coming from many online stores for approximately -0. What precisely you are considering is actually a 15-16V output and will also cover 26x12 long in space. These are typically roughly 5 w or possibly even longer. With a comparable cost, you can create one on your own and produce it perhaps just a little bigger. You will need ample panels to match a similar voltage and the substances to build a weatherproof parcel with a translucent (glass,plastic-type, etc.)side for the solar cells to be up against sunlight. Unless you're an authentic hardcore do-it-yourself kind, though, this is probably not in your case. It's easy to do something erroneous (crack a solar panel, mis-wire something, not really make the container good enough) and also have the complete thing increase in smoke,requesting near-total new.

To select your panel, you will need a battery. These might be any sort of 6 or 12 volt electric battery. By having six volts,you'll need not less than two so you can match them together to produce 12 volt and you may make use of something more to create any type of series that is certainly 12 volt, and yet capable of having even more electric power. If you intend to make use of this model frequently (every single day), you should pay the extra to get great deep-cycle, gel, or nickel (NiMH) batteries. If you don't, the electric batteries will have a shorter life span and definitely will need replacement in a very short amount of time. You can obtain a fine marine deep cycle battery pack for -0 in lots of shops.

Following that you will require something to place the batteries in. Any kind of robust, non-conductive package will do. Thats usually where you can put in the extra to really make it look great and opt for the decorations or simply have something useful that makes the batteries as one and from the floor. The system really should not be air tight, however, as the batteries will get hot then cool down throughout use and need to breathe a little. Additionally, you will want a chance to function wire connections into and out from the box, of course. Plastic-type milk crates, ancient plastic bins (with no closed lid),wood crates, and so on. Almost all work well.

The electronic devices you'll need to keep on all of this functional and secure can be purchased at any electronics market as well as online. You need a DC meter, an electric controller (a lot of involve a meter), and enough wire in order to connect everything. Your cable must be totally shielded (no bare sides,or even at connections).

Finally, most importantly off, you'll need an inverter. 200-250W is probably sufficient for what this homemade solar panel and battery will probably be competent of setting out. A bigger one isn't going to injure, particularly if you want to improve the model, but in case you receive on every low it will jaunt its fuse all too often working something more challenging than a cigarette lighter.

You can also pass by the inverter altogether and utilize 12v appliances around the system. See truck stops and online trucker sites and you'll find that there are actually countless normal household appliances (crockpots, coffee pots and pans, fans, etc.) that run using 12v power. A number of other things include cigarette lighter plugs for example laptop computers, mobile phones, and so on. Lots who build one of these simple charging systems use it in order to run their gadgets and small home appliances or autos. You are able to charge as well as electric bike, a portable computer, your Mp3 music player, and even more.

Optima Battery - 3 Distinctive Battery Types Capable of Supplying Your Entire Vehicles Power Needs

!±8± Optima Battery - 3 Distinctive Battery Types Capable of Supplying Your Entire Vehicles Power Needs

The majority of vehicles will use a RedTop Optima battery with a strong 5 second starting burst for its primary function of starting a vehicles motor. Immediately after ignition the vehicles alternator will constantly monitor how much charge remains in the RedTop battery and whether or not to provide top up battery recharging power.

Examples of some vehicles which would use this particular battery would be heavy equipment, diesel powered, hot rods, RV and automotive.But what if my vehicle does not have an alternator or requires the use of higher electrical loads?

In this case it would be best to then use a YellowTop Optima battery as it will have a higher discharge cycle compared to the RedTop batteries. Thus making it suitable for drag/racing cars, electric autos, snowploughs, as well as many other aftermarket vehicle accessories such as GPS, chargers, fridges, winches, hydraulics, inverter systems and specialized audio/video installations which require greater than 250 watts more power above that of the vehicles original equipment spec.

I heard that the BlueTop Optima battery should be used for deep cycling applications. This is true for the light greyed BlueTop cases, however there is a distinct difference between the YellowTop and BlueTop deep cycle batteries in that the BlueTop deep cycle batteries have 2 sets of posts - automotive (SAE) and threaded, whilst the YellowTop batteries excluding model D31T only have SAE posts.

An added feature of the dual purpose light greyed BlueTop batteries is that they also have a very high cranking power which makes them suitable for starting applications as well. Examples of where this type of Optima battery is used are with trolling motors and marine/RV applications where excessive electrical energy is required.

It should be noted that if a marine/RV application requires only the use of the starting feature of a BlueTop battery then it would be best to use a BlueTop battery with a dark grey case as it has been specifically manufactured for this purpose alone.

Forget about all the primary colored Optima battery top details, just give me the facts?

Use dark gray casing batteries for starting applications only and light gray cased deep cycle batteries for dual purpose operations.

It is important to remember that a deep cycle application will usually result in discharging a battery between 60% and 70% of its capacity whereas a SLI (starting / lighting / ignition) battery is designed to push out maximum power for a short period discharging between 1% and 3%. It is therefore not advisable to use an SLI battery for deep cycling applications as its battery life will be shortened depending on how regularly it is deep cycled.

DIY Solar Panels For Home, Shop or Farm

!±8± DIY Solar Panels For Home, Shop or Farm

Thanks to modern technology supplying electrical power to remote areas of your farm, or emergency power for your shop or home, is so much easier and more efficient than it used to be. In recent years manufacturers have developed solar cells that will pump out reliable electrical energy for years, and they are now really affordable if you buy them right. The solar cells that are available by just searching the Internet are designed to put out a small amount of electricity when they see the sun, and simply by wiring them together you can produce enough power to run a pump, emergency lighting, fence charger or have the ability to run power tools in remote areas. How about powering heating mats or lamps for chicks or puppies out in the barn?

There are lots of solar panels kits for sale on the Internet, but they have one problem in common; they are too expensive and cost too much to ship. Also, you may not get enough information about how to assemble, install and use the panels once you get them. For small jobs or intermittent duty it only takes a panel big enough to produce 18-24 volts DC, a battery and a small inverter, if you want AC power. A panel of this size uses 36 solar cells or so, and you'll soon find that they can be ordered online for very little cost, and shipping might even be free. The rest of the materials needed to assemble a working solar panel can be bought right down town, so it just doesn't make sense to order a complete kit and pay 3-4 times as much to get a panel that does exactly the same thing.

The fact is you can get everything you need to build your own solar panel for around 0 that will be just as good as one you might order as a kit, and with some good instructions just about anyone who knows how to use basic hand tools can build a panel right in the garage or on the kitchen table, if you prefer. Once you assemble a solar panel the lead wire is attached to a 12V battery; it's best to use a deep cycle type like a marine battery because a standard car battery is not made to be discharged repeatedly like your system will require. Then an inverter is used to pull from the battery power and produce 110 volts AC power to run your tools or appliances, and again you can get one right in town that will work just fine.

If you find that your project requires more power than one solar panel will handle, you can simply build more and wire the solar panels together in parallel to produce more wattage. A nice little system for backup or emergency power can be built for a few hundred dollars instead of a few thousand dollars that pre-made kits will cost, and you will find a DIY solar panel project to be fun and easy.

Boat Alternators

!±8± Boat Alternators

Are they practical or is alternative production of AC power on boats preferable? Generators and shore supply are the main methods of obtaining AC power on board, but there are other methods. You could run a high voltage alternator from the main engine by belt drive, but this is not entirely satisfactory because the alternator needs a constant speed to maintain the correct number of cycles per second. Special drive systems are available which keep the alternator at constant speed when engine speed varies, but the cost of these can only be justified on larger vessels.

Another option to drive an alternator is a hydraulic drive. This system uses a hydraulic pump driven by the main engine, with the alternator driven by a hydraulic motor. This system allows the alternator to be mounted remote from the engine and makes the hydraulic power available for other uses, but in harbour it does mean keeping one of the main engines running to obtain the AC current. It can be a useful system at sea on a motor boat where shore power can be connected when the boat is in harbour.

The other two alternative systems convert power from the battery from DC into AC. This immediately limits their use to power equipment with a comparatively low consumption, otherwise the drain on the battery would be too high. The rotary converter is a unit in which a DC-powered electric motor drives an AC alternator. In practice the motor and generator are combined on the same shaft, sometimes using the same armature to improve efficiency.

Power inverters are solid state appliances which make the conversion from DC to AC electronically. Whilst the power output of a rotary converter is limited only by its size and the tolerance of the battery drain, inverters tend to be more limited in capacity; probably the maximum output you could hope to achieve is around 1 kW, although most are much less.

Neither rotary converter nor power inverters are particularly efficient. Both produce heat which is wasted energy, and the maximum efficiency is likely to be around 80 per cent. This would be achievable with a square wave inverter; a sine wave unit would have a lower efficiency. The low outputs and comparatively low efficiency thus make power inverters suitable only as a temporary means of making AC available, perhaps to power an electric drill or for a television set, but not for any permanent long term use such as powering a refrigerator.

Finally, there are the portable types of marine generators using an air cooled petrol or diesel engine. These are very useful units to have on board, but they do need adequate ventilation, so finding a suitable location where boat generators can be kept dry is not always easy. Most have a plug-in socket for the power output and they can usually produce mains voltage AC or battery charging DC from separate windings on the generator. They are not particularly quiet, and their main purpose is for repair work when using electric tools or for temporary battery charging rather than for constant use.

Obtaining power through any of these alternative systems is not cheap. The low efficiency of power inverters raises the cost of engine generated DC power being used, whilst the fuel costs of a portable petrol-engined charger can be up to ten times the cost of similar power from the mains supply. Even diesel generators can be three or four times the cost of shore power, even without considering the capital costs involved, so the shore cable connection is the option to go for if possible.
