Portable Inverter Generators

With one formula, you can find what fan is right for your home. This is the formula for fan CFM: Cubic feet per minute, more commonly known as CFM is calculated by the following formula: air speed (feet per minute) X area (square feet)=CFM. Not everyone is going to take a look at CFM, but for those who do it is a helpful tool. In simpler words than that of the formula, it is the amount of air a fan moves.

Portable Inverter Generators

The amount of air depends on some other factors as well, such as the diameter and shape of the blades, speed at which the blades turn (revolutions per minute or rpm), horsepower (hp) of the motor, and overall fan design. These combined factors establish the air moving capacity of a fan. Fan capacity is measured in terms of the cubic feet, and again, this is how CFM (cubic feet per minute is determined.)

CFM and RPM are the two most important things to look for in a fan, so that you are guaranteed correct and effective operation. If you only know the RPM, and not the CFM, or vice versa, you should feel confident in your fan purchase. As long as you know one of the calculations, you are ensured of a well-working fan. However, if you are not satisfied with these calculations, this is not the only criteria one can use for evaluating fan performance.

One of the main qualifications, second to rpm and CFM measurement is noise level or decibel rating, followed by the next qualification of vibration. Look for fan noise levels rated in sones or decibels. Check these if the CFM or RPM still leave you unsettled about your fan choice.

A standard measurement of airflow indicates how many cubic feet of air passes by a stationary point in one minute. The higher the number, the more air is being forced through the system. The volumetric flow rate of a liquid or gas in cubic feet per minute equals the CFM, and one CFM equals approximately 2 liters per second.

Fan manufacturers base their measurements on a standard measurement with clean, dry air at a density of 0.075 pounds mass per cubic foot, barometric pressure at sea level of 29.92 inches of mercury, and a temperature of 70°F. These standard measurements are used to determine SCFM: Standard Cubic Feet Per Minute.

With the use of CFM and RPM, you can make a more educated choice when choosing your home ceiling, exhaust, or table fan, and know what you are getting!

Fan Calculations – Measure Airflow with CFM

We’d always heard how great it was having a new house, so when we finally got ours, we expected big things. Unfortunately we had no choice but to move in even though there was a lot of work not done. We had no air conditioning in the August heat, no running water, and our only potty was at the gas station down the road. We were hot, exhausted, and grouchy.

So what does this story have to do with a beeping smoke alarm? Everything, as you will soon see. We worked through the days only to throw our sweaty bodies in bed each night. The only bed we’d been able to dig from the pile in our garage was full-sized and nothing like the king we were used to, but at least we had a bed.

I went to bed that night thinking I’d fall asleep immediately. But, I was very hot and the bed was small, and I couldn’t get to sleep for quite awhile. I don’t think I’d been sleeping any length of time until I was awakened by a beeeep! What? Back to sleep. Beeeep! What’s going on? My husband opened one eye and mumbled, “What’s your problem?” He’s unable to hear high-pitched sounds, so he’s unimpressed with my plight. Beeeep! He’s already back asleep, and several beeps later, I manage to join him.

In the morning (Beeeep!) I’m finally cognizant enough to realize what’s going on. It has to be a smoke alarm. But what the heck? They were just installed brand new. They worked fine yesterday. Beeeep! My husband has no interest in tracking the beep down, but I bug him until he goes and digs out a ladder. A heavy 10′ ladder. It’s the only way he can reach our tray ceilings.

Beeeep!

He drags it from smoke alarm to smoke alarm, but all the batteries are fine. After slamming the last one back together in disgust, he climbs down. Beeeep! A thought strikes him. What if he loosened one of the batteries while slamming it back in? Beeeep! So, he hauls the ladder around again.

Our carpenter comes bounding in. My tactful husband says, “What’d you guys do to the smoke alarms? Something’s beeping.” Beeeep! “Kinda dirty around here,” the man observes helpfully. “Maybe one of the connections is dirty.”

Silently, shoulders slumping, my husband gathers up paper towels, cleaner, and his trusty ladder, and makes the rounds for the third time, cleaning the connections. He climbs down for the final time. Beeeep! The carpenter says, “Maybe an alarm just needs reset.” I could tell my husband was ready to punch him, but instead he quietly makes another round. Beeeep!

The carpenter slaps his forehead in disgust. “Now I remember,” he says. “The electric dude said he thought maybe there was a short somewhere.” Face red, but still silent, my husband picks up the ladder and goes to the garage. Beeeep! He climbs up through the hole to the attic, and starts crawling resolutely through the hot dusty space in search of smoke alarms. Of course, he finds a loose connection on the very last one. But at least now there’s silence!

No Fire, But Why Is The Smoke Alarm Beeping?

Where can you get plans to build this generator? Do you want to see videos and testimonials?

Overunity Generator – What is it? – Generate Free Electricity

When you are setting up a new house or building one crucial aspect is to set up your utility suppliers and particularly power suppliers. This means getting gas and electricity for you home, and without these your house will be very much lacking as a home and most businesses won’t be able to operate. Almost all of the luxuries and appliances we are used to today require gas or electricity to use, and this means that we need them for cooking meals – using the hob, the oven or the microwave, for working – using the computer, for leisure – using games consoles, televisions, music players, for heating and even for washing. A home without gas or electricity then would be a home that was cold and empty and that left you resorting to reading books by candlelight – romantic for one night in a power cut but not a situation most of us would be happy to live with.

Portable Inverter Generators

When you set up your power supply this will involve being connected to a power grid to get your energy directed to your home. When you do this you will need to decide if you want electricity and gas, or just electricity. Gas is not fully necessary as most gas appliances can also run on electricity – for example yo can have electric heating and electric hobs. However it is not possible to get just gas (or at least not advisable) as you won’t be able to run things such as computers off of gas. Setting up just one utility as opposed to two makes things simpler and reduces the number of different direct debits coming out of your accounts, however at the same time if you get gas heating you will be using a more energy efficient way of heating your property and will be able to avoid spending more than necessary as a result. Gas heating for example is considerably cheaper than electric heating.

When you set up both gas and electricity you will normally do so using the same suppliers. Normally when you apply to the local grid you will do so for both electrical and gas supplies and they will talk it through with you. If you have bought the home from a site developer, or have bought it from someone else then the building will likely already be connected to a grid and getting a power supply will simply involve choosing an electricity supplier and setting up an account with them. If the building already has a power supply then you need to contact the suppliers to let them know if you’ve moved in. If you want to change to a different supplier you will need to tell them that you want to cancel and then set up a new account. It’s crucial when you move in to take note of the electricity and gas meter readings to ensure that you aren’t paying for any previous residents’ electricity use.

However when supplying a completely new building with electricity you will need a company that’s not only able to supply gas and electricity but also one that is licensed to connect. To do this you will need to look at authorized utility infrastructure in your area. A quick Google search will bring up your options and you can then compare quotes to get the cheapest installation.

Connect Power Or Electricity Supply For New Homes

Top 3 Solar Portable Electricity Generators

Electricity is an invention that has changed the lives of everyone in the world. Starting in the home, electricity has many uses. If one finds that their electricity is not working, then they may want to invest in some lighting parts or lighting supplies to fix their lamps. Lamps are useful because if you have it on then you can see in the dark. Electricity can heat a whole house instead of people depending on burning wood or coal for heat. Because of electricity, people can be comfortable in their home in the winter time. Electricity heats air and then proceeds to blast it through a labyrinth of pipes and passages then warm air emerges from vents that are placed strategically throughout one’s house. Air conditioning is also fueled by electricity and works in the same way but has the opposite effect rather than adding warmth to the home, the air conditioning make it cool and is often used during the summer months.

Portable Inverter Generators

Electricity is used in food preparation in most modern households. Ovens can be used to cook a variety of things including casseroles, cookies, meat, fish, cupcakes, and even sausages. Most ovens have the option of choosing the temperature that one want to cook something at. There is also usually a timer so that one can time the meal or treat that they are cooking. Microwaves are an invention that uses electricity and cooks smaller things in a much quicker time. One can make pasta, hot drinks, soup, eggs, and broccoli in a microwave. One can even reheat a previous meal and eat it as leftovers. Popcorn is a popular microwave treat. Refrigerators also use electricity and they work to keep food cool and fresh so that its shelf life can be longer. This allows people to go to the grocery store less since they can save more food.

Television is more of a form of entertainment but it uses electricity as well. Many people watch T.V. shows and often have a favorite. There are thousands of channels and there is something to watch for everyone. If one does not want to watch a channel, then they can watch a DVD. There are movies that fall under every genre and every interest topic. One can even purchase movies from cable channels if they do not have any DVD’s. Things such as an Xbox, a Wii, and a game cube are gaming systems that plug into T.V.’s. People can play all kinds of games and fitness activities on these devices. They are especially popular with elementary to high school age boys.

There are all sorts of smaller household gadgets that people use that need electricity to work. Alarm clocks are used by many people in order to wake up in the morning. Many women use a curling iron, hot rollers and blow dryers in order to style their hair. Clocks, lamps, and stereos are also popular. Computers also use electricity and are probably the most popular device in the world. Printers also run on electricity.

The Many Uses Of Electricity In The Home

Electrical Wire

Portable Inverter Generators

There is all different types of electrical wiring for different applications. We will break it down for you piece by piece. Most common terms for copper electrical wire would be building wire, THHN /THWN, Romex wire, UF-B Cable and Type SE (service entrance cable). All of these copper wires and cables have their own advantages and disadvantages based on the individual wiring application. Each one will be described in more detail below. Building Wire is just another broad term used in the same way as electrical wire. Since it’s used mostly in the building / construction field its become a popular term.

THHN / THWN Wire

THHN / THWN-2 copper electrical wire is the most basic form of electrical wire which is used in houses, buildings and control circuits not exceeding 600 Volts. All of our THHN electrical wire is dual rated with THWN-2 because the THWN is so popular that South Wire (Largest Electrical wire manufacturer in the USA) decided to put both ratings on all their THHN building wire. It’s composed of soft drawn bare copper strands, covered with a PVC (Polyvinyl Chloride) insulation and a nylon coating for easy installation in cable tray. The 18 awg through 10 awg come in stranded or solid copper. The stranded wire is more flexible, while the solid wire is easier to run / snake through tough areas.

More specifically, THHN wire is run through houses and buildings to light switches, electrical outlets and light fixtures. The smaller gauge sizes of THHN is most commonly sold in 500′ spools which a lot of suppliers won’t cut. WesBell Electronics will cut the #18 – #10 to 100′ spools and cut the #8 – 1000 mcm per foot! That’s right, you can buy 1 foot of wire if needed! WesBell understands that every application is different and doesn’t want contractors to have to suffer excess copper wire. When adding that into the the resale price it could cost you the job! Buy exact lengths, get exact quotes and don’t have any extra copper at the end of it! Copper has jumped back up to over .00/lb, so every foot of wire counts!

Romex Wire

Romex copper electrical wires and cables are made up of multiple THHN / THWN wires (conductors). Example; Romex 12/2 is 2 THHN wires and a bare uninsulated ground wire covered with an overall PVC jacket. This way electrical contractors only have to run one bulk wire instead of either running 3 separate wires or individually running each wire. Romex wire is ONLY used for indoor applications. It has NO protection against moisture, gas or solvents. It should NOT be used outdoors even if it’s in cable tray.

UF-B Cable

UF-B (Underground Feeder) copper electrical wires and cables are a slight upgrade from Romex wiring. It has the same concept of THHN conductors wrapped with a jacket except it’s a more complex jacket. The bonus to UF-B Cable is that it can go outdoors and even directly underground. There’s no need for conduit or cable tray and the price difference isn’t that significant. If you need the cable to go outdoors at all make sure you get UF-B instead of Romex because it’s not worth the hassle of replacing the Romex down the road over something roughly 10-15% higher in cost.

Service Entrance Cable Type SE

Sometimes you will see an “R” (SER) or a “U” (SEU) after the Type SE. The R stands for round (more common) and the U stands for flat. Southwire Type SE electrical cable, service entrance cable is primarily used to convey power from the service drop to the meter base and from the meter base to the distribution panel board; however, the cable may be used in all applications where Type SE cable is permitted. SER may be used in wet or dry locations at temperatures not to exceed 90°C. Voltage rating is 600 volts. Southwire Type SE cable is constructed with sunlight resistant Type XHHW-2 conductors or Type THHN/THWN conductors.

Copper conductors are annealed (soft) copper. Cable assembly plus reinforcement tape are jacketed with sunlight resistant gray polyvinyl chloride (PVC). Available as 1 conductor with a concentric ground, 2 conductor with a round or concentric ground, or 3 conductor with a bare ground. SE cable is jacketed with gray sunlight resistant polyvinyl chloride (PVC).

Differences Between THHN Wire UF-B and Service Entrance Cable

Most of us do not know the importance of electricity until it’s not available. Power cuts are not predictable, it could occur at any moment. Electricity plays an important role in all sorts of business. Especially in hospitals power cuts could create lot of problems. So, whenever there is power cut, the generator could prevent the loss. Generator is a machine that converts mechanical energy into electrical energy.

Portable Inverter Generators

Generally, generators have two main components.

1. Motor: Burns fuel (LPG, petrol or diesel) to supply power.

2. Generator head: Turns the power into electricity. The electricity generated by a generator is measured in terms of voltage and watts.

There are two basic types of generators. They are

- STANDBY GENERATORS: These are used to offset the harmful effects of power failures; they are installed permanently as an emergency power source for your business. They are hard wired into an electric system with special circuitry that detects an outage and then automatically switches over to the standby power supply.

- PORTABLE GENERATORS: These are usually used in places where there is no power from the local power company. These are sufficient for lighting and running appliances and they are less expensive.

Other types of generators, based on the fuel types are gas, LPG, diesel and natural gas generators.

Purchase of generators (buying considerations): After determining the size, there are several things that have to be kept in mind before making out any purchase. Fuel choices, motor speeds and cooling systems should be taken into consideration while making out a purchase. While purchasing, you should know the specific voltage needed for your company, and then you can pick the model that supplies enough wattage. In general, generator employs automatic voltage regulation to prevent voltage spikes from damage, has a displaced phase excitation to maximize starting capability and provide more surge power. Like any motor, a generator motor creates quite a bit of heat and needs a cooling system to prevent overheating. It can be either air-cooled or liquid-cooled. The major difference is that air-cooled systems are louder and but not effective. Liquid- cooled systems are quiet, more dependable and are more expensive to purchase and to maintain. While choosing, look for the one that comes with a brand name motor, because it will be much easier to find the parts and service for a well-established brand.

Maintenance: Generators should also be maintained like other equipments. Large standby types will automatically start each week and power up to make sure whether everything is functioning properly. Smaller generators require manual intervention like replacing the oil and spark plug at regular intervals ensures a proper functioning.

Uses: Generators are used for a variety of purposes, issues, emergencies, situations and events. Places that do not have electric service at all may need generators, the most common examples are construction and camping sites. Hospitals especially need top-notch electric power backup systems.

Generator – An Emergency Power Source

A power inverter converts DC (Direct Current) power from your solar or wind charged battery into AC (Alternating Current). Anything that plugs into a wall outlet in your home runs on AC.

Portable Inverter Generators

RV (Recreational Vehicle) power inverters are designed for use with RV mounted solar panels. Having an RV solar power system is like having a mini onboard power plant. It allows you the freedom and flexibility to camp out where there is no conventional power source; what’s commonly known as living off the grid.

The key to portable solar powered success is investing in a properly sized power inverter. As with everything else, when you purchase an RV power inverter you get what you pay for.

A well made power inverter should be efficient at all input levels, rugged enough to stand up to changing environments and won’t overheat while providing the power to run your small appliances.

Various brand name inverters include Outback, Magnum, Xantrex and Go Power. Choosing and installing a properly sized inverter is a task best left to your local RV professional or alternative energy store.

In order to pick out an RV inverter perfectly suited to your needs, you will have to provide your local professional with some basic information.

You need to know what appliances are going to be powered with the system, how much power they

consume (amp/hours), and the phantom load.

Phantom load is the electricity consumed by an appliance when it is turned off. Your television set is one example, but the worst offender is that cube shaped transformer used to charge cell phones. These transformers are 60% to 80% inefficient and should be unplugged when not in use.

The power consumption of each appliance is stated somewhere on the appliance itself, and is expressed in terms of AC watts or AC amps. What the RV owner really needs to know is the equivalent in DC amps, since that’s what the battery bank is supplying.

Where an appliance’s power consumption is expressed in terms of AC watts, one can use a simple formula to calculate the equivalent power expressed in DC amps:

DC Amps = AC Watts / 12 volts

Example: A TV set with a 100 (AC) watt rating used for one hour would consume 9.17 DC amps.

Look for an inverter with three distinct charging rates: a bulk charge at 100 amps; then dropping to a lesser rate as the voltage increases in the battery bank; and finally applying a float charge just sufficient to maintain the batteries in a fully charged condition. The result is much faster recharging of the batteries, either from shore power or from the motor home or tow vehicle alternator.

A good quality solar panel can deliver approximately 3 amps of power during daylight hours. A conservative estimate for sunny weather might be 6 hours of full solar power per day and somewhat more during summer months. Thus one panel would put roughly 18 amps back into the batteries; 2 panels 36 amps; and 3 panels 52 amps.

The remote monitor and control mechanism mounted inside the coach performs a wide range of functions pertaining to both the inverter and charger functions. It also has the basic “on/off” switch for the inverter.

When “on”, the control panel provides information about whether the unit is operating in inverter or charger mode. If operating in the inverter mode it will tell you the present level of amps being consumed and the present voltage under that load.

If in the charger mode, it shows the present level of the amps in, along with the voltage at which it is being charged along with various warning functions pertaining to overheating and overloads.

Clearly this is not a “one size fits all” choice. Especially important is the need to consider your RV lifestyle when determining whether or not an inverter would be a useful resource.
