Power Inverter For Home Solar Power System


One of the key components of a home solar power system is the power inverter. The Photovoltaic (PV) cells on the roof will convert the sun energy into Direct Current (DC). The current will then be stored in deep cycle battery.

Since most of our home appliances use Alternate Current (AC), the power inverter will be used to convert the DC to AC.

So how do we choose the best power inverter for our residential solar power system?

If you need some really clean power similar to the type of power you will get from the grid, you will need an inverter which is capable of producing a sine wave with the same characteristics.

Why do you need an inverter which can create similar sine wave from the power grid?

The reason is because you’ll need clean power to effective operate the electrical appliances at home.

Let me explain.

The sine wave from the power grid has very low harmonic distortion. If you are using inductive load such as microwave oven or any devices that use a motor, good sine wave will let it running faster, quieter and cooler. It will also reduce audible and electrical noise on fans, florescent light, amplifier, TV etc.

An inverter capable of matching the sine wave from the grid will let your electrical devices run as if it is getting power from the grid.

The process of setting up the power inverter is actually quite easy. At one end of the device, you will see the terminal that will be connected to the batteries.

Most power inverter will generate heat when converting DC to AC. That’s why, most inverter comes with built in exhaust fans. Make sure there are no obstructions on the fan or it will affect heat dispersion.

On the other end of the inverter, usually there will be a 110 or 120 volt output. This is where you can connect a power outlet extension adapter where your electrical devices can be plugged in. You will also find the on and off switch on the side of the inverter and the grounding point.

The Ugly Truth About Wall Mounted Microwave


Here a tip on fixing air leaks at your house. Do you have a microwave up on a wall or cabinet with a vent that blows air out? Guess what, it is costing you money even when it is not turned on!

How could that happened?

During cold winter days, the warm air in the room is seeping out the vent. The worst thing is, cold air from the outside is being blown into the house through the vent!

To check whether your microwave is an air leak in your house is simple. Get the Black & Decker TLD100 and use it to check the temperature of the microwave and its surrounding area.

Most probably, you will find the surrounding area is much warmer that the microwave. If the temperature difference is very big, you’ll have a problem there. This basically means there is a big gaping hole where the hot air is escaping.

The microwave using a vent that is blowing off all the cooking smoke will come out off one of the vents by the side of your house. The problem is, the vent is not very well insulated. If you were to look closely, it is just a piece of flimsy tin cover.

When there is a strong gasp of wind, the cover will open and letting the cold air into your warm room.

Guess what? You may not be able to feel the cold air coming it, but the thermostat will sense it.

The thermostat will then keep the heater running harder and longer. That is how the wall microwave will cost you money even though it is switched off.

How do you fix this problem?

Sadly, there is not a lot you can do to fix this issue. What you can do is seal all the surrounding area around the microwave to make sure no hot air is getting out and no cold air is getting in.

When you’ve finished with the seal, use the Black & Decker TLD100 again to check the surface temperature.

How To Install Solar Panels On Roof




After you have built the Do It Yourself (DIY) solar panel, the next step is to install it on the roof of your house and start to connect all the components together.

What type of wire should you use for the solar panel?

The type of wire recommended is the BX wire which is really just 12 gauge wire with a wrapping of sturdy aluminum to protect it from the harsh external environment.

BX wires are typically used in household wiring and it is very common in any hardware store. Using a 12 gauge wire is adequate for a small home solar power system.

When wiring the solar panel, remember, the black wire is for the positive run of the solder Photovoltaic (PV) cells. The white wire will be negative and to be connected to the negative run.

Finally, the green wire is the neutral and will be connected to the solar panel and acts at the grounding wire.

To begin the wiring process, start by stripping about an inch off its end. Next, connect the positive and negative run wire from the solar panel to the respective wire on the BX wire.

Use a pair of pliers on the ends and give it a good solid twist on the exposed copper wire. Finish it off by placing a wire nut on the connections.

Here’s a tip. Be very careful when installing the solar panel. Even though it is just producing about 18 volt of electricity, it still can give you a nasty shock. The shock will not kill you but it might just unbalance your footing and cause you to fall off the roof!

The final stage of installing your homemade solar panel is to connect the wire to the charge controller and let it run.
