Q: I am extremely concerned about Climate Change. Can Solar Power change this?
A: Yes it can! Solar Energy emits no greenhouse emissions into the atmosphere, which is one of the major impacts in relation to Climate Change.
Climate change is a rapidly advancing human crisis that threatens millions of lives, natural species and the environment, according to leading international scientists.
The Intergovernmental Panel on Climate Change – a group of thousands of renowned international scientists who provide authoritative advice on climate change – predicts drastic negative effects if climate change continues at its historic levels, including:
• Increased risk of extinction for up to 30% of the world’s natural species by 2020 and total extinction of 40% of the world’s species by 2080.
• Increased natural disasters – such as flood, wildfire and storms.
• Increased mortality from heat waves, floods and droughts.
• Destruction of coral reefs and melting of polar regions, raising sea levels by 13 to 20 feet.
• Millions of deaths worldwide and enormous increases in poverty and hunger.
Climate change is caused by the build-up of carbon dioxide and other greenhouse gas emissions in the atmosphere. Carbon dioxide is produced by human activities such as employing industrial processes, using fossil fuels as an energy source and destroying forests which assist in removing carbon dioxide from the atmosphere.
To address climate change we must dramatically reduce our greenhouse gases emissions, primarily by moving away from traditional sources of energy to more efficient and renewable sources. This requires understanding and commitment at all levels – including government, business and individuals.
Q: Do I need Modified Sine Wave, or Pure Sine Wave?
A: Advantages of Pure Sine Wave inverters over modified sine wave inverters:
a) Output voltage wave form is pure sine wave with very low harmonic distortion and clean power like utility-supplied electricity.
b) Inductive loads like microwave ovens and motors run faster, quieter and cooler.
c) Reduces audible and electrical noise in fans, fluorescent lights, audio amplifiers, TV, Game consoles, Fax, and answering machines.
d) Prevents crashes in computers, weird print out, and glitches and noise in monitors.
e) Reliably powers the following devices that will normally not work with modified sine wave inverters:
• Laser printers, photocopiers, magneto-optical hard drives
• Certain laptop computers (you should check with your manufacturer)
• Some fluorescent lights with electronic ballasts
• Power tools employing "solid state" power or variable speed control
• Some battery chargers for cordless tools
• Some new furnaces and pellet stoves with microprocessor control
• Digital clocks with radios
• Sewing machines with speed/microprocessor control
• X-10 home automation system
• Medical equipment such as oxygen concentrators
Modified Sine Wave works well for most uses, and is the most common type of inverter on the market, as well as the most economical. Pure Sine Wave inverters (also called True Sine Wave) are more suited for sensitive electrical or electronic items such as laptop computers, stereos, laser printers, certain specialized applications such as medical equipment, a pellet stove with an internal computer, digital clocks, bread makers with multi-stage timers, and variable speed or rechargeable tools (see "Appliance Cautions" below). If you wish to use those items with an inverter, then choose a Pure Sine Wave inverter. If you mostly want to run lights, TV, microwave oven, tools, etc, a Modified Sine Wave inverter is fine for your needs.
We often are asked if computers will work with Modified Sine Wave. It's been our experience that most (with the exception of some laptops) will work (though some monitors will have interference such as lines or a hum). However, if you have any doubt about any appliance, tool or device, particularly laptop computers and medical equipment such as oxygen concentrators, we recommend that you check with its manufacturer to be sure it is compatible with a Modified Sine Wave inverter. If it is not, choose one of our Pure Sine Inverters instead.
The difference between them is the Pure Sine Wave inverter produces a better and cleaner current. They are also considerably more expensive. You might find it practical to get a small Pure Sine Wave inverter for any "special need" you may have, and also a larger Modified Sine Wave inverter for the rest of your applications.
DO NOT plug small appliances into the inverter AC receptacles to directly recharge their nickel-cadmium batteries. Always use the charger provided with that appliance.
DO NOT plug in battery chargers for cordless power tools if the charger carries a warning that dangerous voltages are present at the battery terminals.
Not all fluorescent lamps operate properly with an inverter. If the bulb appears to be too bright, or fails to light, do not use the lamp with an inverter.
Some fans with synchronous motors may slightly increase in speed (RPM) when powered by an inverter. This is not harmful to the fan or to the inverter.
Certain rechargers for small nickel-cadmium batteries can be damaged if plugged into an inverter. In particular, two types of appliances are susceptible to damage:
Small, battery-operated appliances such as flashlights, cordless razors and toothbrushes that can be plugged directly into an AC receptacle to recharge.
Certain battery chargers for battery packs that are used in some cordless hand-tools. Chargers for these tools have a warning label stating that dangerous voltages are present at the battery terminals.
DO NOT use an inverter with the above two types of equipment.
The majority of portable appliances do not have this problem. Most portable appliances use separate transformers or chargers that plug into AC receptacles to supply a low-voltage DC or AC output to the appliance. If the appliance label states that the charger or adapter produces a low-voltage DC or AC output (30 volts or less), there should be no problem powering that charger or adapter.
