Some top-of-the-line audio gear is protected by SCRs or Triacs. These devices are installed to guard against power line spikes, surges, and trash. However, they see the sharp corners on modified sine wave as trash and will sometimes commit electrical hara-kiri to prevent that nasty power from reaching the delicate innards. Some are even smart enough to refuse to eat any of that ill-shaped power, and will not power up. The only sure cure for this is a digital or pure sine wave inverter. 

Computers run happily on modified sine wave but better on pure sines.  The first thing the computer does with the incoming AC power is to run it through an internal power supply. We've had a few reports of the power supply being just a bit noisier on modified sine, but no real problems. Running your prize family-heirloom computer off an inverter will not be a problem. What can be a problem is large start-up power surges. If your computer is running off the same household inverter as the water pump, power tools, and microwave, you're going to have trouble. When a large motor, like a skill saw, is starting, it will momentarily pull the AC system voltage way down. This can cause computer crashes. The fix is a small, separate inverter that only runs your computer system. It can be connected to the same household battery pack, and have a dedicated outlet or two.

Most variable-speed ceiling fans will buzz on modified sine wave current. They work fine, but the noise is annoying. Invest in a pure sine.

All inverters broadcast radio static when operating. Most of this interference is on the AM radio band. Do not plug your radio into the inverter and expect to listen to the ball game; you'll have to use a battery powered radio and be some distance away from the inverter. This is occasionally a problem with TV interference when inexpensive TVs and smaller inexpensive inverters are used together. Distance helps. Put the TV at least 15 feet from the inverter. Twisting the inverter input cables may also limit their broadcast power.

A phantom load isn't something that lurks in your basement with a half-mask, but it's close kin. Many modern appliances remain partially on when they appear to be turned off. That's a phantom load. Any appliance that can be powered up with a button on a remote control must remain partially on and listening to receive the "on" signal. Most TVs and audio gear these days are phantom loads. Anything with a clock—VCRs, coffee makers, microwave ovens, or bedside radio-clocks—uses a small amount of power all the time.

Customers frequently ask us about the use of inverters for medical equipment.  Unless specifically noted in the regulatory approvals for the product, assume that no AIMS inverter has regulatory approval for use with medical devices or life support equipment.  If you use a AIMS Power Inc. inverters with a medical device it’s at your own risk.

Wind Turbine Generator Blade Power Calculator

1. The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of electricity all the time. There will be times when they produce no electricity at all.

2. Many people feel that the countryside should be left untouched, without these large structures being built. The landscape should left in its natural form for everyone to enjoy.

3. Wind turbines are noisy. Each one can generate the same level of noise as a family car travelling at 70 mph.

4. Many people see large wind turbines as unsightly structures and not pleasant or interesting to look at. They disfigure the countryside and are generally ugly.

5. When wind turbines are being manufactured some pollution is produced. Therefore wind power does produce some pollution.

6. Large wind farms are needed to provide entire communities with enough electricity. For example, the largest single turbine available today can only provide enough electricity for 475 homes, when running at full capacity. How many would be needed for a town of 100 000 people?
