Power Inverter Types

DC to AC and Grid Tie Power Inverter Types

How to choose between modified and pure sine wave inverters and plug-in grid tie or wired grid tie power inverters

A DC to AC power inverter allows you to convert the stored power from your battery bank to the tools and appliances you want to operate.  The term “sine wave” refers to the type of power the inverter is producing – typically modified sine wave or pure sine wave.  Missouri Wind and Solar carries a variety of power inverters, but you need to know which unit is the best for your application.

  1. Modified Sine Wave Power Inverter

    Modified Sine Wave Power Inverter

    Click for product details

    • Most common
    • Lower starting price ($$-$$$$)
    • Emits a “blocky” sine wave
    • Primarily used for operating lighting and most power tools
    • May cause static, buzzing, and/or humming when used with electronics
    • Draws more amps to operate (battery power is used more quickly)
    • May reduce the lifespan of large appliances, like refrigerators.
    • Cannot be wired into a wall outlet

  2. Pure Sine Wave Power Inverters

    Pure Sine Wave Inverter

    Click for product details

    • Higher price point ($$-$$$$)
    • Produces a “smooth” power that closely resembles (or is better than) power from the utility grid
    • Primarily used for electronics, such as  laser printers, medical equipment, televisions,  and variable speed power tools and cordless tool battery chargers
    • Draws less amps to operate (battery power lasts longer)
    • Cannot be wired into a wall outlet

  3. Plug-in Grid Tie Power Inverter

    Plug-In Grid Tie Feed Inverter

    Click for product details

    • Inexpensive ($$$)
    • Feeds back into the grid
    • Turns off if the grid power is down
    • Somewhat limited by wattage rating (about 500 watts)
    • Very easy to use, plug and play operation
    • Inverter is plugged into a regular household outlet

  Tips & Things to Remember in DC Amp Meter Wiring:

  • Use a DC amp meter for amp readings
  • Don’t allow incoming power to exceed the rated amperage (or voltage) of your meter – it may break the unit
  • Match the amp rating of the meter to the amp rating of the shunt bar
  • Match the millivolts (mv) of the meter to the millivolt (mv) rating of the shunt bar
  • The two wires between the meter and shunt bar need to be the same length
  • A wind turbine should be connected to a separate meter than the solar panel(s)
  • To test the amps or volts of your wind turbine or solar panel system with a handheld clamp on meter, you must use a DC model

Troubleshooting your DC Meter Issues:

  • If the needle on the meter is a negative reading, switch the sense wires between the meter and shunt bar
  • If the needle on your analog meter is not at zero when there isn’t incoming power, you can calibrate it by turning the screw on the front of the meter
  • If your digital handheld DC meter isn’t giving you an accurate reading, check the batteries in the unit

About DC Volt Meters:

  • The positive and negative inputs are typically not marked on the DC Volt Meter.  If you connect them to your battery and get a negative reading, simply swap the wires.
  • 12 Volt battery systems should use a 15 Volt meter; 48 Volt systems should use a 70-75 Volt meter.

The Air Boss Axial Flux Wind Turbine Generator

The Air Boss Axial Flux Wind Turbine

 

Gary Brown, fabricator and builder, visits our location in Seymour, Missouri to introduce the Air Boss Axial Flux Wind Turbine.

The axial flux wind turbine  has proven to be one of the most reliable type of wind turbine on the market and has been around since the 1970’s. Due to the simplicity of the turbine, the axial flux is perfect for low wind speed areas.

The design for the Air Boss has been in the works for over 7 years to bring a quality product to the market.

The blades of the Air Boss are extremely high quality and measured to precision.  The blades are laminated and pressed under 20 tons of pressure using the same process for manufacturing wooden aircraft blades.  Once assembled, this model will feature a 10 foot diameter rotor.

The turbine also features double powder coated zinc plated plates, making it a salt proof turbine perfect for coastal areas.

The furling tail system responds to specific mile per hour wind speeds in which the tail will furl up, turning the wind turbine to keep it from burning up in high wind.  The tail arm features a “stop” to keep it from hitting the turbine blades.

Missouri Wind and Solar will be carrying the Air Boss Axial Flux Wind Turbine in the near future. Stay tuned for updates and our upcoming detailed installation video!
