Missouri Wind and Solar 440 Amp HVA Charge Controller Instructions and Troubleshooting

12/24/48 Volt 440 Amp HVA Charge Controller

Instructions and Troubleshooting
HVA Charge Controller Graphic


Our 440 Amp HVA Charge Controller for use with Wind Turbines, Solar Panels, and/or Hydro Systems is easily one of our most versatile, powerful controllers in our line of equipment.  In our latest YouTube video, Wyatt gives instructions on how to change the different settings and some general troubleshooting tips.

Some of the features of the HVA include:

  • Diversion-Charge Load Controller
  • 440 Amp 12, 24 or 48 volts
  • High contrast LED dual volt/amp meters with on/off switch
  • Built in D/C Breakers
  • Factory wired for both wind and solar
  • 10,000 Watts! 8 x 12 Hoffman Box
  • Reverse polarity protected

Wyatt shows how to change the controller voltage, extended divert mode, and dump point voltage and what isn’t user changeable!


HVA Charge Controller Instructions and Troubleshooting:

  1. The controller typically ships with the voltage jumper pin set in the 24 volt position, but can easily be changed to 12, 24, 48 volt or extended divert mode by removing and replacing the pin in the appropriate position.
  2. The trip point (dump point voltage) is changed by turning the screw head with a small screwdriver and light pressure.
    • Turning the screw counterclockwise will raise the dump point voltage higher
    • Turning the screw clockwise will lower the dump point voltage
  3. Extended divert mode (EDM) can typically be left unset until you are more familiar or comfortable with your system.  EDM basically holds the charge controller in a diversion and disconnect mode for a longer period of time.
  4. The left breaker is for the diversion load while the breaker on the right is for the wind turbine.
    • Manually trip the breaker by pressing the red button on the breaker.
    • Reset the breaker by gently pushing the red arm back up into place until you hear it click.
  5. If the amp and volt meters are set to on and are not displaying:
    • Check the glass fuse in the upper left inside the circuit board, as it may be blown.
    • If the fuse is in good condition but the meter is not displaying at all or is not displaying correctly, turn the unit power to off and remove the back cover of the meter.  Check to see if the long black chip has fallen loose from its pin and replace it if that is the case.  Firmly replace the back cover of the meter.
    • The fuse is 250 volt 2.5 amps
  6. Always have the charge controller hooked up to the batteries and do not connect wind or solar without having the controller connected to the battery bank.
    • If you do not, and the wind turbine or solar panels produce too high a voltage, it will either take out the fuse, or, if the fuse cannot handle the surge in time, it can do serious damage to the circuit board itself.
  7. If you have a disconnect between the charge controller and the batteries,  always disconnect your wind and solar before disconnecting the controller from the batteries.

Wind Turbine Blades: What’s the Difference?

Wind Turbine Generator Blade Types

 

Wind_Turbine Generator Blade Types

With the residential, small scale wind turbine industry growing rapidly over the last decade, many new wind turbine blade sizes, materials, and designs have emerged onto the market. The options may leave you scratching your head so, with the release of our newest wind turbine blade, the Raptor Generation 5™, we thought we’d answer some questions you may have.

 

 

Things to Consider:

Blade Material:

  • Carbon Fiber Composite: extreme durability, rarely suffers from breakage.  Our Raptor G4, Raptor Series Black, and Raptor Generation 5 wind turbine blades are all a carbon fiber composite.
  • Aluminum, aircraft grade: heavy weight, typically laser cut for precision.  Our Falcon Wind Turbine Blades are made from aircraft aluminum.
  • Plastic: breaks easily, suffers from photodegradation (gradual breakdown from UV rays), sharp and potentially hazardous if breakage occurs
  • PVC: brittle in cold weather, breaks easily, extremely dangerous is breakage occurs (we highly recommend you steer clear of these entirely)
  • Wood: commonly used with axial flux wind turbines, laminated and pressed under 20 tons of pressure using the same process for manufacturing wooden aircraft blades

Factors Affecting Startup and Torque:

  • Width: A wider base provides more surface area for start-up.
  • Weight: Heavier blades require more wind for start up but will provide more torque once they are rotating.  Lighter blades will start up in lower wind speeds but will also quit spinning more readily when the wind dies down.
  • Length: Length also plays into surface area and weight in similar ways as blade width and weight.

Takeaway: small blades require high wind speeds to start spinning, that’s why they’re commonly used as sailboat wind turbines. Larger blades require less wind for start up and provide more torque to keep the turbine spinning under a load.

Number of Blades:

  • More blades have more surface area, more weight & torque to keep the rotor spinning when the wind dies down.
  • Smaller blade sets will allow the rotor to spin faster (higher RPMs, less torque).  Once under a load, when the batteries are charging, the blades will actually slow down.

Small 3 blade turbines may take wind speeds of 12 mph* to turn the blades whereas our 7 blade Freedom wind turbines have start up speeds of 7 mph*.

(*Based on tower height and wind turbine placement)

Odd versus even number of blades:

On even blade sets: when the bottom blade passes the wind turbine mounting pole it creates a disturbance in the blade directly across from it, causing the blades to vibrate and shake.  It’s nearly impossible to get these blades to balance.  Balance is important to minimize vibration in the turbine.

Odd blades: the bottom and top blades don’t align and create a disparity that causes the turbine act as a flywheel to keep the turbine spinning.

 

I highly recommend watching our Wind Turbines for the Beginner How To Part One for more in depth explanations from Jeff on blade basics.

How To: Cut Your Electric Bill – Home Efficiency Check

How To: Cut Your Electric Bill

Home Efficiency Check

Home Efficiency Check

 

Do you know how energy efficient your home is?  Did you know that some appliances are using electricity (and costing you money) even when they’re switched off?  How do you figure out which items in your home are an energy hog?  Watch Jeff’s How To: Cut Your Electric Bill – Home Efficiency Check video – the first in the series.

 

 

 

 

Quick Tips:

  1. Switch to water saving shower heads to save hot water.  Sure, you’ll save on the amount of water you use, but you’ll also be saving on the cost of running your water heater (and your well pump, if you have one).  This quick switch is a no-brainer with multiple energy savings benefits.
  2. Lightbulbs – we all know that fluorescent lights are significantly more energy efficient than incandescent varieties, but LEDs are even better! While compact fluorescent bulbs are 75% more efficient than incandescents, LED bulbs are 85% more efficient and have nearly double the life expectancy of fluorescents.  Bonus: many LED lights come with a 5 year manufacturer warranty for material and workmanship.
  3. Winter insulation on your windows doesn’t have to block sunlight.  Mist a window with a water filled spray bottle and apply a trimmed section of bubble wrap to the window, no adhesives or tape necessary.  This is a simple tip that’s easy to put up and take down.  If you’re not a fan of the look, reserve this hack for seldom used rooms at the back of your house or consider using cold blocking thermal curtains.
  4. Believe it or not, plugged-in appliances continue to consume energy when they are turned off.  This is often referred to as “ghost energy” and the cost really adds up.  Coffee pots, microwaves, DVD players, and other electronics that have timers, lights, clocks built in may be pulling energy even when they’re switched off.  Luckily, many Energy Star models have energy saving options to turn those feature off.  If you’re not sure, we recommend the Kill A Watt device – just plug it into a wall outlet and plug the appliance into the meter.  It does the calculating for you.  If you’ve got “ghost energy” running up your meter, install a power strip with an on/off strip that can be switched off when the item is not in use.
  5. Moist air holds heat better.  Implementing a humidifier in your home during the dry winter months will help hold the heat in the air meaning less on time for your in home heat system.
  6. Did you know ceiling fans will rotate in two directions?  If you can’t remember which is which, you can note “S” for Summer and “W” for Winter on the switch and set a calendar reminder to  change the direction seasonally.
  • During winter heating, to help move warm air that is trapped on the ceiling, blades should turn ‘forward’ in a clockwise motion. This movement will push up the air and pull the warm trapped air down the sides of the room improving heat distribution.
  • During hot summer weather, to help produce a comfortable breeze or ‘windchill’ that cools the skin, blades should rotate in a ‘reverse’ counter-clockwise motion. The air movement has the same comfortable effect as when you fan yourself with a magazine to get relief from hot, stifling air.

Ceiling fans in themselves do not heat or cool a room, but the ceiling fan rotation allows improved air circulation, which can greatly improve the comfort of your living space.  You can also save in energy costs when the ceiling fan is on the correct setting to support your cooling or heating efforts.

How To: Cut Your Electric Bill – Saving Water

How To: Cut Your Electric Bill

Saving Water with SinkPositive

Save Water with Missouri Wind and Solar

 

Jeff shares a quick money and water saving tip using an innovative product.  The employee restroom in our store is cramped on size, leaving the sink and toilet in different rooms.  We recently discovered Sink Positive, a retrofit for your toilet lid that turns it into a sink, delivering a clean, environmentally friendly, and touch-free hand wash with every flush.  Talk about a really convenient space saving product, especially when there isn’t room for a full sized sink!

 

 

Items needed:

  • SinkPositive Standard model (*Missouri Wind and Solar is not sponsored by, or paid by the manufacturer to use or review this product.)

 Installation:

By following the instructions included with the SinkPositive, your sink can be easily installed in just 10 minutes.

 

How to Save Water

You may be wondering how this item will save you money in the long run.

The SinkPositive reroutes clean water from the supply line, the water runs through the faucet for a touch-free hand wash and then drains directly into the bowl. The reuse of this soapy water to refill the bowl helps in saving gallons of water each day, up to 2 gallons per person per day, as well as promoting hygiene.

This product is not for everyone, but offers a solution for where standard sinks are not  an option.

Other ways to save water around the home:

Take showers instead of baths.  A full bathtub can use up to 70 gallons of water.

Turn off the faucet while you brush your teeth to save up to 4 gallons per minute.

Use WaterSense® labeled showerheads to save up to 750 gallons per month.

Test your toilet once a year for leaks.

Install water-saving aerators on all of your faucets.

If your dishwasher is new, cut back on rinsing. Newer models clean more thoroughly than older ones, just make sure you scrape the plates and clean the food trap in the dishwasher.

Drop tissues in the trash instead of flushing them and save water every time.

Plug the sink instead of running the water to rinse your razor and save up to 300 gallons a month.

Washing dark clothes in cold water saves water and energy, and helps your clothes retain their color.

Use the garbage disposal sparingly. Instead, compost vegetable food waste and save gallons every time.
