How do I get started with my Sundance portable power station?

Since the Sundance comes pre-wired, set-up is as easy as 1,2,3.

  1. Install a fully charged, lead-acid battery (available at any automotive or big-box store) by connecting the 2 pre-wired 5/16” ring terminals to the battery bolts. Connect the negative bolt first then the positive.
  2. Plug in your solar panel to the quick-disconnect port on the power station.
  3. Plug in whatever you want to operate with solar energy – 110AC, 12VDC or USB.
What type of battery do you suggest?

Your battery box will accommodate a class 24 to class 31-type battery. Also the wattage of your solar panel array will determine the battery size. The more solar wattage, the bigger the battery should be. It’s up to you and your budget, but generally, the bigger the better. The more energy you are able to produce and store, the more amp hours you will have to use.

For our testing we use a group 24, 12v RV/marine deep cycle 101 amp hr battery.

Can I use a lithium or gel battery?

Not with the 30 amp PWM controller. It only handles a deep-cell, lead-acid battery. However, the MPPT 40 amp controllers (and higher amperages) can handle lithium or gel batteries.

How many power outputs will I have?

You will have 6 USB ports, 3 AC outlets and 2 DC receptacles for a total of 11 power outlet options.

What does a solar charge controller do?

A solar charge controller automatically regulates and maintains a safe and balanced flow of energy from the solar panels to the storage battery.

What is the difference between PWM and MPPT charge controllers?

A PWM (pulse width modulation) controller is an electronic switch between the solar panels and the battery. The PWM is a good low-cost option:

  • for smaller systems.
  • where the efficiency of the system is not critical,  e.g. trickle charging.
  • for solar panels with a maximum power voltage of up to 18V for charging a 12V battery.

MPPT (maximum power point tracking) controllers have more electronics inside and are much more complex than PWM controllers. The MPPT is recommended:

  • for multiple panels totaling more than 400W

  • for panel-to-battery distances of more than 50 feet.

  • when the solar array voltage is substantially higher than the battery voltage, e.g. using house panels for charging 12V batteries.

Are solar controllers weather-proof?

No. Neither is the inverter. The power station should be protected from the elements. The solar panels, however, are designed to be waterproof and weather-resistant.

Is there a guarantee with the Sundance Portable power station?

Yes and it’s built into the price. All components of the power box have a two or three year replacement warranty.

How much does the Sundance portable power package weigh?

The shipping weight of the box, controller, inverter, panel and 30-foot cable is about 11 pounds..

Do you test the system?

Every Sundance system is tested in real-life situation in our shop for a week before it’s shipped. This guarantees there will be no surprises for you or us!

Can I add more solar panels to the Sundance power station?

Of course.   All you need is a solar cable “branch connector” that combines the output from the panels to the input port on the box.

Can I connect my Windwalker wind generator to the Sundance power station?

Absolutely you can.  And other brands of wind generators, as well.

Tell me more about the solar cable.

The Sundance package comes with 30 feet of flexible10 awg (American Wire Gauge) stranded, oxygen-free, copper, red/black bonded zip cord cable. True 10 gauge wire (2-conductor, 109 strands per conductor. 0.25 mm per strand.

Each end is terminated with an MC4 connector. This large gauge wire will insure minimum loss of power from your solar panel to the power station.

What if I need more than 30 feet of cable?

Tell us your requirements and we will quote you a price.

What is new about the 250HD?

The newly redesigned Windwalker 250HD has been built with total ruggedness in mind.The new motor housing has walls that are 9mm thick and are literally unbreakable.We guarantee the frame, blades, tail fin, and housing for 3 years. We have also redesigned the tail fin boom so that it can be taken apart for easy storage.

How does the Windwalker connect to the battery?

The generator motor is pre-wired with a 2-way molded connector (quick disconnect). You can simply hardwire the ends to your battery. Red to positive.Black to ground. The in-line connector allows you to quickly separate the generator from the battery when taking it off the mast for storage.

Can my battery get overcharged?

No. Voltage does not overcharge. Too many amps coming in for too long will overcharge a battery. This is simply not possible with a micro turbine such as the Windwalker 250. Think of the Windwalker generator as a “trickle charger” for your battery or battery bank.
.

How long does it take to assemble the Windwalker?

The Windwalker 250 HDcomes with a tail fin and 8 blades that need to be bolted onto the hub. This takes about 20 minutes and uses a 7/16″ wrench.

Why isn’t a mast included in the kit?

To save you excessive shipping costs.The mast is a standard Schedule 40 1” inside diameter galvanized steel threaded pipe that can be purchased at any hardware or home improvement store for about $15. Suggested lengths are 30” and 36”.The mast may be spray-painted according to personal aesthetics. Threaded pipe is necessary only for the mounting plate, but it works for the ladder bracket, as well, and is readily available.

How long does it take to install the Ladder Brackets?

The two female clamps on the ladder have to be measured and squared vertically.Time required is about 30 minutes using a 9/16” wrench which is necessary because the flanged, nylon-insert locking nuts cannot be turned by hand.

How high above the ground will the wind turbine be?

True height above ground will be determined by your rig plus the mast height.

Average height using the ladder brackets with 36” mast is 14 feet.

What are the overall dimensions of the assembled wind generator?

Windwalker 250 is approximately 24” long x 24“ wide (diameter of blades).

What if I want to check the generator’s output?

First disconnect any load (such as the battery).Then connect the +/- probes of a digital multimeter set to DC voltage directly to the output wires of the turbine.While it is spinning, you will get an accurate voltage reading.

When is a battery considered full?

When not being charged or used, a 12V battery is fully charged at about 12.6 to 12.7 volts.

Is the Windwalker 250 HD water resistant?

Yes, the housing is weather resistant but not totally waterproof. To make waterproof simply apply a silicon bead around the motor protrusion.
