I can not power this directly from a dc 12 volt. Do I have to have or use a driver/controller?

You hAve to use a stepper motor driver. The can be picked up from amazon for around 3-5 dollars each. They are controlled by a direction (high/low) sigal and a pulse to in increment the steps.

I don't quite get your question. But I can guess what you want as I just put my WG450A to work. The controller for the wind generator is not included in the package. You need to purchase it separately. The controller has to be one for wind generator (it should be included in the product description). Without the controller, the wind generator is useless. After you get a controller, you would get DC current with variable voltage reading. I did not attempt to use the current to charge a 12V battery. Instead I purchased a grid tie inverter to convert the DC current to 120V AC current and put it back in the grid. I believe it works fine. By the way, the wind generator is a very good one if you are looking for a small wind power generator.

No you have to use the power adapter supplied. Unless you rigged up a 12 volt DC battery near it.

Short answer, yes. Just wire it up like how you would a light bulb; make sure to add a resistor, this thing only take 12volts DC only.

If you want 110 (shore power) you will need an inverter. If you only want DC power you will not need an inverter, just a battery or batteries for 12 volt power.

Voltage setting is Automatic. Connect to battery first so Controller can determine the Charging Voltage. Then connect the PV Panels.We usually use 24V Battery Bank, so I cannot say how well it works on 12V.

depend on what you are hooking it up to. If using as a battery charger than yes you need a controller. If hooking up to grid tie inverter or D C heat element than no do not need a controller.

I also bought this . It only works on a 24 volt dc system. Mine was not advertised to convert from a 12 volt dc source.

instructions say power source is only 120V so I believe you need a converter.

this controller doesn't care if it is 12 or 24 volts,, not very many watts though,, it will take a while to much charge in that battery

Uses a "wall wart" power converter. Just use any generic 9volt DC converter that you have.

The power source is 120 VAC. There is no provision on the device for powering it with DC/Battery.

This is nothing more than a 12 volt dc power supply. Check the voltage and current demands of your application and if they require 12 volts dc and less than 2.5 Amps than it will work. If it is AC or more than 12 volts dc or if it requires more than 2.5 Amps than it will not work.

The music controllers I have purchased did not come with a power supply. You will need a 12v DC source. I have used AC to DC converters to power the controller. You can either purchase one, or use an old laptop or some other charger that outputs 12v DC (you will need to cut and strip the wire to connect it to the positive and negative terminals on the music controller).

You need to buy a 12 volt DC power supply with a mini USB ending you can get it from the same company

Yes, the Inverter should hook directly to the battery, with very large cables. You can run your low wattage dc loads off the Renogy 30 amp charge controller. I run some 12 volt dc lamps off the charge controller. See the diagram on Renogy's web site for an example... Follow the hookup order for the cables to the charge controller

It work with 12V DC safe voltage and have 2 wire. you can connect it to the power supply directly.
