Mm... I find this for you. http://smarterdeals.info/324771/transfer-card
No its not. Its for 24v security cameras.
The 24v battery is used to provide the initial field current. This couples to the stator windings, and as the generator spins induces a voltage on the stator windings, which causes back EMF onto the field windings (when load is present), which slows the generator's spin until the governor kicks in to bring it back up to speed. The important thing to note is the output power of the generator is not a factor of the 24v field voltage, it is directly dependent upon the fuel being used to get the generator spinning. The 24 volts just "jump starts" the field voltage. Think of it as synonymous with the 12 volt battery that starts your car.
You don't. 2 12v panels together don't make 24v - doesn't work that way. If you need 24v you need to get 24v panels.
To determine the amperage for a 24V 200AH battery, you use the formula: Amperage = Capacity (AH) / Voltage (V) So for a 24V 200AH battery: Amperage = 200AH / 24V = 8.33 amps
Of course it is bad, whether it`s humming or not.
A 24V transformer plug-in typically requires an input voltage of 120V AC and outputs 24V AC. It should be compatible with devices that require a 24V power supply. Make sure to check the wattage and current ratings to ensure compatibility with your device.
Apply 24v and listen for click Ck coil for open with ohmmeter Clean contacts if possible
The recommended voltage requirement for a thermostat compatible with a 24V transformer is 24 volts.

You need a 24v to 12v converter. Truck stops either keep them in stock or can get you one.
You need a DC power supply in order to connect a 24v DC motor to household power.
