Immersion wattage requirement?

    Hi,

    I'm trying to figure out this idea I have.
    I want to install a wind turbine out the back of my property.
    I posted over in renewable energies but this is more of a technical electrical query.
    What I'm seeking to do is just heat the water in my immersion tank - thats all. Its been suggested to me to sell my power back into the grid, but right now, I have no interest in this.
    I got advice from some wind turbine suppliers and they suggest a battery back set up saying that once I have erected my turbine, I should connect it to Batteries, reccommending 12v battery/s with a minimum capacity of 100amps though 200amps giving me greater storage of power.
    Amps is watts/volts. So if the 12v, 300w turbine was producing 300watts per hour it would charge 25amps of the battery in an hour (300/12 = 25). Therefore a 100amp battery would take 4 hours to charge (or discharge) at 300w per hour. I would get an 8 hour reserve time with a 200amp battery at 300wph. (useful for those hot summer days when theres no wind I'm told)
    From the battery pack, and then to an inverter, I'm told I can then just connect my immersion heater.
    Will this work? I'm no expert in electrics and would be getting a spark to intall properly but I just want to get thoughts here?

    I'm concerned the immersion will have a greater wattage use than the inverter can supply?
