A charge controller or regulator is vital for any wind Generator used to charge a battery bank.A typical wind Generator charge controller constantly monitors the battery voltage. If that voltage approaches a set maximum (the float voltage) then the controller turns on a dump load (aka shunt) which dissipates excess power to prevent it from over-charging the batteries.Buy China Cheap price grid tie wind Generator controller and stand alone wind Generator Controller here.

Frequently Asked Questions

  1. QUESTION:
    How to choose charge controller for solar system?
    Is there any specification difference for charge controller I need to look for (Besides amp) while using solar panel of output 24V and 12V. My application are all in 12V.

    • ANSWER:
      Depends on the charge controller. If you are using a PWM or shunt controller, the panel voltage needs to match the battery voltage. So you need a 12V panel and charge controller. Some charge controllers automatically check the voltage and adjust, so they may be listed as 12/24/48V. But the panel needs to be 12V. http://www.altestore.com/store/Charge-Controllers/Solar-Charge-Controllers/PWM-Type-Solar-Charge-Controllers/Morningstar-Charge-Controllers-PWM/Morningstar-SunSaver-SS-10-12V-10A-PWM-Charge-Controller/p798/

      If you are using an MPPT charge controller, most of them will allow a higher voltage PV panel, and will automatically adjust the output for the battery. These tend to be more expensive, but can increase the output of the panel by up to 30%. http://www.altestore.com/store/Charge-Controllers/Solar-Charge-Controllers/MPPT-Solar-Charge-Controllers/Morningstar-MPPT-Solar-Controllers/Morningstar-SunSaver-MPPT-15A-Charge-Controller/p6185/

      And as you mentioned, amps matter. Mutliply the short circuit current (Isc) of the panel by 1.25, that's the lowest current charge controller you should buy.

      Or call the AltE Store and tell us what your panel is, and we'll point you in the right direction.

  2. QUESTION:
    Where can I find an automatic generator controller to charge a battery bank?
    I have a bank of 40 deep cycle batteries for power to my cabin. I want to cahrge these batteries using a 10KW generator. I am looking for a charge controller that will automatically run the generator when charge gets low in the battery bank and shut down the generator when it is fully charged. Any ideas?

    • ANSWER:
      It's called a "charge controller", look up on line.

  3. QUESTION:
    Is a charge controller needed with a 400w wind turbine system with no batteries or just a power inverter?
    I am setting up a wind turbine system that only has a 400w wind turbine. I am going to make it a tie in and will not have a battery system to save power. Do i need a charge controller or is only having the power inverter enough
    yes i meant a grid tie in.

    so i would need to contact my electric company then and ask them what they supply and what i should purchase myself?

    • ANSWER:
      Do you mean grid tie?

      Inverters work with a fixed DC voltage like 12 or 24 volts. The output of your generator will be varying with wind speed, so you need something in between to adjust the voltage driving the inverter.

      You also need something to adjust the inverter frequency, phase, and amplitude to synchronize it with the power companies power line. Usually the power company supplies or specifies this, as well as the inverter.

  4. QUESTION:
    how long should a 360 wireless plug and charge controller take to charge up completely?
    how long should a 360 wireless plug and charge controller take to charge up completely?

    i just bought a used one from a friend and it seems to take an abnormally long time to charge. so i would like to compare it with other peoples estimates of how long it takes to charge.

    • ANSWER:
      If I play and charge it usually takes a few hours at least.

      Then it would usually take around a week or two to become flat again.

  5. QUESTION:
    Why is a charge controller not necessary for a 5 watt solar panel?
    My 5 watt solar panel car battery charger manual states that charge controller is not necessary for panels under 15 watts. I'm trying to understand the physics of why that's the case. Even if my panel is only putting out say 15 volts at 350mA couldn't it eventually overcharge a battery? What if the 5 watt solar panel were connected to a smaller battery, like a 7amp 12v, could it overcharge that battery? BTW, it has a diode to keep the battery voltage from discharging into the solar panel.

    • ANSWER:
      A typical lead-acid battery can safely be "trickle charged" at C/100 rate, where C is the capacity (if you are talking car battery, that is about 50Amp-hours typical). C/100 for a 50Ah battery is 500mA, so 350mA won't hurt it. The trickle-charge just overcomes losses due to battery self-discharge, which is fairly high in lead acid batteries. Your current is also limited by the internal impedance of the solar cell and diode.

      On a small, 7Ah, 12V battery then, yes, you do run the risk of overcharging if you leave your solar panel connected because you will be charging at about C/20.
