Charge controller/diversion regulator and other Smart electronics for wind and solar alternative energy systems.

Everybody calls them something different, but if you have a wind turbine, a windmill, a wind generator, or wind turbine generator, then we have something for you. You may know our product by just as many different names like wind turbine charge controller, wind charge controller, wind generator charge controller, turbine charge controller, diversion controller, charge regulator, diversion regulator, or something else. We just call it a charge controller because you can use it with solar and hydro power too!

If you are charging 12 volt batteries then you should be using our charge controller to protect them from overcharging. Our charge controller will redirect charging power to a diversion load when your batteries are full, then automatically re-apply the charging power to your batteries when they are low again. Our charge controller uses a relay to direct the power to your batteries or diversion load so there is no amperage limit! You just use a bigger relay or multiple relays to handle more power! That means that a single charge controller could control multiple wind turbines, multiple solar arrays, or any combination of wind, solar, or hydro power!

It is also very important to always keep a load connected to your wind turbine to prevent the blades from over-speeding. This is known as a diversion load and can be a simple "power dump" or can be something useful like a heating element.

By using a useful load with solar you can do something with the extra solar power once your batteries are full instead of wasting it like most controllers do!

Our New 12V Smart Switch

Our latest addition to our product line is the Smart Switch. This is something that no battery system should be without. A Smart Switch is an on/off switch with battery supervision built in to automatically turn off when the battery voltage gets too low. You only have to forget one time and your batteries could be damaged for good. Don't leave it to chance. The low voltage point can be set to any voltage you like, and can be over-ridden when you must turn something on. Each Smart Switch can control two loads separately and models are available to switch up to 240 amps.


Since the low voltage point is adjustable, there are other possibilities for the Smart Switch too. You could run all non-vital loads with a Smart Switch and set them to switch off when the battery starts to get low. This way, power would be saved for the loads that must run.
