 The Wind Turbine PWM Dump Load Controller
Control Your Dump Load with PWM!
Simple, easy way to variably control your dump load

  • More Usable Power - Varies the load to get you more power
  • Needs No Charge Controller - This is the charge controller!
  • User Adjustable Set Voltage - Set it to come on at a voltage you pick
  • CPU Controlled - Microprocessor controlled for set point, timing and PWM
  • Easy Install - Two wires in and two wires out!

pic solar wind GTI controller Simple operation, the special programmed CPU starts to regulate the turbine's speed at a set voltage (typically set to 28.8V or 57.6V) and keeps loading the turbine more and more till it slows down and the voltage comes down.

Keeps energy flowing in lighter winds so you can produce more energy from your turbine.

Picture this: Your inverter is on and running a load and the turbine is cranking out watts, why stop it completely? Why not REGULATE IT instead?

Does not slam on the dump load, uses a gradual method to slow the turbine, saving power. The turbine doesn't have to spin back up, it's being SPEED REGULATED.

Works with wind turbines using a 24V or 48V battery bank.

Up to a 1500W turbine (for a 48V system, see specs), recommended dump load +25% of maximum turbine output.

User adjustable voltage set point.

pic Eaton disconnect box Fits in this recommended Eaton low cost UL Listed electrical disconnect box available at Lowes or Home Depot (not included). You get a disconnect switch, wire connection terminals and a nice enclosure with no extra shipping charges!

No moving parts (such as a fan), it works quietly and efficiently day in and day out without maintenance hassles.

This device comes as a partly assembled kit. The circuit is fully assembled and tested and comes mounted on it's metal heat sink which is designed to fit perfectly in the Eaton box.

Buy a Eaton box from Lowes, Home Depot or a local Electrical Supply house, buy some plywood, mount it & wire the unit. No soldering required.

A 30A ATC Fuse and Fuse Holder are included.

The box and plywood are not included in the kit.

A ready to go box is available from us, if you don't mind paying the extra shipping or don't have a Home Depot nearby, check our other items on eBay or contact us.

pic electrical boxes You can buy a more expensive UL Listed electrical box on the web, your choice. The bigger the box, the bigger the heat sink but the Eaton box is sufficient for max rated amps.
See our [ Other Enclosures Page ] for more info.

You will now own something of substance and value instead of throwing money year after year into the power company black hole!

Reduce your carbon footprint now! Reduce reliance on foreign oil!
