This diversion controller is the result of our many attempts to use the controllers currently on the market (offered by some of the largest names in the business), to work in conjunction with our wind turbines. None of the other diversion controllers on the market did what we needed a diversion controller to do. So we designed our own and added all of the features that are truly needed in a diversion controller. Comes made to set to 12, 24 or 48 volt.
- Connect multiple turbines and solar panels up to 440 amps worth!
- Use for wind or solar or both at the same time! Also use for hydroelectric or solar or both.
This controller uses the same exact relay as the MW-440 so the amp and watt ratings are the same; this controller is user adjustable, has a large enclosure, microprocessor controlled, test button and battery status indications -- There is no other controller on the market like this one.
Use this controller to regulate and prevent battery overcharge in:
Also works as a Disconnect Controller
This controller works by either diverting the charge source to a diversion or "Dummy" load, or if you prefer, you can simply disconnect the charge source from the battery -- Works either way.
Some of the key features of this controller are:
-Microprocessor controlled -- This is very important for both stability and functionality.
-User changeable settings -- Several controllers on the market set the dump level, and that's that!
-Super High amp rating - 440 Amps -- 10,000 watts. --
-Battery status LED - Several controllers do not tell you what's going on - This one does!
-Push to test. -- Ever wonder if your controller & load are working okay?
-Large (8" x 12") solid steel enclosure, with multiple conduit knockouts
-Large enough terminal blocks that you can actually terminate large wire
-(See notes below.)
-The electronics are fully isolated from the enclosure, no ground loops.
-RJ-11 Serial interface. -- This allows connection to a computer for both programming and remote status (See notes below.)
-Can divert the source from the batteries to the load, or dump both the batteries along with the source.
-Draws almost no energy while monitoring (all electronics must use some power, to work -- this is a miser)
Some specifics about the points made above.
The microprocessor is the heart of the controller. It is given the battery voltage and the user changeable trip points. This information is analyzed and acted upon.
The Battery level is checked, and based on that info, the Green LED flashes or illuminated as follows
1.(One) Flash indicates the battery is less than 12 volts (12 volt system - Double for 24 etc)
2.(Two) Flashes indicates the battery is 12 to 12.5V
3.(Three) Flashes indicates the battery is 12.6 to 13v
4.(Four) Flashes indicate the battery is 13.1 to 13.5V
5.( Five) Flashes indicates the battery is above 13.5V but less than 13.9V (Settings are adjustable)
Steady green means the battery is full.
The red LED is illuminated when the battery is being dumped at 14.5v (or the charge source diverted.)
The dump remains active for a min. of 5 seconds, at which time it is checked by the microprocessor. If battery voltage drops below the "Dump Cancel " level, the dump is disabled, otherwise the dump is continued and rechecked every 5 seconds.
When you click the "TEST" push-button - the 5 second cycle is started (one time, unless the batteries are within the "Dump start" and "Dump Cancel" zone.)
For those who like to get into the heart of the circuits -- We will include both the circuit schematic and the actual program that runs the microprocessor. The Microprocessor is a Picaxe-08M, this is a great little chip that allows almost anyone with a little basic programming ability to learn and use quickly. If you wish to work with the circuit at this level, you need to have the PICAXE software. This software is available from PICAXE (possibly free). You will also need a RJ-11 to Serial cable. Please Note: For the average user, you will not need (nor want) this additional information or these optional items.
Settings are user changeable! By simply turning a simple potentiometer with a small screwdriver, you can quickly adjust the trip point.
If you are a DIY type of person, you can modify the program directly -- it will do whatever you program into it! High amp rating -- 440 Amps! -- 10,000 watts!! -- This is a MONSTER controller.
This controller is capable of handling the input from 166, 60 watt solar panels, or 10, 1000 watt wind turbines, or any combination of the two not to exceed 440 amps, 10,000 watts. This is a lot of control.
The enclosure is heavy gauge, solid steel, ready to mount. -- No plastic, no junk, simple and rugged.
This Hoffman pull box is perfect for terminating larger wire. It has multiple knockouts on each side of the box. The box measures 8.25" x 12". The electronics are fully isolated from the box.
About load diversion.
Several schools of thought on the subject.
1.The source of power (wind turbine, solar panels etc.) -- should remain connected to the batteries while the dump is active.
2.The source should be diverted to the load directly and disconnected from the batteries.
We happen to believe that is far better to leave the wind turbine connected to the batteries at all times. Why? When you remove the battery level voltage from a wind turbine and send its power directly to a load, then it sees for all practical purposes a short circuit (depending on the resistance of the load and lead wires.) This may cause the turbine blades to slow dramatically and in some cases bring it to a halt. This braking action can cause heat build up in the stator if it is repeated every few seconds or so (if the battery is just a little over the top). When you allow the turbine to see the batteries, along with the load, the turbine remains more within its design realm -- always a good thing.
The internal relay is configured to dump the batteries along with the source, but if you desire to disconnect the source from the batteries and send it to the load directly, simply utilize the N/C contacts of the relay as well.
Ready to go. Simple, built to last, right here in the USA.
