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.
Built around a solenoid that
we have tested (tortured) in-house at over 460 amps, 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, well other than our own C440 of course.
Use this controller to regulate and prevent battery overcharge in:
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, up to 10,000 watts. -- Uses the same relay as the SEA-440.
Works directly with 12, 24 or 48 volt systems. -- The relay contacts can handle open collector voltages of up to 120 volts.
Contrast LED battery voltage. - Several controllers do not
tell you what's going on - This one does!
Contrast LED turbine amperage meter -- Measures 3 digits to the left of the decimal, 2 digits to the right.
Meters can be shut using the on/off switch.
Two factory installed, fully wired D/C breakers and disconnects.
Entire unit is wired and ready to go for both wind and solar.
Battery status LED
Push to test. -- Ever wonder if your controller & load are working OK?
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.
Draws almost no energy while monitoring (all electronics must use some power, to work -- this is a miser)
Reverse Polarity protected.
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 is illuminated as follows
(One) Flash indicates the battery is less than 12 volts (12 volt system - Double for 24 etc)
(Two) Flashes indicates the battery is 12 to 12.5V
(Three) Flashes indicates the battery is 12.6 to 13v
(Four) Flashes indicate the battery is 13.1 to 13.5V
( 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 minimum 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.)
Settings are user changeable! By simply turning a simple potentiometer with a small screwdriver, you can quickly adjust the trip point.
controller is capable of handling ten, 1000 watt wind turbines, or up
to 125 Amps of continuous solar power, or both at the same time. Note:
440 amps is not continuous, but is limited to 20% duty time.
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.
The source of power (wind turbine, solar panels etc.) -- should remain connected to the batteries while the dump is active.
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. We'll be happy to send you a diagram -- this is a very simple to accomplish.
How to compare this controller to others on ebay (or anywhere!)
Can they handle 48 volt systems directly?
Do they have battery status
Do they show you the the current flow from your turbine?
Do they have multiple, pre-installed, pre-wired circuit breakers?
Do the meters have an on/off switch?
Do they have a dump active indication?
Are the dump levels user changeable?
Are they microprocessor controlled?
Do they come with a enclosure that's actually ready to use?
Do they handle the amperage you need?
Do they have a dump test capability?
Are they reverse polarity protected?
When you compare this controller to the others, you will see why we built it and why we know you'll love it.

Since many of us often don't want to take a chance on something from a smaller business, and tend to think that big named products are always better. I thought it might help to pass on some of the feedback from those who have purchased this controller in the last couple of weeks.
PERFECT ! DIVERSION CONTROLLER IS PERFECT ! WISH I COULD GIVE HIGHER RATING !
A very good packaged product.The instructions are an easy read.
As advertised good e-bayer
Item as described, fast shipping
Great Seller! FAST Shipping! A+++
Great product. Got everything working great! Thanks!
ITEM ARRIVED VERY QUICKLY, VERY WELL PACKAGED, RECOMMENDED SELLER
We burnt out two (x-brands) 40 amp models with a 20 amp wind generator, so we knew it was time to solve the problem and create something that could actually do the job. That's what this controller is all about; simple compared to the big brand names, but perfectly in tune with it's mission, save the batteries and keep the turbine spinning.
More to come: Put us on your watch list, we are currently working on a series of new products specifically for the solar/wind market.
Big things are happening from a lot of little companies, and if you notice the truly innovate products are being released from the new kids on the block.
In addition to standard credit card verification procedures which
insure the credit card is not stolen, we also verify the computer
IP address, phone numbers, etc., to ensure the person placing the
order is not doing so for fraudulent purposes. We work with all applicable
agencies to prevent and/or report fraudulent or suspicious activity.
