440 AMP CONTROLLER
10,000 WATT Rated
Battery Over-Charge Controller
Works on all 12, 24, 36 or 48 volt sectional battery banks.
 
The proper place to put a battery overcharge prevention regulator is 'AT THE BATTERY'
 
Can be used to control both large and even the smallest wind & solar systems.
Effectively keeps batteries from over charging by diverting or cutting power.
 
Worlds Lowest Cost 440 AMP Wind & Solar Controller -

 

 
First controller that can divert or simply disconnect
incoming power without an electrical arc occurring -
During wind storms solidstate IGBT controllers can fry!
 
This unit can control up to 10,000 Watts!
That's 12 wind turbines or 40 solar panels!
 
POWER DRAW DYNAMICS:
If you use it as a DIVERSION or DUMP load MODE then it uses no power when it is NOT dumping (energy effecint sensing)
In DISCONNECT mode it draws 2 amps but that's good since that means you have to much power in your batteries anyhow.
 
Used to prevent battery over charging on / Wind - Solar - Hydro
A battery regulator diverts excess power to power some other useful device when ever your battery is full.
Use this excess power to make free hot water or to recharge an auxiliary battery bank, so many uses, just to many to mention!
 
Regulate your BATTERY instead of your wind turbine, solar panels and many other AE devices.
 
An extremely robust unit! No fancy lights, meters, bells or
whistles and therefore draws ZERO power while sensing!
 
 
This controller may look fiendishly simple but it took 16 years of labor and custom parts testing in order to make it long
lasting and dependable. Both computer board and custom relay contacts made from Silver alloy and are built to take over 500 Million cycles or about
85 years of switching for the average system. TESTED for 16 years and proven 100% durable!
15 year warranty on relay - If you can burn it out we will replace it free!!! Full 440 amps at 12 volts / 220 amps at 24 volts / 110 amps at 48 volts

Versatile! Regulates all 12, 24, or 48 volt sectional battery banks (Built for battery bank build out of smaller sections)
Requires only 12 volts to give a representative reading of your whole battery bank no matter how large in size it is!
 
 
The modern way to monitor your battery from over charging is to have a diversion load that performs another task such as heating water when your battery is in danger of over charging. Shutting down the output of your wind turbine or your other renewable energy devices is old school thinking. Now-a-days most people dump their excess power into some other legitimate device optimizing their energy independence. Hot water from your excess power can be used for radiant heating in the winter or even in the hot summer months for washing cloths or dishes and for bathing. You will always find a need for hot water in your life.
 
Our wind turbines do not have charge controllers inside the PMA. Our philosophy is to keep all the electronics easily accessible at ground level and as close to the battery or grid feeder as possible. Raising and lowering turbines is not a fun job so you'll want to put as few components as possible on the top of your tower. Having a charge controller on the top of your tower is very inconvenient to adjust, monitor and to repair or service to say the least!
 

Work great on battery banks built up from many smaller batteries! It only requires to read (sense) the voltage

across any 12 volt power point in order to regulate any voltage battery bank! 6, 12, 24, 36, 48 and 60 volt.

Works for all 12, 24, 36, 48 and 60 volt battery banks by simply sampling power from the

12 volt section and mathematically derives the total voltage of the entire battery bank.

 
Model #SEA440 Tech-Notes:
 
Cycle Characteristics:
12 Volt Bank - Turns on and starts dumping power at 13.50 volts. Turns off at 12.5 volts (+ - 5%)
24 Volt Bank - Turns on and starts dumping power at 27 volts. Turns off at 25 volts (+ - 5%)
48 Volt Bank - Turns on and starts dumping power at 54 volts. Turns off at 50 volts (+ - 5%)
 
 
The +or- 5% variance is caused by differences in diversion load size verses battery bank size.
Many factors can come into play depending on your systems size, load and the age of the batteries.
 
Novice notes:
A maximum charged 12 volt L.A. battery is 15 + volts and not 12 volts
A maximum charged 24 volt L.A. battery is 30 + volts and not 24 volts
A maximum charged 48 volt L.A. battery is 60 + volts and not 48 volts
 
 
SEA440 - 440 Amp Battery Regulator -
Our extra heavy duty continuous duty relay is complimented by Silver alloy internal contacts
that can handle millions of cycles at very high amp loads without fusing together or sticking!
Since our high amperage silver contacts are electro-mechanical they are 100% electronically isolated!
"Electro-mechanical units like this are impervious to lighting strikes, EMP and static electrical discharges"
"Simple and ultra-reliable" - "A BULLET PROOF SYSTEM"

TWEAKING THE SEA440 FOR HIGHER CHARGING RANGES - If you want your batteries to cycle at higher voltage
levels you can put a 1000 to 50,000 ohm / one watt rated potentiometer in line with the green sensor wire and trick the SEA440 into higher
voltage / charging ranges. This may take a little experimentation to choose the right resistor to get the cycle style you need
but it is an effective and simple way to make the SEA440 perform versatile applications.
One watt potentiometers are common Radio-Shack® parts

Questions and Answers
 
Q. - I DO NOT REALLY HAVE A USE FOR HOT WATER. WHAT ELSE CAN I USE MY DUMP LOAD POWER FOR?
A - Many people with cabins like to use ordinary 12 volt automotive head lamps and put them around the cabin. This way the lights
turn on and off all night long keeping both four legged and the "two legged" animals away giving the impression that someone is at home.
 
 
Our inexpensive voltage/dump load regulator will work on 12, 24 and 48 volt systems by slaving off of only one 12 volt battery section. Make hot water, run lights, fans, heaters and other useful appliances once your batteries are full. Can also be used just to "CUT" or disconnect incoming power too. The #SEA440 very versatile unit.

Other ideas for diversion loads
 
 
Micro car heaters are available at many automotive supply stores. These little 150 Watt heaters plug right into your lighter socket. They make great little diversion loads for home use. If you have a 12 volt battery system you can wire up as many as 12 of these in parallel. Most of them we have seen are 12 volt only so if you have a 48 volt battery bank then you can simply put 4 of them in series. They can be placed all around your home or cabin. Perfect little room heaters and very inexpensive.

Trouble shooting:
 
It is VERY important that the slave sensor leads are NEVER to be exposed to the direct high frequency voltage of
the wind turbine or PMA when NOT electrically tied down to a battery in the full circuit! The Red and Green wires
are ONLY to be placed directly on your battery and NEVER directly to ONLY a wind turbine or PMA!
 
BATTERY AGE - Old batteries with dirty or corroded terminals can cause many sensing problems for the SEA440.
Clean the terminals with a wire brush until they shine brightly! Reconnect and enjoy your new found dependability!
 
BATTERY GROUPING - Never mix and match batteries in your bank!!!!!!!!!!! ALL batteries in your battery bank must be of the same type and size but they especially must be the same age!!!!! Having an old, mismatched or shorted battery in the group causes extreme havoc!!!!!!!!
 
BATTERY DISCHARGING TO LOW - If your dump load is very small batteries tend to drain deeper. The simple solution is to use a diversion load that pulls more amperage.
Larger loads tell the controller to turn off earlier in the load diversion load cycle leaving the batteries topped off a little higher.
 
LOAD - If the load exceeds 440 amps the relay contacts may fuse (weld) together. The result will be a drained battery.
We highly recommend you install a 440 amp fuse inline with the power LOOP to prevent this.
 
Make sure all connections are clean and tight before wind or solar power is put into the battery and regulator. Make contact with the battery at all times!
