- SEA440 - 440
Amp Battery Regulator
Extra heavy duty
continuous duty relay is complimented by Silver alloy
that can handle
millions of cycles at very high amp loads without fusing
together or sticking! -
units like this are impervious to lighting, EMP and static
- "Simple and
ultra-reliable" - "A BULLET PROOF SYSTEM"
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 (+ -
48 Volt Bank - Turns on and
starts dumping power at 54 volts. Turns off at 50 volts (+ -
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
Diversion Load Regulation-
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!
wind turbines or 40 solar panels !
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
An extremely robust unit! No fancy lights,
meters, bells or whistles and therefore draws ZERO power
This controller may look
fiendishly simple but it took 16 years of testing and custom
parts testing in order to make it long
lasting and dependable. Both
computer board and custom relay contacts made from .999 fine
Silver 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!

Versatile raised steel
Measures 10"long by 8" wide
by 3" tall..
Works for all Wind Turbines,
Solar and Hydro.
For all voltages ranges in
multiple battery banks.
No grounded IGBT's - Lighting
strike proof isolation.
100% electrically efficient.
Draws ZERO power while sensing!
- 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.
on battery banks
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.
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
- TWEAKING THE SEA440 FOR
HIGHER CHARGING RANGES -
- If you want your batteries
to cycle at higher voltage levels you can put a 10 to 1000
ohm / one watt resistor 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. (10 to 1000 ohm / one watt
resistors are common Radio-Shack® parts)
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!
GROUPING - Never mix and match batteries in your
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
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!
