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.

HEATER ELEMENTS
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!
