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

- 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.

- 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)
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!
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
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
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!
