Introduction
Congratulations on your choice of a JVA Energizer. In choosing to
purchase the JVA brand you have opted for the highest quality in electric
fencing. Please read this manual entirely before installing your new
energizer.
All JVA products offer a three-year warranty against faulty components
and workmanship but excludes environmental extremes (i.e. lightning,
flood damage, etc.) or malicious damage to the unit or faulty application.
Consumable components (i.e. batteries) are also not covered by the
warranty agreement. To ensure your eligibility for this warranty program,
please retain your proof of purchase.
DANGER! Risk of Shock!
High voltages exist inside the electric fence energizer and on the
fence terminals.

1 Important notes –PLEASE READ
1.1 Electric Fences
1. Electric fences are not toys; do not let children play with them.
2. Electric fences should only be installed with regard to the relevant
Standards and work place health and safety requirements.
3. Electric fences should be signed. Warning signs that comply to IEC
standards should be prominently displayed on electric fences at
distances specified by the country in which they are installed.
4. Electric fences must have an ‘earth’. An electric fence ground is one
or more pieces of metal (eg. 1.8m Galvanized earth rods) driven into
the earth to a depth of at least 1.2m. Three earthing rods are
recommended for customers purchasing the MB8, MB12, or MB16.
Additional earth connections may be required at the energizer or
along the fence in poor soil conditions.
1.2 Energizers
1. The energizer places a very short, safe, high voltage pulse on the
fence live wires approximately once every second. Please be advised
that there is always a risk associated with any device designed to
impart an electric shock. Do not allow children or elderly persons to
touch the energizer or fence live wires.
2. The maximum length of fence able to be energised depends on many
factors, for example the earth resistance, number and spacing of
wires on the fence, type/quality of insulators, resistance of wire,
whether the wiring configuration is series or parallel etc. The amount
of grass or shrubbery touching the wires also alters the performance.
Fence circuit layout is very important. Another factor to consider is
acceptable fence voltage, for some stock situations this is 3kV others
require more or less. Therefore the rated mileage of fence that the
energizer will power effectively is a guide only.
3. DANGER! The Energizer should never be operated with the cover
removed as high voltages exist inside the enclosure while operating.
High voltage may remain on some internal parts long after the unit has
been switched off.
1.3 Power Supply Options
The JVA MB series of electric fence energizers can be powered from a
range of power sources.
•12 or 24V external battery (not supplied)
•12 or 24V external battery with solar panel (not supplied)
•110/240Vac via power pack (supplied with MB models only)
The JVA SV series of electric fence energizers are fully self contained
solar powered energizers. Each energizer in the SV series comes with an
internal battery, integrated battery charger, solar panel bracket and solar
panel.

1.3.1 IMPORTANT NOTES
•Always ensure adequate ventilation is given to the external 12 volt
battery. Lead Acid batteries may emit explosive gases while
charging!
•Always mount the power supply either indoors or undercover.
1.4 Auto-SyncTM
Auto-SyncTM is a new method of synchronising electric fence energizers
patented by Pakton Developments Pty Ltd.
Auto-sync detects when something or someone touches the wires from
two different electric fences, and synchronises the output pulses so that
the potentially dangerous condition of receiving more than one pulse per
second is avoided.
The magnitude and frequency of the electric fence pulse is restricted by
safety standards such as IEC60335.2.76. This limitation is specifically
intended to ensure that a shock received from the energizer (and hence
the fence) is safe for humans. An important part of the safety requirement
is that the person receives no more than one shock per second. When
the pulses are one second or more apart, the human body treats them as
separate events and the heart is unaffected. Receiving more than one
pulse per second can interrupt the natural rhythm of the heart.
Although international safety standards require a 2.5 metre gap between
live wires powered from two different unsynchronised energizers, through
neglect or ignorance this is often not adhered to. For example live wires
running down both sides of farm dividing fences are a common site in
rural Australia.
An energizer running our patented Auto-SyncTM technology can
synchronise with any brand of energizer provided that energizer conforms
to international standards regarding pulse timing.
If synchronisation cannot be achieved or is lost, the energizer will not shut
down. It will continue to operate as though no foreign signal were present
on the fence (i.e. its regular pulse frequency and energy output).
1.5 Solar Panels
1. Mount solar powered energizers so that the solar panel is facing
the noon sun (due north in the Southern hemisphere, due south in
the Northern hemisphere, and at an angle of degree latitude plus
10 degrees). If in doubt, confirm with an online solar panel angle
calculator.
2. Solar panels need as much direct sunlight as possible, preferably
full sun all day. Unlike small solar powered items such as

6
calculators, all JVA solar-powered energizers need direct
sunlight to generate enough electricity to charge the battery.
3. The solar panel also needs to be clean to operate properly. Clean
off any dust or dirt using a damp cloth.
1.6 Rechargeable Batteries
1. The SV5/SV10 contains a rechargeable sealed lead acid (SLA)
battery, while other JVA MB energizers are compatible with lead
acid batteries. SLA battery life is shortened considerably if it is
a) left in a discharged state or;
b) exposed to high temperatures.
2. When not in use store the solar energizer in such a way as to allow
the panel to get as much light as possible, say on a window sill
with the panel facing out. Take the unit out into sunlight for a few
hours once every month to keep the battery from self discharging.
3. WARNING
SLA batteries can produce hydrogen. The energizer case is
designed to release hydrogen gas to prevent an explosion. Do not
take steps to further seal the case. Return the unit for repair if the
O-ring seal has become damaged.
1.7 Other
1. Keep the SV5/SV10 from being immersed in water and out of
extreme heat.
2. Be aware that thieves target solar powered items, so a padlock
may be useful in securing the SV5/SV10 to a fence post.

•Battery life maximization works by slowing the frequency of high voltage pulses just before the
battery dies to keep the energizer going for as long as possible without damaging the battery.
•The over discharge battery protection will stop the energizer when the battery is flat and flash the
status LED twice each second. This stops too much charge being pulled from the battery and
prevents permanent damage. The energizer will automatically restart once the battery voltage
returns to a normal level.
•The reverse battery protection protects the energizer from damage in the event you are having a
bad day and connect the external battery the wrong way around.
•The MB series of energizers seals the electronics inside a durable UV Stable case to protect
from ants, moisture and dust to maximise reliability.
•Overload indication warns you if your fence is heavily loaded by flashing a warning LED and
alerting you with a short audible beep.
•The MB series utilizes the latest digital microcontroller technology to extend battery life, provide
useful feedback on the energizer status, and increase reliability and performance.
•The audible alarm will sound in the event of a serious error for 30 seconds and then shut down for 7
minutes before sounding again.
•The Auto Recover feature will attempt to recover the energizer from severe errors which causes the
energizer to stop working. This automatic recovery process will occur at 7 minute intervals.
•Our patented Auto-SyncTM technology to help keep your fences safe.
•Power on demand automatically increases the power to heavy fence loads.
^To use with a solar panel, an external 12 volt sealed lead acid battery, solar panel and solar
regulator are required (not supplied with this kit).

~Current drain rating is for a 12.5V power source. Current drain will vary
with voltage.
^Recommended solar panel sizes based on the number of sun hours/day
a region receives. To find the minimum number of sun hours/day your
region receives contact your local meteorological authorities.
*The recommended battery size will allow the energizer to operate for up
