best Solar Energiser for 100-150m kits

Which Solar Energiser is best for a 100-150m kit?

When you’re looking at which solar energiser to purchase for a 100m or 150m electric netting set up the
same basic principles apply – namely where do you live and what are your expectations?

To work out which solar energiser suits your requirements, we need to know when and for how long you
intend to use the energiser as well as how the electric fence fits into your overall flock protection plan. For
example, are you running the energiser 24/7/365 and is it the sole line of defence between your flock and
predation? Or is this just a weekend / hobby thing and the flock is securely locked away every single night?

A quick note on energiser capacity – energisers are measured in โ€œOutput Joulesโ€ (J). A 100m set requires
an energiser with a minimum of 0.5J, 150m around 0.8J etc. You can always put more power than you
need into an electric net but you cannot put less. Another way of looking at this would be to say – regardless
of where you live or what your expectations are, the power level you require remains the same, what
changes is the size of the battery and the solar cell.

Watch this video for an explanation of why Output Joules is the best way to compare energisers or else read on below.

1. Energiser options for 24/7/365 Operators in Southern Australia

The big issue here is that you will need sufficient solar cell wattage to charge the battery all year round –
especially during the winter months. For example, if you live in an area that gets about 4 hours of Sunshine
per day in June (primarily VIC and TAS) then you will need an absolute minimum of a 10W solar cell to get
a 0.5J energiser powering a 100m electric net through the winter (and this would be a marginal case).

(Just a quick diversion here – a solar energiser which comes in one box and all the bits are molded into one
piece is called an โ€œintegratedโ€ energiser. Bigger energisers where you purchase the battery separate from
the energiser separate from the solar cell is called an โ€œexternal batteryโ€ energiser)

So, since you will need a 10W solar cell to get through the winter you are looking at the larger integrated
sets or possibly some of the smaller external battery units. The best value external energiser sets are made by JVA, but if you
would prefer an integrated set then Nemtek, Hotline or Thunderbird are your best options.

If you choose to go with a external battery energiser then you will need to purchase an appropriate deep cycle battery. Which battery you need will depend on exactly where you live and therefore the best thing to do is give us a call if you choose this path. We can either supply you an appropriate battery or you can purchase one from your local battery dealer. The bigger the battery you purchase the longer it will last in poor weather conditions.

2. Energiser options for 24/7/365 Operators in Northern Australia

If you live in an area that gets more than 6 hours of sunshine per day in June (roughly north of the line from
Coffs Harbour to Geraldton) then you can reduce either your solar cell or your battery but not both. You will
need the same size energiser however as you are still powering the same length net.

So the sensible thing here would be to reduce the size of the solar cell and keep the same size battery.

3. Energiser options for Hobby Operators in Southern Australia

For the purposes of this article I am going to assume that a โ€œHobby Operatorโ€ only uses the net in the
warmer months of the year (say September through to April) or locks their flock indoors at night and turns
off the energiser.

The big advantage that โ€œHobby Operatorsโ€ are going to have over the โ€œ24/7/365โ€ crew is that the hobby
operator can turn off the energiser at night during the winter months which effectively doubles battery
capacity. Therefore the integrated sets usually win here due to the ease of use and portability,

You are still going to require an energiser with an output over 0.5J, which means we can look at integrated
sets such as the Thunderbird S90B or the Hotline HLS67.

4. Energiser options fo Hobby Operators in Northern Australia

By and large the same rules apply in Northern Australia for hobby operators. Having the ability to turn the
energiser off at night makes roughly halves the amount of battery or solar cell capacity required so the
integrated kits are usually the best option although any energiser bigger than this will also do quite nicely.

My recommendations.

What I am going to do here is try and make an educated guess and rank all energisers on the market that
fit in the 100m to 150m electric netting sizes. I will rank firstly by capacity, taking note of the solar cell and
battery capacities and then price. All prices are RRP – if you want a quote for a specific net / energiser
combination please contact us for standard pricing.

JVA MB1.5 Electric Fence Energizer with Solar Ki

โ˜… JVA MB1.5 Solar. Puts out a charge of 1.5J which also puts it in the 200m of netting category. This
is a nice simple system with a 20W Solar cell but you will need to supply your own battery. Pair it
with a big battery and the 20W solar cell should be able to get a 100-150m electric net powered
throughout the year in all areas. The main downside is that it has no battery condition lights or a
display to indicate output levels. RRP $339 plus a battery

 

Notes.

1. Donโ€™t just choose the biggest! An energiser with twice the output will also drain the battery twice as
fast. So if your fencing set up requires 0.5J in order to function, choosing an energiser with an
output of 1.0J to 2.5J might make sense but 5J is a bit silly.

2. Choose JVA products if you just want something simple and cost effective. There are no indicator
lights so you should purchase a fence tester at the same time.

3. Nemtek products are for people who want to set up the system to suit their needs. Fully
programmable with separate day / night operations, output levels and pulse rates. Multiple indicator
lights and the works.

4. Thunderbird is best if you just want to take it out of the box and not lug batteries around.
