Olli 300 – basic energiser for shorter fences, medium power level

Olli 300 is a clever, basic mains energiser best suitable for slightly shorter fences. The medium-level 2.8J output energy is quite sufficient in case of animals that respect fences. Typically, this energiser is used with horse and cattle fences, for example.

Tip! Inadequate earthing is the most common cause of poor fence efficiency. By correct and adequate installation of earthing from the very beginning, you can avoid a lot of problems related to poor fence efficiency. Read more about functional implementation of earthing >

Peace of mind for years – Olli energiser service

All Olli energisers come with a 3-year warranty that also covers damages caused by lightning. Olli energisers made in Finland are serviced by the service outlet of our plant and by authorised Olli Service Partners throughout Finland. We guarantee availability of spare parts for many years to come, for discontinued models as well.

Product information

Maximum voltage Indicates the peak impulse voltage in case of a short, leak-free fence (low load) or without a fence. Because energiser voltages are quite high, the values are often expressed in kilovolts (kV), i.e., in thousands of volts.
9,000V
Voltage at 500 Ohm load Indicates the peak impulse voltage if the fence is heavily loaded.
3,700V
Stored energy The maximum energy that the energiser can build up for a shock.
3.8J
Maximum shock energy
2.8J
Power consumption Indicates the maximum actual electricity consumption. In case of a mains energiser, 10W power in round-the-clock use means an annual consumption of 87.6kWh. At a price of €0.15/kWh, using the energiser would cost about €13 a year. A battery energiser is powered from a battery. In many models, power consumption varies depending on the energiser’s power setting and/or fence load. The maximum battery life (in hours, h) can be estimated by dividing the declared capacity of the battery (e.g., 60Ah = 60,000mAh) by the energiser’s declared power consumption: 60,000mAh/100mA = 600h = 25 days.
4W
Indicative number of earthing rods Recommended quantity for the energiser in question. Instead of a single figure, it is indicated as a range, for example, 1-3 pcs., since in dry soil, more earthing rods are required as compared to moist soil. The same applies in case of a more powerful energiser and longer fence.
1-2 pcs.
Maximum theoretical fence length The longest theoretical single-wire fence built of thick metal wire in which the fence voltage can still be sufficient for fence functionality. Indicated in kilometres. In practice, such a situation is truly rare, almost impossible. Nevertheless, alike maximum output energy, the value is useful, for example, when comparing energiser models from different manufacturers.
