Olli 122B is the most versatile battery energiser in the Olli family

Olli 122B is a conveniently movable 12V/230V energiser for medium length fences. It can also be connected to mains power with the adapter included. If necessary, the backup batteries (4×1.5V) maintain energiser functionality while the battery is being charged. A solar panel is available as an accessory (Olli 20 W solar panel package). The energiser is supplied with an earthing spike.

The smart energiser automatically chooses the best available energy source. All three power supplies (mains adapter, 12V rechargeable battery, 4 pcs. 1.5V D/LR20 alkaline batteries) can be connected at the same time. The unit primarily operates on 12V battery power, and when the mains adapter (or optional solar panel) is connected, the battery is charged. When the rechargeable battery runs out, the unit switches to the batteries. When the batteries run out, the operation is continued using the 12V battery at low power and slowed pulse frequency.

1.21J output energy. 2 power levels + 2 pulse speeds, the power can also be set to adjust for the light level. Comprehensive LED display. The low voltage warning light indicates the need to charge the battery and low fence voltage warning reveals problems with fence condition. Deep battery discharge protection.

Tip! We recommend using leisure batteries as the energiser’s power source instead of vehicle starter batteries. Read more about using different types of batteries with energisers >

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 >
