Our range of mains energisers includes the most powerful Olli energisers. A mains energiser is a good choice if mains power is available and there is no need for moving the energiser – it can be mounted permanently, for example, to a wall or post.
All Olli energisers come with a 3-year warranty that also covers damages caused by lightning. Olli energisers are made in Finland. We guarantee availability of spare parts for many years to come, for discontinued models as well.
