When you want to focus on the essentials at the cottage
The purpose of the cottage is to relax, be closer to nature and get away from it all.
Electricity makes it easier to stay at the cottage – but only if you don’t have to think about it or monitor it all the time.
Wattium is made so you can focus on the good things about your cottage.
Nature, moments and togetherness – not equipment.

Frequently asked questions
Does Wattium need constant adjustment?
No. The Wattium works automatically and takes care of the production and use of electricity autonomously. The user does not need to monitor the system continuously.
Can you use normal household appliances at the cottage?
Yes. The Wattium produces a standard 230 V AC supply, so you can use the same equipment at the cottage as at home.
Does Wattium also work in winter?
Wattium is designed for northern conditions. The system is made to work even in cold and low sunlight conditions.
Do you always need an aggregate?
No. The aggregate is only used when the sun and the battery are not enough. Most of the time its use is minimal.
Is Wattium suitable for all cottages?
Every cottage is different. That’s why we always recommend a survey before making a decision, so that the solution is correctly sized.
Does Wattium require technical expertise?
No. Wattium is for the user who wants electricity that works without technical knowledge.
