Wattage TwinPower
You can have normal 230 V electricity to your cottage without a connection – reliably even in winter.
An integrated system that combines the battery, inverter and backup power into a single, ready-to-use unit. Deployment without design or configuration. No technical adjustment, no monthly fees.
Available as a ready-to-use enclosure solution or as a wall-mounted version depending on the application.
Ready-to-install package - no planning or adjustment
Just lift the device into place, plug it in and get electricity to your cottage without any system design, programming or matching of components.
Works automatically
Charging, backup power and energy management work without user control.
Designed for the Finnish winter
Works and charges even in sub-zero temperatures without any intervention.
Uses standard household appliances
Fridge, coffee machine, lighting and other 230 V appliances as normal.
Quiet and carefree
The aggregate is rarely needed and the system works independently.
How the system works in practice
Fully automatic operation
- Solar panels charge the battery whenever energy is available
- Wattium provides stable 230 V electricity to all appliances
- The aggregate starts only when needed and charges the battery quickly
Everything works automatically without any action by the user.

Example of use
The TwinPower 3000 enables normal cottage use, such as:
- continuous use of the fridge
- lighting and electronics
- a coffee maker and an electric kettle
- microwave and small appliances
- cooking on the stove and in the oven
- the dishwasher is also available with backup power
Batteries and solar panels typically cover daily cottage use without the need for separate energy management.
The aggregate acts as a back-up power source and restores energy quickly when it is needed.
