The feed-in tariff for solar energy reduces and the price of electricity increases. Customers wish to become more independent from the grid and protect themselves from electricity price rises. Nedap’s PowerRouter Solar Battery for self-use, the leading storage based inverter, provides the perfect solution to optimize the use of self-generated solar energy. Use the generated solar energy directly, store the energy in batteries for use at a later time, or feed the energy back to the grid. The PowerRouter is the ideal solution for the use of self-generated solar power (self-use).
The energy consumption in most households occurs in the evening, while most solar energy is generated during the day. The PowerRouter provides the ideal self-use solution. The PowerRouter gets more out of self-generated solar energy by storing excess power in batteries for later use. The more self-generated energy you use yourself (optimization of up to 70%), the less dependent you are on the grid and rising energy prices.

With the unique features of the PowerRouter you can take self-use to the next level and use the self-generated solar energy at the time you need it the most.
- Generated solar energy is sent to the PowerRouter
- Use the solar energy directly in your home
- The energy is stored in batteries for later use
- When no solar energy is available the energy from the batteries is used for local use
- When there is a surplus of solar energy, this will be fed into the grid
- Through the web portal myPowerRouter.com you can monitor and manage the energy consumption
- Connect & Grow - Want to start small, before installing batteries? Start with the PowerRouter Solar Inverter, monitor your energy consumption through myPowerRouter.com and expand with the PowerRouter Battery Manager when the time is right. This connect & grow capability makes the PowerRouter unique in its kind and makes it possible to start small and add storage of solar energy at a later time.
- Load management – switch on additional loads. By means of applying an external relay it is now possible to manage and switch on additional selected loads (fig. 3) when there is a surplus of solar energy. For example, a water heater or boiler can be prepared and switched on. In this way the use of self-generated energy can be further maximized.

- Self-use with backup - As any grid-tied inverter, the PowerRouter needs to comply with the local requirements for grid connection. As a safety precaution the inverter is required to disconnect from the grid when the grid fails (anti-island protection). This results in loss of revenues and having no access to the self-generated energy, while solar energy is available. The PowerRouter with connected batteries comes with a unique feature that enables to supply backup power in the event of grid failure. This gives a greater independence from the grid.

- Consumption monitoring - With the PowerRouter, system owners can easily monitor their generated solar energy in the web portal myPowerRouter.com (fig. 4). Besides energy production, it is also possible to get information about the total energy consumption. This means a system owner knows exactly how much solar energy is being produced, how much solar energy is being consumed and how much electricity is consumed from the grid. In this way consumption monitoring gives detailed insight into the system owner’s energy balance.
