The PowerRouter works with PV or wind to decide whether to use self-generated energy straight away, reserve it in battery storage or feed it back to the grid.
The device has an integrated internet connection, allowing performance parameters to be viewed and managed via a web portal.
Steve Everard, head of Rexel Energy Solutions UK, said: “We’re delighted to have partnered with Nedap to offer such an innovative product and are excited to bring battery storage into the domestic renewables market.
“The new universal retrofit unit is perfect for those who have opted for generation of solar from their own system and, as it is compatible with any inverter, it is suitable for a variety of different forms of generation. And, to top it off, a five year guarantee is provided as standard so installers can be sure that the device is designed to last.”
