ENERGY GUARD 3.0.
The New, Versatile Power Guardian

Enables intelligent charging from excess photovoltaic production

From households to the largest buildings

Power under full control with
ENELION ENERGY GUARD 3.0

ENELION ENERGY GUARD 3.0 is a device that monitors the energy consumption of the whole building – from a single household to the largest office parks. Based on the power ordered from the energy supplier and the current energy consumption measured by Energy Guard, it is possible to obtain information on how much power can be directed for EV charging. Energy Guard can also be used in a chain of charging stations (parking lots, shopping centres, fleet car parks), which allows the use of the full potential of the energy supplied. The current measurements are taken using measuring coils, which simplifies the installation process.
