Ordinary PV systems provide electricity at daytime. Unused energy flows back into the public grid. Electricity in the evening or at night has to be expensively drawn from the grid.

In order to increase their own consumption share, while reducing the cost of electricity, surplus PV energy can be stored in a battery. If not enough PV power is generated, for example,
in the evening or at night, the energy storage is discharged. Depending on the installed PV capacity and battery size a complete autonomy is almost possible.

With the Smart Energy + series our engineers have developed both AC and DC-coupled storage solutions that meet these requirements.

Energy usage PV system with battery storage

In order to increase their own consumption share, while reducing the cost of electricity, surplus PV energy can be stored in a battery. If not enough PV power is generated, for example,
in the evening or at night, the energy storage is discharged. Depending on the installed PV capacity and battery size a complete autonomy is almost possible.

The SmartEnergy + DC systems achieve a high system efficiency thanks to the DC coupled PV generator. In case of an blackout the system remains fully functional and esnures an uninterrupted power supply.

All systems have integrated grid and plant protection (according to VDE AR-N4105). This means you can always decide if you want to feed back your surplus energy or not.

With the SmartEnergy + DC you are ready for the future. Our systems support conventional and new battery technologies. We have created a selection of suitable lead-acid and lithium battery modules for you.

Be always up to date. The SmartEnergy + DC informs you about the current energy flows and status changes via the integrated graphics display, mobile app or free Internet portal.

Be independent and enjoy 100% energy autarky with the new SmartEnergy + DC storage systems.
