Storing photovoltaic energy
Efficient storage solutions for private home
Until recently, owners of photovoltaic systems could only use their solar power generated by day during the day – or alternatively feed the surplus into the grid. With the new storage solutions of renowned manufactures, it’s now possible to store the photovoltaic power during the day and then use it in the evening or at night.
The system first covers the power requirements of the household and then fills the storage system. Only then is surplus power fed into the public grid.
That means that the power generated using photovoltaic panels is saved in home storage systems and then made available for any number of everyday activities. Compared to the direct solar power feed-in system, which is currently very common, this approach offers considerable benefits for the owner.
There’s no reason why you should have to use the power immediately yourself.
The objective of energy storage is to store surplus solar power until you can use it yourself. In practical terms, this requires a time delay: the solar power generated by day (with peak performance at noon) must be made available to meet demands at all times. That means that the surplus energy generated at noon can be stored in the storage system and then used in the evening, and no energy needs to be purchased from the grid.
Incidentally, technical innovations like this one fit in well with the government’s energy concept, as it relieves the strain on the power grid. The solar power is used directly and there’s no need to transport it.
Long service life
A high-quality solar batteryfeatures high cyclic stability, which means it can be charged and drainedvery frequently. Depending on the storage technology, the depth of discharge also has a direct influence on the service life of the solar battery. The full capacity of lithium-ion batteries can be used. Lead-acid batteries on the other hand boast the ideal cost effectiveness with a depth of discharge of 50%.
To ensure you’re able to use as much of the stored solar power as possible, the solar battery should be highly effective. These days, cutting-edge lithium storage systems achieve a level of efficacy of over 95%, which means very little of the stored solar power is lost during the process.
Innovativehome power station for using self-generated electricity
The innovation behind energy storage solutions is a combined solar and battery inverter. The unit is stored in the cellar or a utility or storeroom.
The nearly standardised network of individual measurement, control and output unitsis now a thing of the past
The inverter feeds surplus energy into the public grid, which results in revenue for the owner. The system for private homes and smaller companies is designed for the daily supply with a realistic self-generated power ratio of well over 50%, so that between 65 and 100% of the total self-generated electricity is used at home.
The system is designed for the three-phase supply of private homes and smaller companies with an output range between 5 and 20 kW.
Grid control, all energy measurements, electrical safety and full battery control are integrated into the power module, allowing you to work with any type of battery and control all electric devices from a central location.
Household solar power storage offers the opportunity to break away from the energy market. Energy companies and their power grids experience less strain and are better able to distribute peak loads. Using self-generated power allows greater flexibility and reduces the volume of power fed into the grid.
