Store energy when it is available—use it when it is needed:
With a battery storage system, companies, agricultural businesses, and municipalities increase their self-consumption and independence.
In many businesses, a large portion of the electricity is generated during the day—but not always consumed when it is available. This is where a battery storage system creates balance: It stores excess energy from your photovoltaic system and makes it available again when needed—for instance, during evening hours, when sunlight is weaker, or for peak load reduction.
However, modern storage systems can do more than just optimize self-consumption. Depending on your objectives, storage systems can be used for peak shaving (reduction of power peaks), active load control, electricity trading, or grid services. Whether it's optimizing self-consumption, revenue models, or grid-serving operation—every application requires a customized solution.
Natur Energietechnik develops storage concepts that are technically sophisticated, economically evaluated, and tailored precisely to your operations. Wondering what storage size fits your business or what economic benefits can be achieved? Don't worry—Natur Energietechnik has the answers and the right solution for your energy system.

Why the Forton is interesting for commercial customers
The PowerCore G2 offers high performance in a compact, industrial-grade design. Thanks to its scalability, it is suitable for businesses of various sizes – from commerce and agriculture to municipal applications. In combination with intelligent energy management, it enables peak shaving, self-consumption optimization, and stable integration into existing energy infrastructures.
Is a battery storage system also worth it for businesses and municipalities?
Yes – and often particularly so. A battery storage system lowers energy costs, shaves peak loads, and increases self-consumption. Natur Energietechnik shows how investment and operation pay off economically – today and in the long term.
How can a battery storage system lower my business's energy costs?
By buffering excess solar power and providing it later, it reduces expensive grid electricity procurement. Especially in combination with load management, peak loads can be avoided – which lowers grid fees and electricity costs. Natur Energietechnik calculates the ideal storage size and economic efficiency for you.
What role does a battery storage system play in corporate energy management?
A storage system can be systematically integrated into energy management systems to intelligently control consumption, generation, and storage. This allows self-consumption to be maximized and the load profile to be optimized. Natur Energietechnik offers systems with interfaces to common control solutions such as Loxone or other EMS platforms for this purpose.
Are the high upfront costs of a battery storage system worth it?
Yes — the investment can pay for itself in just a few years through grid fees, peak-shaving savings, and an increased self-consumption rate. Natur Energietechnik calculates individually for you when your storage system will economically pay off.
How much space do I need, and can I expand the storage system later?
The space requirement depends on the capacity and design of the storage system. For many systems, a small area in the technical room or near the connection point of the PV system is sufficient. If space is lacking there, outdoor solutions are a great alternative: weatherproof, container-based systems that can be installed outside the building – for example, in the company yard or next to the transformer station.
Natur Energietechnik plans and installs storage systems tailored precisely to your specific conditions – whether indoors or outdoors, scalable and future-proof.
