Who can benefit from a commercial energy storage system?
A commercial energy storage system, also known as an energy storage unit, is ideal for businesses looking to reduce their energy costs in the long term and operate more sustainably. Companies with high energy demands – such as manufacturing firms, agricultural operations, larger office complexes, or charging parks – benefit particularly from this solution. By using a storage system, these businesses can not only reduce their reliance on external suppliers but also significantly lower their carbon footprint.
For effective use with a PV system, it should provide at least 0.8 kWp per 1,000 kWh of annual consumption to ensure sufficient surplus for storage. However, even without a PV system, a commercial energy storage unit is worthwhile: it can be used to make optimal use of dynamic electricity tariffs and to cap peak loads, helping to minimize grid strain and reduce costs.
Commercial energy storage systems therefore offer flexibility, cost efficiency, and promote sustainable energy supply within the business.
Our sustainable battery storage solutions give EV batteries a second life and optimize energy efficiency for industry and commerce.

Frequently Asked Questions
A commercial energy storage system makes your business more independent and sustainably reduces energy costs. With our intelligent energy management system, your consumption is optimized, positively impacting your bottom line and sustainability goals.
No, our storage system also works without a PV system, for example, to utilize dynamic electricity tariffs or as a charging infrastructure for electric vehicles. This way, you stay flexible, regardless of your existing infrastructure.
Yes, the Voltfang 2 is specifically optimized for outdoor use. It is weatherproof and robust, making it ideal for various environments and conditions.
Our storage system uses powerful, safe reused EV batteries (lithium iron phosphate cells). These second-life batteries come from well-known German OEMs and were originally used in electric vehicles or sourced from overproduction. This technology offers the highest levels of safety and durability, making it ideal for reliable energy supply. Compared to new batteries, each 10 kWh can save up to 1 ton of CO2, 3 MWh of energy, and 50 kg of resources, maximizing efficiency and promoting resource conservation.
Our system stores cheaper electricity when tariffs are low and releases it as needed. The intelligent energy management adapts to market prices, maximizing cost efficiency and providing flexible energy use for your business. More information can be found here: dynamic electricity tariffs and commercial energy storage.
