Energy Container Solution

Energy Container Solution

The Energy Container Solutions (ECS) are modern battery storage systems that – depending on the application and energy demand – are installed in small 10-foot containers or in several 40-foot containers on a turnkey basis.

The battery storage system connects the power consumer (e.g. a factory) to the public power grid. If necessary, a renewable energy producer such as photovoltaics, wind or hydropower can be integrated into the system.

The ECS stores surplus energy, e.g. from a photovoltaic system, during the day. This surplus energy can then cover the energy demand at times when the sun is not shining (in the evening or at night). The intelligent system control with self-optimising demand analysis software ensures a significant increase in efficiency, safety and sustainability.

The ECS thus provide companies with more flexibility to reduce their electricity bills, but also offer more security should electricity costs rise in the future or even a supply shortage threaten.

Each solution is individual and is precisely tailored to the respective specifications and requirements. Each system has a modular, scalable LiFePO4 battery storage system with corresponding power and control electronics and is provided to the user pre-wired and configured as a ready-to-use solution.

Use Cases


In the event of mains fluctuations, the power supply is supported by drawing energy from the battery storage system, and in the event of a complete mains failure, the entire power supply is switched to battery operation within a maximum of 20 ms.


In off-grid applications, a diesel generator or fuel cell serves as a backup for power needs. This is hybridized by a battery storage system so that it is only operated at full load in phases, thus reducing fuel consumption, maintenance requirements and pollutant emissions while increasing service life, safety and sustainability. In addition, efficiency can be further significantly increased by incorporating renewable energy. Depending on the application and energy requirements, the intelligent system control automatically switches on the gensets through the remote start/stop function.


In most off-grid applications, diesel generators have previously provided the power. By integrating a battery storage system, new or existing gensets are hybridized so that they are only operated at full load in phases, thus reducing fuel consumption, maintenance requirements and pollutant emissions while increasing service life, safety and sustainability. In addition, efficiency can be further significantly increased by incorporating renewable energy. The system control is parameterized specifically to the application in each case, so that the diesel generator is switched on and off at the optimum time by the automatic start/stop function.


Large battery storage systems in the megawatt range can cap peak loads and thus prevent irregularities when feeding electricity into the public grid. In addition, these storage systems protect against grid failures or can, for example, temporarily store energy generated by photovoltaics and thus make it available for use at night. The independence from the forward price on the electricity market can thus significantly reduce electricity costs.


For all applications with high electricity demand, variable size battery storage can be used to reduce costs and optimize self-consumption. In most cases, the additional energy generation by a photovoltaic system is the most widespread solution to reduce the power consumption from the grid due to relatively low acquisition costs. The energy generated during the day is temporarily stored and made usable for the night or for periods with less sunshine. Thanks to their modular design, generators and storage units can be scaled as required and designed precisely to meet the conditions of the application in question. Thus, a power supply from renewable energies of up to 100% can be achieved.


The ever-growing demand for electric vehicles requires the rapid development of a corresponding charging infrastructure. However, since it is difficult to meet the energy demand at peak times by drawing from the public grid, battery storage systems are used as a “boost” to cover peak loads. By releasing the energy previously stored in the batteries, they support the grid power and thus enable fast and trouble-free charging of electric vehicles.


CNHybrid – Technology Integration with Partner Continest

In the CNHybrid, AXSOL combines an intelligent energy generation and storage system with innovative, foldable 20-foot containers from cooperation partner CONTINEST. The CNH owes its versatility to the integrated battery storage. Together with mobile photovoltaic systems and back-up generators, this forms the ideal unit for maximum efficiency and security of supply – in any situation.

The core of the energy generation and storage system is the intelligent system control. This ensures ideal interaction between the electronic components and therefore maximum efficiency in every application.

AXSOL‘s integrated energy systems can be configured to suit any application thanks to their modular design, intelligent system control and a sophisticated installation system. For example, the battery capacity can be configured depending on the application and the output power can be expanded to up to 10 kVA by running several inverters in parallel.
