Consulting
Individual, transparent and tailored to your requirements.
Our consulting is individual, honest and transparent. Together, we analyze your current situation, your energy requirements and your goals. We take into account both technical and economic factors and show you which solution creates the greatest added value for you.
Planning
Detailed calculation and design of your system for maximum economic efficiency.
In the planning phase, we develop a tailor-made concept for your system. We take over the detailed calculation, the dimensioning of the energy storage and the design of all components. The result: a solution that guarantees maximum economic efficiency, efficiency and future security.
Implementation
Professional installation with the highest quality standards.
Our experienced specialists install your system on schedule and to the highest quality standards. Through professional installation, tested materials and precise execution, we ensure that your energy system functions reliably – from the start.
Customer service
Support with the expansion of existing PV systems as well as reliable repair and maintenance.
We are also there for you after the installation. We support you in expanding existing PV systems, take care of maintenance and repair and are at your side as a reliable partner for all questions. This ensures that your system remains permanently efficient and safe in operation.
Our energy storage system is usually installed in a basement, cellar vault, or a
suitable storage room. For maximum safety – especially when multiple
modules are stacked on top of each other – our technicians perform a professional wall mounting.
The modules are delivered by freight forwarder or by our own team. Thanks to integrated rollers, they can be easily moved to the installation site, after which the rollers are removed. Alternatively, the modules can also be safely lifted using the integrated eyelet system. For stacking the energy storage modules, the eyelets can also be removed.
Our energy storage modules utilize particularly safe 48V technology. The installed LiFePO₄ cells are considered extremely reliable and, unlike conventional lithium-ion batteries, cannot self-ignite. This means for you: maximum safety with full performance.
In the front area of the storage system, where the electronics such as the BMS and wiring are located, our engineers have deliberately planned additional space. This ensures good ventilation and protects the components from overheating. At the same time, we remain flexible: In case of future adjustments – for example, due to new legal requirements or new state-of-the-art components – additional components can be easily integrated.
Fundamentally, our energy storage systems are very durable and low-maintenance. However, if a malfunction does occur, the failure is usually attributable to the electronics—specifically the BMS (Battery Management System) or the communication interfaces (RS485 / CAN bus). These components are subjected to greater stress than the actual LiFePO₄ cells, which are extremely robust and long-lasting.
The typical spare part costs per module are approximately:
BMS: €200–250
Communication Board: €250–300
LiFePO₄ Cell Unit: €150–200
Briefly explained:
BMS (Battery Management System): Monitors and protects the cells, ensures uniform charging and discharging.
RS485 / CAN-BUS: Enables communication between the storage system and the inverter and master module.
All components in the energy storage system are securely mounted and thus protected from vibrations. The stable aluminum frame provides additional stability, while the outer casing made of HPL panels offers particularly robust protection.
HPL (High Pressure Laminate) is a high-pressure laminate characterized by its extreme robustness: It is shock- and scratch-resistant, withstands moisture and UV radiation, and is flame-retardant (fire protection class B1). Thus, the internal components are reliably protected against external environmental influences such as heat, moisture, or mechanical stress – and the storage system remains operational long-term.
Thanks to the modular design, maximum operational reliability is thus ensured.
