An inverter makes the electricity generated by solar modules usable: It converts direct current into standard household alternating current, optimizes energy yield and monitors the system for safe operation. Depending on the project, we recommend proven inverters from Deye or Victron.
USE OF DEYE INVERTERS
With the Deye inverters in 15 kW and 20 kW power classes, we rely on state-of-the-art technology for maximum efficiency and reliability. As these devices continue to develop, we are always “state of the art.”
USE OF VICTRON INVERTERS
Victron inverters stand for compact performance at the highest level. Thanks to their small size, they are ideal for applications with limited space – for example, on houseboats, ships or in mobile systems. They offer reliable conversion of solar power and are particularly flexible in use.
High efficiency
Maximum energy yield thanks to state-of-the-art MPPT technology.
Flexible to use
Compatible with various storage systems and PV systems.
Reliable & safe
Robust design, integrated protection functions and durable 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.
