Everything from a single source
Electrical planning, control cabinet construction, programming and software come from one team. This saves interfaces, coordination effort and time.

For energy producers, industry, plant engineering & project developers
Control cabinet construction, automation, software and project planning for energy systems. Individually designed, built in-house and commissioned.
Whether electricity utilisation, heat recovery or classic automation: we develop technical solutions where standard products reach their limits. This ranges from our own control cabinets and connections to control systems through to individual heating concepts.
We draw on the same know-how that our product portfolio is built on: electrical planning, control cabinet construction to EN 61439, PLC programming and our own control software. We build anything from one-offs to small series.
We plan, build and commission. For the hydraulics, we bring in licensed installation partners and coordinate the entire project.

From the first idea to the finished system: our services can be booked individually or combined as a complete package.

Planning and construction of control cabinets to EN 61439, including distribution boards, power units, load management and control cabinets. This also covers PLC programming, visualisation, HMI and connections to control systems. We also extend or modernise existing controls without replacing the entire system. Manufacturing, wiring, installation and commissioning take place in-house; handover comes with a test report and complete technical documentation.
Development of control software for energy systems. This includes energy management, dynamic load control within seconds, and monitoring, dashboards and reporting. Connections run via Modbus, MQTT, REST, OCPP, SunSpec as well as inverter, storage, control system and ERP interfaces. Remote maintenance and over-the-air updates are included; where standard products do not fit, we develop custom software.
Technical and economic design of energy systems, from optimising self-consumption and peak shaving to optimisation at the grid connection point. For heat recovery, we plan sizing, temperature levels and transfer points for heating, hot water, process heat or drying and connect the control system to existing systems. Our installation partners carry out the hydraulic work, while coordination and interface definition remain with us. Profitability calculations, comparison of options and payback are also part of it.
Design of tailor-made systems for sites with surplus energy. From the technical site evaluation and the cooling concept with air, water or immersion to noise and fire protection as well as room and container concepts.

Electrical planning, control cabinet construction, programming and software come from one team. This saves interfaces, coordination effort and time.
Whether control cabinet, software or heating concept: our solutions are already in daily operation at numerous sites. For you, this means technology that has proven itself in practice and pays off.
Existing inverters, storage systems, controls and control systems can be kept and integrated into the new solution. Common protocols and interfaces can be connected directly.
Your path to the project
Every engineering project is different, but the process stays clearly structured. So you know what to expect from the start.
Together, we discuss the goal, site, existing infrastructure and general conditions and define the project scope.
On this basis, we create a technical concept with a comparison of options, a profitability calculation and a quote.
Circuit diagrams, software and control cabinets are created in-house and tested and inspected before delivery.
After installation, commissioning and handover with a test report, we remain your point of contact, whether for maintenance, extensions or new requirements.
HASHLYNK engineering solutions are used wherever energy, control and heat are meant to work together intelligently. This includes operators and planners of PV, hydro, wind or biogas plants and of mining facilities, as well as commercial and industrial companies that want to optimise self-consumption or integrate waste heat into their processes. Farms, energy communities and project developers also benefit from individually designed technology that fits their site exactly.
