BEFORE HARDWARE REACHES SITE
Four details that can change how smoothly a storage project moves.
Small mismatches create large delays. Before an equipment list is finalized, Linker looks at the electrical requirements, product compatibility, documentation and support needs around the system.
1
01 · ELECTRICAL FIT
Match the hardware to the real operating requirement.
System power, usable battery capacity, voltage range, charge and discharge limits, backup requirements and operating conditions all affect product selection. We review the available technical data to help narrow the configuration before the order is confirmed.
📄
Project output: A clearer equipment shortlist and the key electrical parameters behind it.
2
02 · COMMUNICATION
Make sure the inverter and battery can actually talk.
Battery storage depends on more than matching voltage. CAN or RS485 communication, supported product combinations, wiring assignments and required settings can determine whether the equipment works together as intended.
🔌
Project output: Relevant compatibility, wiring and communication information for the selected combination.

03 · GRID DOCUMENTATION
The paperwork should not become the missing component.
Depending on the equipment and project, installers may need unit certificates, declarations, protection information or other grid-related documents. We keep the documentation on file connected to the hardware being supplied.

Technical support should continue after the order.
Questions do not always stop once the hardware arrives. For equipment purchased through Linker, our German team remains available for product questions, documentation, fault information and warranty coordination.

HARDWARE PORTFOLIO
From the home battery room to larger energy projects.
The scale changes. The need for the right hardware does not. Linker works across residential storage, commercial battery systems and larger containerized BESS applications.
01 · RESIDENTIAL STORAGE SYSTEMS
Hybrid inverters and modular batteries built around the home.
Residential storage usually starts with a simple question: how much power and usable energy does the property actually need? Linker supplies three-phase hybrid inverter and high-voltage battery options across several established product families, with matching meters and accessories where required.

02 · COMMERCIAL & INDUSTRIAL
More energy. More variables. More reason to get the combination right.
Commercial storage may involve larger inverter power, outdoor battery cabinets, energy-management requirements or several pieces of equipment working together. Linker supplies C&I storage products for applications including self-consumption, peak-demand management and larger on-site energy systems.

BEFORE YOU COMMIT TO THE HARDWARE
The questions worth asking before the order becomes a site problem.
Compatibility, documentation and project requirements can change from one system to another. These are some of the questions customers raise with us before finalizing equipment.
How does Linker check whether an inverter and battery combination is suitable?
We review the exact inverter and battery models against the technical information available for that combination, including the compatibility documentation on file and communication requirements where relevant.
Compatibility should always be checked at model level rather than assumed from the brand name alone.
Compatibility should always be checked at model level rather than assumed from the brand name alone.
Can Linker help with battery sizing before we order?
Yes. Where sufficient project information is available, we can review requirements such as load profile, power demand, desired storage capacity and the intended application to help narrow the equipment options.
The final system design and installation remain the responsibility of the qualified professionals responsible for the project.

What happens when firmware affects inverter-battery communication?
Firmware can affect communication behavior and supported settings. Where relevant information is available, we work from the documentation on file and technical guidance for the equipment being supplied.
For an existing installation, the exact inverter model, battery model and firmware versions help us understand the issue more quickly.

Can Linker supply combinations that are not shown on a compatibility list on file?
If a proposed combination is not supported by the information on file, we do not present it as a confirmed compatible pairing.
Send us the exact models you are considering and we can check the documentation available for that combination.

What technical documents can Linker provide?
Documentation varies by brand and product. Depending on the equipment, available files may include datasheets, manuals, compatibility information, declarations of conformity and the relevant unit certificates.
If a specific document is required for your project, tell us before ordering so we can check its availability for the exact product.

Does Linker carry out installation and final commissioning?
Linker supports the equipment side of the project, including product selection, technical information, documentation and after-sales coordination.
Electrical installation, site commissioning and final grid-connection responsibility remain with the qualified contractor responsible for the installation.
