The Linker Standard

Engineering standards matched to European grid reality.

How our technical support and authorised multi-brand supply de-risk your commercial and residential installations.

DIMENSION	Common Field Friction	The Linker Delivery Standard
🔌 Protocol & Pinouts	Communication faults and startup delays caused by unverified firmware pairings or mismatched CAN/RS485 pinouts on site.	✓ Documented Pinouts: RJ45 wiring diagrams and DIP switch tables provided for first-visit commissioning. TESTED
📑 Grid Sign-off	Grid registration stalled by missing unit certificates or uncertified multi-brand hardware combinations.	✓ Unit Certificates: VDE-AR-N 4105 & 4110 unit certificates on file for utility submission. VDE CERT
📦 Order Fulfillment	Split shipments arriving days apart, causing installation site downtime, missing balance-of-plant components, or uncoordinated deliveries.	✓ Consolidated Orders: Hybrid inverters, modular battery stacks, and matching smart meters delivered together as one consolidated order. COMPLETE
🛡️ Warranty & Support	Unclear warranty routes, overseas communication delays, and lack of technical assistance after delivery.	✓ German Technical Desk: Direct technical diagnostics and warranty claim coordination under German commercial law. SUPPORT

Operational Backbone

Three pillars powering our project delivery.

Combining German-based supply, certified multi-brand engineering, and a streamlined B2B trade portal.

Consolidated order dispatch from Germany

01 · GERMAN SUPPLY

01 / 03

Authorised Supply from Germany

Operating out of Barleben (Saxony-Anhalt), we supply high-voltage batteries, three-phase hybrids, and smart meters as authorised distributor for GoodWe, SAJ, Pylontech, EcoFlow and CRRC. Orders ship from Germany to installation regions across Europe, with lead times confirmed at order.

Availability and lead time confirmed with every order
Complete package fulfillment with all balance-of-plant accessories
EU reverse-charge invoicing for registered trade partners

Inverter battery compatibility and protocol matching

Inverter-Battery Protocol Integration

We eliminate on-site commissioning friction before hardware arrives at the jobsite. Every inverter-battery pairing is validated against factory firmware matrices, DC operating voltage windows, and communication registers.

Verified RJ45 pinout assignments and DIP switch address maps
Factory-certified firmware compatibility across GoodWe, SAJ, and Pylontech
Zero guesswork or speculative on-site wiring

03 · PARTNER OPERATIONS

Hardware Portfolio

Hardware selected for technical reliability.

We focus strictly on Tier-1 brands with verified compatibility, proven efficiency, and comprehensive European grid certifications.

01 · RESIDENTIAL STORAGE KITS

3-Phase Hybrid Inverters & High-Voltage LFP Towers

Three-phase hybrid inverters paired with stackable high-voltage LFP towers (5–20 kW / 5–30 kWh). Low 160V startup voltage ensures early morning solar harvesting, while 100% asymmetric output handles heavy single-phase loads without tripping.

Power / Capacity: 5–20 kW / 5–30 kWh
Backup Transfer: < 10 ms UPS Standard

Field Experience

Trusted by European installers and EPC contractors.

From standard residential installations to high-capacity commercial BESS projects.

C&I PEAK SHAVING

Marcus Weber

Head of Technical Planning, Solar EPC · Munich

“Linker's load modeling showed we could shave commercial peak demand without an expensive transformer upgrade. The VDE 4110 compliance pack was approved on the first submission.”

COMMERCIAL BESS

Stefan Hartmann

Managing Director, NordSolar Grid · Hamburg

“Having Linker's engineering desk verify equipment sizing and confirm protocol compatibility gave our project team complete confidence. Delivery to the pad went smoothly without installation site delays.”

TRADE DILIGENCE & GOVERNANCE FAQ

Frequently asked questions regarding governance, warranty, and supply.

Direct engineering and corporate answers regarding our supply authorizations, German legal liability, and how orders are supplied.

What is Linker’s authorized relationship with hardware manufacturers, and how is factory warranty validity protected?

Linker operates as an authorized supply and integration partner for Tier-1 manufacturers, including GoodWe, SAJ, Pylontech, and CRRC. We only supply hardware configurations that comply strictly with the certified pairing lists on file. Every project shipment includes traceable equipment serial numbers and warranty registrations, ensuring 100% factory warranty validity under German and European law.

How is legal accountability and warranty liability structured under German commercial law?

All supply agreements are executed directly with Linker Technology GmbH (registered in Germany under HRB 33824) and are governed by the German Commercial Code (HGB) and Civil Code (BGB). Linker acts as your direct contractual warranty partner in Europe. You do not negotiate with overseas factories; Linker coordinates all technical diagnostics, warranty claims, and replacement hardware dispatch directly from Germany.

What does Linker operate from Barleben, and what happens before an order ships?

Linker Technology GmbH operates from Barleben (Steinfeldstraße 3, 39179 Barleben, Germany). Three things happen there before an order ships:

Authorised Supply: Residential three-phase hybrid packages, commercial storage cabinets, battery modules and high-voltage control units (BPU), supplied as authorised distributor with availability confirmed per order.
Incoming Quality Inspection: Verification of package contents, firmware versions, and enclosure integrity before dispatch.
Engineering Review Desk: Dedicated technical support for communication pinout verification and VDE compliance pack assembly.

Who issues the grid compliance certificates, and how is acceptance guaranteed by German grid operators (VNB)?

All compliance documentation consists of authentic, accredited test reports (Einheitenzertifikate and Komponenten-Zertifikate) issued by internationally recognized testing bodies (such as TÜV Rheinland, TÜV SÜD, or DNV) in accordance with VDE-AR-N 4105 (Low Voltage) and VDE-AR-N 4110 (Medium Voltage). Linker bundles the unit certificates and verified protection parameters directly with your project documentation.

How are commercial orders and fulfillment milestones processed for European partners?

Standard residential and light commercial packages are confirmed with availability and a dispatch date at order, then shipped from Germany as one consolidated delivery. For multi-megawatt container BESS and custom commercial projects, technical parameters are locked in writing with a binding bill of materials (BOM), production timeline, and scheduled European transport.
