B2B Solar Panels, Inverters & Batteries Supplier EU

Empowering Europe’s Solar Professionals with Scalable, Wholesale Solutions

Wholesale Solar Panels, Inverters, Batteries & PV Kits – Built for EU Installers

At 3Buy Solar, we deliver more than components—we deliver supply chain certainty, technical trust, and professional support for Europe’s solar installer community. Our mission is to equip certified solar professionals across the European Union with Tier 1 photovoltaic equipment, tools, and technical know-how to scale faster and serve more customers with confidence. Explore our core categories for professional buyers: solar panels, hybrid inverters, solar battery & energy storage, and complete PV kits ready for job-site delivery.

We’re not a retailer. We’re a strategic B2B solar distributor serving the unique needs of solar installers (check solar installers on ENF), EPC contractors, technical resellers, and clean energy project developers.

Solar Panels for Installers – Sourced for EU Performance

Our photovoltaic modules are sourced from Tier 1 manufacturers with verified bankability. We carry:

• Monocrystalline Modules – including half-cut, PERC, and high-wattage bifacial options
• All-Black and Low-Glare Variants – for architecturally sensitive sites
• Weatherized Modules – salt-mist resistance, PID protection, and snow-load testing for alpine and coastal markets
• Factory-Prewired Kits – with mounting rails, MC4 connectors, junction boxes, clamps, and grounding accessories

We offer expert support for system design, including:

• Site-specific panel selection guidance (light diffusion, tilt angle, roof material)
• Module compatibility matching for inverter and battery systems
• Delivery coordination to job sites with unloading support options

We also provide custom packaging for developers and solar resale partners needing white-label PV panel kits aligned with tender specifications.

Inverters for Every Installation Type

Inverter selection is critical—and we offer a comprehensive catalogue of advanced inverter technologies, including:

• String Inverters (1–110 kW) – 1-phase & 3-phase, with MPPT optimization
• Hybrid Inverters – battery-ready with AC & DC coupling for solar + storage flexibility
• Microinverters – for shaded arrays or complex rooftop segmentation
• Central Inverters – for solar fields, commercial rooftops, and megawatt-scale setups
• VPP-Ready Systems – for grid-balancing, demand-response, and flexible export markets

Our partners include global leaders: SMA, Fronius, Growatt, Huawei, Solplanet, Solax, Deye, AIKO, Solis, KBE Berlin, IBC Flexisun, Electrolux and others.

Key features:

• Smart-grid ready with dynamic curtailment
• Built-in export control & zero-feed-in support
• EN50549 and G98/G99 compliance for EU/UK grids
• Monitoring integrations via Modbus, RS485, and Wi-Fi

Looking for solar inverters with B2B discounts and fast logistics? Our hubs in Hungary, Germany, and Benelux support 2–5 day delivery timelines to major EU markets.

Energy Storage Solutions for EU Installers

Battery-based storage is rapidly becoming standard in European installations. We stock certified energy storage solutions designed to:

• Enhance self-consumption
• Provide emergency backup power
• Enable peak shaving and time-of-use optimization

Product range:

• LiFePO4 Modular Batteries (5 kWh–100 kWh+)
• Wall-mounted, rack-mountable, and stackable packs
• Battery Management Systems (BMS) and monitoring add-ons
• Integrated Hybrid Inverter Kits (battery + inverter + cables)

All storage systems are pre-tested and compatible with:

• Popular inverter brands (SMA, Solis, Huawei, GoodWe, Growatt, Solax, etc.) — check manufacturer pages: SMA, Enphase, Victron, Solis, Huawei, GoodWe, Growatt, Solax
• EV chargers and load controllers
• Grid services like net metering and demand response

For off-grid and backup systems, we support:

• Diesel hybridization (AC coupling)
• Generator priority override controllers
• Solar + battery shelters and containers for remote zones

Installer quick paths to energy storage: choose the flow that fits your project — commercial & industrial (C&I) deployments, containerized BESS, or capacity-based battery packs for hybrid sites.

• Commercial energy storage (C&I ESS) — modular systems for factories, logistics, and campuses.
• C&I BESS 30–500 kWh — pricing & availability — pre-engineered packs for medium C&I loads.
• Containerized BESS solutions — turnkey containers for MW-scale tenders and grid support.
• ESS kits with inverter (turnkey) — matched inverter + battery bundles for fast commissioning.
• Battery modules & packs (OEM/rack) — stackable modules for service or custom builds.
• Battery monitoring & BMS add-ons — metering, protection, and telemetry.
• Battery mounting & racking — certified frames and enclosures.
• Off-grid generators & hybrid backup — diesel/solar hybrid for remote or critical sites.

• 2–5 kWh compact batteries — small systems and microgrids.
• 5–8 kWh battery packs — light commercial and agri sites.
• 9–10 kWh systems — hybrid homes and SOHO offices.
• 12–14 kWh modules — scalable wall/rack systems.
• 15–20 kWh high-capacity — SME and small C&I loads.
• 20–30 kWh units — medium C&I rooftops and microgrids.
• All solar battery storage — view the full range.
