Contact 3Buy Solar – Solar PV, BESS & Energy Systems

Need a price, stock confirmation, technical answer or help with an existing order? Get in touch with the team that deals with it.

3Buy Solar works primarily with professional solar installers, EPCs, resellers, contractors and approved trade buyers across Europe. Our teams handle solar PV wholesale, BESS distribution, solar inverter and battery sourcing, complete solar PV kits, off-grid equipment and wider energy system requirements.

The official 3Buy Solar B2B Shop is available at Buy-Solar.Online. You can use the shop when the requirement is straightforward and contact us directly when it is not.

A quotation, a compatibility question, a pallet requirement and a commercial BESS project are four very different conversations. We would rather get you to the right person than make you work through a generic support queue.

Solar Panel, Inverter & Battery Storage Prices

Looking for a current solar panel price, solar inverter price or battery storage quotation?

Send us:

• the exact product or specification
• required quantity
• delivery country
• required delivery date
• project type, where relevant

That gives us something useful to work with.

Solar panel wholesale prices

Solar panel pricing may depend on module quantity, pallet size, stock position, delivery destination and current manufacturer pricing.

For professional purchasing, compare more than the price per panel. €/Wp, pallet quantity, module dimensions, warranty, freight and availability can change the real project cost considerably.

Solar inverter wholesale prices

For solar inverters, include the required power, phase configuration and whether the project is on-grid, hybrid, battery-ready or off-grid.

The cheapest inverter is not much of a bargain if the MPPT configuration, battery voltage, backup capability or grid certification does not fit the project.

Solar battery and BESS prices

Battery storage pricing should always be checked against what is actually included.

A quoted battery price may cover only the battery modules, while a functioning system could also require a BMS, controller, rack, cabinet, cables, hybrid inverter, PCS, EMS or other equipment.

If you need commercial or industrial BESS pricing, send us the required usable capacity, charge/discharge power, application and project location where possible.

A useful quotation starts with a useful specification.

Project Pricing, Pallet Quantities & B2B Quotations

Not every professional requirement belongs in a shopping cart.

Contact 3Buy Solar B2B Sales when you need:

• solar panel pallet or larger-volume pricing
• multiple solar inverters
• solar battery project quantities
• commercial or industrial BESS
• complete solar PV kits
• hybrid or off-grid systems
• project-specific sourcing
• alternative products
• recurring purchasing requirements
• delivery planning for larger projects

Approved professional buyers can request project and volume quotations where standard webshop pricing does not reflect the scale or structure of the requirement.

We are multibrand. If the exact product requested is unavailable—or there is a technically better option—we can look at alternatives instead of forcing a project around one manufacturer.

The project comes first.

Solar Inverter & Battery Compatibility Support

One of the most common questions we receive is:

Will this battery work with this inverter?

Sometimes the answer is obvious. Sometimes it absolutely is not.

Matching the DC voltage is not enough to prove compatibility.

Depending on the manufacturer and system, we may also need to check:

• approved battery compatibility lists
• BMS communication
• CAN or RS485 protocol requirements
• inverter firmware
• battery operating voltage
• maximum charge and discharge current
• supported battery quantity
• parallel configurations
• meter requirements
• EPS or backup configuration
• accessories and communication devices

When contacting us, send the exact inverter model and exact battery model. If several batteries, BMS units or parallel branches are planned, include that as well.

Our technical team works from manufacturer documentation, manuals, datasheets and compatibility information rather than guessing whether two products “should probably work.”

Order Processing, Delivery & Logistics

Already ordered from the 3Buy Solar B2B Shop?

For questions about an existing order, include your order number or quotation reference whenever possible.

Our order processing, logistics and customer service teams can help with:

• order status
• stock allocation
• dispatch
• freight
• delivery information
• commercial documentation
• product documentation
• returns
• warranty-related administration
• missing or damaged shipments

Solar logistics is not the same as shipping a box of office supplies.

Solar panels normally move by pallet or larger freight quantities. Battery energy storage equipment can be heavy and may require regulated transport. Commercial BESS can require project-specific logistics and delivery planning.

That is why we operate through European warehouses, hubs and regional logistics arrangements rather than treating every shipment the same way.

European Warehouses, Hubs & Pickup Support

3Buy Solar operates across multiple European markets with warehouse, hub and pickup arrangements supporting professional solar PV and energy storage distribution.

Our physical logistics network helps us handle everything from individual solar inverters and electrical components to palletised solar panels and larger battery energy storage requirements.

Before travelling to a warehouse or pickup point, confirm availability and collection arrangements with the relevant team.

A product appearing in the wider European network does not automatically mean it is available for immediate collection at every location.

For larger project deliveries, contact us before ordering if the installation date, unloading requirements or delivery access are critical.

Professional 3Buy Solar B2B Accounts

The 3Buy Solar B2B Shop is built primarily around professional purchasing.

Typical customers include:

• solar installers
• electricians
• EPC contractors
• resellers
• solar and energy companies
• developers
• approved trade buyers

Professional accounts are screened and approved through the registration process.

If you are registering for a professional account, use accurate company information. If there is a problem with an existing account, contact us using the same email address used during registration whenever possible.

The online shop handles the straightforward part of purchasing.

When a project needs project pricing, technical input, a special quantity or something not listed online, there are real people behind it.

Can’t Find the Solar Product You Need?

Ask us.

A professional solar distributor’s available sourcing options are not always identical to what happens to be visible in the webshop at a particular moment.

If you cannot find a specific:

• solar panel
• solar inverter
• solar battery
• hybrid inverter
• BESS component
• EV charger
• mounting product
• electrical component
• off-grid product
• complete solar PV system

send the manufacturer, model and quantity required.

If the requested product is unavailable, we may be able to suggest an alternative based on technical requirements, compatibility, availability and price.

That is one of the reasons we stay multibrand.

Comparing European Solar Wholesalers? Send Us the Requirement

Professional installers looking for a European solar wholesaler, solar distributor or BESS supplier have plenty of established options.

3Buy Solar operates in the same European professional sourcing market as companies such as Memodo, Krannich Solar, Segen, BayWa r.e. Solar Trade, Energy3000, Menlo Electric, SolarKit and KENO.

If you are comparing suppliers, compare the actual requirement rather than only the logo at the top of the website.

For solar PV and battery storage procurement, look at:

• actual product price
• solar panel €/Wp
• inverter specification
• battery storage €/kWh
• what the BESS quotation actually includes
• real stock position
• pallet quantity
• freight
• lead time
• compatibility
• technical documentation
• warranty route
• after-sales support

Sometimes the lowest unit price wins.

Sometimes an installer needs the correct product, in the correct configuration, in the correct place, on Tuesday.

Those are not always the same offer.

We do not claim to be the right supplier for every company or every project.

Give us the requirement and compare for yourself.

Contact 3Buy Solar B2B Sales Before a Large Project

For larger solar PV, energy storage or EPC requirements, contacting us early usually makes the process easier.

Useful information includes:

• project location
• solar PV capacity
• required inverter power
• required battery capacity
• grid connection
• backup requirements
• expected installation date
• preferred manufacturers
• required quantity
• delivery conditions

For commercial battery storage, it also helps to tell us what the system is expected to do.

That may include:

• self-consumption
• peak shaving
• load shifting
• backup
• off-grid operation
• generator integration
• energy management
• other project-specific applications

The more we understand the project, the less likely we are to waste your time quoting equipment that does not fit it.
