Our protected Pro Installer price lists are available only to logged-in customers with an approved Installer Account or Premium Installer Account.

This keeps professional pricing separate from public webshop browsing and helps protect manufacturer-specific commercial conditions.

Who Can Access the 3Buy Solar Pro Installer Price Lists?

B2B price-list downloads are available to approved:

• Installer accounts
• Premium Installer accounts

Other account types can continue browsing the public page but cannot download protected Pro Installer PDFs.

If you do not yet have an eligible professional account, use the My Account / registration area to log in or apply for Pro Installer access.

The protected price-list area is intended for professional solar installers, EPC contractors, electricians and technical purchasing teams who need current procurement-ready pricing for solar panels, solar inverter systems, solar batteries, complete kits and energy storage equipment.

Why Installer Price Lists Are Protected

Professional solar pricing can vary according to:

• manufacturer
• product family
• order quantity
• warehouse location
• current stock position
• freight
• project volume
• commercial agreement
• current purchasing conditions

For this reason, manufacturer-specific B2B pricing is commercially sensitive.

Protected access helps 3Buy Solar:

• maintain trade-only pricing
• protect manufacturer and distributor commercial conditions
• provide current professional purchasing documents
• reduce uncontrolled circulation of outdated price lists
• separate public webshop browsing from Pro Installer procurement
• support project pricing where standard price lists are not sufficient

The underlying price-list PDFs are delivered through protected account-controlled access rather than ordinary public WordPress Media Library links.

Solar Inverter Price Lists

Professional solar inverter purchasing should consider much more than €/kW.

When comparing solar inverters, installers should check:

• rated AC output
• single-phase or three-phase architecture
• hybrid, grid-tied or off-grid topology
• low-voltage or high-voltage battery interface
• number of MPPT trackers
• PV operating-voltage range
• maximum PV input current
• battery charge and discharge power
• EPS or backup functionality
• grid-code compatibility
• supported solar batteries
• BMS communication
• monitoring platform
• warranty
• required accessories

Browse the 3Buy Solar Installer Shop for current solar inverter, PV and electrical products available for professional sourcing. buy-solar.online

For hybrid projects, installers should verify battery voltage, BMS communication, firmware compatibility and permitted operating configuration before ordering.

For brand-specific technical guidance, see the SolaX Hybrid Inverter and Battery Compatibility Guide and the Solis Inverter and Battery Compatibility Guide. Both guides emphasise that compatibility depends on the exact inverter family, battery model, voltage architecture, BMS protocol and firmware—not simply the brand name or nominal battery voltage. buy-solar.online
