CALLSUN is a PV module brand and manufacturer with in-house product development, manufacturing and testing capabilities. We support distributors, installers, system providers, equipment manufacturers and project buyers with standard modules, custom module development and product selection.

Our current portfolio includes standard and custom PV modules, hybrid solar inverters and LiFePO4 battery storage. We also provide reference solar-plus-storage configurations combining selected components. Visit the product and solution pages for the currently listed options.

Start by comparing our existing models with your dimensional and electrical requirements. If a listed model does not fit, CALLSUN can assess a custom module request based on the available space, target output, structure and connection requirements. Sample trials and production validation can be discussed following the requirements review.

Please provide the product model or target specifications, estimated quantity, destination country or port and required delivery schedule. Include any application, customization or documentation requirements. For a system inquiry, also share the intended loads and local electrical supply requirements.

These depend on the product, configuration, quantity and supply arrangements. Samples or trial orders can be discussed for the selected product. Custom module requests may require additional assessment and sample validation. CALLSUN will confirm the applicable order conditions and schedule with your quotation.

Available documents are listed in our Downloads section and on relevant product pages. Certification coverage must be checked for the exact model, configuration and target market. If the required document is not listed, contact CALLSUN with the product and documentation needed.

CALLSUN lists reference configurations combining PV modules, an inverter and battery storage. The equipment and accessories included in an order are confirmed in the quotation and bill of materials. Final selection depends on load demand, installation conditions and local requirements. System manuals are being prepared; contact us for currently available product information.

CALLSUN can review product specifications and application requirements to help identify suitable options. For system inquiries, share the proposed equipment, electrical requirements and intended loads. Final electrical design, structural assessment, installation and grid connection must be confirmed by qualified local professionals.
