5kW/10kWh Residential Solar Storage System

What to send with your RFQ

For a faster quotation, send the destination country, target application, expected quantity, preferred connector or battery configuration, local certification needs, branding requirements, installation environment and delivery timeline. If the site is still at concept stage, a short description is enough: vehicle type, parking or storage hours, transformer capacity, solar input if any, and the commercial goal of the project.

For sample orders, the buyer normally verifies installation fit, communication stability, enclosure quality, display language, packing protection and basic user operation. For batch orders, the review should go deeper: firmware version control, serial-number tracking, spare-parts list, packaging marks, carton drop protection, inspection photos and responsibility for after-sales communication.

For distributor or OEM programs, the first decision is usually not the final price. It is whether the supplier can keep the same configuration across repeat orders, provide stable documentation for customs or tenders, and respond quickly when an installer needs wiring or software support. That is why the quote request should include both commercial volume and technical constraints.

SUNFULL NEW ENERGY positions these pages as sourcing references, not only advertising pages. The goal is to help B2B buyers prepare a cleaner RFQ, compare products on real project conditions, and avoid surprises around certificates, grid compatibility, communication protocol, packaging and delivery terms. When a detail is uncertain, our sales engineer can recommend a conservative starting configuration for pilot testing.
