Direct answer
OmniSol accepts trial and sample orders across all BOS product categories — PV cable, connectors, DC and AC protection, combiner boxes and mounting hardware — to allow buyers to verify quality and specifications before placing a commercial container order.
A trial order covering all the product lines you intend to buy commercially gives you a complete quality check in one shipment — testing only one or two categories in the trial and scaling the rest without testing creates an avoidable risk.

BOM procurement notes
Solar BOS Trial Order Supplier should be treated as part of a procurement BOM, not as an isolated catalogue item. The usual starting points are trial order scope (Available across all BOS categories in one consolidated order), typical trial quantity (1–5 units per protection device, 1–2 combiner boxes, 1 reel cable, 1 bag connectors), documentation (TDS, test certificates and packing list included with trial orders). Typical use cases include Supplier qualification before commercial commitment, New product line testing, Certification verification for new market entry. Solar BOS procurement works best when mounting, PV cable, connectors, protection, combiner boxes, distribution boards and accessories are reviewed as one purchasing package. A consolidated BOM reduces missed accessories and helps align ratings across the DC and AC side.
A practical RFQ should describe the required variant, quantity and packing in the same language the site team will use later. For this page, the common option set includes Single category trial (cable, connectors or protection), Full BOM trial across all categories, Certification document package. The RFQ checklist should cover Product list with ratings for the trial, Required certifications for your market, Destination port and Incoterms, Whether this is a pure sample or will include commercial quantities so the quote can be compared across suppliers without hidden assumptions.
For BOS pages, the useful commercial check is whether every line has a destination standard, packing rule, inspection point and shipment sequence. Mixed-container purchasing needs clear labels and carton grouping so the site team can find each item quickly. Before shipment, the inspection record should include Verify product markings against specification; Check certification documents are authentic; Inspect packaging and carton labeling quality. This gives EPC buyers and distributors a cleaner handover from sourcing to receiving, especially when the order is consolidated with other BOS lines from the central products hub.
FAQ
What should I include in a solar BOS trial order?
Include at least one unit of every product line you plan to buy commercially. For cable, one partial reel is enough to test the specification. For protection devices, 3–5 units per model allows basic electrical testing. For combiner boxes, 1–2 units are enough to verify internal configuration and fit. The goal is to test every product category in the trial so there are no surprises when the commercial order arrives.
How long does a trial order take from China?
For stocked products, a trial order typically ships within 1–2 weeks of order confirmation. Transit time depends on the destination and shipping method — air freight for urgent qualification, sea freight for standard. Total time from order to receipt is typically 3–6 weeks by sea for most markets.
What documentation comes with a trial order?
Trial orders include TDS (technical data sheets) for each product line, copies of relevant test certificates, a detailed packing list and pre-shipment photos. If original test certificates are required, this should be specified at the time of order — some certificates require advance notice to obtain from the certification body.
