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.
Core procurement parameters

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.
