中国是全球储能制造重心，但供应商水平参差。下面是一份面向出海经销商与 EPC 的尽职调查清单，帮你避开最常见的坑。China is the manufacturing center of global storage, but supplier quality varies widely. Here is a due-diligence checklist for export distributors and EPCs to avoid the most common pitfalls.
1. 认证是否对齐你的目标市场1. Certifications Aligned to Your Market
先确认供应商能给你目的国要的文件：欧盟看 CE（IEC 62619）+ UN38.3；美国并网/投标看 UL 1973/9540A。绿岭 Lulin 全系提供 CE / IEC 62619 / UN38.3 / MSDS / ISO 9001，GBP51.2 机架系列获 UL。First confirm the supplier can give you the documents your market needs: EU wants CE (IEC 62619) + UN38.3; US grid-tied / tender wants UL 1973 / 9540A. Lulin provides CE / IEC 62619 / UN38.3 / MSDS / ISO 9001 across the range, with UL on the GBP51.2 rack series.
2. 逆变器兼容性是否真能对接2. Real Inverter Compatibility
问清楚通信协议（CAN / RS485）与具体兼容机型，而不是只听"兼容主流"。绿岭 Lulin 维护 65+ 逆变器机型的兼容清单，覆盖 Deye、Growatt、Victron、GoodWe、Sol-Ark，下单前按你的型号核对。Ask for the communication protocol (CAN / RS485) and the exact compatible models — not just “compatible with mainstream”. Lulin maintains a 65+ inverter compatibility list covering Deye, Growatt, Victron, GoodWe, Sol-Ark, verified against your model before order.

3. 工厂与制造体系能否经得起审核3. Factory and Manufacturing System That Withstands Audit
靠谱的供应商应能提供制造体系与质控说明，并支持远程或现场审核。绿岭 Lulin 作为专注出海的供应链整合方，与通过国际认证的制造体系深度合作，从分选、PACK、BMS 到出厂全检全链可查。A solid supplier should explain its manufacturing system and QC, and support remote or on-site audit. Lulin, a supply-chain partner focused on exports, works with internationally certified manufacturers — cell sorting, PACK, BMS and end-of-line QC are all traceable.

4. 起订、交期与售后是否透明4. Transparent MOQ, Lead Time and After-Sales
MOQ 与交期应写入报价单而非口头；售后要有海外服务节点与备件机制。绿岭 Lulin 询价 1 个工作日内返回方案与交期窗口，海外多地设售后服务中心。MOQ and lead time should be in the quote, not verbal; after-sales needs overseas nodes and spares. Lulin returns a plan and lead-time window within 1 business day, with overseas service centers.
5. 沟通与定制响应速度5. Communication and Customization Speed

常见问题Frequently Asked Questions
中国储能供应商应提供哪些认证？What certifications should a China ESS supplier provide?
欧盟：CE（含 IEC 62619）加 UN38.3；美国并网/投标：UL 1973 / 9540A 加 UN38.3。绿岭 Lulin 每批提供这些加 MSDS 与 ISO 9001。For the EU: CE with IEC 62619 plus UN38.3. For US grid-tied / tender: UL 1973 / 9540A with UN38.3. Lulin provides these plus MSDS and ISO 9001 per batch.
怎么核实逆变器兼容性？How do I verify inverter compatibility?
问清协议（CAN/RS485）与具体机型清单，让其核对你的逆变器。绿岭 Lulin 维护 65+ 机型清单，下单前核对你的型号。Ask for the protocol (CAN / RS485) and the exact model list, then have them confirm your specific inverter. Lulin maintains a 65+ model list and verifies yours before order.
需要审厂吗？Should I audit the factory?
需要。要求看制造体系说明并安排远程或现场审核。绿岭 Lulin 与通过国际认证的制造体系合作，可展示从分选到出厂全检的质控链。Yes — request a manufacturing-system overview and a remote or on-site audit. Lulin works with internationally certified manufacturers and can show the QC chain from cell sorting to end-of-line test.
低起订量是危险信号吗？Is a low MOQ a red flag?
不一定，按层级灵活起订很正常。危险信号是含糊或只口头承诺的 MOQ 与交期——务必写进报价单。Not necessarily — flexible MOQ by tier is normal. The red flag is a vague or verbal-only MOQ and lead time. Insist on both written in the quote.
