I'm Tom Smith, Senior Product Manager at Techfine. I write about solar inverters, lithium battery storage, MPPT charge controllers, and OEM/ODM sourcing for B2B buyers. My work focuses on helping solar distributors, importers, and private-label brands match product specifications with real market needs. This includes inverter selection, battery compatibility, branding requirements, MOQ planning, and factory-side project communication. At Techfine, I look at products from both sides: what buyers need to sell, and what a manufacturer can reliably build. My articles are written to help procurement teams ask better questions, compare products more clearly, and avoid common sourcing mistakes before placing an order.
