Buyer's guide to procuring bulk LiFePO4 batteries: certifications, BMS checks, MOQ, lead times, and practical RFP templates for industrial & solar buyers. This document has been published with the support of Andy Walker, Otto VanGeet, Tom Harris and Chandra Shah of the National Renewable Energy Laboratory (NREL). The enclosed technical template language is intended to provide only example language for agencies to consider in the process of assembling. The Procurement phase covers purchasing components such as PV modules and inverters, as well as identifying and mitigating risks. It involves supplier selection and onboarding, and conducting inspections, and tests to qualify materials to be used in construction throughout the procurement process. Solar DC combiner boxes link PV inverters and PV arrays, combining the output of a large number of strings to improve PV performance. Includes an added lock + easy-snap latches—all at no extra cost. Cons: Requires space and can be costly. Pros: Intelligent monitoring, energy efficiency.
