Power and phase type
Record rated AC output power, peak or overload capacity, single-phase, split-phase, or three-phase output, and the project destination voltage and frequency requirements.
Battery system
Check battery voltage, battery chemistry, BMS communication, supported protocols, and any production-side compatibility notes.
PV input and MPPT
Compare maximum PV input power, PV input voltage range, MPPT quantity, MPPT current, and string design limits.
Grid and backup behavior
Confirm grid mode, off-grid mode, backup output, transfer behavior, generator support, parallel support, and whether the quoted model matches the intended application.
Documents and certificates
Request datasheet, manual, wiring diagram, real product photos, nameplate photos, certificate files by exact model, warranty policy, packing data, MOQ, sample terms, and lead time as supplier-replied items.
Prepare a quote-ready request
Send your product category, project destination, estimated quantity, application scenario, and document requirements. JSMART can help organize production-side materials before quotation.
