Current document status
Request the exact member datasheet, nameplate, BMS/communication schedule, current limits, wiring, supplied BOM, transport evidence and warranty before release.
Current source evidence
Keep energy, voltage and current on the same member
Battery selection requires the exact electrical member and the connected inverter/system design.
Member route
50–300 Ah members; 640–3,840 Wh table routes
Energy and runtime
Nominal Wh does not establish usable energy or runtime; confirm discharge rate, cutoff, reserve, temperature and conversion losses.
BMS and compatibility
Voltage and LiFePO4 chemistry do not prove inverter/BMS communication, firmware, current limits or warranty compatibility.
System/BOM scope
For all-in-one routes, confirm whether battery, inverter, PV input, cables, protection, enclosure, commissioning and installation items are included.
Storage RFQ checks
Six checks before finalizing the battery or ESS
Define the selected member, electrical interfaces, operating duty and delivered scope.
Exact model
Request full model/suffix, revision, nameplate and table row.
Energy and power
Confirm nominal/usable energy, continuous/peak power/current, discharge limits, cutoff, reserve and temperature.
BMS and inverter
Confirm CAN/RS485 or other protocol, firmware, approved inverter list, settings and fault behavior.
PV and AC scope
For ESS, confirm PV/MPPT, AC input/output, grid/backup mode, loads, protection and transfer path.
Mechanical and safety
Confirm rack/case, terminals, cable, grounding, ventilation, transport, fire/site requirements and installation responsibilities.
Evidence and supply
Request manual, wiring, certificates for exact model/destination, BOM, warranty, packing, lead time and substitution controls.
Storage boundaries
A battery or all-in-one headline is not a complete project guarantee
Final capacity, compatibility, backup and grid behavior require the exact member and project-specific design.
Family-member boundary
Do not transfer energy, voltage, current, cycle, BMS or mechanical data across members.
Usable energy boundary
Nominal capacity differs from usable energy due to DoD, current, temperature, cutoff, losses and reserve.
Compatibility boundary
BMS pairing, firmware and inverter approvals require written exact-model evidence.
ESS scope boundary
All-in-one wording does not establish delivered PV, AC, battery, cables, protection, installation or grid-approval scope.

Storage FAQ
Questions to close before quotation
Exact member documents and project interfaces determine the final answer.
Which member applies to this LP 12.8 V LiFePO4 storage battery?
The current table route is 50–300 Ah members; 640–3,840 Wh table routes. Request the exact selected code, nameplate and latest table before quotation.
Can nominal Wh be used as backup runtime?
No. Runtime requires usable DoD, load, power limits, conversion losses, cutoff, reserve, temperature and battery condition.
Will it work with any same-voltage inverter?
No. Confirm BMS protocol, firmware, current/power limits, settings and the exact-model compatibility approval.
What should the RFQ include?
Request exact datasheet/manual, BMS interface, wiring, current limits, certificates/transport files, BOM, warranty and delivery scope.
