Behind-the-meter peak shave
Record the demand interval, the hours of storage requested, and whether the site already has solar.
Industrial battery energy storage system
VoltLink Supply is an independent sourcing partner. The desk collects the application, usable capacity, rated power, quantity and US destination, then requests factory quotations for that brief.
A family name does not state chemistry, duration, DC voltage window or whether the block is AC-coupled or DC-coupled. Those fields stay open until the proposed supplier answers them for the exact model.
Exact-item files to request
A family brochure is not evidence for the quoted industrial battery energy storage system. Ask the proposed supplier to bind each file to the manufacturer name and the model on the quotation.
- Datasheet. Usable capacity in kWh, rated power in kW, and the depth of discharge used for that capacity.
- Drawing. Footprint, clearance, cable entry and the enclosure rating the yard or room must accept.
- Battery management system note. What the BMS reports, and which protocol the site controller is expected to speak.
- Thermal management description. Liquid or air path, and the ambient range the rating assumes.
- Transport and listing questions. Whether a current UN 38.3 test summary and a US safety listing exist for this model, not for a related product.
Approvals that remain open
- Interconnection. Utility review, protection settings and a grid-forming or grid-following mode are project decisions. This desk does not approve them.
- Cycle life basis. A cycle count without temperature, C-rate and end-of-life capacity is not comparable across quotations.
- Round-trip efficiency. Ask for the test cycle, auxiliary loads included, and whether the figure is AC or DC.
- Bidirectional inverter boundary. Record whether power conversion is inside the quoted block or a separate line.
- Warranty exclusions. Throughput limits, ambient derating and who replaces modules belong in the commercial comparison, not in a slogan.
Read the interface review before the brief is sent, and the procurement note for the field list.
Sample figures a buyer can write, still unconfirmed
These are hypothetical example inputs for an industrial battery energy storage system brief. They are not VoltLink Supply ratings, a supplier quotation or a validated design. IP and NEMA enclosure descriptions require separate evidence; neither implies the other. Replace each value with the buyer's requirement and have project clearances and electrical limits checked by qualified reviewers.
| Field to confirm | Example the buyer might enter |
|---|---|
| Usable capacity and depth of discharge | 2,000 kWh usable at 90 percent depth of discharge |
| Rated power and duration | 500 kW for 4 hours, plus a 625 kW 10 minute question |
| Maximum system voltage | 1,000 V to 1,500 V DC class |
| AC interface | 480 V, 3 phase, 60 Hz |
| Round-trip efficiency | 88 percent to 92 percent AC, cycle and auxiliaries named |
| Cycle life | 6,000 cycles at 0.5 C, 25 C, to 80 percent remaining |
| Calendar question | 15 years at 25 C, still a supplier answer |
| Enclosure rating and ambient | IP55 or NEMA 3R, from -20 C to 50 C |
| Site altitude | 2,000 m before derating is described |
| Thermal management | Liquid path, cell target 25 C |
| Charge rate | 0.25 C continuous charge |
| Auxiliary load | 8 kW HVAC and controls, included or excluded |
| Footprint and clearance | 6.1 m by 2.4 m, 1.5 m service clearance |
| Mass | 28 t per container as a lifting question |
| Fault current | 50 kA AC question at the point of connection |
| Power factor | 0.8 lagging to 1.0, stated by the supplier |
| Step response | 200 ms question, not a site acceptance test by this desk |
| Noise question | 75 dBA at 1 m, method still open |
| Battery management system | Cell voltage, 25 C, and alarm points listed |
| Bidirectional inverter | Inside the 500 kW block, or a separate 480 V line |
| Grid-forming mode | Asked as yes, no, or not in this firmware |
| SCADA points | At least 40 points named before controls are compared |
| Open-circuit voltage | PV side question if the DC bus can see 1,500 V cold |
| MPPT window | Asked when a shared converter is in the same quotation |
Where the same equipment family is bought
These are procurement contexts, not completed projects and not a claim that one supplier covers every line.
Process-plant backup
Separate ride-through seconds from a multi-hour shift. The power and energy ratings are different questions.
Fleet-yard charging
State charger power, dwell time and whether storage is asked to cap the service drop.
Solar-plus-storage bus
Name the DC voltage class and whether coupling is AC or DC before inverter quotations are mixed in.
Distributed energy node
List SCADA points the owner already collects so communication is a requirement, not an assumption.
Questions buyers raise before a quotation
Ratings
What must usable capacity and rated power confirm?
Ask for usable kWh at a named depth of discharge, and rated kW at a named ambient and duration. A nameplate kWh without the discharge basis cannot be lined up against another offer.
Why does chemistry stay a question?
Lithium iron phosphate and nickel manganese cobalt packs change cycle life, thermal management and transport paperwork. The desk records the buyer preference and asks the supplier to state the chemistry of the quoted model.
Commercial comparison
How should commercial scope be lined up?
Compare specification, quantity, currency, packaging, freight, taxes, included cables, warranty basis and exclusions together. A lower unit price is one side of the choice. The other side is a delivered scope that shows omitted accessories before award. VoltLink Supply does not publish a savings percentage.
Can a target budget be sent without a live price?
Yes. State currency and whether the figure is per kWh, per system or the whole order. High-end, mid-range, budget or undecided is a preference, not a verified tier.
Documents and responsibility
Who approves the installation?
Code review, structural checks, fire-authority conditions and interconnection stay with qualified parties. The sourcing desk coordinates the equipment request and the files you ask suppliers to attach.
Where do the inquiry names live?
Open the inquiry options and select a name to prefill the quote dialog. That list is not inventory.
Send the opening storage brief
Use the form to request factory quotes. Include the application, usable capacity, rated power, quantity, US destination and the documents you want checked.
- Known ratings stay in the requirements box.
- Unknown interface points stay marked as open.
- Optional budget needs a currency and a per-unit or whole-order basis.
- Supplier preference does not rank a factory.
