Inside the desk
Normalize the brief, search for original manufacturers willing to quote that brief, and place answers in the same columns so a buyer can read them.
VoltLink Supply specification review desk
VoltLink Supply is an independent sourcing partner for buyers who need factory quotations on storage equipment. The desk records what is known, what is still a question, and which files the proposed supplier should attach to the exact model.
What the desk will ask for
The work starts from the buyer brief, not from a borrowed factory history. VoltLink Supply does not claim authorized distributor status and does not own a factory.
- Identity of the request. Application, usable capacity, rated power, quantity and US destination.
- Identity of the offer. Manufacturer and model on the quotation, matched to the datasheet filename.
- Open engineering items. Interconnection, fire review, structure and controls stay listed as unresolved.
- Commercial identity. Currency, scope, freight and exclusions, compared on the cost page.
Boundaries written in plain language
Outside the desk
Stamping drawings, listing products, witnessing factory tests, promising inventory, or telling a utility the design is acceptable.
Evidence rule
A certificate for a different model, or a brochure for a product family, is filed as background. It is not treated as proof for the line being bought.
Preference rule
High-end, mid-range, budget or undecided describes the buyer. It is not a score VoltLink Supply has audited.
How a brief moves
Specification
Write kW, kWh, voltage and the depth of discharge the energy number uses.
Quantity
Count blocks or racks, and say whether the figure is firm.
Delivered scope
Name the US destination and which accessories must be inside the price.
Supplier documents
List the drawings, test summaries and warranty text you want returned.
Readers who want the electrical questions next should open the compatibility guide. Readers who want named inquiry options should open the catalog. The longer public checklist is the procurement brief.
Two comparisons stay on the review log. An AC-coupled arrangement can leave an existing PV inverter in service and put the storage on its own AC circuit. A DC-coupled arrangement can share one DC bus on a new build when both voltage windows are written down. A container price and a delivered scope are also different readings: freight, cables and documents have to occupy the same columns before either reading is used.
A review log with numbers still marked open
This is a hypothetical request, not a completed review or a supplier offer. Each number is an example input to replace with the buyer's requirement; site clearances, loading and approval limits require qualified review. IP and NEMA enclosure descriptions require separate confirmation and are not interchangeable.
| Desk check | Figure written as a question |

| Maximum system voltage | 1,500 V DC class on the battery bus |
| Round-trip efficiency | 86 percent DC figure, auxiliaries excluded until stated |
| Cycle life | 4,000 cycles at 0.25 C and 35 C to 70 percent remaining |
| Thermal management | Air path, room held from 15 C to 30 C |
| Enclosure rating | IP54 indoor, not the yard rating |
| Battery management system | One CAN map and 12 alarm bits to be named |
| Bidirectional inverter | Separate 250 kW line, 690 V |
| Grid-forming inverter | Not requested on this brief |
| SCADA | 16 existing points the owner already polls |
| Quantity | 2 identical blocks, spares listed as 4 modules |
| Auxiliary | 5 kW room cooling, outside the equipment price |

| Response | 1 second ramp, not a protection setting |
| Noise | 65 dBA at 3 m inside the room |
| Calendar | 10 years at 30 C as a warranty question |
| Open-circuit voltage | Left blank because this brief has no PV bus |
| DC-to-AC ratio | Not applicable until a PV quantity is added |
| Delivery window | 16 to 22 weeks requested, not accepted |
| Budget basis | USD 640,000 whole order, currency stated, not a market price |
Start a brief with the desk
Request factory quotes when the known ratings and the open questions are both in the message. Missing data is acceptable. Invented ratings are not useful to a supplier.
