Critical-load boundary
Define what must operate during the target event and what may remain off.
Which circuits, machines or services are critical, and can they be sequenced?FIXED STORAGE / LOAD–DURATION / UBP
A fixed battery system is not selected by capacity alone. Define which loads must operate, their starting and continuous power, the required duration, electrical context and who owns system integration.
Discuss this sourcing briefDefine what must operate during the target event and what may remain off.
Which circuits, machines or services are critical, and can they be sequenced?Capture continuous demand, starting peaks, phase arrangement and simultaneous operation.
What is the measured or documented peak, and which starts can overlap?Translate the operating objective into a stated duration and usable-energy basis.
How long must the defined load run, and at what reserve or depth-of-discharge assumption?Clarify existing PV, inverter, grid, generator, monitoring and responsible project parties.
Is this a new complete system, an extension or a battery for an existing platform?| Criterion | Request | Compare |
|---|---|---|
| Exact configuration | Battery modules, inverter/charger, BMS, cabinets, protection, monitoring and accessories. | Included quantities, model revisions, alternatives, expansion limits and exclusions. |
| Power and usable energy | Continuous/peak power, usable-energy basis, operating limits and stated assumptions. | The same load case and reserve assumptions rather than nominal capacity alone. |
| Interfaces and project scope | Electrical, mechanical and communications interfaces plus design, installation and commissioning boundaries. | Who confirms compatibility and who supplies every interface item. |
| Evidence and service | Exact-model datasheets, declarations, test evidence, manuals, warranty owner and return/service process. | Model coverage, issuer, document language, response route and separate costs. |
UBP can coordinate requirements, supplier search, comparison and import/export. Electrical design, fire-safety assessment, installation, commissioning, conformity and final suitability remain with named qualified parties.
State outage backup, load shifting, PV self-consumption or another defined objective.
List equipment, rated demand, starts and which loads operate together.
Provide continuous and starting power, phases, voltage and measurements if available.
State the required operating time and reserve assumptions for the defined load.
Describe grid, generator, PV, inverter and existing protection or switchgear.
Add location, temperature, space, ventilation, access and enclosure requirements.
Name who designs, installs, commissions and approves the combined system.
Give sites, quantities, destination, timing and required documents/service.
No. Usable energy, continuous and starting power, operating limits, actual loads, duration and system interfaces all affect the configuration.
A device list starts the brief, but runtime depends on measured behaviour, conversion losses, reserve settings, temperature and system design. The responsible technical party must confirm it.
Not automatically. Fixed systems have different integration, protection, installation, service and responsibility boundaries.
Only if the exact platform, BMS, inverter, firmware, cabling and approved expansion rules support the proposed configuration.
Only when expressly scoped. UBP can coordinate sourcing and trade; qualified parties must own engineering, installation, commissioning and final suitability.
Market references inform terminology and buyer questions. Technical statements rely on the listed primary sources.
