FIXED STORAGE / LOAD–DURATION / UBP

Stationary battery storage for defined loads and duration

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 brief
01Critical loads
Name the circuits or equipment that must remain available.
02Power and energy
Separate instantaneous demand from operating duration.
03System interfaces
Confirm inverter, BMS, protection, communications and expansion assumptions.
04Responsible handoff
Assign design, installation, commissioning and warranty routes.
01 / Build the requirement from the load, not a battery headline

Build the requirement from the load, not a battery headline

01

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?
02

Power profile

Capture continuous demand, starting peaks, phase arrangement and simultaneous operation.

What is the measured or documented peak, and which starts can overlap?
03

Duration and usable energy

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?
04

Integration model

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?
02 / Keep the system open until four gates are confirmed

Keep the system open until four gates are confirmed

01

Load profile

Confirm
Measured or documented continuous demand, starting peaks, sequence and required duration.
If unresolved
Nominal kWh cannot establish runtime or starting capability.
02

Electrical architecture

Confirm
Voltage, phases, inverter topology, grid/generator/PV relationship, protection and operating modes.
If unresolved
A battery and inverter can have compatible headline ratings but incompatible interfaces.
03

Installation environment

Confirm
Indoor/outdoor location, temperature, ventilation, enclosure, access, mounting and fire-safety context.
If unresolved
A generic enclosure rating does not approve a real installation.
04

Project responsibility

Confirm
Named designer, installer, commissioning party, warranty owner and service route.
If unresolved
Equipment supply alone does not make a commissioned storage system.
03 / Confirm

04 / Prepare the request

Prepare the request

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.

  1. 01

    Operating objective

    State outage backup, load shifting, PV self-consumption or another defined objective.

  2. 02

    Critical loads

    List equipment, rated demand, starts and which loads operate together.

  3. 03

    Power profile

    Provide continuous and starting power, phases, voltage and measurements if available.

  4. 04

    Duration

    State the required operating time and reserve assumptions for the defined load.

  5. 05

    Electrical context

    Describe grid, generator, PV, inverter and existing protection or switchgear.

  6. 06

    Installation context

    Add location, temperature, space, ventilation, access and enclosure requirements.

  7. 07

    Integration responsibility

    Name who designs, installs, commissions and approves the combined system.

  8. 08

    Scale and delivery

    Give sites, quantities, destination, timing and required documents/service.

05 / Buyer questions

Buyer questions

Can I choose stationary storage by kWh alone?

No. Usable energy, continuous and starting power, operating limits, actual loads, duration and system interfaces all affect the configuration.

Can UBP guarantee runtime from a device list?

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.

Is a large portable station a substitute for fixed storage?

Not automatically. Fixed systems have different integration, protection, installation, service and responsibility boundaries.

Can additional battery modules be added later?

Only if the exact platform, BMS, inverter, firmware, cabling and approved expansion rules support the proposed configuration.

Does equipment supply include design and installation?

Only when expressly scoped. UBP can coordinate sourcing and trade; qualified parties must own engineering, installation, commissioning and final suitability.

06 / Research and technical sources

Research and technical sources

Market references inform terminology and buyer questions. Technical statements rely on the listed primary sources.
