Great Power utility battery-system evidence review
Great Power Magna-UTL Outdoor DC Battery Systems
The current Great Power catalogue identifies the DC Outdoor Battery System route for two Magna-UTL models. It publicly presents unit-level UL 9540A wording, string-PCS positioning, independent cluster management, liquid-cooling temperature control, flexible expansion, over-95% availability and under-four-ton unit-weight claims. The route does not define what 419/373 represent, the cell/rack configuration, nominal/usable energy, DC window/current, PCS compatibility matrix, dimensions or plant equipment. Model-number values must not be treated as kWh without a current table. Procurement should therefore retain the published identity while requesting an exact released configuration, current documents and a responsibility matrix before technical or price comparison.
Current source identity: Great Power's English product catalogue record for the DC Outdoor Battery System route for two Magna-UTL models. Published model text: Magna-UTL-419 and Magna-UTL-373. The normalized record contains no linked downloads or separate model specification table.
Current document status
Before quotation, obtain the exact model/revision and signed datasheet, complete BOM and interface drawings, current safety/compliance and transport files, operating limits, warranty and acceptance plan. Every propagation, temperature-gap, cycle-life, availability, weight and PCS-compatibility claim needs the exact configuration, test basis and responsibility boundary.
Current public product evidence
Preserve the Great Power Magna-UTL Outdoor DC Battery Systems identity and supplied-layer boundary
The catalogue text establishes a product route, but it does not by itself establish a complete orderable configuration.
Published identity
the DC Outdoor Battery System route for two Magna-UTL models; model text: Magna-UTL-419 and Magna-UTL-373.
Public positioning
unit-level UL 9540A wording, string-PCS positioning, independent cluster management, liquid-cooling temperature control, flexible expansion, over-95% availability and under-four-ton unit-weight claims
Supplied layer
The route does not define what 419/373 represent, the cell/rack configuration, nominal/usable energy, DC window/current, PCS compatibility matrix, dimensions or plant equipment. Model-number values must not be treated as kWh without a current table.
Evidence quality
Every propagation, temperature-gap, cycle-life, availability, weight and PCS-compatibility claim needs the exact configuration, test basis and responsibility boundary.
utility battery-system RFQ inputs
Six checks required for a technically comparable offer
The exact product, interfaces, site duty, evidence and contractual responsibility should be fixed together.
Project duty and guarantees
Define MW/kW, warranted usable MWh/kWh at a stated boundary, duration, C-rate, cycles/day, SOC/DoD, reserve, availability, RTE boundary, auxiliaries, degradation and end-of-life capacity.
Exact battery configuration
Require the exact released model and revision, cell/module/rack/string arrangement, BMS hierarchy, DC voltage/current window and protection. Current public identity: Magna-UTL-419 and Magna-UTL-373
Supply and responsibility matrix
Mark battery, PCS, transformer/MV switchgear, EMS/PPC, SCADA, meter, HVAC/liquid loop, fire system, auxiliaries, cables, spares, studies, installation and commissioning as included, optional or by others.
Electrical and controls interface
Provide SLD, PCS channels, AC/DC voltage, service or grid connection, fault level, grounding, protection, export/grid controls, protocols, cybersecurity and communications-loss behavior.
Site, safety and logistics
State climate, altitude/corrosion, foundation and access, fire/AHJ requirements, clearances, noise, final dimensions/weight, lifting, transport route, shipping SOC and dangerous-goods evidence.
Documents and acceptance
Request drawings, calculations, current test/certificate reports, FAT, delivery inspection, SAT, capacity/RTE/auxiliary tests, controls and safety tests, training, O&M, warranty and remedies.
Evidence, compatibility and performance boundaries
Do not turn catalogue positioning into an unconditional system guarantee
Only a configuration-matched document and contract schedule can establish measurable performance or destination acceptance.
Model text is not a complete specification
Magna-UTL-419 and Magna-UTL-373. Do not derive unstated energy, power, voltage, current, dimensions or included equipment from model numbers or neighboring Great Power products.
Public feature claims need a test basis
unit-level UL 9540A wording, string-PCS positioning, independent cluster management, liquid-cooling temperature control, flexible expansion, over-95% availability and under-four-ton unit-weight claims Require the exact model, method, boundary, environment and report or guarantee schedule before using efficiency, life, temperature, safety or availability wording in design approval.
A battery product is not automatically a turnkey plant
The route does not define what 419/373 represent, the cell/rack configuration, nominal/usable energy, DC window/current, PCS compatibility matrix, dimensions or plant equipment. Model-number values must not be treated as kWh without a current table.
Certificates and supply remain configuration-specific
A generic standard reference, catalogue page or family name does not prove report coverage, destination approval, current production status, warranty, lead time or availability. Every propagation, temperature-gap, cycle-life, availability, weight and PCS-compatibility claim needs the exact configuration, test basis and responsibility boundary.

Questions to close before product or system approval
The quotation should map every answer to one exact revision and project boundary.
What does the current public record confirm?
It confirms the DC Outdoor Battery System route for two Magna-UTL models and presents unit-level UL 9540A wording, string-PCS positioning, independent cluster management, liquid-cooling temperature control, flexible expansion, over-95% availability and under-four-ton unit-weight claims.
Does the page prove a complete orderable configuration?
No. The route does not define what 419/373 represent, the cell/rack configuration, nominal/usable energy, DC window/current, PCS compatibility matrix, dimensions or plant equipment. Model-number values must not be treated as kWh without a current table.
Can ratings or compliance be copied from another Great Power product?
No. Every propagation, temperature-gap, cycle-life, availability, weight and PCS-compatibility claim needs the exact configuration, test basis and responsibility boundary.
What should the RFQ include?
Include exact model/BOM, required power and usable energy, DC/AC/MV boundary, PCS/EMS and controls, site and safety inputs, documents, logistics, guarantees and FAT/SAT plan.
