C&I energy storage
Move from interval-load data and operating objectives to power, usable duration, cooling, site constraints, and a comparable proposal.
Technical resources
Technical guides for better battery and energy-storage decisions
Size residential storage, compare battery formats, review BESS cooling and safety, and prepare a clearer project RFQ.
Start from the buying decision
Four paths from technical question to project review
Each path connects an application, suitable product families, decision guides, supporting documents, and the next information needed for a proposal.
Utility and renewable storage
Define generation, dispatch, connection, duration, battery-side limits, AC balance of system, and project responsibility boundaries.
OEM and ODM battery programs
Control the application brief, specification, interfaces, validation, documentation, packaging, release, and future changes.
Residential solar and backup
Define critical loads, backup duration, solar recharge and inverter compatibility before comparing rack, stacked, wall-mounted or integrated systems.

Guides for project planning
Each guide focuses on a decision buyers need to make before comparing models, requesting documents, or asking for a quotation.

C&I BESS Sizing Guide
A defensible C&I battery energy storage system size comes from interval load data, a ranked operating objective, power constraints and usable energy at a stated measurement point. Start with the duty the site needs, then evaluate the cabinet or container configuration against it.
Read guide →selection guide
Home Battery Sizing
Size a home battery from the loads that must run, their coincident and starting power, required backup hours, usable-energy assumptions, recharge opportunity, and the inverter's supported battery configuration.

Air vs Liquid Cooling
Air and liquid cooling are system-level choices. Compare heat density, temperature uniformity, ambient conditions, parasitic demand, acoustic limits, maintenance, fault response, and site layout—not capacity alone.

BESS Safety Review
A BESS safety review should connect cell and module behavior to electrical protection, BMS controls, thermal management, enclosure, fire strategy, emergency response, site layout, installation, and operating procedures.

Solar Battery Decision Guide
A solar battery is worth evaluating when it supports a defined objective that can be modeled from interval loads, solar production, outage needs, export limits, tariffs, and operating constraints.

Home Battery Formats
Rack, stacked, and wall-mounted batteries mainly differ in mechanical format, expansion method, service access, footprint, cable routing, and integration. Energy needs and inverter compatibility remain the first filters.

DC Container vs AC BESS
A battery container's MWh rating does not define a complete grid-connected AC energy storage system. Separate the DC battery boundary from PCS, transformer, switchgear, controls, civil works, installation, commissioning, and acceptance before comparing proposals.

BESS RFQ Checklist
A useful BESS RFQ states the operating objective, site data, power, usable energy, duration, electrical interface, environment, safety requirements, scope split, documents, and acceptance criteria.

Nominal vs Usable Energy
Nominal energy is a nameplate quantity. Usable energy must be stated for a defined operating window, duty and measurement point. Energy available at battery terminals and net energy delivered at a site's AC connection are different quantities. Comparing proposals requires the same boundary and conditions.

Technical procurement briefs
Model-specific specifications, operating boundaries and RFQ inputs. Confirm the applicable configuration and controlled technical documents with your quotation.
Turn the guide into a project brief
Use the checklist and then send the actual load, application, site, interface, destination, and schedule for review.
