What the systems are built to
These are the published standards the configurations above are built and tested against. They are public documents — if your tender or local authority references a different one, send it and we respond against that instead.
Certificates are held by the manufacturer of the cell, module or system and are supplied in that holder's name. We say which certificate belongs to whom rather than implying it is ours.

Questions worth asking before you order
If a supplier cannot answer these clearly, that is itself an answer.
What do you need from me to quote?
Energy in kWh and power in kW, the application, nominal voltage and whether it is AC- or DC-coupled, the duty cycle, ambient conditions, indoor or outdoor, the grid code that applies, and the delivery location. For a peak-shaving case, interval meter data changes the sizing more than anything else on the list.
Why LFP rather than NMC?
Thermal stability and cycle life. LFP has a higher thermal runaway onset temperature and degrades more slowly under daily cycling, which is what stationary duty is. NMC wins on energy density, which matters in a vehicle and rarely in a cabinet.
What cycle life should I expect?
Published figures assume conditions — usually 0.5C, 80 % DoD and 25 °C. Faster rates, deeper discharge and higher ambient all reduce it. We quote the figure with its test conditions attached, because a cycle number alone is not a specification.
Air cooling or liquid cooling?
Below roughly 200 kWh forced air is usually adequate and simpler to maintain. Above that, liquid cooling keeps cell-to-cell temperature spread within a few degrees, which directly slows degradation and is effectively standard for containers.
Do I need UL 9540A test data?
In most US jurisdictions, yes. The authority having jurisdiction generally requires 9540A results to approve the installation under NFPA 855, particularly indoors or at close spacing. Confirm it before ordering, not after.
Can you match my existing inverter?
Usually, but it has to be confirmed rather than assumed. Compatibility means the BMS and inverter agree on a protocol and the pairing is on the inverter maker's approved list. Send the make and model with the enquiry.
How is shipping handled?
Lithium is class 9 dangerous goods. Every shipment needs a valid UN 38.3 report, compliant packing and a dangerous goods declaration. Sea freight is normal for containers and cabinets; air freight is possible for small modules but expensive and restricted.
How do I spot downgraded cells?
By the data, not the label. Ask for capacity, internal resistance, OCV and self-discharge records traceable to cell serial numbers, and the maker's grading definition in writing. Cells well below market price are usually B-grade or recovered stock, and they will not balance.
What should a warranty cover?
Three things often confused: a term in years, a throughput limit in cycles or MWh, and a capacity retention figure at end of term. A warranty quoting only years tells you very little. We state all three, plus who performs service and where.
Payment and delivery terms?
Quoted per order against incoterms and destination. Lead time, terms and the applicable incoterm are stated in writing on the quotation before anything is confirmed.
