Who this page is for
Who buys infrastructure batteries
Infrastructure procurement optimises for total cost of ownership across a fleet, not unit price. Service call-outs dominate the equation.
Buyer / 01
Solar street light manufacturers
Packs integrated into an all-in-one or split luminaire at build stage, where enclosure fit and IP rating are non-negotiable.
- IP67 metal case
- Mounting behind the panel or in the pole
- Multi-protection BMS
Buyer / 02
Telecom infrastructure contractors
Rack batteries for base-station and repeater backup, where autonomy and monitoring matter more than energy density.
- 19-inch rack format
- RS485 monitoring
- Long standby, low self-discharge
Buyer / 03
Municipal and infrastructure tenders
Fleet supply against a specification, with the documentation a public tender requires attached to the exact model.
- Consistent specification across batches
- Tender-ready documentation
- Volume planning
Why this application is different
The failure that costs money is the site visit, not the battery
A street light battery costs a fraction of the truck roll needed to replace it. That inverts the usual specification logic: over-specify the enclosure and the temperature range, accept a lower energy density, and design for the worst night of the year rather than the average.
| Design driver | Consumer logic | Infrastructure logic |
|---|---|---|
| Enclosure | Adequate for indoor use | IP67, sealed against immersion |
| Temperature range | Typical climate | Worst recorded local extreme |
| Autonomy | Average night | Longest overcast run of the year |
| Self-discharge | Rarely considered | Critical — months of standby |
| Monitoring | Optional convenience | Avoids diagnostic site visits |
| Replacement cost | Battery price | Battery plus access equipment plus labour |
Recommended platforms
Platforms specified for outdoor infrastructure
Two families: sealed packs that live outdoors on the asset, and rack batteries that live in a cabinet.
Platform / 01
Solar street light packs — IP67
Metal-cased 12.8 V and 25.6 V packs designed to mount behind the panel or inside the pole, sealed against immersion.
- 30 – 60 Ah, 384 Wh – 1.536 kWh
- IP67 metal case
- ≥ 3,000 cycles
Platform / 02
FT-B sealed series — IP64
Where the pack sits in a cabinet or housing rather than fully exposed, with higher current headroom for powered equipment.
- 12.8 V and 25.6 V
- 200 A / 400 A peak
- ≥ 4,000 cycles
Platform / 03
51.2 V rack batteries
Base-station and repeater backup in a 19-inch cabinet, with RS485 monitoring so a fault is diagnosed before anyone drives out.
- 5 – 15 kWh per shelf
- CAN / RS485
- Parallel expansion
Engineering decision points
What to specify for an unattended outdoor asset
These six points separate a fleet that runs for a decade from one that generates service tickets in year two.
01
IP67 versus IP64 — be honest about the position
IP67 withstands temporary immersion; IP64 does not. A pole base that floods, a buried enclosure or a coastal installation needs IP67. Specify the position, not the product category.
02
Design for the worst night, not the average
Autonomy must cover the longest overcast or low-sun period the site sees, plus a margin for panel soiling. Sizing to the annual average guarantees winter failures.
03
Self-discharge over long standby
Backup assets may sit at partial charge for months. Confirm the self-discharge figure and the recommended storage state of charge, and build a maintenance charge interval into the specification.
04
Temperature range at the real extreme
Desert pole-top temperatures and northern winter minima both sit outside comfortable operating ranges. Charging below 0 °C is blocked by design — for cold sites, specify self-heating explicitly.
05
Remote monitoring pays for itself
On a dispersed fleet, knowing which asset failed and why removes a diagnostic visit. RS485 or a monitoring module is usually cheaper than one truck roll per site per year.
06
Anti-theft and mechanical security
Pole-mounted and roadside batteries are theft targets in many markets. Enclosure design, fixing method and marking should be settled at design stage, not retrofitted.
Selection guide
Sizing a street light or backup pack
Multiply luminaire power by the required hours, divide by usable depth of discharge, then multiply by the autonomy days the site actually needs.
| Installation | Nightly load | Autonomy target | Suggested pack |
|---|---|---|---|
| 30 W all-in-one street light | ~0.24 kWh | 2 – 3 nights | 12.8 V 30 – 40 Ah |
| 60 W split solar street light | ~0.48 kWh | 3 nights | 12.8 V 60 Ah |
| 100 W road lighting | ~0.80 kWh | 3 nights | 25.6 V 60 Ah |
| Remote monitoring / camera site | 0.1 – 0.4 kWh | 5 – 7 days | 12.8 V 60 Ah or 25.6 V 40 Ah |
| Small repeater backup | 1 – 3 kWh | 8 – 12 hours | 51.2 V rack, 5 kWh |
| Base-station backup | 5 – 15 kWh | 4 – 8 hours | 51.2 V rack, paralleled |

Compliance for this application
Documentation for infrastructure and tender supply
Public and utility tenders usually specify the document set in the invitation. Send the tender requirements and we will confirm what we can evidence against the exact model before you commit to a bid.
- UN38.3 Test Summary and SDS for every shipment
- Dangerous goods packaging documentation for sea freight
- IP rating test evidence for the specific enclosure
- IEC 62619 test evidence where the tender requires it
- CE Declaration of Conformity for EU placement
- Consistent batch specification across a multi-year fleet rollout
OEM / ODM scope
What can be configured for an infrastructure programme
Fleet supply rewards locking the configuration early and holding it across batches. Changes mid-programme create field inconsistency.
- Enclosure format, fixing points and mounting interface
- IP rating and cable gland specification
- Capacity, BMS thresholds and low-voltage cut-off
- Self-heating for cold-climate deployments
- RS485 monitoring and remote reporting options
- Marking, asset labelling and anti-theft features
Buyer questions
Technical and purchasing questions
For a tender response or fleet quotation, send the specification document.
IP64 covers dust ingress and splashing water. IP67 withstands temporary immersion. For pole bases that flood, buried enclosures or coastal sites, IP67 is the requirement. Tell us the physical position and we will specify against it rather than assume.
The packs are specified at 3,000 cycles or more. In street lighting the battery typically cycles once per night, so calendar life and temperature exposure usually determine replacement rather than cycle count. Design the enclosure and thermal path accordingly.
Discharge operates across a wide range, but charging below 0 °C is blocked by design to prevent permanent damage. For cold sites, specify the self-heating option. For hot sites, ask for the derating position — sustained high temperature shortens life materially.
RS485 monitoring is available on rack formats and as an option on selected packs. On a dispersed fleet it usually pays for itself, because knowing which asset failed and why removes a diagnostic site visit.
Send the specification document. We will tell you clause by clause what we can evidence against the exact model, what would need testing, and what we cannot meet — including the cases where the honest answer is that we are not the right supplier.
Yes, and it should be. Lock the configuration at the start of the programme so every batch matches. If a component change becomes unavoidable we raise it before production rather than after delivery.
