Lithium batteries sized for the complete solar street-light duty cycle.
Battery-only OEM support for street-light manufacturers, integrators and project buyers—based on lamp power, dimming schedule, solar input, autonomy, controller and installation environment.
Calculate nightly energy first, then add real-world system constraints.
A solar street-light battery cannot be sized from lamp wattage alone. The duty profile must include full-power and dimmed hours, controller and conversion losses, seasonal solar resource, required autonomy, allowable depth of discharge, temperature and end-of-life reserve.
System voltage, photovoltaic controller limits, enclosure location and the charging window determine the battery architecture and BMS requirements. We supply the battery component; the lamp, solar panel, pole, controller and civil installation are not included unless separately confirmed.
Seven inputs prevent a misleading Ah recommendation.
Nightly load
Calculate watt-hours from each lighting and dimming period, not nameplate power alone.
Autonomy
Add the specified number of low-sun nights and a defensible reserve.
Solar recharge
Check worst-season solar input, controller limits and available daily recharge time.
Environment
Derate or control charging/discharging for temperature and enclosure conditions.
| Lamp profile | Power at each dimming level × hours, plus controller/conversion losses. |
|---|---|
| Energy reserve | Autonomy target, permissible operating window and end-of-life capacity margin. |
| Battery voltage | Matched to controller, LED driver and charge/discharge voltage limits. |
| BMS/current | Load current, controller behavior, low-temperature charging, protection and service disconnect. |
| Mechanical | Space, mass, pole/base/underground enclosure, sealing, condensation, connector and theft/maintenance access. |
| Commercial | Project quantity, forecast, packing, destination, shipment mode and required model documents. |
Before selecting a battery.
What battery capacity does a solar street light need?
It depends on the timed lamp profile, system losses, autonomy, seasonal recharge, operating window, temperature and aging margin. Provide these inputs for a defensible capacity.
Is LiFePO4 suitable for solar street lights?
It is a common candidate, but the exact cell, charging behavior, temperature controls, enclosure and lifecycle target must be matched to the project.
Do you supply the complete solar street light?
This page is for battery supply and battery integration review. Lamps, panels, poles, controllers and installation are outside the default scope.
