Solar Street Light Solutions
Controller solutions across the full platform range — 30W garden lights to 160W main roads
Challenges
No guaranteed runtime on consecutive cloudy days?
Batteries over-charged and over-discharged, short lifespan, frequent maintenance?
Inflexible dimming, no precise time-segment brightness control?
Unsure how to size batteries and PV panels correctly?
System Components
Solar PV panel (6V single-cell / 18V 4-cell)
MPPT/PWM smart controller (boost/buck + constant-current drive)
LiFePO4 battery (3.2V single-cell / 12.8V 4-cell)
LED street light (3.2V flat / 9–36V boost constant-current)
Recommended Products
Garden & Landscape (20–40W)
MPPT boost IR controllers, 13A/16A charging, compact and reliable
Secondary Roads (60W)
25A high-current, Bluetooth-tunable, or boost light-source drivers — flexible configurations
Main Roads (80W)
30A charging, 80W output, Bluetooth or IR variants
High-Power Arterials (120W+)
40A charging, up to 160W output on the 12.8V 4-cell platform
Solution Highlights
- MPPT tracking efficiency ≥99%, charging conversion up to 97%
- Built-in coulomb counter plus AI algorithm for reliable runtime on cloudy/rainy days
- Designed for single/4-cell LiFePO4 — no battery protection board needed, lower PACK cost
- 8-segment dimming with adaptive dawn boost; tuning via Bluetooth, IR or mini-program; OTA upgrade
- IP65-rated aluminum housing, -40°C to 80°C operation in harsh environments
- Complete protection: overcharge/over-discharge, reverse-polarity, PV short-circuit, LED open/short-circuit, over-temperature
Selection Guide
Determine LED power: e.g. a 60W light → choose the 60W output tier
Estimate battery capacity: power × runtime × 2 margin ÷ system voltage (e.g. 60W×10h×2÷3.2V ≈ 375Ah)
Choose system voltage: 3.2V single-cell for low/mid power, 12.8V 4-cell recommended for ≥80W
Size the PV panel ≈ daily energy (Wh) ÷ peak sun hours ÷ system efficiency (~0.8). E.g. 600Wh ÷ 4h ÷ 0.8 ≈ 188W (battery capacity already includes the cloudy-day margin — do not multiply it again)
Check charging current: controller rating ≥ PV short-circuit current (see spec table)
