Semi-Integrated Solar Street Light (EN-SSL-SI)

An off-grid street light built around a separately-mounted solar panel — angle it straight at the sun while the luminaire, lithium battery and MPPT controller stay neatly on the pole. The split design lets the panel chase the best light of the day, so even the higher-wattage models stay dependable through monsoon weeks and short winter evenings.

Eleven sizes span 9 W to 150 W, each paired to a matched LiFePO4 battery and mono-crystalline panel for two full nights of autonomy on a single good day of charge. Every unit runs fully automatic, dusk to dawn, with no grid connection and no running cost.

Why specify it

• A panel you can aim. The standalone mono-crystalline panel tilts to your site so it harvests the fullest charge each day — a real edge over fixed all-in-one fixtures.
• Safe lithium chemistry. BIS-certified LiFePO4 batteries give long cycle life and stable performance across a wide temperature band.
• Smart MPPT charging. The IEC-certified MPPT controller draws noticeably more energy from the panel than basic PWM charging.
• Wide, even light. LEDs at 120–150 lm/W with a 120°/145° spread cover roads and pathways without dark patches.
• Sealed and protected. An IP65 housing plus reverse-polarity, short-circuit, low-voltage and over-temperature protection are built in.

An on-board indicator confirms status at a glance — steady red for a depleted battery, blinking green while charging, and steady green once fully charged.
