## Architectural form.
Public presence.

## 360° Panorama optics.

Inspired by the blossoming lotus flower, six precision-engineered die-cast aluminum petals radiate from the central solar hub. Integrated high-transmittance optical PC lenses project a symmetrical 360° beam pattern across a 35-meter ground diameter, eliminating dark perimeter zones across civic plazas, public parks, and commercial boulevards.

![SSL-5109 high capacity 576Wh LiFePO4 battery storage and MPPT controller architecture](https://static.tpk-led.com/images/website/tpk-led/Product/SSL-5109/ssl-5109-feature-02.webp)

## 576Wh LiFePO4 core.

Powered by an industrial-grade 3.2V 180Ah (576Wh) lithium iron phosphate battery pack paired with an integrated MPPT controller, the system maintains peak solar harvesting even during low-irradiance conditions. Engineered with over 2,000 deep discharge cycles, the power management system delivers 3 to 5 full nights of continuous dusk-to-dawn illumination.

## Modular split system.

To eliminate transit deformation across international container routes, the SSL-5109 utilizes a heavy-duty split-carton system separating the core hub from the optical petals. On site, the luminaire mounts directly onto standard Φ89 mm (3.5") poles with four stainless steel hexagonal set screws, enabling rapid contractor installation without specialized hoisting equipment.

## Frequently asked questions.

How does the fixture maintain illumination during overcast or rainy weather?

The luminaire provides up to 3 to 5 consecutive cloudy or rainy days of autonomous dusk-to-dawn lighting. Its integrated 150W monocrystalline panel recharges the internal 576Wh LiFePO4 battery pack within 6 to 8 hours of sunlight, governed by an internal intelligent MPPT controller that dynamically optimizes harvest during overcast conditions. What pole diameter is required for installation, and is the pole included?

The fixture requires a standard Φ89 mm (3.5-inch) external pole tenon for secure slip-fit mounting with four locking stainless steel bolts. The pole is not included and must be supplied separately to match project mounting height requirements (typically 6 to 10 meters, up to 12 meters). Can this luminaire be connected to AC grid power or operate on hybrid projects?

Yes. In addition to autonomous solar configurations powered by automotive-grade LiFePO4 batteries (3.2V 90Ah / 180Ah), we offer the SSL-5109-AC model. It utilizes the identical architectural die-cast aluminum housing, optical lens modules, and Φ89 mm spigot mounting system, but connects to 100–277V AC mains electricity delivering 5,980 lm. This enables landscape architects to deploy visually consistent luminaires across both solar and grid-connected areas.
