Sleek, timeless,
built to last.
The flat-profile all-in-one: panel, battery, optic and IoT node in one slim casting, with the light engines recessed into the underside. Solara I covers 20–90 W, Solara II 100–200 W, and both report to the same cloud — no trenching, no cabling, no electricity bill.
How a solar light
gets through a night.
Three poles on one kerb of a four-lane carriageway, spaced at 3.5× mounting height so the throws cross and the road lights evenly. Jump to sundown or sunrise and watch the photocell hand the street over — or take the switch and the dimmer and drive all three yourself.
Made on the pole,
kept in the pole.
A solar light is an energy budget with a lamp on the end of it. The panel sets what comes in on a short winter day; the pack decides how many of those days the light can miss and still work. Both are sized per model — the table under Specification carries the per-model figures.
Monocrystalline, multi-busbar
Multi-busbar monocrystalline cells at 23% conversion, 24% at module level, with output held to ±3%. PID-resistant and tested to IEC 62804, rated to 18 V or 36 V, and warranted 10 years on materials against a 25-year linear output curve — longer than the pole is usually specified for.
LiFePO₄, Grade A+ cells
E-Lite builds its own packs, and a pack is not a box of cells with a lid on it. More than 4000 cycles, with two cell grades: standard cells charge from 0 °C, and advanced cells charge down to −20 °C for winter sites where a standard pack would simply refuse. Both discharge across the full −20…60 °C range. Capacity is measured and real, not estimated, and maintenance is guaranteed for 5 years.
Harvest by day,
control through the night
The MPPT controller tracks the solar panel's maximum power point as conditions change, with tracking efficiency above 99.9% and charge conversion of 97.5%. Charging moves through MPPT, boost, equalisation and float to replenish the pack for the night ahead.
After sunset, the controller sets how that stored energy becomes light. Choose a mode to see the difference: five timed brightness steps, a response to movement, one level from dusk to dawn, or a schedule counted back from the recorded sunrise. Controller B supports five-stage and motion-sensor modes; Controller C supports five-stage, dusk-to-dawn and TOT. The schedules shown are examples.
The controller’s clock steps the level from block to block. Traffic changes nothing in this mode.
The sensor raises the level the moment it sees movement; after a short delay it falls back.
After the panel’s voltage crosses the day/night threshold (D/N Thr) the light waits a short delay (D/N Dly) — at dusk and again at dawn — so a passing cloud does not switch it.
TOT (dashed) and Time 5 are counted back from the sunrise the controller recorded the day before, so Time 5 ends as the sun comes up on a short night and a long one. Times and levels are an example.
A Tiltable Light
Where the light lands is set on site, not in the factory, and this head carries two joints that move independently. The travel quoted here is the figure the slider stops at — the fixture's rated travel, or what the head actually clears on the pole where that is less.
- LED moduleEach LED module hinges on its own mount through ±30°.
- The fixtureThe whole head then swings on the slip fitter's knob, independently of the engines, as far as it is rated or until it would meet the pole, whichever comes first.
The Optics
How efficiently the engine makes light, and how tightly the optic cuts it. Both are specified rather than set on site: the beam is shaped at the LED, and which of the distributions a pole is built with is a different lens plate, not a setting.
Up to 220 lm/W, IP66
Experience superior brightness and rugged reliability. Powered by high‑output Philips Lumileds, the 1–4 module design ensures over 100,000 hours of high‑efficacy lighting. Built to withstand the harshest environments, the unit carries an IP66 ingress protection rating and IK08 impact resistance.
Eight optimized optics
meeting diverse road requirements
To ensure optimal visibility and safety across any landscape, the system offers eight precision‑engineered optics tailored to diverse road requirements. This selection spans IESNA Type I through Type V distributions, covering everything from narrow pedestrian walkways and urban streets to multi‑lane highways and expansive parking areas. These optimised optics direct high‑efficiency illumination exactly where it is needed, eliminating dark spots and minimising light waste.
Each array, as supplied. Each dimple is one LED's optic and the plate is a single moulding, so the pattern cannot drift out of alignment on site, and the IP66 rating is guaranteed.
- 60×100°Type I-VS
- 65×145°Type IV-S
- 65×155°Type II-M
- 70×135°Type II-S
- 75×150°Type III-M
- 80×150°Type III-S
- 110°Type V-S
- 150°Type V-S
Left: how the light leaves the luminaire. Intensity in candela against the angle from straight down, in the plane across the carriageway (C0–C180) and along the road (C90–C270). Almost nothing is thrown behind the pole, which is what keeps the light on the road instead of in the windows facing it.
Right: what that puts on the ground. Set the mounting height and the pattern redraws: colour shows relative brightness, the contour lines are absolute lux, and the kerb and a 7 m carriageway give the scale.
The Type III-M is one of the eight distributions listed above — the same luminaire, a different lens for a different road.
Everything it knows,
and who it tells.
From here on it is the same pole seen from further away: the node that runs it, the six things it senses about itself, the CMS it reports to and the mesh it reports over.
Flexible IoT Connectivity Architecture
The IoT node supports mesh‑network variants in both NEMA‑type and Zhaga‑type form factors. It also offers star‑network options, including the 4G‑enabled NEMA‑type model and E‑Lite’s own embedded in‑house design.
What the light knows
about itself
Six of them, and not one is decoration. The light switches on its own panel voltage, counts the charge in and out of its pack, knows if it has been leaned on, and refuses to charge a frozen battery. What they measure is what the console shows — there is no second, friendlier set of numbers.
Dusk to dawn
The panel is the sensor: the controller switches on the falling panel voltage against a programmable 5.0–10.0 V threshold, with a 0–30 minute delay so passing cloud does not cycle the light.
Two power levels
In motion mode the light holds 100/60/30/70% while something is moving and drops to 30/20/10/20% when nothing is — the saving that buys the small hours without leaving a street dark.
Measured, not modelled
A high-precision battery monitor module reports voltage, current, power, real capacity and time remaining. A pack that is ageing shows up as a falling capacity years before it shows up as a dark pole.
Permanently powered GPS
A mini tracker hidden in a part of the battery pack an installer cannot reach, followed live from the app. It is there for the battery packs that leave site on the back of somebody’s truck.
Gyroscope and accelerometer
The installed angle is locked at commissioning. A knock, a lean or an attempt to unbolt the head raises an alarm at the operation centre and sends an SMS from the management system.
0 °C charge protection
Standard lithium is not charged below freezing. The controller holds charge off until the pack is warm enough to take it, which is the single thing that most shortens a solar light’s life in a cold climate. So we suggest the premium lithium pack for low-temperature areas.
One console
for the whole estate.
A cloud central management system for provisioning, monitoring, controlling and analysing lighting. Multi-tenant, reached from a browser on a laptop, tablet or phone, and scaling to thousands of locations under a single interface.
The console runs
on its own page.
A working simulation of the platform E-Lite ships with iNET, rebuilt screen by screen from the live console. Every rail item, filter, dropdown, toolbar icon, page control, row action, drawer and log tab responds the way it does in the real thing — so you can evaluate how an estate is actually run before committing to anything. Nothing writes, and every name, reading and coordinate on screen is invented.
- Provision and monitor — every light and gateway, on a map or in a list.
- Control — on, off, dimmed, by hand or on a schedule, singly or by group.
- Alarms — lamp failure, night outages and day burners, to e‑mail or SMS.
- Reports — energy and light level by asset, selection or city.
Every light, on the map
Create, import and edit device attributes — fixture coordinates and type, fixture wattage before and after retrofit, lamp type. iNET performs GIS‑to‑GPS matching to correlate fixture IDs with physical devices, so device IDs need not be recorded during installation.
Map and floor plan
A map-based interface for status, health and overrides, extended to floor plans for indoor structures such as parking garages. Faulty devices are located from the same view that reported them.
Groups and priority
Assets group logically for event scheduling, and a group can hold several schedules at once — regular and special events kept apart, with the engine resolving the day from event priority rather than from the operator remembering.
Collected several times a day
Light level, energy use and faults, with per-point monitoring levels for voltage, current and power factor when a circuit needs investigating.
Failure finds you
Built-in alarms per asset class, configurable to e-mail and SMS. The system watches for lamp failure, night outages and day burners, and the logs export as CSV.
Asset, selection or city
Energy reports compare performance across lighting assets; data logs trend light level, wattage and schedules over a period. Everything exports to CSV or PDF.
Every interface to iNET uses SSL with AES encryption. Access is role-based and can be restricted at different levels of a geozone hierarchy, password policy follows industrial standards, and a timeout after repeated failed logins closes the obvious attack.
Multi-tenant and built on current web technology, so it ports across platforms and web interfaces. Supported on Chrome, Firefox and Edge.
Every node
relays for its neighbours.
The gateway talks to the server over 4G cellular, and to the nodes over SUB-1GHz radio. Between the nodes it is a mesh: any node can act as a repeater, so an instruction from the server reaches a light that cannot hear the gateway directly.
SUB-1GHz, nine channels
IEEE 802.15.4 on ISM 315 / 433 / 490 / 868 / 915 / 928 MHz, 9-channel direct sequence spread spectrum at +22 dBm from the node and +24 dBm from the gateway. Node to node and node to gateway both reach 1 km line of sight.
Wireless
It leverages its integrated 4G modem to connect over any cellular carrier. Downstream nodes operate independently and remain unaffected regardless of the gateway’s connectivity method.
100–200 nodes, 2000 m across
One gateway carries up to 200 controllers out to 1000 m line of sight, and the mesh between them spans a network up to 2000 m in diameter. Beyond that, add a gateway rather than a trench.
A gateway.
A node per light.
Two devices carry the whole system. The gateway is the bridge to the server; the node is the part that actually holds a luminaire's behaviour, and there is one in every fixture.
The bridge to the server
Connects the field controllers to the management system over 4G, through an integrated cellular modem. Star-mesh repeater topology, wall or pole mounted, with a built-in lightning surge arrester on every antenna port and a 5-year limited warranty.
Two ways to fit it
Standard installs inside the fixture, normally in the drive box — the choice for new luminaires and for retrofits where the housing opens. Node fits the NEMA 7-pin socket on top of a street light or area fixture, with an onboard photocell, and needs no one inside the housing at all.
