STEVAL-ILL022V1 solar-LED streetlight controller with 25 W LED
lamp driver and 80 W battery charger based on the STM32F101Rx
Introduction
The solar-LED streetlight controller consists of one 80 W battery charger and one 25 W LED
driver. During the daytime, when there is sufficient sunlight, the charger converts the
electricity from the solar panel and charges the battery. At nighttime, the battery powers on
the LED lamp as streetlight.
If it is rainy or cloudy for several continuous days, the battery will gradually run out of power.
The controller then resorts to the AC mains supply to power on the LED until the battery has
had time to fully charge again.
Main features of the solar-LED streetlight controller
■Maximization of electricity conversion efficiency from solar panel by way of maximum
power point tracker (MPPT)
■Automatic day/night/weather detection
■Automatic battery/mains switch over
■Constant current control for LED lamp
■Battery charge control
■Optional LED lighting duration mode
■Easy system monitoring via debug LED indicators
■Full protection function for OTP, OCP and UVP

1 Safety instructions
Warning: The demonstration board must be used in a suitable
laboratory by qualified personnel only, familiar with the
installation, use and maintenance of electrical systems.
1.1 Intended use
The demonstration board is a component designed for demonstration purposes only, and
shall not be used for domestic or industrial installations. The technical data and information
concerning the power supply and working conditions must be taken from the documentation
provided with the delivery, and must be strictly observed.
1.2 Installation
The installation instructions of the demonstration board must be taken from the present
document and strictly observed. The components must be protected against excessive
strain. In particular, no components are to be bent, or isolating distances altered, during the
transportation, handling or use. The demonstration board contains electro-statically
sensitive components that are prone to damage through improper use. Electrical
components must not be mechanically damaged or destroyed (to avoid potential risks and
health injury).
1.3 Electrical connection
Applicable national accident prevention rules must be followed when working on the mains
power supply. The electrical installation must be completed in accordance with the
appropriate requirements (e.g. cross-sectional areas of conductors, fusing and PE
connections).

UM0512 General description
Doc ID 14469 Rev 2 5/18
2 General description
The solar-LED streetlight controller is the key element of the system, also comprising the
solar panel, battery and LED streetlight (lamp). Figure 2 shows the structure of the system.
Figure 2. System block diagram
Each block’s function is described below.
●The sunlight delivers pockets of photons (solar energy) to the solar panel (also called
photovoltaic or PV module). The photons (energy) are absorbed by the PV module and
electrons are released.
●The electrons flow along the metal contact of the PV module and create electricity. The
battery charger then converts the electrical energy and charges the battery.
●The battery stores the electricity supplied by the battery charger. The controller
monitors the status of the battery.
●The LED lamp (LED streetlight) is activated by the LED driver. The LED light controller
monitors the system and controls the light-on and light-off in daytime and nighttime.
●When the battery goes low, the controller sends an enable signal to the mains switch
and the AC offline power supply is enabled.
The AC offline power supply (not covered in this document) acts as a backup source to
power the LED streetlight.
The solar-LED streetlight controller plays the key role in the system for electricity (solar
energy) storage control and LED lamp light-on/-off control.

4.2.4 Mains switch
When the battery is low, a high logic level output is generated by the MCU, which then
enables the mains power.
4.3 Troubleshooting
Table 5. Symptoms and corrective action
Symptom Corrective action
None of the LED(s) is
powered on. The
LED(s) include LED
lamp, debug LED and
battery status LED
– Set-up the system as per the hardware installation procedure described in Section 4.1.
– Check the mains enable signal on P6. A high logic level indicates that the battery
voltage is too low to power the LED light. This status will persist until the battery is fully
charged.
– Reset the system by pressing the reset button (PB1).
– Check the battery type and polarity. Only 12 V battery can be applied to this system. If
the battery has previously been connected reversely, replace the fuse (F1) with a new
one.
– Check that the LED lamp is available.
Battery status LED fails
to light during daytime
– Set-up the system as per the hardware installation procedure described in Section 4.1.
– Reset the system by pressing the reset button (PB1).
– Check that it is not too dark to enable the solar panel’s output.
– Check that the solar panel is available.
Dim LED lamp – Try to cool down the LED lamp.
– Check that the LED lamp’s lifecycle is still valid.
