The BlueSolar PWM-Light 12/24V-20A is a basic, reliable, and energy-efficient solar charge controller with support for automatic 12/24 V voltage detection. Thanks to its simple operation, lighting timer support, and built-in protections, it is well-suited for small-scale off-grid solar systems.
Key Benefits
- Automatic system voltage detection (12 V or 24 V)
- Three-stage charging algorithm: Bulk, Absorption, Float
- Load output with automatic shutdown function when the battery is low
- Protections: against reverse polarity, short circuit, overload, and overheating
- LED display for quick lighting mode adjustment
Technical features
- Maximum charging current: 20 A
- Maximum solar panel voltage: 28 V (for 12 V systems) / 55 V (for 24 V systems)
- Self-consumption: less than 10 mA
- Operating temperature range: from -20°C to +50°C
- Humidity: up to 95% (non-condensing)
- Protection class: IP20
Off-grid lighting control
The controller supports a lighting timer (day/night function), which activates or deactivates the load depending on the ambient light level. It is ideally suited for street, park, or camping lighting where lights need to be turned on only during the dark hours of the day.
- 1 lighting timer (time is set manually via the indicator)
- Load mode indication via a two-digit seven-segment display
Application scenarios
- Standalone lighting systems: garden lights, park lanterns, security lighting
- Mobile applications: campers, summer cottages, mountain huts, field posts
Communication and monitoring interfaces
- User interface: built-in two-digit seven-segment display
- Manual load control via a button on the housing
- Timer settings are configured via the display—no computer or Bluetooth required
