Victron BlueSolar Light 48-20 20A PWM Charge Controller
Modelo: BlueSolar Light 48-20- Sku: VICTREG049
- Vendor: Victron
Specifications
Product Description
The Victron BlueSolar Light 48-20 20A increases the capacity of the PWM-Light range to 48 V to cover applications with higher consumption without sacrificing simplicity. It maintains the PWM control philosophy with three-stage charging, comprehensive protection, and output with low voltage disconnect to prevent deep discharges. It incorporates a practical lighting control with day/night detection and timer, manageable from the seven-segment display. Its common positive architecture and low self-consumption facilitate integration into compact panels and maximize the system's usable energy.
Main Features
- 20 A charging current for 48 V systems.
- 3-stage algorithm: initial 58.0 V, absorption 56.8 V, and float 55.2 V.
- Battery protection: LVD at 44.8 V with reconnection at 50.4 V (manual) or 52.4 V (automatic).
- Maximum PV voltage allowed 100 V, self-consumption <10 mA.
- Lighting control: day/night mode with timer configurable from the display.
- Electronic protections against reverse polarity, overload, short circuit, and overtemperature.
Advantages or Benefits
- More current margin than the 10 A model, maintaining a contained cost and very simple operation.
- Longer battery life at 48 V thanks to stage management and precise low voltage disconnect.
- Automates solar lighting without additional controllers, reducing components and installation time.
- Clear interface with LED display and 6 mm² terminals for quick installation and minimal maintenance.
- Compact and lightweight format suitable for cabinets with limited space.
Purpose or Applications
Ideal for public or residential lighting at 48 V, signage and signaling, remote stations with moderate loads, small industrial or telecom installations, and auxiliary systems where a robust and efficient PWM regulator is the preferred option.
