- Vendor: Victron
Specifications
Product Description
The Victron BlueSolar LCD&USB 48-20 20A increases the capacity of the LCD&USB series in 48 V systems, maintaining a robust, efficient, and very easy-to-use PWM design. It provides up to 20 A charging current, integrates an LCD screen for local parameterization and diagnostics, two 5 V USB ports (2 A total) for auxiliary loads, and a complete day/night timer for solar lighting. Three-stage charging management preserves the battery, while the output with low voltage disconnect (LVD) prevents deep discharges. Its common positive, self-consumption below 10 mA, and compact format simplify integration in professional or DIY panels.
Main Features
- 20 A at 48 V for installations with larger PV area or higher continuous loads.
- LCD screen for voltage adjustment, LVD, and timer; immediate status reading.
- 3-stage algorithm: initial 58.0 V, absorption 56.8 V, and float 55.2 V.
- LVD 44.8 V with manual reconnection at 50.4 V or automatic at 52.4 V.
- USB 2×5 V (2 A total) and integrated day/night lighting control.
- Max PV (Voc) 100 V, common positive, IP20, and self-consumption <10 mA.
Advantages or Benefits
- Extends the life of lead-acid batteries at 48 V with precise voltages and reliable LVD.
- Reduces costs and complexity by integrating timer and interface in the controller itself.
- Quick installation with terminals up to 6 mm², lightweight format, and simple menus.
- Ideal for upgrading lighting and signage to 48 V without adding additional controllers.
- Low internal consumption maximizes the energy available for loads.
Purpose or Applications
Recommended for public/residential lighting at 48 V, signaling, remote telemetry stations, auxiliary telecom, marine/camper with 48 V battery bank, and small industrial installations where reliability and simple operation are prioritized.
