Detailed description
Detailed description
The Victron Energy Blue Smart IP67 Charger 12/25 (1+Si) is a robust charging solution designed for marine and demanding environments. It features an IP67 rating, ensuring complete protection against water, oil, and dirt. Its die-cast aluminum housing and electronics encapsulated in resin provide shock resistance.
Performance and Energy Efficiency
This model delivers 95% efficiency, minimizing heat dissipation. Its standby power consumption is 0.5 W. It includes a 5-step adaptive charging algorithm (bulk – absorption – conditioning – float – storage) to optimize lead-acid battery lifespan. The storage mode reduces float voltage to 13.2 V (for a 12 V battery) after 24 hours of inactivity, with weekly equalization to prevent stratification and sulfation. The charger is also compatible with Li-ion batteries, using a simple bulk – absorption – float algorithm.
Advanced Features and Connectivity
The Blue Smart IP67 Charger 12/25 (1+Si) features Bluetooth Smart connectivity, enabling monitoring of voltage and current, parameter adjustments, and updates via the VictronConnect app. It includes a recovery function for fully discharged batteries, capable of initiating charging even at zero volts. Overheat protection adjusts output current if temperature exceeds 40 °C, without failure up to 60 °C. This specific model (1+Si) includes a second limited-current output of 0.5 A, with output voltage no more than one volt below the main output, intended for a start-interrupt function.
