  • ✅ Battery Equalizers

  • ✅ Control Devices and Electrical Panels

2. Equipment for Optimal Energy Control Onboard

A. Battery Separators

A battery separator allows multiple batteries to be charged from a single source while preventing a discharged battery from draining the energy from the others.

🔹 Operation:

  • Charges multiple batteries simultaneously.

  • Prevents one battery from discharging into another.

  • Protects and extends battery life.

Ideal for: Separating the engine battery from the service battery or managing multiple batteries onboard.

B. Voltage Converters (Step-down, Step-up, Stabilizers)

These devices are essential for adjusting electrical voltage to meet the needs of onboard equipment.

  • Step-down Converters ➡️ Convert higher voltage to lower voltage (e.g., 24V ➝ 12V).
    Usage: Powering 12V equipment on a 24V system.

  • Step-up Converters ➡️ Increase voltage to meet specific equipment requirements (e.g., 12V ➝ 24V).
    Usage: Useful for equipment that requires higher voltage.

  • Voltage Stabilizers ➡️ Maintain a stable voltage despite fluctuations in the electrical network.
    Usage: Essential for protecting sensitive equipment like GPS, radios, or onboard instruments.

C. Charge Distributors

A charge distributor evenly distributes energy from an alternator or charger to multiple batteries without them discharging into each other.

✅ Features:

  • Automatic charging of multiple batteries.

  • Optimizes energy distribution.

  • No charge loss with modern MOSFET diode models.

Usage: Essential for boats with multiple batteries (engine, service, bow thruster, etc.).

D. Galvanic Isolators

Galvanic isolators protect the boat's electrical circuit from electrolytic corrosion caused by stray currents.

🔹 Why is this important?

  • Prevents premature degradation of submerged metal parts (propeller, shaft, keel).

  • Prevents stray currents that can affect other boats in a marina.

Ideal for: Any boat regularly connected to shore power.

E. Connected Battery Management Systems (WiFi, SIMARINE)

Modern battery management systems, like those from SIMARINE, allow real-time monitoring of battery status via WiFi or Bluetooth.

✅ Features:

  • Real-time display of voltage, current, and remaining capacity.

  • Alerts for low levels or charging issues.

  • Control via a mobile app for optimized management.

Usage: Ideal for boat owners seeking precise consumption tracking and better autonomy management.

F. Battery Equalizers

A battery equalizer balances the charge between two 12V batteries connected in series on a 24V system.

✅ Features:

  • Prevents voltage imbalances between batteries.

  • Extends battery life.

  • Ensures uniform charging.

Ideal for: Boats with multiple 12V batteries connected in series for a 24V system.
