Victron Marine Battery Isolators: Power Separation for Ultimate Reliability at Sea

Ensure the safety, longevity, and reliable operation of your marine electrical system with our range of Victron Marine Battery Isolators. Designed specifically for the challenging demands of the marine environment, these essential devices intelligently manage power distribution between your battery banks, protecting your critical systems and guaranteeing you always have starting power.

What is a Marine Battery Isolator?

A marine battery isolator is a smart device that allows a single charging source (like an alternator, shore power charger, or solar controller) to charge multiple independent battery banks without connecting them directly. This crucial separation means that a discharge from one battery bank (e.g., your house bank powering lights and appliances) cannot drain your other battery banks (like your engine starting battery).

Why Are They Essential for Your Boat?

On a boat, dependable power is non-negotiable. Victron Marine Battery Isolators provide peace of mind by:

• Protecting Your Starting Battery: Guaranteeing that your engine's starting battery remains fully charged and isolated from your service (house) batteries, so you can always start your engine, even if your house batteries are depleted.
• Preventing Cross-Discharge: Eliminating the risk of one battery bank discharging into another, preserving the health and charge of each individual bank.
• Safeguarding Electronics: Isolating sensitive electronics from potential voltage fluctuations or dips caused by heavy loads on other battery banks.
• Optimizing Charging: Many Victron isolators feature low voltage drop designs, ensuring that almost all of your charging current reaches your batteries efficiently.
• Enhancing Safety: A well-managed electrical system reduces risks and contributes significantly to overall vessel safety.

Our Victron Marine Isolator Range

Victron Energy offers a variety of advanced battery isolator technologies to suit different marine setups:

• Argo Diode Battery Isolators: A robust, reliable solution that allows simultaneous charging of multiple batteries from one alternator, while ensuring they remain isolated. They are known for their simplicity and durability.
• ArgoFET Battery Isolators: These 'FET' (Field Effect Transistor) isolators offer an even lower voltage drop compared to diode isolators, resulting in more efficient charging and less heat generation. They are ideal for maximizing charging performance.
• Cyrix Battery Combiners: Intelligent battery combiners that automatically connect batteries in parallel when a charging source is present and disconnect them when charging stops. This ensures full charging for all batteries without allowing them to discharge into each other. Perfect for dynamic charging needs.
• Cyrix-Li-Charge: Specifically designed for safely connecting a lead-acid starter battery to a Lithium (LiFePO4) service battery, providing a controlled charging path without overcharging or compromising either battery type.
