Isolators, Combiners & Sensing

Accessories That Complete Your System

The Cyrix-ct 12/24V 120A intelligent combiner connects a house battery to a vehicle alternator based on voltage trend — a clean fit for 90–120A alternators, with the 230A Cyrix-i model for heavier loads. Argofet isolators charge multiple banks with minimal voltage loss; Cyrix relays are the affordable alternative for two-bank setups. The Smart Battery Sense transmits battery voltage and temperature to one or more SmartSolar MPPT chargers over a VE.Smart Network, improving charge accuracy on 12V, 24V, and 48V banks up to 10m away. For connectivity, the VE.Direct Bluetooth Smart dongle adds wireless monitoring to BMV, MPPT, and Phoenix devices.

What's the difference between a battery isolator and a battery combiner?

Both charge a second battery from your alternator. Isolators (like ArgoFET) split alternator output between banks continuously; combiners (like the Cyrix-ct) connect banks in parallel when charging voltage is present and separate them when it drops.

Can one Smart Battery Sense work with multiple MPPT chargers?

Yes — create a VE.Smart Network in VictronConnect and add each SmartSolar controller so all of them share the sensor's voltage and temperature data.

What are the cheapest Victron accessories worth buying?
