Frequently asked questions

The questions customers ask most before they order, answered in plain English.

Do Epoch batteries communicate directly with Victron Energy systems?

Select Epoch Pro and Elite Series batteries support native CAN-bus communication with compatible Victron GX devices, including Cerbo GX and Ekrano GX. When the approved cable and settings are used, the battery can report state of charge, voltage, current, temperature, alarms, and BMS operating limits to the Victron system.

What does closed-loop CAN-bus communication do?

Closed-loop communication lets the Epoch BMS send its current charge-voltage, charge-current, and discharge-current limits to the GX device. With DVCC correctly enabled, the GX device can distribute those limits to supported Victron inverter/chargers, SmartSolar controllers, and Orion XS chargers so charging responds to the battery's real-time condition.

Do I need a Victron SmartShunt with a CAN-connected Epoch battery?

Not necessarily. A compatible Epoch battery can provide state of charge and BMS data directly to the GX device, so a SmartShunt may be optional for basic battery reporting. A SmartShunt can still provide independent current measurement, support non-CAN battery banks, or serve as the selected battery monitor in a more complex system.

Which Victron SmartSolar MPPT controller do I need?

Size the controller based on the solar array's maximum open-circuit voltage, expected cold-weather voltage, total panel wattage, battery voltage, and desired output current. The controller's PV voltage rating must never be exceeded, and its charging current must remain within the Epoch battery bank's published limits.

Can a Victron Orion charger charge my Epoch battery from an alternator?

Yes, when the Orion model, voltage conversion, output current, and charging settings are appropriate for the vehicle and battery. A DC-DC charger controls alternator demand and supplies the house battery bank with a lithium-compatible charging profile. Confirm alternator capacity, cable size, fusing, engine-detection settings, and the battery's maximum charging current before installation.

Can I monitor my Epoch and Victron system remotely through VRM?

Yes. When the Epoch battery is communicating with a compatible GX device and the GX device has internet access, supported battery and Victron system data can be displayed through the Victron Remote Management portal and app. VRM also supports configurable alarms, historical analysis, and model-specific remote controls.

What cable connects an Epoch battery to a Cerbo GX?

The required cable depends on the exact Epoch battery and communication platform. Some systems use an Epoch-supplied harness, while others require a specific VE.Can-to-CAN-bus BMS cable or approved RJ45 connection. Follow the battery manual for port selection, pinout, termination, DIP switches, and GX configuration rather than assuming any Ethernet-style cable will work.
