Ective in your camper: integrating battery, inverter and DC-DC charger into Camper Jarvis

Updated 27 October 2026EctiveVolty

In short

Ective devices with a CAN interface can be integrated directly into Camper Jarvis: LC lithium batteries, the CSI PA PRO inverter/charger, and DC-DC chargers and solar charge controllers with CAN. Volty Pro reads them and shows state of charge, currents and fault messages on the SmartKnob and in the dashboard. There you also switch the inverter on and off and limit its input current.

Do you have Ective devices in your camper, for example an LC lithium battery, the CSI PA PRO inverter/charger or a DC-DC charger with CAN? With Camper Jarvis you see their values where your heater, lights and water are too: on the SmartKnob and in the dashboard on your phone or tablet. The devices are read by Volty Pro, directly through their CAN interface.

Which Ective devices work

Device What works
LC batteries with CAN, for example LC-S and NaC State of charge, voltage, current and further data from the BMS
CSI PA PRO inverter/charger Read values and fault messages, on and off, limit the mains input current from 1 to 16A
DC-DC chargers and solar charge controllers with CAN Read values
Triple (new generation) In progress

Only Ective devices with a CAN interface have a data connection. Models without an interface cannot be read. You always find the current status in the energy compatibility list.

What you need

  • A SmartKnob as the central unit.
  • A Volty Pro, paired with the SmartKnob. How pairing works is explained in Pairing modules with the SmartKnob.
  • For Ective LC batteries the Victron cable VE.CAN to BMS Type A: the Victron end goes into Volty, the BMS end into the battery.

What you get

  • Everything in one place: the battery's state of charge next to solar, heater and tanks. No switching between apps.
  • The inverter with a turn and a press: on, off and the input current to match the fuse at your pitch.
  • Mixed systems: an Ective battery with a Victron solar charge controller? Volty Pro reads Ective via CAN and Victron via VE.Direct and shows everything together.
  • Local in the vehicle: everything runs without internet and without cloud. If you have internet on board, you can still use it.

Related questions

Is a simple voltage display enough for the battery?

For a lead-acid battery at rest it gives you a rough idea. For lithium batteries, and for decisions like “will it last until tomorrow?”, it isn't enough, because the voltage hardly changes between about 20% and 90% charge. For that you need a battery monitor or the data from the BMS, which Volty Pro shows you on the SmartKnob.

Do I have to replace my existing power devices?

No. Volty Pro reads your existing devices through their interfaces, and the right cables are included. Whether your device is already supported is shown in the power compatibility list in the knowledge hub.

What can Volty Pro read?

Volty Pro brings your whole energy system together in one place. It reads battery monitors, lithium batteries with CAN, solar charge controllers, chargers, inverter/chargers and DC-DC chargers (battery-to-battery chargers). It connects through each manufacturer's data ports: • Victron via VE.Direct and VE.Bus • Ective via CAN • EcoFlow via the EcoFlow Power Link • Votronic via LIN We are working on smart BMS such as Daly, JK or JBD. Which devices already work today is shown in the [Energy compatibility list](/blogs/wissen/kompatibilitaet-energie). Instead of a separate app or display for every device, you see state of charge, solar yield and consumption together on the SmartKnob and in the dashboard, even with a mix of many manufacturers. So you can pick the best from each manufacturer and still have everything in one place.

Do I have to buy the data cables separately?

No, Volty Pro comes with a ready-made cable set for all data ports, included in the box. You do not need to buy anything separately. Only where a manufacturer such as Victron or Votronic specifies its own original communication cable do you use that one, because it is part of the connection the manufacturer has specified.

Can Volty monitor a second battery?

Yes, the second voltage input (Battery 2) lets you keep an eye on an additional leisure battery. Important: this input is intended exclusively for additional leisure or house batteries, not for the starter battery or the vehicle's primary electrical system. That is outside the product specification.

Can I switch my inverter on and off via Volty?

Yes, if your inverter has a remote on/off connection or switching on and off is built into its data interface, as with the Victron MultiPlus or the Ective CSI Pro, for example. Volty Pro has a 2-pin remote output for this. It lets you switch the inverter on and off directly from the dashboard or the SmartKnob, without getting up.
