Anyone planning systems with Victron faces the same question again and again: which battery suits the MultiPlus-II, communicates cleanly with the GX device and is reliably available in Austria? For installers and specialist businesses we have summarised the key points – from the 48 V voltage level and CAN bus communication to DVCC. As Easyway general importer for Austria, we have already used Victron together with the 48 V batteries of the Easyway UNIV series in many systems in practice.
Why communication is decisive for Victron storage
Victron inverter/chargers such as the MultiPlus-II work with classic lead technologies as well as with lithium batteries. Lithium batteries are usually connected to a GX device via “BMS-Can” (CAN bus). Only through this connection does the system learn at which voltage and current the battery may be charged and discharged.
In practice this means: a “Victron compatible battery” is not just a question of nominal voltage. What matters is that the battery management system (BMS) talks to the Victron system via CAN bus. That is exactly what the Easyway UNIV batteries do: they communicate directly with Victron via CAN bus – using the VCTR protocol.
The building blocks: MultiPlus-II, GX device and battery
A typical Victron storage system consists of three components:
- MultiPlus-II: The inverter/charger with two AC outputs is suitable for ESS systems (Energy Storage System) and off-grid systems, among others. It can be extended in parallel and to three phases – often required for larger systems in Austria.
- GX device (e.g. Cerbo GX): The control centre of the system. This is where the battery is connected via CAN bus, the system is monitored and functions such as DVCC are activated.
- 48 V lithium battery: The battery storage with its own BMS, which reports its charge and discharge limits to the GX device.
DVCC: the battery sets the pace
DVCC stands for “Distributed Voltage and Current Control”. Activating DVCC (under Settings → System setup → Charge control) turns the GX device from a passive monitor into an active system controller.
If a battery with CAN bus BMS is connected, the GX device receives from it:
- CVL – Charge Voltage Limit
- CCL – Charge Current Limit
- DCL – Discharge Current Limit
The GX device passes these values on to the connected inverter/chargers and solar charge controllers. They switch off their own charging algorithms and follow the battery’s specifications directly. For the installer this means: the battery protects itself via its BMS, and the entire system charges the way the battery requires.
Easyway UNIV: the 48 V batteries for Victron
Victron inverters work with 48 V low-voltage batteries – which is exactly what the UNIV series is designed for. With a nominal voltage of 51.2 V, the UNIV batteries match the 48 V battery input of Victron inverters. Both 48 V models are in reliable use in many of our Victron systems:
| Model | Nominal voltage | Voltage range | Victron |
|---|---|---|---|
| UNIV 16 kWh (II) | 51.2 V | 44.8 – 57.6 V | Yes – protocol “VCTR” documented in the manual |
| UNIV 16 kWh (WP) | 51.2 V | 44.8 – 57.6 V | Yes – via CAN bus, proven in our own installations |
We have already completed many systems with Victron and Easyway – including with the MultiPlus-II. In our own installation, three Victron MultiPlus-II work with six Easyway UNIV batteries. The combination works flawlessly in practice.
You can find all details on the models on our page Victron compatible batteries.
How the Victron CAN bus battery is connected
The connection generally works like this:
- Select the protocol: On the display of the Easyway battery, the CAN protocol “VCTR (Victron)” is selected.
- Establish the CAN connection: The connection is made via CAN (CAN-H/CAN-L) to the GX device. Depending on the GX device, the VE.Can or the BMS-Can port can be configured for this – see the GX device manual for details.
- Check the cable: Observe the pin assignment according to the manual; a suitable communication cable may be required. Different cable types are available for this (VE.Can to CAN-bus BMS type A and type B) with different pin assignments.
- Activate DVCC: Switch on DVCC in the GX device so that the battery’s CVL, CCL and DCL apply system-wide.
This overview describes the general procedure and does not replace step-by-step instructions – the manuals from Easyway and Victron are authoritative. Installation and commissioning are carried out by a qualified specialist business.
Proven in practice
Easyway UNIV batteries run smoothly and reliably with the MultiPlus-II in many systems – from CAN bus communication to charge and discharge control via the GX device.
Not just Victron: Easyway with Deye and other brands
Our focus remains Deye: as Deye specialists, we have long combined Easyway batteries with Deye hybrid inverters. If you are planning Deye systems alongside Victron systems, you will find everything you need on our page Deye inverters at Involtis. In addition, the Easyway UNIV batteries work with many other inverter brands, such as SMA, GoodWe, Growatt or Sungrow – see the overview under Compatible inverters.
Delivery for installers in Austria
Involtis sells exclusively to specialist businesses – installers, electricians and specialist dealers. We deliver the Easyway UNIV batteries for your Victron system from our warehouse in Austria. For Deye systems we additionally offer our Deye support.
