Step 1 - Understand how a Victron Energy ESS system works

Familiarize yourself with the Victron Energy ESS system.
A good place to start is to watch this video:


Step 2 - Decide what type of ESS

There are a few different ways to set an ESS system up. A combination of these are possible as well:

  • DC coupled ESS
  • AC coupled ESS
  • Energy meter is used
  • Grid parallel
  • Essential loads are used

See below drawings to get an idea of all possibilities. The first drawing shows the wiring when a MultiPlus-II is used; and the second one shows how it is wired with a MultiPlus or Quattro.

Both drawings show all AC- and DC-Coupled combinations.


Step 3 - Select the system hardware

Please see below lists. links are provided to the relevant equipment product pages

You will need:

For a DC coupled ESS you will also need:

For an AC coupled ESS you will also need:

  • Grid tied inverter
  • Solar panels

If the ESS needs an energy meter, you will need:

And one or more of the Energy Meter accessories:

To measure PV from a PV Inverter type other than Fronius, SMA or Solar edge, you will need one of these:

To equip the system with WiFi you will need:

In case of a smart battery such as BYD, you might need:


Step 4 - Install all equipment

  • Install and wire all system parts according to their manuals.
  • Do not connect communication cables between the various parts, this will be done at later stage

To find the applicable installation manuals see the links in the prevision steps. These links will direct you to the relevant product section. Then click on a the applicable product. On the product page scroll down to “Downloads”, and then select “manuals” from the drop down box.


Step 5 - Update firmware of all equipment

CCGX or Venus GX

The easiest way is to let the CCGX or Venus GX do an automatic update. This can be selected from its menu, once it is connected to the internet. Alternatively update via a SD card. For instructions how to update see: How to update Venus-OS

MPPTs Solar Chargers

Use VictronConnect; instructions are in the VictronConnect manual, section Firmware updates.

Multi and Quattro Inverter/chargers

For details, see the VE.Flash Instructions.


Step 6 - Set up parallel and/or 3 phase inverter/chargers

(skip this step if only a single inverter/charger is used)

If the ESS system contains multiple inverter/chargers, they first will need to be set up to run in parallel and/or 3 phase.

For instructions on how to do that see this manual: Parallel and three phase VE.Bus systems


Step 7 - Configure the inverter/charger(s)

The inverter needs to be configured

  • Download and install the VE Configure Tools software package from Software downloads section
  • Connect computer via MK3 interface to the inverter/charger

See this video on how to use VE.Configure:

The following settings are important:

  • Battery monitor settings
  • Charger settings
  • AC input limit settings
  • Grid settings
  • Add ESS assistant to the Inverter/charger(s)

For details, see the relevant section in the ESS Design and installation manual.


Step 8 - Connect all communication cables

  • Connect CCGX to inverter/chargers use RJ45 cable
  • Connect MPPT to CCGX use VE.direct cable
  • Connect energy meters to CCGX using the USB to RS485 interface or Zigbee units
  • Connect smart battery to CCGX, use special RJ45 cable
  • Connect CCGX to internet via Ethernet cable or WiFi module

Step 9 - Make the Venus-device settings

  • Go to ESS settings on CCGX, make ESS settings
  • Go to CanBus, select smart battery
  • Find Fronius, SMA or Solar edge on CCGX. assign correct role
  • Find current sensor on CCGX, assign correct role
  • Find Energy meter(s) on CCGX, assign correct role

For details, see the relevant section in the ESS Design and installation manual.


Step 10 - Set up VRM

  • Go to Victron VRM
  • Make a user account (in case you do not yet have account)
  • Add the system to your account
  • Check if logging is correct

For more information, refer to the VRM Portal documentation.


Step 11 - Commissioning
