ESS Quick Installation Guide

This quick installation guide lists all the steps that are needed to install and configure a Victron Energy ESS system. It briefly explains each step. It also provides links to locations where more in depth information about each step can be found.

The full ESS manual can be found here: design-installation-manual

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:

Note: This information does not apply to the Multi RS models, which use a VE.Can interface (not VE.Bus) see the RS product manuals for specific information on programming them for ESS.

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 power coming from a grid-tie PV inverter of a type other than Fronius, SMA, ABB 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

GX device

The easiest way is to let the GX device (Cerbo 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 a GX device

Inverter/chargers and MPPT Solar Chargers

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

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, split- 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 GX device to inverter/chargers use RJ45 cable
  • Connect MPPT to GX device use cable
  • Connect energy meters to GX device using the USB to RS485 interface or Zigbee units
  • Connect smart battery to GX device, use special RJ45 cable
  • Connect GX device to internet via Ethernet cable or WiFi module

Step 9 - Make the GX device settings

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