    Preliminary remarks

    • The installation and configuration of the VARTA energy storage system may only be carried out by certified electricians in accordance with the specifications of VARTA AG. Certification training is a prerequisite for installation and warranty.
    • VARTA element S5 backup with a serial number < 127101623 require a firmware update.
      Contact VARTA Technical Support (+49 9081 240 - 86 6044; technical.service@varta-storage.com) after successful commissioning in accordance with VARTA's certification training and before connecting to the EnergyManager pro and have the firmware update installed.
    • Simultaneous control of system components (inverters, loads) by the EnergyManager pro and the VARTA energy management system leads to system malfunction. Therefore, only control the system via the EnergyManager pro.
    • The use of a VARTA storage system in combination with the SOLARWATT Manager requires the installation of one of the following 2-directional meters in addition to the VARTA Split Core Sensor:

    • Install the 2-directional S0 meter directly behind the EVU meter. Ensure that the phases are in phase.
    • connect the 2-direction S0 meter to the EnergyManager pro via the S0 data cable.

    Example in the illustration: Connection terminals on the KDK PRO380-S

    L1 (in)Phase 1 input (mains)
    L1 (out)Phase 1 output (house)
    L2 (in)Phase 2 input (mains)
    L2 (out)Phase 2 output (house)
    L3 (in)Phase 3 input (mains)
    L3 (out)Phase 3 input (house)
    N (in)Neutral input (mains)
    N (out)Neutral output (house)
    18/19Pulse output (S0) "Reference" +/-
    20/21Pulse output (S0) "Supply" +/-
    • Install the VARTA Split Core current sensor on the top-hat rail in the switch cabinet. Follow the Installation instructions from VARTA (mandatory requirement: VARTA certification training).
    • Restore the power supply.
    • Connect the VARTA energy storage device to the VARTA Split Core current sensor via the sensor cable (included in the scope of delivery of the VARTA energy storage device).
    • Connect the VARTA energy storage system to the customer network via Ethernet (LAN data cable; RJ45 plug).
    • Configure the VARTA energy storage system in accordance with the VARTA operating instructions. You will receive the documents at the VARTA certification training course.
    • Assign a static IP address to the VARTA Energy Storage System via the router's user interface.

    Installation with 1-direction S0 meter as main meter (mains side)

    Interface: S0 input

    • Establish a disconnect and check it.
    • Install the main meter (1-direction S0 meter) between the connection point of the PV system and VARTA energy storage system and the other domestic consumers (see wiring diagram below)
    • Ensure the correct installation direction according to the wiring diagram
    • Install the VARTA Split Core current sensor and the feed-in points of the VARTA energy storage system and PV system between the main meter and the utility meter on the grid side.
    • The individual components must be connected in series. Note the phase equality and the clockwise rotating field.
    • A 1-directional S0 meter or the KDK meter (KDK PRO380-S) can be installed for this setup. When using a KDK counter, only one S0 connection may be used according to the installation direction. When installing S0 meters, generally pay attention to the correct installation direction.

    *) Assignment of a static IP address (via network settings VARTA or router settings) recommended.

    **) Shelly devices are found after starting the device search without specifying an IP address. If the IP address of the Shelly is changed at a later date, the connection is lost and a new device search is required. It is therefore recommended that Shelly devices are assigned an unchangeable IP address.
