Guided Configuration

Introduction

The Configuration Wizard (also called the configuration “Wizard”) is the procedure that guides the user in configuring the parameters of Prism after finishing its installation.

Guided Configuration

After powering up Prism, make sure there are no error LEDs, then proceed with the configuration wizard.

In the case of red LEDs, refer to the “LEDs” section to check that the installation was done properly.

Access the Configuration Wizard

To access the wizard, you need to connect to the Prism WiFi network and visit the configuration page.

  • Connect to Prism’s Wi-Fi network. In case you are using a smartphone, turn off the cellular data network as a precaution.
The WiFi network name and password can be found in the credentials label located in the manual that came with Prism.

  • Once connected, open the browser and go to the page http://192.168.8.1/ and press on Settings (from Smartphone, open the drop-down menu in the upper right corner)
  • On the login page, enter the “installer” credentials.
The “installer” credentials can be found in the credentials label placed in the manual that came with Prism.

Prism configuration

The first page of the Guided Configuration contains the operating parameters of Prism.

Type of installation

The first information to be provided is the type of installation, which can be:

  • Single Prism
    • For installation of only one Prism on the system.
  • Main prism (cluster)
  • Secondary prism (cluster)
    • Use these options for installation of multiple Prisms on the same system.
The configurations for Single Prism will be given below. For the configuration of a Prism Cluster, follow the Cluster Guide.

Electrical system system: number of phases

Select type of plant on which the Prism is installed, which can be:

  • Single-phase
  • Two-phase*
  • Three-phase
* For two-phase systems, it may be necessary to install a transformer upstream of the Prism power line, as not all cars can charge on a two-phase system. Ask the dealer about it and give it a test charge.

Circuit breaker calibration

Select the corresponding value in amperes (A) of the size of the circuit breaker protecting the Prism power line:

Meter power

Enter the value in watts (W) corresponding to the contracted power supplied by the household meter:

Example: if the meter is 3kW, enter “3000” as the value.

Sensor downstream of the meter

Select YES if the Prism sensor, which is essential for managing load balancing, has been installed:

  1. Select the type of sensor installed by choosing from 100A (standard) or 1000A (for large-cut systems, which can be ordered from our shop as an optional accessory).
  2. After verifying that the value read by the sensor matches what is delivered by the meter, check “Yes, I have verified and the two values match.”

MID sensor presence

Set the drop-down menu to YES if a compatible MID sensor has been connected to Prism (optional, see this FAQ about this):

Check the next item if you want Prism to continue to receive data via its internal sensor if the MID fails.

Powerwall storage device presence

Select YES if you want to enable API communication with a Tesla Powerwall. Enter the required values in the fields:

  • IP address of the Powerwall.
  • Powerwall login email.
  • Tesla Gateway Password
This functionality may be discontinued if updates are applied by the Tesla manufacturer.

Load balancing

Set the drop-down menu to YES if you want to enable load balancing. Values should then be selected via the respective drop-down menus:

  • Data source:
    • Sensor installed
    • Powerwall
  • Presence of photovoltaic system: NO/YES.
  • Arera Experimentation: NO/YES
ARERA experimentation gives 5.5kW + 10% tolerance to reach 6kW. The sensor detects the current flow at the point of contact, but if the potential difference (voltage) in the cables is lower in Prism than that measured at the meter there can be power detection differences of a few hundred watts which then, by setting 6000 with ARERA, can cause the meter to disconnect. Always set the value to 5500 for safety.

Autostart

Select the charging start mode:

  • Automatic charging startup is allowed
  • No. Allow only thumb drives and Silla cards Requires the swipe of an RFID card provided by Silla
  • No. Also allow the use of generic cards Allows authorization with any RFID card with mifare protocol

Remote access

Enable remote access in order to use Prism through the MySilla application.

Communication via OCPP

In this section you can enter parameters to connect Prism to a Central System OCPP. Follow the dedicated guide for all the details:

Automatic Updates

Select whether you want Prism to update automatically(Yes) or through manual authorization(No)

Press Next and proceed to the next screen of the Configuration Wizard.

Network configuration

This page shows all the parameters of the network configuration.

Configurations for “Single Prism” mode installations are given. for Cluster installations follow the dedicated Cluster guide.

Current local network settings

Connecting to a WiFi network

Press on the WiFi network to which Prism is to be connected, enter the password, and press Connect:

Remote access testing

In this part, it is possible to check the connection status of Prism and communication with Silla servers for using cloud services such as MySilla and receiving updates:

Press on “Save and Close” to finish the configuration.
