cFos Power Brain Configuration

EVSE enable

Generally switches loading on and off.

Default settings at startup

Determines which values are selected after start-up in the absence of a charge manager.

DC Sensor

You should always leave the DC sensor / residual current sensor switched active, unless you are operating the cFos Power Brain 11kW on a type B residual current circuit breaker. Without a residual current circuit breaker, operation without a DC sensor is not permitted!

EVSE as OCPP Client

Here you activate and configure the OCPP client of the cFos Power Brain. The OCPP client allows the cFos Power Brains to operate on an OCPP-enabled backend for the following purposes:

• Monitoring and displaying the status of the wallbox
• Load management by an external backend
• Billing of charging processes by an OCPP-enabled billing service

EVSE as Modbus

You can also allow remote control of the cFos Power Brain 11kW wallbox via Modbus.

S0 Meter 1 and 2

You can connect an S0 meter to the two S0 inputs of the cFos Power Brain. This is then available as a Modbus device. As with "Modbus EVSE", you can define for the counters to which slave ID the counter(s) listen and which TCP port or COM port settings apply.

An S0 meter sends a certain number of pulses per measured kWh. You set this under "Pulses/kWh". The cFos Power Brain can also simulate current and voltage values if certain readout software requires this. You can set the phase voltage and specify the phases to which the pulses refer.

Modbus TCP/RTU Proxy

The cFos Power Brain 11kW Wallbox speaks TCP/IP by default and has a built-in RS 485 interface. It makes sense to map Modbus TCP to Modbus RTU (RS 485). This allows you to access devices connected to the RS 485 interface via WLAN and Modbus TCP.

Wifi Access Point

You can also use the cFos Power Brain 11kW Walbox as a WLAN access point. Please do not expect great transmission rates. However, you can use it to establish a WLAN connection to your car or other wallboxes.

The name of the base station, the WLAN password and the channel can be set.

WiFi Station

Here you can and should log your cFos Power Brain 11kW Wallbox into your home network, e.g. into your WLAN-enabled Internet router. To do this, select the appropriate name of the base station and the WLAN password. You can also set the host name with which the Power Brain registers with DHCP (and is therefore visible in the home network), as well as a DNS server. Since the cFos Power Brain 11kW Wallbox does not have its own clock, you should set a time server to synchronise the time.

With "Internet Hotspot" you activate the forwarding of IP packets from the WLAN access point to your Internet router, i.e. you make the WLAN hotspot Internet-capable.

Time

Here you can set the time of the cFos Power Brain. Pay attention to the correct time zone. In Germany this is UTC+1 Western Europe.

Firmware update

Here you can check for new versions and download a firmware update. Only if the downloaded firmware contains the correct signature, it will be installed.
