SIM card/LTE
The charger can be connected to the internet via a SIM card and LTE connection by simply installing the SIM card into the charger.
For detailed instructions, specifications, and requirements for the LTE connection, please refer to the latest version of the Peblar user and installation manual (Section 2.2).
LTE
If LTE network connection is used, insert a SIM card. Note: the SIM card may already be installed upon delivery.

(W)LAN
The charger can be connected to a network and the internet via Wi-Fi or a LAN (Ethernet) connection. For optimal connection and network stability, it is always recommended to connect the charger via Ethernet. This is especially important for stable and reliable load balancing, such as when using for example a Homewizard P1 dongle.
For detailed instructions, specifications, and requirements for a (W)LAN connection, please refer to the latest version of the Peblar user and installation manual (section 2.5).
Router needs to offer 2.4 GHz networks with WPA2 security, and the b and a/g protocol.
5 GHz, unprotected, and different protocol networks do not work.
Network interface priority
When connecting to the internet, the charger follows a defined priority:
- LTE / Cellular / SIM
- Ethernet / UTP / LAN
- WLAN / WiFi / Wi-Fi
This can potentially result in increased data consumption on the LTE interface. If the charger connects firstly to the internet via e.g. ethernet, while also having a SIM installed, the charger will stick to the ethernet interface, even though the LTE has priority over the ethernet connection.
Network stability
Network stability is important for EV chargers as they often rely on constant communication with various systems to function efficiently. Chargers are typically connected to a back office for effectively prevent circuit overloads and automated billing.
The network stability is also related to the signal strength of the network. It is advised to measure the signal strength at the desired location of the charger. A minimum of -70 dBm (Decibel-Milliwatts) is required for the charger to be connected to a local network via Wi-Fi.
It is not advised to connect the charger directly to the router via WiFi if the measured signal strength is below -65 dBm (e.g. a score of -85 would be insufficient).
