Peblar (Open Bèta)

Modbus TCP server

This document contains the specification of the Peblar Modbus TCP server. This server provides an interface to retrieve information from the system and provides control over the charge current.

The Modbus TCP server is supported by Peblar products from firmware versions 1.6 and onwards.

Before the API can be accessed, it is required to be enabled in the advanced settings page of the charger's web interface. It can be configure to either ReadOnly or ReadWrite mode: The first mode only only retrieval of information while the latter also allows control over charge current and ability to force 1-phase charging.
