Havells Solar ============= .. seo:: :description: Instructions for setting up Havells inverter reading on modbus. :image: havellsgti5000d_s.jpg :keywords: Havells Enviro, Havells GTI The ``Havells Inverter`` sensor platform allows you to use Havells inverter data reading on modbus (`website `__) with ESPHome. .. figure:: images/havellsgti5000d.jpg :align: center :width: 50.0% Havells On Grid Solar Inverter. The communication with this component is done via a :ref:`UART ` using :ref:`Modbus `. You must therefore have a ``uart:`` and ``modbus:`` entry in your configuration with both the TX and RX pins set to some pins on your board and the baud rate set to 9600. .. code-block:: yaml # Example configuration entry sensor: - platform: havells_solar update_interval: 60s phase_a: voltage: name: "HAVELLS Phase A Voltage" current: name: "HAVELLS Phase A Current" phase_b: voltage: name: "HAVELLS Voltage Phase B" current: name: "HAVELLS Current Phase B" phase_c: voltage: name: "HAVELLS Voltage Phase C" current: name: "HAVELLS Current Phase C" pv1: voltage: name: "HAVELLS PV1 Voltage" current: name: "HAVELLS PV1 Current" active_power: name: "HAVELLS PV1 Active Power" voltage_sampled_by_secondary_cpu: name: "HAVELLS PV1 Voltage Sampled By Slave CPU" insulation_of_p_to_ground: name: "HAVELLS PV1 Insulation Of +VE To Ground" pv2: voltage: name: "HAVELLS PV2 Voltage" current: name: "HAVELLS PV2 Current" active_power: name: "HAVELLS PV2 Active Power" voltage_sampled_by_secondary_cpu: name: "HAVELLS PV2 Voltage Sampled By Slave CPU" insulation_of_p_to_ground: name: "HAVELLS PV2 Insulation Of +VE To Ground" active_power: name: "HAVELLS Active Power" reactive_power: name: "HAVELLS Reactive Power" frequency: name: "HAVELLS Frequency" energy_production_day: name: "HAVELLS Today's Generation" total_energy_production: name: "HAVELLS Total Energy Production" total_generation_time: name: "HAVELLS Total Generation Time" today_generation_time: name: "HAVELLS Today Generation Time" inverter_module_temp: name: "HAVELLS Inverter Module Temp" inverter_inner_temp: name: "HAVELLS Inverter Inner Temp" inverter_bus_voltage: name: "HAVELLS Inverter BUS Voltage" insulation_of_pv_n_to_ground: name: "HAVELLS Insulation Of PV- To Ground" gfci_value: name: "HAVELLS GFCI Value" dci_of_r: name: "HAVELLS DCI Of R" dci_of_s: name: "HAVELLS DCI Of S" dci_of_t: name: "HAVELLS DCI Of T" Configuration variables: ------------------------ - **phase_a** (*Optional*): The group of exposed sensors for Phase A/1. - **current** (*Optional*): Use the current value of the sensor in amperes.
