- Los SolaX G2 y SolaX G3 híbridos tienen Ethernet incorporado (el Qcells Q.VOLT HYB-G3-3P es un SolaX G4 a pesar de la nomenclatura G3).
- Los SolaX G4 y otros no tienen Ethernet incorporado, la comunicación es posible a través del puerto COM serie RS485.
- Solo SolaX - No todos los dongles SolaX proporcionan comunicación modbus, el PocketWiFi mínimo soportado es PocketWiFi 3.0 PocketLAN no proporciona una conexión Modbus.
- Adaptador RS485 a Ethernet - la mejor manera de conectarse a su inversor.
- Adaptador RS485 a USB - no recomendado, puede causar errores en HA.
- Dongle Solis - ver abajo
La interfaz RS485 utiliza solo el pin4 (cable azul) y el pin5 (blanco-azul). La polaridad es importante, así que asegúrate de que el pin4 (cable azul en cables típicos) esté conectado al lead A de tu adaptador y el pin5 (cable blanco-azul) al lead B de tu adaptador.
Los cables RS485 pueden ser bastante largos, por lo que 25 metros o más son posibles. Puedes usar el par azul de un cable cat5 o cat6 estándar.
Asegúrate de verificar la tasa de baudios de tu inversor con la Página Wiki y asegúrate de que coincida con la tasa de baudios del adaptador de Ethernet a RS485. Puedes confirmar la tasa de baudios en la pantalla LCD en la parte frontal de tu inversor, dentro de los Menús.
La dirección Modbus por defecto es 1. Algunas personas han reportado que su dirección Modbus era 4.
Atención: Este trabajo se basa en la documentación del protocolo común para los dispositivos X1 y X3. La documentación no siempre queda clara sobre qué parámetros no se aplican al inversor X1, por lo que algunas de las entidades que aparecen pueden no tener un significado en X1. Puedes informar sobre esto y pueden ser eliminadas para X1.
Hay un puerto marcado como COM en el inversor G4, algunos manuales de usuario por error afirman que este es un puerto Ethernet.
¡NO CONECTE ESTE PUERTO COM A UN SWITCH DE ETHERNET - su puerto de switch Ethernet fallará si lo hace!!!
Adaptador Waveshare RS485 a ETH (B)
-
se conecta a través de Ethernet a su router/conmutador de red doméstico
-
use la herramienta "vircom" (Windows) para establecer la dirección IP que coincida con su lan (o para permitir que el dispositivo use DHCP, no usa DHCP por defecto, sin embargo recomendamos usar una IP estática)
-
configúrelo para usar "Modbus TCP a RTU", asegúrese de que el modo de trabajo sea "Servidor TCP" y el servidor escuche en el puerto 502. Asegúrese de que la tasa de baudios coincida con la tasa de baudios de su inversor (ver: configuraciones > configuraciones avanzadas > modbus > tasa de baudios)
-
En "Más configuraciones avanzadas...",
- SolaX establecer el tipo de puerta de enlace Modbus en "Modo simple Modbus a TCP/IP"
- Sofar Solar y posiblemente Growatt establecer el tipo de puerta de enlace Modbus en "Tipo de almacenamiento de consulta automática"
- todos los demás parámetros pueden dejarse por defecto
-
puede verificar la configuración abriendo la página web de su adaptador. Debería mostrar algo como:
-
En el improbable caso de que tenga varios inversores conectados a un adaptador RS485, es posible que deba modificar la bandera de múltiples anfitriones (no probado). El sistema aumentará el espacio entre los mensajes, lo que ralentizará el rendimiento de la comunicación. Asegúrese de que su intervalo de sondeo sea lo suficientemente largo (el LED de acción no debería encenderse todo el tiempo).
-
si todo está bien, el LED de PWR debería ser rojo, el LED de LINK debería ser inicialmente verde y volverse permanentemente azul tan pronto como HA haya establecido la conexión. El LED ACT debería estar apagado la mayor parte del tiempo, pero debería parpadear en verde (enviar) y azul (recibir) brevemente cada 15 segundos (el intervalo de sondeo por defecto). De la documentación de Waveshare:
- Si la luz de enlace no es verde, el cable de red no está conectado correctamente, por favor revise el cable de red.
- Si la luz de enlace no es azul (solo considere el modo de trabajo TCP), el software del computador principal no tiene un puerto serie. El servidor establece una conexión, considere si la dirección IP está configurada en el mismo segmento de red.
- Si la luz activa es verde, significa que el puerto de red está enviando datos, pero no hay un dispositivo serial devolviendo datos. Por favor revisa si la tasa de baudios está configurada correctamente y si los positivos y negativos de RS485 están conectados inversamente.
Al configurar la integración Modbus de SolaX, especifique la dirección IP de red del dispositivo Waveshare, no la dirección de SolaX. No marque la casilla de la bandera Serial RS485; el puerto serie se ignora en esta configuración.
Adaptador USB a RS485
- Conectado directamente por USB a su sistema HA
- Este modelo de bajo costo se puede encontrar en varias tiendas en línea, busque USB RS485
- Chipset CH340C (productos similares con chipset FTDI FT232 también deberían funcionar pero son más caros)
Al configurar la integración Modbus de SolaX, marque la bandera de 'puerto serie RS485' y especifique el nombre real del puerto serie (como se ve en la salida de 'ls /dev/ttyUSB*'). En caso de tener más de un dispositivo usb, tiene sentido usar el nombre visible en la salida de 'ls /dev/serial/by-id'. En esta configuración, la dirección IP y el puerto TCP no importan, use 'localhost' como dirección IP y deje el puerto TCP por defecto 502.
Múltiples inversores conectados a un adaptador RS485 & Resistores de terminación
Debería ser posible conectar múltiples inversores al mismo adaptador RS485 (por ejemplo, Waveshare). Los inversores deben tener direcciones Modbus diferentes, por lo que debe cambiar primero las direcciones Modbus de los inversores. Luego configure una instancia para cada inversor. El diálogo de configuración le permite establecer la dirección Modbus.
El uso de resistores de terminación es requerido al conectar múltiples inversores. Coloque un resistor de 120 Ohmios entre A y B en el adaptador RS485 y coloque un resistor de 120 Ohmios entre A y B en el último inversor conectado.
SolaX PocketWiFi 3.0
Esta interfaz requiere más pruebas y no se garantiza que funcione:
- Conecta el dongle a tu red Wi-Fi
- Actualiza el firmware a la última versión
- Configura la integración con la IP del dongle y otros ajustes por defecto.
