Instalación de Conexión a Red Huawei 16.500Wh/día, con paneles solares

Installation of Huawei Solar Power System

This video showcases the installation process of a Huawei solar power system for grid connection and self-consumption. The system consists of 10 PowerEn high-efficiency solar panels with a total capacity of approximately 16,500 watts. The main components include a 3000-watt Huawei single-phase inverter and a Carlo Gavazzi energy meter for monitoring.

Panel Installation

  • The solar panels are mounted on the roof using the Cachete 915 tile roof mounting structure.
  • Two rows of panels are installed to optimize space.
  • Safety measures are taken during panel installation due to their size and weight.

Connection and Wiring

  • The positive and negative terminals of each panel are connected in series to form a string.
  • A waterproof junction box is installed to protect the wiring connections.
  • Corrugated tubing is used to route the cables from the panels to the junction box and into the house.
  • A DC protection box is installed inside the house to house fuses for panel-level protection.

Inverter Installation

  • The Huawei SUN2000KTL 3000W single-phase inverter is used in this installation.
  • A wall-mounted bracket is used to securely mount the inverter on the wall.
  • Proper measurements, leveling, and drilling are done before attaching the bracket.
  • The inverter is then attached to the bracket using screws provided with it.

System Functionality

  • The Huawei inverter operates as a traditional grid-tied inverter but can also be combined with LG high-voltage batteries for hybrid functionality.
  • It offers an efficiency rating of 98% for optimal performance.

Connecting Panels and Inverter

This section focuses on connecting the solar panels in series and linking them to the Huawei inverter.

Series Connection of Panels

  • The positive terminal of one panel is connected to the negative terminal of the next panel until all panels are connected.
  • This series connection ensures a higher voltage for efficient operation.
  • The identical orientation of all panels enhances performance.

Wiring and Protection

  • The cables from the panels are routed through corrugated tubing into the house.
  • A DC protection box is installed inside the house to house fuses for panel-level protection.

Installation of Huawei Inverter

This section focuses on installing and mounting the Huawei inverter.

Mounting the Inverter

  • The wall-mounted bracket included with the inverter is used for installation.
  • Measurements, leveling, drilling, and securing with screws are done to mount the bracket securely on the wall.
  • The inverter is then attached to the bracket using screws provided with it.

System Features

  • The Huawei SUN2000KTL 3000W single-phase inverter offers high efficiency and can be used as a grid-tied or hybrid system with LG high-voltage batteries.

Preparing the Data Cable

In this section, the process of preparing the data cable is explained.

Preparing the Cable

  • Enroll some extra wiring in case it is needed in the future.
  • Strip and connect the orange and green wires to the corresponding terminals on the inverter.
  • The color code should be respected to ensure proper connection between the inverter and bat and meter.

Connecting Data Cable to Electrical Panel

This section focuses on connecting the data cable to the electrical panel.

Incorporating Bat and Meter into Electrical Panel

  • Work with caution without any power supply for safety.
  • Disconnect the general output to insert bat and meter between it and the distribution board.
  • Connect a cable from bat and meter output to the distribution board using crimped wiring with ferrules.
  • Connect the general circuit breaker to bat and meter using its four ports (1 & 2 for input/output).
  • Connect neutral and phase wires from general circuit breaker output to complete wiring from circuit breaker to bat and meter, then to distribution board.

Connecting Inverter Wiring

This section explains how to connect inverter wiring.

Intermediary Devices

  • Install a differential switch and another circuit breaker as intermediaries between the inverter and distribution board.
  • Connect these devices together using a quick connection plug.

Inverter Wiring Connection

  • Connect black and blue cables from inverter (carrying energy generated by panels) to intermediaries (differential switch & circuit breaker).
  • Connect earth wire of inverter to corresponding terminal on electrical panel.
  • Connect data cable from inverter to added protections.

Summary of Connections Made So Far

This section summarizes all connections made up until now.

Recap of Connections

  • Bat and meter installed to measure energy consumption in the entire electrical panel.
  • Inverter wiring connected to added differential switch and circuit breaker, then to distribution board.
  • Positive and negative cables from panels connected to corresponding terminals on the inverter.

Configuring the Inverter

This section explains how to configure the inverter.

Accessing the Inverter Application

  • Use the "Fusión Solar" application for Huawei inverters.
  • Scan the QR code on the inverter and enter username and password to connect to its Wi-Fi network.

Configuration Steps

  • Set country as Spain with voltage of 230V and frequency of 50Hz.
  • Select powermeter option that matches the model of bat and meter installed in the electrical panel.
  • Connect to home router by entering account details.
  • Create a new plant for photovoltaic system by providing necessary information (name, capacity, location, etc.).
  • Once configured, monitor system production through the application.

Conclusion

This section concludes the installation process.

Benefits of Solar System

  • The solar system allows for significant self-consumption during daylight hours, reducing electricity costs.
  • Monitoring consumption patterns can help determine if adding a high-voltage LG battery would further increase self-consumption and reduce electric bills.

Video description

En este vídeo de AutoSolar les mostramos un sistema de conexión a red con un Kit solar para autoconsumo con #InversorHuawei Este kit es capaz de ofrecer una media de unos 16.500Wh/día porque está compuesto por 10 paneles solares de 330W. Además este modelo de inversor monofásico de 3000W de la marca Huawei, y un vatímetro Carlo Gavazzi compatible para medir el requerimiento de energía de nuestra instalación. Nuestro equipo de instaladores solares de Autosolar se ha desplazado a una localidad cercana a nuestras instalaciones para montarle a nuestro cliente en su vivienda permanente este kit solar de conexión a red. Recordamos que este tipo de sistemas nos permiten disfrutar de un gran ahorro sobre los consumos que tengamos en horas de sol, ya que la energía generada por los paneles se consume de forma instantánea cuando se genera, por lo que recomendamos aprovechar al máximo la franja del día en el que la energía nos sale gratis. Con este kit solar de conexión a red para una vivienda habitual, nuestro cliente puede alimentar gran parte de los consumos en horas de sol y reducir el gasto de luz durante el día.
