Victron Off Grid build Australia.

Summary

In this video, the creator documents the installation of an off-grid Victron solar system in a remote location north of Perth. After preparing the system in the workshop, they arrive on-site to install and commission it, showcasing the setup of solar panels, inverters, and batteries. The system is designed for future expansion, including the addition of more batteries and solar panels. The video highlights the challenges of working off-grid, the use of a generator as a backup, and the importance of compliance with Australian regulations. The creator also explains system components like the transfer switch, modem for remote monitoring, and the labeling requirements for safety and regulations.

Takeaways

• 😀 The installer is setting up an off-grid solar system in a winery north of Perth using a Victron system.
• 😀 The installer builds the system in their workshop first, then transports it to the site for quicker and more efficient installation.
• 😀 The current setup uses 11 solar panels, with plans to add more in the future to accommodate the full system capacity.
• 😀 The system is designed to support temporary living accommodations while the main house is under construction.
• 😀 The off-grid system uses two batteries, with space in the cabinet for up to eight batteries in the future.
• 😀 The system includes a transfer switch that allows the user to switch to a generator if the solar system fails, ensuring continuous power.
• 😀 A Victron Quattro inverter, though larger than needed, is used because it was the only stock available at the time.
• 😀 The system has a remote monitoring feature via a modem connected to the Servo GX device, which allows for system management and troubleshooting from anywhere.
• 😀 Strict labeling and safety regulations are followed in Australia, including detailed system plans and emergency contact information.
• 😀 A subsidy on solar panels is available in Australia, but it requires installers to be accredited and physically present for the installation, with penalties for fraud.

Q & A

What type of off-grid system is being installed in the video?

The video describes the installation of a Victron off-grid system, which includes a charge controller, inverter, batteries, and a communication device for remote monitoring.

Why does the installer build the system in the workshop before bringing it to site?

The installer builds the system in the workshop to save time on-site, take advantage of good Wi-Fi for commissioning, and ensure everything is set up properly before installation.

What is the capacity of the solar system's battery setup, and how is it designed for future expansion?

The current system uses two batteries, but the cabinet is sized to accommodate up to eight batteries. This allows for future expansion, with additional batteries and solar panels to be added as needed.

What is the purpose of the 4G modem in the Victron system?

The 4G modem connects to the Servo GX device to allow remote monitoring and configuration of the system. This provides the ability to check the system's performance and make changes if necessary.

How does the Victron Quattro inverter differ from other models like the MultiPlus?

The Quattro inverter has two AC inputs, while the MultiPlus has just one. In this case, the Quattro was chosen because it was the available stock, although a MultiPlus would have been sufficient for the setup.

Why is a transfer switch included in the system, and how does it work?

The transfer switch allows the user to switch to a generator if the system fails. It provides a backup power source and ensures that the system remains operational until the issue is resolved.

What are the labeling requirements for solar installations in Australia?

In Australia, solar installations must adhere to strict labeling requirements, including material safety data sheets, shutdown procedures, and the international number for the type of battery installed. This ensures safety and compliance with regulations.

How is the battery cabinet designed for ease of maintenance?

The battery cabinet is designed with removable sides, back, and front, making it easier for installers to work on the system. The front door is a glass door with pins for easy removal.

What challenges does the installer face when mounting the heavy inverter?

The installer struggles to lift and position the heavy inverter by himself. He uses a ladder and careful techniques to move it into place, dealing with the challenge of getting the cables into their proper slots while managing the weight of the unit.

What are the implications of the labeling regulations for solar installers in terms of subsidies?

In Australia, subsidies for solar installations are significant, and strict regulations, including proof of the installer’s presence on-site, ensure that only qualified professionals complete the work. This helps prevent fraudulent claims and ensures safety standards are met.
