Three-phase Victron Quattro inverter system for stable home power supply

Review of the three-phase inverter system with three Victron Quattro 48/10000 inverters:

The three-phase inverter system designed to provide stable power to a private home, consisting of three Victron Quattro 48/10000 inverters (each with 10,000W capacity), is the ideal solution for ensuring uninterrupted operation of all the home’s electrical systems. The primary task of this system is to provide a stable power supply to heavy consumers such as air conditioners, lighting, household appliances, and also to back up the internet connection, even during a grid outage.

The key feature of this system is its capability to connect 16 battery units with a capacity of 12V 200Ah each. This allows the system to operate efficiently in off-grid mode with a power consumption of up to 1500W, significantly extending the autonomy. For example, at an average consumption of 1500W, the system can keep the house running for a long period without relying on the main grid.

Battery monitoring is carried out via the Victron BMV-700 battery monitor, which tracks the charge level and battery health in real-time. Additionally, the system is equipped with a Victron Color Control monitor, offering detailed control of all inverter and battery parameters. This monitor not only allows for real-time load monitoring but also enables remote management of the system via the internet.

To extend autonomy and reduce battery load during prolonged power outages, a diesel generator is connected to the system. The generator starts automatically when the batteries reach a certain discharge level, ensuring continuous power to all essential home systems.

The batteries are further protected by battery balancers that maintain all batteries in optimal condition, prolonging their lifespan and ensuring stable system operation over many years. This balancing system prevents overheating or overcharging of individual batteries, making the operation safe and durable.
