Product catalog summary

Introduction
The document addresses the issue of grid-connected solar systems shutting down during power outages. It highlights the dependency of standard configurations on the grid, which leads to total blackout despite having solar installations. The proposed solution involves adding an inverter/charger and batteries to maintain power supply during outages.

Problem Statement
Standard PV systems shut down during power outages, leaving buildings without power. This issue is common across various grid-connected renewable energy solutions.

Solution Overview
The solution involves using a Victron MultiPlus or Quattro inverter/charger with a SolarSwitch. This setup allows solar power to be redirected to the inverter's output during grid failures, balancing power between the load and solar inverter. Excess power charges the battery or is redirected to other loads.

System Configurations
1. **Two Meter System**: Utilizes MultiPlus and SolarSwitch to manage power distribution during grid availability and failures.
2. **One Meter System**: Suitable for systems with PV back feed into the grid, using batteries to store excess energy.
3. **Genset Backup**: Quattro inverter is recommended for systems with generator backup, allowing automatic switching between grid and generator.

Operating Modes
A. Grid Present: All loads are powered by the grid, and solar power is fed into the grid.
B. Grid Failure: Solar energy powers protected loads and recharges batteries.
C. Batteries Discharged: Loads are disconnected, and solar energy recharges the battery.

Important Features
MultiPlus and Quattro inverters are ready for use post-installation, with easy configuration via DIP switches or VE.Net/Blue Power panels. They include an integrated battery monitor for managing generator or grid connections.

Specifications
The SolarSwitch supports input voltages of 187-265 VAC and frequencies of 45-65 Hz, with a maximum switch-through current of 25A. It includes three programmable relays for various applications like alarms and load shedding.

Standards and Compliance
The system complies with safety standards EN 60335-1 and EN 60335-2-29, and emission/immunity standards EN55014-1, EN 55014-2, and EN 61000-3-3.

Conclusion
The document provides a comprehensive solution for maintaining power supply during grid outages using Victron's MultiPlus or Quattro inverters and SolarSwitch, ensuring efficient use of solar energy and backup power sources.

VE SolarSwitch No-break back-up for grid connected solar systems Introduction: preventing shut down of the PV system in the event of a power outage A rapidly growing number of houses, farms and other buildings are being fitted with grid connected solar installations. The standard configuration has an important drawback: it is dependent on the grid. If the grid fails, the grid connected inverter shuts down and a total blackout is the result, despite the investment in a solar installation. The same is true for other grid connected alternative energy solutions, such as wind, water or micro CHP (micro...

The solution a Victron MultiPlus or Quattro inverter/charger with SolarSwitch Figure 3: Two meter system with MultiPlus and SolarSwitch When the public grid is available, the Victron SolarSwitch will connect the solar inverter directly to the grid. If the grid fails, the power from the solar inverter will be redirected to the output of the MultiPlus. The MultiPlus replaces the grid and will balance the power mismatch between the load and the solar inverter. A power shortage will be supplemented by the MultiPlus, discharging the battery, and excess power will be used to recharge the battery. Once...

Important features After installation, the MultiPlus or Quattro is ready for use. If settings have to be changed, this can be done in a matter of minutes with a new DIP switch setting procedure. Even parallel and 3-phase operation can be programmed with DIP switches: no computer needed! Alternatively, a VE.Net or Blue Power panel can be used instead of the DIP switches. Sophisticated software (VE.Bus Quick Configure and VE.Bus System Configurator) is available to configure several new, advanced, features. Integrated Battery Monitor At request all Multi’s and Quattro’s can be fitted with an integrated...
