Generator Auto-Start Setup with Victron — Is It Complicated?

Understanding the Victron Multiplus Configuration

Setting up a generator auto-start with Victron involves configuring the Multiplus inverter/charger to monitor the battery state and start the generator when necessary. The first step is to ensure that your Multiplus is configured to work with the generator, which typically involves setting the “AC Charge” and “AC Input” settings. For example, if you have a 12V battery bank and a 230V generator, you’ll need to set the Multiplus to accept 230V AC input and charge your battery accordingly.

Wiring the AC Output Connections

To connect your generator to the Victron system, you’ll need to wire the AC output of the generator to the AC input of the Multiplus. The typical wiring involves connecting the 230V AC output of the generator to the 230V AC input of the Multiplus, using suitable AC connectors and wiring. Make sure to follow the Victron wiring diagram and use the correct gauge wiring to prevent overheating or electrical shock.

Configuring the Generator Auto-Start

To configure the generator auto-start, you’ll need to use the Victron remote monitoring system (VRM) or the Victron GX device. The VRM or GX device allows you to monitor the battery state and configure the generator auto-start settings. Typically, you’ll need to set the “Generator Start” and “Generator Stop” settings, which allow you to specify the voltage level at which the generator should start and stop. For example, you might set the generator to start when the battery voltage drops below 12.2V and stop when it reaches 12.5V. By following these steps, you can ensure a smooth generator auto-start with your Victron system.
