Ce que couvre cette vidéo
To aggregate solar charging data from multiple Victron charge controllers on a Raspberry Pi, users must modify the SignalK plugin configuration and create a custom flow in Node-RED. The standard VE.Direct to SignalK plugin defaults to displaying individual controller data rather than a combined total, which causes data overwriting when multiple solar arrays are connected.2:00 By renaming the paths for each controller in the plugin settings to distinct identifiers—such as "panel 1" and "panel 2"—the system can track individual inputs.3:14 A custom Node-RED flow then imports these separate current values, calculates their sum, and writes the total to a new SignalK variable named "ALLPANELCURRENT."6:40 This aggregated value can be visualized in the Virtuino 6 viewer app, which remains compatible with previous project files after updating to the latest version.9:00 This configuration ensures accurate monitoring of total solar power entering the battery bank, distinguishing between raw solar production and the net current actually charging the batteries.
