I give it 4.5 out of 5 stars.
I've been using the Victron Blue Smart IP22 12V 30A with three charging outputs for a while now and am very satisfied overall.
Installation and electrical connection were quick and easy. Connecting via Bluetooth to the VictronConnect app also worked flawlessly and was set up within minutes. The app is user-friendly and provides a good overview of the charging status and the charger's settings.
The charging performance is excellent, and the device operates reliably and with the high quality you'd expect from Victron.
The only drawback is monitoring multiple batteries. Although the charger has three charging outputs, the individual batteries cannot be monitored separately in the app. Only the overall charge status is displayed, as all outputs use the same charging algorithm. If you want to monitor the status of each battery individually, you'll need additional accessories, such as a SmartShunt or a battery monitor.
In conclusion, this is a high-quality, powerful charger with easy installation, reliable operation, and a very good Bluetooth app. Users who want to monitor multiple batteries individually should factor in the additional effort required for separate monitoring. I give it 4.5 out of 5 stars; only 5 are possible here.
