If you’ve purchased a Victron SmartSolar MPPT charge controller, you can easily monitor and manage your solar system via Bluetooth using Victron’s VictronConnect app. This guide walks you through the connection process and what you can do once connected.

✅ What You Need

• A Victron SmartSolar MPPT controller (Bluetooth built-in)

• The VictronConnect app (Free for iOS and Android)

Download the VictronConnect App:

• Android (Google Play)

? Step-by-Step: Connecting to Bluetooth

1. Power On Your Victron MPPT

Ensure your MPPT is powered by either:

• A connected solar panel (during daylight), or

• A connected battery bank

⚠️ If there's no power input, the Bluetooth signal won’t be active.

2. Enable Bluetooth on Your Phone

Make sure Bluetooth is turned on in your phone or tablet's settings.

3. Open the VictronConnect App

Launch the app. It will begin scanning for nearby Victron devices automatically.
