The Victron SmartSolar MPPT 150/70 is an ultrafast 70 A MPPT solar charge controller with built-in Bluetooth for live monitoring and advanced battery management.

• Ultrafast MPPT Technology: 70 A MPPT designed to deliver the highest possible energy yield in the shortest time.
• Max solar panel power: 1000W (12 V) / 2000W (24 V) / 3000W (36 V) / 4000W (48 V) — Max solar panel voltage: 150 V.
• Suitable for 12/24/36/48 V battery systems and compatible with a wide range of battery chemistries, including multiple lead‑acid and lithium charging stages.
• Built-in safety protection: PV short circuit, reverse polarity, overvoltage, overcurrent, reverse current protection, battery overvoltage and overheating protection (internal temperature sensor).
• Status LED indicators for quick system condition checks.
• Built-in Bluetooth: Connect to a phone or tablet using the VictronConnect app for configuration and monitoring.
• Live data transmission: Real‑time information including solar panel output, battery voltage, current and battery state of charge. Detailed data logs: system activity for the past 30 days available to view. Note: viewing full SOC history or advanced battery metrics may require a compatible Victron monitor or BMS.
• User‑defined battery charging algorithm: Option to disable preset values in favour of personalised charging parameters for each charging stage.
