The Victron SmartSolar MPPT 150/60-MC4 is a solar charge controller built for off-grid and battery-based solar systems. It handles a maximum PV open-circuit voltage of 150V and delivers up to 60A of charge current, with MC4 connectors built into the unit for direct panel connection.

Key features of the SmartSolar MPPT 150/60-MC4

• Maximum PV open-circuit voltage, 150V, suited to higher-voltage panel strings.
• Maximum charge current, 60A output for medium to large battery banks.
• MC4 connectors, integrated, for direct connection to panel cables without extra adaptors.
• Bluetooth, built in, works with the VictronConnect app for monitoring, configuration and firmware updates.
• Charging algorithm, multi-stage adaptive charging supports AGM, gel, flooded and lithium batteries.
• Networking, VE.Direct and VE.Smart Networking allow synchronised charging across multiple units.

Product overview

The 150V maximum input voltage suits longer panel strings, which is useful where strings are run at higher voltage to cut cable losses over distance. The 60A output covers medium to large off-grid battery banks.

Built-in Bluetooth removes the need for a separate dongle. Through the VictronConnect app on iOS or Android, installers can set charge parameters, check real-time data and update firmware without opening the unit up. VE.Smart Networking lets the controller take battery temperature and voltage data from compatible Victron sensors, improving charge accuracy without extra wiring.

The integrated MC4 connectors accept standard solar panel MC4 cables directly, cutting down on field-fitted connectors. Charge profiles can be adjusted in the app for non-standard battery types.

Applications

• Off-grid residential systems with medium to large battery banks.
• Commercial off-grid installations needing higher PV string voltages.
• Marine and narrowboat solar systems, where direct MC4 connection simplifies wiring.
• Motorhomes and expedition vehicles carrying larger panel arrays.
• Telecoms and remote monitoring sites needing unattended battery charging.

Installation notes

Fit this by a qualified electrician or accredited solar installer. String design needs to keep open-circuit voltage under the 150V limit even in cold weather, when panel voltage rises. Battery connections must be fused and sized to match the 60A charge current. Follow Victron's published wiring guidance for VE.Direct and VE.Smart Networking connections.
