Victron SmartSolar MPPT 150/70-Tr

Victron Energy SmartSolar MPPT 150/70-Tr is a high-efficiency solar charge controller with Maximum Power Point Tracking (MPPT), designed for photovoltaic systems with 12 V, 24 V, 36 V or 48 V battery banks. It converts available solar energy efficiently and provides a charging current of up to 70 A.

Fast MPPT tracking improves energy yield when sunlight changes or the array is partially shaded. Built-in Bluetooth enables configuration, monitoring and firmware updates through VictronConnect without requiring an additional communication module.

Key benefits

• Maximum PV input: 150 V DC; operating and start-up limit: up to 145 V.

• Nominal PV power up to 1000 W at 12 V, 2000 W at 24 V, 3000 W at 36 V and 4000 W at 48 V.
• Peak efficiency of up to 98%.
• Ultra-fast MPPT tracking for improved yield in changing solar conditions.
• Multi-stage adaptive charging algorithm with eight pre-programmed profiles or a user-defined algorithm.
• Suitable for lead-acid and lithium battery systems when the correct charging profile is configured.
• Built-in Bluetooth and a VE.Direct communication port.
• Remote on/off through a two-pole terminal.
• Parallel operation with other controllers is supported, without synchronisation between units.
• Programmable relay for external load control or signalling.
• Protection against PV reverse polarity, output short circuit and overheating.

Applications

Victron Energy SmartSolar MPPT 150/70-Tr is suitable for off-grid and hybrid photovoltaic systems in campervans, caravans, boats and professional vehicles, as well as stationary off-grid installations. Its high charging current makes it suitable for larger battery banks and PV arrays up to the nominal power limits specified for each system voltage.
