Victron SmartSolar MPPT 250/70-MC4 VE.Can

Victron Energy SmartSolar MPPT 250/70-MC4 VE.Can – solar charge controller

An intelligent MPPT solar charge controller for efficiently charging 12 V, 24 V, 36 V or 48 V battery systems from photovoltaic arrays with a maximum voltage of up to 250 V. Its fast Maximum Power Point Tracking technology extracts as much available energy as possible from the solar array and converts it into an optimized charging current for the battery bank.

This model features MC4 photovoltaic connectors, built-in Bluetooth, and VE.Can and VE.Direct communication. It supports synchronized parallel operation of multiple controllers, remote on/off control, a programmable relay, and integration with Victron GX devices for system monitoring and management.

Key benefits

• Maximum charge current of up to 70 A.
• Suitable for 12 V, 24 V, 36 V and 48 V battery systems; 12/24/48 V are selected automatically, while 36 V is selected manually.
