Victron SmartSolar MPPT 250/70-Tr Solar Charge Controller

The Victron SmartSolar MPPT 250/70-Tr accepts up to 250V from your solar array and delivers up to 70A of charge current to a 12V, 24V, 36V or 48V battery bank. The high input voltage lets you wire long series strings of full-size residential panels, which keeps PV wire runs thin and losses low — ideal for cabins, shops, larger RV and van builds, and off-grid homes.

Victron's ultra-fast MPPT tracking locks onto the true maximum power point even under partial shade, and the fanless design runs at up to 99% efficiency. Built-in Bluetooth lets you set up, monitor and update the controller from the VictronConnect app, and the VE.Direct port connects it to a Cerbo GX or other GX device for VRM remote monitoring.
