Victron SmartSolar MPPT 250/70-Tr Solar Charge Controller | SCC125070221

The Victron SmartSolar MPPT 250/70-Tr is a solar charge controller built for off-grid and hybrid solar systems that need reliable battery charging with remote monitoring. It accepts a maximum PV open-circuit voltage of 250V and delivers up to 70A of charge current, with built-in Bluetooth for setup and monitoring through the VictronConnect app.

Victron SmartSolar MPPT 250/70-Tr key features

• PV input, maximum open-circuit voltage of 250V, allowing longer series-connected panel strings.
• Charge current, 70A maximum, suited to larger battery banks across 12V, 24V and 48V systems.
• Bluetooth built in, configure and monitor directly via VictronConnect on iOS and Android, no dongle required.
• MPPT tracking, a true MPPT algorithm tracks rapidly across changing irradiance.
• TR terminals, screw terminal connections on both PV and battery sides for fixed wiring.
• Battery chemistries, supports lithium-ion (LiFePO4), AGM, gel and flooded types with configurable charge profiles.
• GX integration, VE.Direct port for connection to a Victron GX device and the VRM portal.
• Load output, integrated, programmable DC load output.

Applications

Suited to off-grid cabins and rural properties on 12V, 24V or 48V battery systems, commercial off-grid installs needing high PV input voltage, and marine or vehicle setups where a high-voltage array charges a 12V or 24V service bank. It also fits hybrid systems using a Victron GX device with VRM monitoring, backup power installations with lithium or lead-acid banks, and agricultural or telecoms sites needing remote monitoring.

Monitoring and configuration

VictronConnect lets installers set charge parameters, check live data, review yield history and run a battery equalisation cycle from a phone or tablet. Connecting to a GX device such as a Cerbo GX adds full VRM integration, though the controller works standalone without one.

Battery charging

A dedicated LiFePO4 profile is available for lithium batteries, and the controller can respond to a BMS signal to stop charging when needed. The Tr terminal type uses screw connections, standard for permanent wiring in enclosures or distribution boards.
