Solar Charge Controller | Victron | SmartSolar MPPT 250/70 MC4
Product Details
The Victron SmartSolar MPPT 250/70 MC4 delivers identical electrical performance to the 250/70 TR — 70A output, 250V PV input, 12/24/48V compatibility, 99% efficiency — but uses MC4 panel connectors for the PV input. This makes it the preferred version wherever panels ship with MC4 leads and a direct cable-to-controller connection is desired. Synchronised parallel operation via Bluetooth, a programmable relay, and full VictronConnect wireless monitoring complete the specification.
Key Features
- Ultra-fast MPPT tracking
- Built-in Bluetooth Smart
- VE.Can and VE.Direct ports
- Programmable relay
- Remote on/off
- Synchronized parallel operation (up to 25 units via VE.Can)
- Eight pre-programmed charge algorithms + user defined

Use Cases
Large touring setups where the solar installer wants to run MC4 cable directly from rooftop panels to the controller — without junction boxes or terminal adapters — will find the MC4 version the cleaner choice.
Custom builds using aftermarket MC4-terminated flexible panels can wire directly to the 250/70 MC4 with no additional hardware. The 70A output fully utilises a 3kW panel array at 48V system voltage.
Offshore yachts and large powerboats where MC4 is the preferred panel connector for watertight deck penetrations benefit from this version. The high-efficiency MPPT ensures maximum harvest from expensive marine solar panels.
Off-grid homes using standard residential modules (which ship with MC4 leads) can connect directly to the 250/70 MC4 without wiring adapters. Pair with a Cerbo GX for remote monitoring via VRM.
App Control & Connectivity
All SmartSolar MPPT controllers feature built-in Bluetooth for wireless monitoring and configuration via the free VictronConnect app (iOS and Android). Adjust charge settings, view real-time solar data, and receive alerts — all without needing a laptop or additional hardware. For advanced monitoring, connect to a Victron GX device (Cerbo GX, Venus GX) for full system integration and remote access via VRM.
