Solar Charge Controller | Victron | SmartSolar MPPT 250/70
Product Details
The Victron SmartSolar MPPT 250/70 combines the high 250V PV string voltage capability with a 70A output current for 12V, 24V, or 48V battery banks. At 48V it handles up to 4,000W of solar, with 99% peak conversion efficiency. Screw terminal PV connections, a programmable relay for external load or generator control, and synchronised parallel operation via Bluetooth make this a versatile choice for larger off-grid systems, commercial installations, and high-spec marine builds. VictronConnect provides full wireless monitoring and configuration.
Key Features
- Ultra-fast MPPT tracking
- Built-in Bluetooth Smart
- VE.Direct port
- Programmable relay
- Remote on/off
- Synchronized parallel operation (up to 10 units via Bluetooth)
- Eight pre-programmed charge algorithms + user defined

Compatible Battery Types
Works with AGM, Gel, Flooded (wet cell), LiFePO4, and lithium-ion batteries. Battery type and absorption/float voltages are configurable via the VictronConnect app.
Use Cases
Large motorhomes fitted with four 200W panels in series reach close to the 250V OCV ceiling — the 250/70 handles this comfortably while delivering fast charge rates to a 300Ah LiFePO4 bank.
Overlanders building custom 48V power systems with high-voltage solar strings benefit from the 250V rating and 70A output. Connect to a Cerbo GX and access full system data remotely via the VRM portal.
For commercial fishing vessels and charter boats with high daily energy consumption, the 250/70 pairs with a large panel array to deliver meaningful solar offset against fuel-powered generation.
A reliable workhorse in 4–6kW off-grid residential systems, typically paired with a MultiPlus-II inverter/charger and a 48V lithium battery bank for whole-house energy independence.
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.
