Solar Charge Controller | Victron | SmartSolar MPPT 250/85 MC4
Product Details
The Victron SmartSolar MPPT 250/85 MC4 matches the full specification of the 250/85 TR — 85A output, 250V PV input, VE.Can bus, 12/24/48V compatibility, 99% efficiency — while substituting MC4 connectors for the PV input terminals. For installers working with panel arrays that terminate in MC4 leads, this version eliminates the need for junction boxes or wiring adapters. VE.Can allows up to 25 units to operate in synchronised parallel, with full system visibility through a Cerbo GX and the Victron VRM portal.

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
Premium caravan and motorhome builds using high-voltage MC4 panel strings can connect directly to this controller. The 85A output paired with a 48V lithium bank delivers the fastest possible solar recharge.
The MC4 version suits 4WD expedition vehicles where the roof-mounted panel array has been pre-terminated in MC4 connectors. VE.Can support allows future integration with a full Victron GX system.
Superyachts and commercial marine vessels where MC4 is the standard panel connector benefit from direct connection to the 250/85 MC4, with CAN bus integration into the vessel's energy management system.
For large commercial off-grid installations using standard MC4-terminated solar panels in series strings, the 250/85 MC4 removes the need for additional wiring hardware while delivering 85A to a 48V battery bank.
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.
