Regulador solar Victron SmartSolar MPPT 250/70-Tr — MPPT 250V, 70A

Victron SmartSolar MPPT 250/70-Tr is an MPPT solar charge controller designed to maximize energy harvest from photovoltaic arrays. With a maximum PV input voltage of 250 V and a charging current capability up to 70 A, this controller manages battery charging using MPPT tracking to increase efficiency compared with conventional controllers. It includes built‑in battery management and system protection functions to maintain battery health and support residential or commercial off‑grid and hybrid PV installations.

Advantages

The SmartSolar MPPT 250/70-Tr provides fast maximum power point tracking to extract the highest possible power from PV panels under varying irradiance and temperature conditions. Its high input voltage capability allows longer PV strings and reduces balance‑of‑system wiring losses. The controller integrates intelligent charging algorithms that adapt to lead‑acid and lithium battery chemistries and incorporates protective features such as overcurrent, overtemperature and reverse polarity protection. Bluetooth connectivity and compatibility with Victron monitoring tools simplify configuration and system monitoring.

Suitable for

• Residential off‑grid solar systems with battery storage
• Commercial or small industrial hybrid installations combining grid and PV
• Remote cabins, telecommunications sites and agricultural power systems
• Systems requiring high PV input voltage and up to 70 A battery charging

Key specifications

• Maximum PV input voltage: 250 V
• Maximum charging current: 70 A
• MPPT maximum power point tracking for optimized energy harvest
• Support for common battery chemistries with configurable charge profiles
• Built‑in system protection: overcurrent, overtemperature and reverse polarity safeguards
• Communication: Bluetooth support and compatibility with external monitoring platforms

How to use

Install the controller in a ventilated, dry location close to the battery bank and within recommended ambient temperature limits. Connect the PV array to the PV input, observing correct polarity and ensuring the array open‑circuit voltage does not exceed the 250 V limit. Connect the battery output to the battery bank using appropriately sized cables and fuses. Configure the charge profile for the battery chemistry via the Victron app or monitoring interface, and verify system status and telemetry after initial commissioning. Routine checks of connections, mounting, and firmware updates are recommended.

Recommendations

Use PV string configurations that keep the array open‑circuit voltage safely below the maximum input voltage under coldest expected conditions. Size DC cabling and protective fusing to handle the 70 A charging current and reduce voltage drop. For hybrid or grid‑interactive systems, ensure the overall system design complies with local regulations and coordinate settings between inverter, charger and the MPPT controller for optimal performance.
