Solar charge controller Victron Energy SmartSolar MPPT 150/100 — 150V input, 100A output

Victron Energy SmartSolar MPPT 150/100 is a maximum power point tracking solar charge controller designed for photovoltaic systems with higher PV array voltages. With a permitted PV open-circuit voltage up to 150V and a continuous charging current up to 100A, this MPPT regulator maximizes energy harvest from solar panels and delivers stable, efficient charging for battery banks in residential and off-grid installations.

Advantages

The SmartSolar MPPT 150/100 provides accurate maximum power point tracking to increase energy yield from solar modules, especially under rapidly changing irradiance. Its high input voltage capability allows the use of long string arrays and reduces cable losses. Integrated charge regulation supports safe and reliable charging of lead‑acid and lithium battery systems, while built‑in protections guard against overcurrent and overheating. Bluetooth connectivity enables local monitoring and configuration via a mobile app.

How to use

Install the SmartSolar MPPT 150/100 according to the system design: connect the PV array to the PV input, the battery bank to the battery output, and ensure correct polarity and secure wiring. Place the unit where it can dissipate heat and maintain ambient ventilation. Configure battery type and charging parameters using the Bluetooth app or compatible configuration tools before commissioning. Verify PV open‑circuit voltage under no‑load conditions to ensure it does not exceed the 150 V rating.

Recommendations

Use appropriately sized DC cabling and fusing on both PV and battery circuits to minimize voltage drop and provide short‑circuit protection. Keep firmware updated and check configuration periodically. For systems with multiple MPPT controllers or parallel chargers, follow manufacturer guidance on grounding and system integration to ensure stable operation.
