The Victron SmartSolar MPPT 150/45 is a popular mid-size charge controller — 45A of charge current, 150V max PV input, and built-in Bluetooth. The 150V headroom supports residential-grade 60-cell and 72-cell panels in series strings, while 45A of charge current sizes well for 24V or 48V battery banks. Works on 12V, 24V, 36V, or 48V banks (auto-detect).
Solar array sizing
| Battery bank | Maximum solar array | Typical setup |
|---|---|---|
| 12V | ~650W | 3× 200W panels in series |
| 24V | ~1300W | 4× 350W residential panels |
| 48V | ~2600W | 6–8× residential panels in series strings |
Maximum PV open-circuit voltage: 150V.
