Couldn't load pickup availability
The Victron SmartSolar MPPT 150/70-Tr is the high-output mid-range charge controller — 70A of charge current, 150V max PV input, terminal-block ("Tr") connections. Sized for substantial 24V or 48V off-grid systems, large RV / marine solar arrays, or commercial backup-power installs. Built-in Bluetooth via VictronConnect.
The -Tr suffix indicates terminal-block connections (vs the -MC4 version, which has MC4 connectors pre-installed on the PV side).
Solar array sizing
| Battery bank | Maximum solar array | Typical setup |
|---|---|---|
| 12V | ~1000W | 3–4× 300W residential panels (rare config at 12V) |
| 24V | ~2000W | 6× 350W residential panels |
| 48V | ~4000W | 10–12× residential panels in series-parallel strings |
Maximum PV open-circuit voltage: 150V.
