Victron SmartSolar MPPT 250/70 is a 70 A solar charge controller with built‑in Bluetooth and ultrafast MPPT for PV systems up to 250 V.

• Ultrafast MPPT Technology: high‑speed MPPT gives the highest possible energy yield (efficiency >95%), up to ~30% more than PWM and ~10% more than slower MPPTs; strong low‑light performance.
• Inbuilt safety protection: comprehensive protection against PV short circuit, reverse polarity, overvoltage, overcurrent, reverse current and battery overvoltage; overheating monitored by internal temperature sensor with self‑diagnostic and high‑intensity LED fault indicators.
• Inbuilt Bluetooth & communications: built‑in Bluetooth for VictronConnect; RS232 / TTL (VE.Direct) for accessories; VE.Direct/USB cable support — live data transmission shows real‑time PV voltage, current and power plus battery data; data logs for the past 30 days.
• User‑defined battery charging algorithm & programmable relay: disable presets to use personalised charging parameters; programmable relay contacts (AC rating: 240 VAC / 4 A; DC rating: 4 A up to 35 VDC, 1 A up to 60 VDC) for alarms or remote control.
• Max PV and power ratings: maximum solar panel voltage 250 V; max PV power 1000W (12 V) / 2000W (24 V) / 3000W (36 V) / 4000W (48 V); maximum charge current 70 A.
• Optional extras and control: connection area for optional LCD display; optional MPPT control panel (sold separately); VE.Direct USB cable and supporting accessories available; user manual (VSSM250‑70) downloadable.
• Efficiency, consumption and approvals: efficiency >95%; self‑consumption <35 mA (12 V) / <20 mA (24 V); working temperature -30°C to +60°C (-22°F to +140°F); IEC/EN certified; enclosure IP43 (electronic components); Pollution Degree PD3.
• Mechanical and installation: dimensions 185 x 250 x 95 mm (7.28 x 9.84 x 3.74 in); weight 3 kg (6.61 lb); 4 x mounting holes (8 mm dia); includes self‑diagnostic and high‑intensity LED indicators.

Use with correctly rated PV arrays and batteries; consult the VSSM250‑70 user manual and VictronConnect for wiring, configuration and compatibility details.
