The Victron SmartSolar MPPT 75/15 is a premium solar charge controller built to extract every last watt from your solar panels — even under partially shaded or overcast Australian conditions. Delivering up to 98% peak conversion efficiency via its ultra-fast maximum power point tracking algorithm, it handles up to 75V open-circuit PV voltage and provides a 15A charge current, supporting 12V systems up to 220W and 24V systems up to 440W. Built-in Bluetooth means instant wireless monitoring and full configuration via the free VictronConnect app, with no dongle required — ideal when your controller is mounted in a hard-to-reach compartment on your caravan or camper trailer.

Purpose-built for Australian off-grid adventures, the SmartSolar MPPT 75/15 is at home powering everything from rooftop solar on a caravan or motorhome to portable solar setups on a 4WD touring rig. It automatically detects 12V or 24V battery systems on first connection, and its adaptive 3-stage charging algorithm — bulk, absorption, and float — intelligently switches to suit the battery type, whether lithium LiFePO4, AGM, gel, EFB, or flooded lead-acid. The intelligent load output terminals with BatteryLife algorithm prevent over-discharge, while SafetyShield+ protection guards against reverse polarity, PV short-circuit, and over-temperature — giving you peace of mind whether you're parked up at a remote campsite or doing laps of the Simpson Desert.
