Victron SmartSolar MPPT 75/10 Charge Controller, Bluetooth Monitoring

The Victron SmartSolar MPPT 75/10 is Victron's smallest solar charge controller, sized for a single 100–145W panel on a 12V battery or up to 290W on 24V. It accepts up to 75V from your panels and delivers up to 10A of charge current, using Victron's ultra-fast maximum power point tracking to harvest more energy than a PWM controller, especially under passing clouds. Built-in Bluetooth lets you monitor and configure it from the VictronConnect app on your phone, and the VE.Direct port connects it to a Cerbo GX for VRM remote monitoring. It will even recover a fully discharged battery, charging from zero volts.

Key Specs:

• Max PV Input Voltage: 75V
• Max Charge Current: 10A
• Battery Compatibility: 12/24V (auto select)
• Nominal PV Power: 145W @ 12V, 290W @ 24V
• Max PV Short Circuit Current: 13A
• Load Output: 15A, with low-voltage disconnect
• Peak Efficiency: 98%
• Connectivity: Built-in Bluetooth (VictronConnect app), VE.Direct
• Dimensions: 3.9 x 4.4 x 1.6 in. (100 x 113 x 40 mm)
• Weight: 1.1 lbs (0.5 kg)

Sizing note: PV voltage must be at least 5V above battery voltage for the controller to start. A single 12V-class panel (about 18V Vmp) works on a 12V battery; a 24V battery needs two such panels in series.

A great fit for vans, small trailers, boats, and battery-maintainer setups running one small panel.
