Description
The Victron BlueSolar MPPT 75/15 is a compact maximum power point tracking solar charge controller for 12V and 24V battery systems, sized for boats, campers and smaller off-grid installations. Its ultra-fast tracking algorithm holds the panel at its optimum operating point even as light levels change, harvesting up to 30 percent more energy than a PWM controller. Battery system voltage is recognised automatically on first connection.
This is the BlueSolar version, so it does not have Bluetooth built in. It is configured and monitored either over a wired VE.Direct connection to a GX device and the VRM portal, or wirelessly by adding a VE.Direct Bluetooth Smart dongle and the VictronConnect app. A short-circuit-proof load output with low-voltage disconnect, and full electronic protection against reverse polarity, over-temperature and output short circuit, keep installation safe and the battery protected.
