Victron SmartSolar MPPT 150/60-TR Charge Controller

The Victron SmartSolar MPPT 150/60-TR is a 60A solar charge controller accepting up to 150V of PV input, with screw terminals.

TR designates screw terminals, against the MC4 versions that plug directly into pre-terminated panel leads. Screw terminals suit an installation where the panel cable is being cut and run into the controller. MC4 suits panels used with their factory leads intact, and choosing wrongly means adapters or cut connectors.

Sixty amps at 12V is roughly 800 watts of array, which is a substantial installation. Working from the panels rather than picking a controller first is what avoids buying capacity the array will never produce.

Ultra-fast tracking continuously evaluates panel voltage and current to hold the array near its most productive point. That matters most under broken cloud, where conditions change faster than a slower controller can follow and output is lost each time it lags. Explore more solar charge controllers.
