Victron Energy BlueSolar MPPT 150/45

MPPT controller with an efficiency of over 98%. Fast MPPT controller for maximum energy yield. Fully programmable charging algorithm. Protection against overheating and short circuits. The algorithm maximizes energy output. Rated PV power, 12 V: 650 W. Rated PV power, 48 V: 2600 W. Especially in overcast conditions, when light intensity is constantly changing, an extremely fast MPPT controller can improve energy yield by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers. In the case of partial shading, there may be two or more maximum power points on the current-voltage curve. Conventional MPPTs tend to lock onto a local maximum power point, which may not be the optimal point. The device's innovative algorithm maximizes energy yield by locking onto the optimal maximum power point. Fully programmable charging algorithm as well as eight pre-programmed algorithms that can be selected via a rotary knob. Overheating protection and load reduction at high temperatures. Protection against PV short circuits and PV reverse polarity. PV backflow protection.
