MPPT controller with an efficiency of over 99%. Options for real-time data display: Color Control panel. Multiple maximum power points in partial shading. Innovative algorithm for optimal MPP. No cooling fan required. Eight pre-programmed charging algorithms. Protection class: IP43 (electronic components), IP22 (connection area). Especially under overcast skies, 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 cases of partial shading, there can be two or more maximum power points (MPP) on the current-voltage curve. Conventional MPPTs tend to lock onto a local MPP, which is not necessarily the optimal MPP. However, the innovative algorithm of the BlueSolar device always maximizes energy yield by adjusting to the optimal MPP. Fully programmable charging algorithm and eight pre-programmed algorithms that can be selected via a rotary knob. Overheating protection and load reduction at high temperatures. Protection against PV short circuit and PV reverse polarity. PV backflow protection. Compensation of constant and maintenance charging voltages depending on temperature.
