PV voltage up to 150 V
The BlueSolar MPPT 150/70 and 150/85 charge controllers will charge a lower nominal-voltage battery from a
higher nominal voltage PV array.
The controller will automatically adjust to a 12, 24, 36, or 48V nominal battery voltage.
Ultra-fast Maximum Power Point Tracking (MPPT)
Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller
will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to
slower MPPT controllers.
Advanced Maximum Power Point Detection in case of partial shading conditions
If partial shading occurs, two or more maximum power points may be present on the power-voltage curve.
Conventional MPPT’s tend to lock to a local MPP, which may not be the optimum MPP.
The innovative BlueSolar algorithm will always maximize energy harvest by locking to the optimum MPP.
