The BlueSolar 75/50-MPPT charge controller is able to charge a lower nominal-voltage battery
from a higher nominal voltage PV array.
The controller will automatically adjust to a 12 or 24V 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-
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
