The Victron Energy BlueSolar MPPT Charge Controller will charge a lower nominal voltage battery with a higher nominal voltage PV array. The controller will automatically adjust to 12V, 24V, or 48V nominal battery voltage. (software tool needed to select 36V)

Ultra-fast Maximum Power Point Tracking (MPPT)
Especially in the 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 MPPTs 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.
