PowerBoost

powerboost charge controller

 

The PowerBoost charge controller, developed specifically for PowerFilm’s semi-flexible crystalline and Rollable/Foldable Flexible a-Si panels, efficiently charges and maintains the health of lead-acid, Lithium-Ion, and other rechargeable battery systems. 


 

The proprietary, integrated PowerBoost charge controller provides a steady, regulated output to the connected battery or device (some battery banks are not compatible with panels that feature a PowerBoost charge controller). Different variations are available designed for specific panel sizes, output voltages, or battery configurations. The PowerBoost is compatible with low voltage inputs, allowing smaller panels to be built with uncut Sun Power Cells. This maintains high conversion efficiency of over 22%, while the cut cells used in traditional panels may drop to 17% or lower. Using Fixed Power Point Tracking, the PowerBoost has the performance of an MPPT controller while being a more cost-effective solution. Our charge controllers are specifically designed for use with solar and will not overcharge and reduce the life of the battery, a common problem with off-the-shelf PWM and MPPT three-stage charge controllers.
