The CV-03 converter employs a DC/DC switching design that steps-up or down the input voltage (from hydrogenerator or solar panels) to a voltage compatible with batteries. This technology is also known as Buck/Boost design.
Concretelly, the converter is able to use a wide input from 7V to 50Vdc and transform it to regulated 14V or 28V with a 96% efficiency.
A MPPT (Maximum Power Point Tracking) algorithme is embedded into the converter to harvest the whole avaible energy which makes it very efficient both in hydro and solar mode.
According to the available energy, the converter charges the batteries with a 2-step method :
1- absorbtion mode at 14.3V or 28.6V during few hours
2- then floating mode at 13.8V or 27.6V
