Features: Solar optimizers are mainly used to optimize the output power of solar photovoltaic panels to ensuring that the systems can work at maximums efficiency. Solar optimizer can significantly increase systems power generation by 5-25%. Photovoltaic optimizer is make of Plastic, which is wear resistant, enduring and corrosions-resistant. Just connecting the input end of the solar panel optimizer module to the output end of the photovoltaic module to convert the small current into a large current. The installation is convenient and simple. Using this optimizer can improve the conversion efficiency of solar energy, does not take up space, and is very suitable for home and courtyard use.
