Products Introduction
Our photovoltaic (PV) controller adopts the advanced electrical controlling technology, through which sun energy converts into electricity and surplus electricity stores in the battery. Comparing to normal PV controller in the market, our PV controller has additional charge function with small current, that means when system reaches overcharge protection voltage, our PV controller adopts small current for charging, in this way it can improve the utilization factor of solar cells and extend the lifetime of battery. Therefore our PV controller is an ideal controller for charge/discharge controlling in the solar applied system. In addition, our PV controller has advanced light control function to solar powered lighting system, it automatically switches on the lamp at night and switches off at day time, also can switch off the lamp by the setting time, so this controller specially is suitable for controlling street light and PV power supply system.
