Christmas decoration
I want to introduct something about photovoltaic (PV) controller. Our pv controller adopts the advaced electrical controlling technology. Through which sun energy converts into electricity and surplus electricity stores in the batterry.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 controllering in the solar applied system.In addition,our pv controller has advanced light control function to solar powerd lighting system,it automatically swithes on the lamp at night and swiches off at day time,it slao can swich off the lamp by the setting time,so this controller specially is suitable of controlling street light and pv power supply system.
