Our new model solar charge controller Win300-NBT come out,it is charging to battery adpot PWM technology,It is used on RV.Waterproof IP65.Common negative.There are four terminals.Contact panels and batterys,no load terminals.Users had better add the fuse when connecting.And the item support maximum 300W solar panel.As for battery type,AGM,GEL,WET,LiFePO4,Li-ion,LTO,Calcium.Users could adjust voltage by our bluetooth APP on the phone of Andriod.For LiFePO4,Li-ion and LTO battery,the constant voltage time is 1Hour.Pay attention that,1,for AGM,GEL,WET and Calcium battery,the maximum constant voltage time is 2Hours.If charging current<0.5A and holds for 1 min,the charging state will end.2,Only WET and Calcium batteries have equalization charging stage,2 hours maximum.Conditions for entering the equalization charging stage:If the battery voltage discharge below 12.1V or without equalization charging stage for 30 days.
The product 12V solar charge controller is shipped with a temperature sensor of length 80mm,If you need other components you need to purchase separately.
Temperature sensor,measures the temperature at the battery and uses this data for very accurate temperature compensation.The sensor is supplied with a 3m cable length that connects to the charge controller.The temperature sensor connected via interface 6.If the external temperature sensor is not connected or damaged,the internal temperature will be used for temperature compensation during charging.
Bluetooth communication in the PWM solar charge controller has the following characteristics:1,support Android mobile phone APP. 2,realize wireless monitoring functiion of solar controller.3,Use high performance,ultra-low power consumption Bluetooth dedicated chip.4,Adopt Bluetooth 4.2 and BLE technology5,communication distance up to 10m.
