20A Solar Lighting Controller 20I EC

This 20I-EC 20A solar controller is Only For off-Grid PV Solar System.3 control modes to choose:

1.Charge Only

2.Light Control

3.Light and 15hours timer control(Settable)For 12V Pv System: 120W Solar Panel,12V Lead-acid Battery,21V for Max input VoltageFor 24V Pv System: 240W Solar Panel,24V Lead-acid Battery,42V for Max input VoltageThis solar charge controller is designed for solar DC power supply system. MCU and professional software are applied as the control center to fulfill intelligent system control. LED will indicate the working state. It`s easy to turn on and turn off output through manual operation. And there are two optional voltage modes, 12V and 24V.

Package including:1.1PCS Solar Contorller2.1PCS User ManualProtection:Overcharging protectionCan be used for all panelsOverdischarging protectionShort and Open Circuit protectionFull specification available if requiredFail Safe and cannot be damaged by accidental wiring mistakesAdvanced design with simple plug and play technology. No need for complicated adjustmentsFull LED status indication: State of Charge(SOC) Red-Flat Battery: Amber-Low charge: Green- good charge: Green Flashing- Full ChargeFeatures:MCU and professional software are used as the control center to fulfill intelligent system control, along with PWM high efficiency charging way. Boost, recovery and float charging auto work for battery long-life and with temperature compensation. It has high accuracy over discharging control by the discharging rate, over-discharging control voltage modified by the battery discharging rate curve. Our controller has the function of self protection from overload, outside and inside short circuit, reverse connection, thunder and lightning, PV panel reverse current, over charging and discharging etc. During the short circuit and overload protection, no any component will be damaged and need change, including fuse. The LED will indicate the working state of the system in charging, overcharging power full, power low, over-discharging, over load, out short circuit, load on/off and etc. Our products meet the industrial production standard with wide temperature running area -35℃ to +55℃.Rating:10I: 12 Volt or 12/24 Volt auto work, 10 Amps (for PV and load)20I: 12 Volt or 12/24 Volt auto work, 20 Amps (for PV and load)Equalisation voltage: 14.8VoltHigh voltage disconnect(HVD): 14.4VoltFloat voltage: 13.6VoltLow voltage disconnect(LVD) 11.1VoltLow voltage reconnect(LVR): 12.6VoltSelf-consumption: 6mA maximumTemperature compensation: -30mV/℃/12VTerminals: for wire sizes to 6mm2Temperature: -35℃ to +55℃LED indicator:Solar Panel LED:Green ON when solar is charging Battery.Green blink when the syetem over voltageBattery LED:Green ON when battery level in the right rangeGreen Slowly flashing when battery level fullYellow ON when battery level lowRED ON when loads cut off.LOAD LED:RED ON when the output is onRED slowly flashing when it`s over load(the load amps is 1.24 times of rated current for 60 seconds,or the load amps is 1.5 times of rated current for 5 seconds.)RED blink when the load is short -circuit.This controller has Light and Timer control FunctionLight control:When daylight starts to occur then the light source goes off. Meanwhile the Solar Panels will charge the batteries. when there is no sunlight the garden light will switch on.Time control:There is an eight hours time control,that means it will go off when the Lights automatically switch off after 0-15 hours.Lighting control Option1.Press the power switch for 5 seconds and select the desired LIGHTING CONTROL option.The LED is on,which confirmed you have selected the right one.2.The controller requires 10 munites of countinuous transiton values before it starts to work.These constraints avoid false transitions due to lighting or dark storm clouds.3.10 minutes off before the controller start to work
