1. automatically The controller only for lead acid battery Load indication the load LED lights when the load works If the load current is 1 25 times higher for 60 seconds or 1 5 times higher for 5 seconds than rated current of the controller the trouble LED flash slowly in red to show overload happened and the controller will shut down output When load short circuit happens the trouble LED will flash quickly then the controller will shut down its output When it happens please check if the load is properly connected Disconnect the load at fault and press the button it will resume its work in 30 seconds or in another day Work mode setting Way of setting press the on amp off button for 5 seconds long until the number on the LED screen begins to flash Press the button to choose a proper number When the number no longer flashes the setting is completed Press the button to check the value Light ON Light OFF control mode The load will start working when it gets dark until it gets bright or to the end of a setting time There will be a 10 mins delay before turning on the load in order to make sure if it really gets dark Light ON set time delay OFF mode the start process same with above Load will be closed after the setting time Setting time can be seen in time setting table If the load dose not work to set the time to occurrence of light control the light control priority Setting time can be seen in time setting table Comm2. Problems amp Troubleshooting Troubleshooting The charge LED indicator doesn t light in Check if the cable of solar panel connects properly green when sunlight gets the PV panel System over voltage or open circuit of the battery check if the battery connects to the system cable properly or the charging circuit damaged The load LED indicator light but there is Check if the load connects to the system properly no power output The charge LED indicator flash quickly The load LED indicator flash quickly and Check output circuit If the load short or over load there is no power output occurs remove the load and push the button and the controller will resume its work after 30 minutes The load LED indicator light slowly and Overload occurs remove some loads and push the there is no power output button again and the controller will resume its work after 30 minutes System state LED indicator flash in red Over discharge of the battery The controller will color and there is no power output resume its work after finishing charge of the battery Specifications Type Rated charge current Work voltage o12v 0o12 24V Auto 1 25 rated load current 60sec 1 5 rated loads current 5sec over load protection action gt 3 Rated load current short circuit protection action Over load short circuit protection Over voltage protection Work temperature Boost charge voltage Direct charge voltage Float charge volta

4. on controller mode The controller will work as a common controller no light and time control no ON and OFF delay time only has the else function Test mode It used for system debugging Only cancel the ON and OFF delay If no sunlight on PV panel it will turn on load at once If sunlight on PV panel it will turn off load at once Light Time modes when the number displayed on the LED is from 1 to 7 it is in Direct output mode Ten minutes after darkness falls the output switches on and remains on for the duration of the delay selected Time setting Light ON Light OFF Light ON 1 Hour delay OFF Light ON 7 Hours delay OFF ane Light ON 2 Hour delay OFF Light ON 8 Hours delay OFF ES Light ON 3 Hours delay OFF 9 Light ON 4 Hours delay OFF Light ON 5 Hours delay OFF
5. rdware part use flash memory to save all work control point instead of adjustable resistance to protect the control work point from going off as the adjustable resistance value is easily changed by temperature and vibration in order to make sure the control accuracy and reliability Operation easy to operate robust in design Controller Panel Indications pueunatge Indicator tor mee onoit System state LED V2 EA HOFF button Load state 4 LEDS Py BY LOAD System main circuit diagram Pott ee ee ee ee ee ee ee ee ee ee ee ee ee ee ee ee ee ee ee ee ee ee ae ee ee ee ee ee ee ee ee ee ee ee ee ee ee ee ee eee E MCU OUTPUT PROTECTION Eo amp POWER DRIVE OUTPUT Tl TE TEMP SENSOR inl CURRENT SEHSOR 51 a a BATTERY Installation a fix the controller in a certain place size of the installing hole Size 118 X 65X30 mm Length between installing holes 110 X 45 mm b Prepare wire Choose the plastic Copper wire Current density no more than 4A mm2 Cut the suitable length of wire and make it as shout as possible Peel off 5mm the plastic at the end of wire c Connect the wire to the battery port on the controller to the battery Pay attention to the pole of the connection If the pole is reverse it does not work It has the function of self protection and there is no any part will be damaged during this step but should correct this mistake d Connect the wire to the PV port on the con
6. troller to PV panel If the connection is correct and the PV panel gets the sunlight charging indicator will be light e Connect the load to the load port on the controller Attention the pole should be correct Attention during the installation if the voltage of the system is 24V you can not use the hands to touch any conductor in the system circuit in order to protect from electric shock Using Charge amp overpressure indication If the system is properly connected when sunlight shines on the PV panel the charge LED lights in green indicating the system is working in a good order PWM mode is applied in charging During the charging if over discharge has happened firstly the voltage for charging battery will be up to boost voltage and keep 10 mins then returns to direct voltage and keep 10 mins to activate battery lastly to float voltage and keep this state for the best state of battery These process is benefit to battery full charging and its life span Battery state when the battery voltage is in normal condition the state LED lights in green state LED flashes slowly in green when battery finishes its charge When the voltage of the battery is lower it will get in yellow color When the voltage goes down continuously to over discharge the System state LED will get in red color and turns off the output at the same time until the battery voltage recovers to over discharge return voltage the system will work again
