1. 12V system the load automatically restore power However after the release occurred the battery voltage rises to over discharge return value 12 5V 12V system above of the time press button switch you can restore the load power by force to protect emergency user pay attention to the more than just voltage 12 5V 12 system works Page 3 of 42. 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 no Check if the load connects to the system properly 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 IN IN Nat Work voltage o12v 012 24V Auto Ce a protection gt 3 Rated load current short circuit protection action ip ee ees 14 6V x2 24V keep 10min charge return voltage 13 2v X 2 24V Temperature compensation 5mv C cell Boost charge Direct charge Float charge charge return voltage Lower voltage indicate 12 0V x2 24V Over di
3. ets 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 Ifthe 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 Page 2 of 4 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 automatically Load indication the load LED lights
4. scharge voltage 11 1V no load real time modified voltage by the discharge rate 2 24V Over discharge return voltage 12 6V x2 24V Control mode PWM charge mode modified discharge voltage by the discharge rate Page 2 of 4 SOLAR POWER CONTROLLER USER MANUAL Characteristics Control circuit use MCU and professional software as the control center to fulfill intelligent system control Charging mode use PWM high efficiency charging way Boost recovery and float charging auto work for battery long life Use temperature compensation High accuracy over discharging control by the discharging rate Over discharging control voltage modified by the battery discharging rate curve Self protection protection to 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 include fuse LED indication on system condition LED indicating the system of charging overcharge power full power low over discharge over load out short circuit load on off etc Industry level production standard wide temperature running area 35 C to 50 C No adjustable hardware 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
5. temperature and vibration in order to make sure the control accuracy and reliability Operation easy to operate robust in design Two output modes direct current output mode and 1HZ output mode Thel HZ output mode is very suitable for traffic caution light Controller Panel Indications PV charge Work mode LED 1 Digit set key System state ON OFF LED 2 Button Short circuit LED 3 4 PV Bat Load Page 3 of 4 System main circuit diagram pree eoo o o eee ee eee e e e e errr PWM E MCU OUTPUT PROTECTION OWER DRIVE Es amp POWER DRIVE OUTPUT Tl Q3 REVERSE CONNECTION TEMP SENSOR ml PROTECTION CIRCUIT 3 CURRENTSENSOR 1 BATTERY Installation a fix the controller in a certain place m size of the installing hole Size 140 x90 5 mm Length between installing holes 133 5x70 mm b Prepare wire Choose the plastic Copper wire Current density no more than 4A mm 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 controller to PV panel If the connection is correct and the PV panel g
6. 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 Load switching operation the controller power output is open after the default load under normal circumstances every time you press the button load the output that is a switch to change state When the load output is open the load indicator 4 Always When the load is off the load indicator 4 often destroyed when the load overload fault indictor light 3 Slow blinking when the load short circuit the fault set indicator 3 flash Overload or short circuit load controller will shut down output The first occurrence of the load short circuit output resumes automatically after 30 seconds if not discharged only manually restore output short circuit fault If reset overload short circuit protection load short circuit or discharge overload failure according to a key which returned to normal output Forced to return control over release release occurred after the battery voltage rises to put the return value over 13 1V
