2,System Description
The controller for the solar power system, solar DC lamp system design, intelligent controller using the MCU. One-button touch switch, the completion of all operations and settings.With output short-circuit, output overload, anti-reverse polarity protection, battery full, over-discharge automatic shutdown, automatic recovery, all-protective measures, detailed solar status, battery status, load and various fault indication. MCU automatically on battery voltage, discharge current, temperature and other parameters related to battery capacity to sample the model through a dedicated algorithm,achieve discharge protection, temperature compensation, multi-function control,and the use of MCU control PWM way battery charging, multiple charging mode to resume the over charge and over discharge, normal direct charging, float charging, to ensure the battery work in the best condition, extend battery life.With a variety of operating modes, the output mode selection to meet user needs.
3, Install pole use
(1) Dimensions: 120X84X25(mm).
(2) Wire choice: Recommend the use of multi-strand insulated copper wire, the current density of less than 5A/mm2, wire length should be as short as possible to reduce line losses, since the maximum pressure line terminal access 2.5mm2 wire, cable head 10mm strip.
(3) Connected batteries: Note that +, - great, do not reverse. If the connection is correct, the battery indicator (BAT) light, can be key to check the status. Battery may not be normal.
(4) Connected photovoltaic cells: to connect the controller battery terminal coating, and then the other ends connected to the optical Ikegami, attention + - great, do not reverse, if there is sunshine, light (SOLAR) light. Otherwise, the need to check the connection on any.
(5) Load connection: connection to access the load the load on the controller output, attention + - very, not reverse, it would burn electrical appliances.
4,Help
Photovoltaic Battety and Overpressure Indicator .With sunlight to photovoltaic, SOLAR LED is solid green, green flash, it said the system over-voltage, processing, see troubleshooting content; SOLAR lights start charging. If the battery overdischarged, first to raise the charging voltage charge, and maintain for 10 minutes, and then straight down to charge pressure for 10 minutes to activate the battery, to avoid sulfide crystals, the final float voltage drop and keep floating voltage If there has not been released, will not have to upgrade charging to prevent battery water loss. The control process will achieve the best rechargeable battery or extend its effectiveness and to ensure life.
Battery Status Indicator. Constant green light: normal cells; Green slow flash: The battery is full; Orange Yellow: battery low; red: battery over-discharge, voltage too low, then the controller will automatically turn off output to alert users to replenish energy. When the battery voltage is restored to the normal range, it will automatically enable the output opening action.
Load Indicator. When the loading opening, the loading indicator (LOAD) Always. If the load current exceeds 1.25 times the rated controller rated current for 60 seconds, or load current exceeds 1.5 times the rated current of the controller 5 seconds, the slow red flash that overload, the controller will shut down output. When the load or load side of circuit fault occurs, the controller will immediately shut down the output, the red flash. When presents the above phenomenon, the user must inspect the load connection situation carefully, after the separation has the breakdown load, according to a pressed key, 30 seconds later the rehabilitation, or waits till the second day to be possible the normal work.
Key Setting Method. Click the button, digital tube lights, set the value observed in the 6 or 6. And 7 or 7. Displayed value will not change, other cases 1-5 or 1.-5. When the instructions before 3 seconds First Road Load (LOAD1) settings, three seconds after the second road load instructions (LOAD2) settings. Press the duration for 5 seconds, enter the work mode is set, the digital control (MODE) shows the current mode of flashing, release the button, each time converting a number, until the digital display corresponds to the mode, and stop buttons, and other digital control do not blink or complete the setup. Note: when setting LOAD2 with decimal output, without time to set LOAD1 output, in the 6 or 6. And 7 or 7. Is used, the two outputs are synchronous control, need to re-set 1-5 or 1 .- 5. pm before entering the two independent control of output.
5,Brief About Mode
Pure Light Control Mode: When there is no sun or light intensity dropped to start the point, the controller confirmed that the signal delay 10 minutes after the opening of the output; When the sun starts to rise when the intensity point and the controller output delay for 10 minutes to confirm close After the closure of the output signal.
The Light Controls+Time Delay Mode: The startup procedure controls with the pure light. The difference for the basis hypothesis's time closure output, supposes the definite opinion next table.
Universal Controller Mode: This mode cancellation of light control, time control, output delay function, press the (KEY) Dual output control
Debug Mode: Uses in the system debugging use, controls the pattern with the pure light to be the same, has only cancelled the judgment light signal 10min time delay, other function retention. The convenience when the installation and trial run checkout system installment accuracy
