PWM Solar Regulator 50A 12V 24V LED Blacklight Display Voltage Settable for Charging Battery Protection Solar Charge Controller

Item Descrption
The controller is a new series of intelligent,multi-purpose solar charge controllers.Its innovative structured design makes it easy to install and more reliable to use.Optimized charging and discharging management enables the service life of batteries to be greatly boosted.Meanwhile,more system symbols can be displayed in bigger LCD interface.Vivid symbols can show the working status of the system and relevant parameters can be fully displayed.What’s more ,intelligent control of LED backlight makes it possible to see all symbols and parameters clearly even in the dim light conditions.Various control parameters can be flexibly set to fully meet your various application requirements .
Features
1. 3-stage charging
Bulk charge stage:
Bulk charge is the first stage in the charging process.In Bulk charging stage,the controller will deliver 100% of available solar power to recharge the battery and will trying to get the battery voltage up to the Absorb Voltage Setting.
Absorption Charge:
When the battery voltage has recharged to the Absorption voltage setting ,constant-voltage regulation is used to maintain battery voltage at the Absorption setpoint.This prevent heating and excessive battery gassing.The battery is allowed to come to full state of charge at the Absorption voltage setpoint.The absorb timer start to the count and the controller stays in absorb until the Absorb Timer counts up to absorb time.
Float Charge:
After the battery is fully charged in the Absorption stage,the controller reduces the battery voltage to the Float voltage setpoint.When the battery is fully recharged ,there can be no more chemical reactions and all the charging current is turned into heat and gassing.The float stage provides a very low rate of maintenance charging while reducing the heating and gassing of a fully charged battery.The purpose of float is to prrotect the battery from long-term overcharge.Once in float stage ,loads can continue to draw power from the battery .In the event that the system load exceed the solar charge current ,the controller will no longer be able to maintain the battery at the float setpoint.Should the battery voltage remain below the float setpoint for a cumulative 30 minute period ,the controller will exit float stage and return to Bulk charging.
2.Presets parameters for 3 different types of battery
Standard charging parameters fot “GEL”, “Sealed” and “Flooded”battery are preset.Moreover,a set of user-defined charging parameters are also available,and is shown as follow:
Battery type Float voltage Absorb voltage Absorb time
GEL 13.8V 14.0V 2H
Sealed 13.8V 14.4V 2H
Flood 13.5V 14.6V 2H
User 13.8V 14.4V 2H

Note:If the battery type is “GEL”,“Sealed”or “Flooded”,above parameters are preset and you can’t set them.

3.Auto-detect the battery voltage or locked to a fixed voltage .
The “AUTO”setting allows the controller to detect the system voltage automatically on start up and the detected system voltage will never be changed during operation.The auto detect feature should only be used in situations where the system voltage is unknown ahead of time or in systems where the system voltage may charge periodically
4.Adjustable charging voltage
When”User”battery type is selected,float voltage can be adjusted within certain range,default value is 13.7v(for 12v battery).Absorption voltage can be adjusted in a certain range,and the default value is 14.4v(for 12v battery).
5.Temperature compensation for charging voltage.
-4mV/Cell/°C temperature compensation will be applied to the preset voltage for Float charge,absorption charge according to the present battery voltage measured by the controller,for 12v battery,the compensation voltage U12=(t-25)*6*(-0.004)v.You can deduct the other voltage level like this.
6.Various control modes for load.
There are four control modes for load.they are normal control mode(0),light control on and delayed off mode(1),light control on and delayed off and one hour before dawn(2),light control mode(3).the delayed duration can be 1-24h.Following are the working introduction for each mode.


Event
Load Mode Dark End of delay time 1h before dawn dawn
0 -- -- -- --
1 Load on Load off -- Load off
2 Load on Load off Load on Load off
3 Load on -- -- Load off

Note: The load will not be on if there is over-current, low voltage of battery or high voltage of battery. Load will be shutdown under any circumstances like short-circuit, over-current, low or high voltage of battery. For normal controlling mode, load can only be turned on again when you turn on it by yourself. Load will recover to working normally after clearing the failures like battery low voltage protection, battery high voltage protection, load over-current protection and load short-circuit protection. For the mode 1,2,3, load will be turned on automatically when coming cross a load on event even the load have been turned off by person before. Load will be turned off automatically when coming cross a load off event even you have been turned on the load by person before. If the controller has any of the following situation like battery low voltage protection, battery high voltage protection, load over-current protection and load short-circuit protection, it will make a judgment for turning on and off logic and then decide when to on or off the load.
7. Statistical data of generated energy and consumed energy.
The controller will calculate the following data everyday: total generated Ampere hours, total used Ampere hours by load.
8.Communication function.
This is an optional function. If you need this function, please let us know before your order is placed. You can view all relevant data through computer’s COM port and the parameters like float charge voltage , low disconnect voltage, low reconnect voltage can be set. There are other functions like turning on/off the load by remote control and unlock the protection. RS232 or RS485 bus is provided. The communication ID range is from 1-99. For more information about communication protocol, please contact us or consult our dealers.
9.Protection for reversed connection of battery.
If the battery is connected with controller in reversed polarity(not connected with solar panel), controller will not damaged and will work as normal when correctly connected.
10. Protection for reversed connection of solar panel.
If the solar panel is connected with controller in reversed polarity, controller will not be damaged and will work as normal when correctly connected.
11. Protection for reverse-discharge of battery.
Controllers are able to protect battery from reversed discharging to solar panel at night.
12. Protection for input over-current from solar panel.
Controllers will stop charging when excess current is detected from the solar panel, and repower automatically after 2 minutes.
13. Over-current protection for load.
The load will be turned off when the output current of the load exceeds its rated current for a while, and then be turned on automatically after 20 minutes.
14. Short circuit protection for load.
Controller will enter protection state when the load is detected to be short circuit, and repower automatically after 2 minutes.
15. Under-voltage protection for battery.
Controller will turn off the load when the battery voltage is lower than the value preset for under- voltage protection, and turn on the load when the battery voltage reached the value preset for under- voltage reconnect. The value for under- voltage protection and under- voltage reconnect can be set by users in a certain range.
16. Over- voltage protection for battery.
Controller will turn off the load when the battery voltage is higher than the value preset for over- voltage protection, and turn on the load when the battery voltage is 1V lower than the value preset for over- voltage protection.
