A charge controller, or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged.

Features:


Three system voltage configuration : 12V, 24V or 12V/24V auto work
·High efficiency PWM charging with temperature compensation
·3 LEDs shows PV charging, battery and load status
·External temperature sensor interface
·RS-485 bus communication
·Open standard Modbus communication protocol
·Software update function
·Diversified load control modes : Manual, Light ON/OFF, Light ON+ Timer, Time Control
·Battery type selection: Gel, sealed, flooded and User type
·Real-time monitor
·Programmable parameters
·LVD  or SOC load disconnect function
·Energy statistics function

 

Electronic Protections:

 

·PV short circuit
·PV reverse polarity
·Battery overcharge
·Battery over discharge

Q:What is the meaning of the 30A solar controller?
This 30A proves that the controller has a maximum current of 30A.
Q:Solar controller one machine how
First of all, if you are using a multifunctional VRV system, triple the (air conditioning, to warm, hot water) together, then connect the solar energy, solar energy is auxiliary equipment, can not be set as the main control equipment. Finally, I would like to ask, your one machine is a computer or I said one machine
Q:How to debug a solar street light controller
Press the button for more than 3s digital tube began to flash, the system into the adjustment mode, release the button, each press a button, digital tube digital will change a number until the digital display of the number of users from the table selected mode corresponding The number of so far, such as digital tube to stop flashing or press the button more than 3s to complete the set.
Q:What is the system voltage of the solar controller?
The system voltage is the voltage you use the battery, such as 12V or 24V. According to your overall configuration, if your battery is a working voltage of 18V, then the system voltage can only use 12V, 36V is used on the 24V.
Q:What are the solar controller models?
You that the controller is the manufacturer, go to their website under the instructions can be
Q:Solar water heater controller power screen is not displayed
Probably the relay is burned out
Q:Solar water heater all intelligent controller how to install
Different manufacturers are not the same, you can call to contact after-sales processing
Q:Solar controller water level display is not correct how to do
Re-adjust the water level to control, choose their own water.
Q:How the solar panels with the controller
Light control on + delay off - open delay + light control off the double time mode: the work process is open when the dark load (light control on), delay to set the first time after the closure of the load, turn off the load After the day until the day before the set of the second time to open the load again, to the dawn when the load off (light control off), the night when the load is closed to save power. The controller uses fuzzy control to automatically identify and effectively correct the darkness to the dawn of the entire night time, that is, according to the length of the night to automatically adjust the time to close the load at night to ensure that the load only in the dark and before dawn Set the time period to open, the other time is closed.
Q:Solar controller use
The biggest use of solar controllers is to protect the battery
