7. Provide industrial generic RS232 communication interface, the user can design PC communication software, also can buy the company developed the upper machine communication accessories.

Perfect Protect function:

1.  PV array short circuit:PV array input short circuit, when it solved, the controller will continue to charge the battery automatic.

2.  Reverse connection of PV modules:When reverse connection of PV modules, the controller will not damaged. After you modify the wrong connection, the controller will continues to work safety.

3.  Reverse connection of battery:When reverse connection of battery, the controller will not damaged. After you modify the wrong connection, the controller will continues to work safety.

4.  Sensor off: When the current-sensor-wire off, it will affect the current display, but it does not affect the normal charging and discharging of the system.

5.  High voltage surges:This controller have great protection for smaller energy with high voltage surges. At lighting frequently areas, we suggest to install external arrester for the controller.

Operating

I. LCD Display

1- LCD Display: Display system operation parameter

2- Charge indicator: Indicate the charging status

3- Battery indicator light: Indicate the battery voltage and discharge state

4- Set the button: Press this button to enter setup interface or change the Settings.

5- "↑"button:  Click this button add a page up or figures

6- "↓" button: Press the page up or number minus one

7- Exit button:  Under the set interface to browse interface, press this key to exit the setup interface does not save the Settings data when power supply drop

II.  LCD initial interface introduced (default during the day)

1.  Two ">>>" represent the charging and discharging, for charging, have the current will show effect, when there is no current or current is very small, the label will disappear;For discharge, when the battery is in a state of undervoltage, flashing the overall effect, when the battery is in good state, according to static effect, marking can pick up the load, after loading,if there are current,will display effect.

III.  Battery Charging Status

·Fast Charging Gradation:

In fast charging gradation, solar controller will come into direct charge mode if voltage of battery cannot reach re-made full charge values.

·Fast Charging Gradation:

In fast charging gradation, solar controller will come into direct charge mode if voltage of battery cannot reach re-made full charge values.

·Boost Charging Gradation:

Solar controller will adjust battery voltage continuously to maintain boost charge setting point when battery voltage reached setting values.

It prevents battery from product gas and become too hot.

Battery boost charging time keeps about 120 minutes, and then solar controller will enter into float charge statues.

Solar controller will come into boost charge status while it identify battery isn’t in over-discharge and over-load status every time.

·Float Charging Gradation:

Solar controller will enter into float charging status after battery finished boost charge gradation.
