Product Introduction

Colorful display with 4-key man-machine interface is more comprehensive, clearer, and convenient;

Wind charging ensures MPPT charging at low wind speed. And three-stage charging mode:MPPT charging; lifting charging; floating charging.

Solar three-stage charging mode:CC (constant current); lifting charging; floating charging.

Optional APP to inspect the controller operating parameters.

The controller has comprehensive protection functions such as overcharge, over discharge and overload etc.

Four battery types charging mode can be selected for operation: Lead-acid battery, Ternary lithium battery, Lithium iron phosphate, Custom ;

Product Highlights

The controller adopts color screen design, the display information is more comprehensive, the display interface is clearer, the controller supports WIFI module and GPRS module to expand and implement APP cloud monitoring(optional).

Application

The controller is suitable for solar off-grid system, automatically controls charging and discharging, and can be applied in communication base stations, household systems, street lighting systems, monitoring and other fields.

Indicator Function

The LED indicators on this controller showing

1) Red indicator:    in charging

2) Green indicator: output power from battery

The function definition is shown in the table below.

Protection function 

PV module polarity reverse connection

When the polarity of the PV module is reversed, the controller will not charge. The PV over and under voltage alarms can be viewed through APP. The controller will not be damaged. After re-wired correctly, the PV charging will resume normal operation.

PV under-voltage

When the PV array charging voltage is below the controller input voltage range, the controller stops charging the battery pack.

PV over-voltage

When the charging voltage of the PV array exceeds the input voltage range of the controller, the controller stops charging the battery pack, and the PV over-voltage alarm fault can be detected by the APP.

Solar charging over-current

When the PV array charging current exceeds the internal set value, the display will report IPV and ERROR flashing and stop charging;

Wind under-voltage

When the Wind charging voltage is lower than the controller input voltage range, the controller stops charging the battery pack.

Wind over-voltage

When the Wind charging voltage exceeds the unloading voltage value of the Wind, the controller turns on the unloading function, and the display shows that the unloading resistance icon lights up.

Battery polarity reverse

When the polarity of the battery is reversed, the controller fuse or other device may be damaged. It is strictly forbidden to terminate the battery.

Battery under-voltage

When the battery voltage is lower than the set under-voltage value, the display shows U under and ERROR flashing alarms, and the load output is automatically stopped to prevent the battery from being over-discharged and damaged.

Battery over-voltage

When the battery voltage reaches the over-voltage protection setting value, the display shows U over and ERROR flashing alarms, and automatically stops charging the battery to prevent the battery from being overcharged and damaged.

Night anti-reverse

At night, since the battery voltage is greater than the voltage of the solar, the automatic protection prevents the battery voltage from being discharged through solar.
