Function

Explanation

1

Maximum Power Point Tracking

AdoptDC/DCTransforming Technology andMicrocontroller UnitThe technical realization of maximizing the power generation of solar panels.

2

Battery reverse polarity protection

The battery is connected to the controller with the polarity reversed.(In the absence of solar panels")It will not cause damage to the controller, and the controller will still operate normally after being connected correctly.

3

Preventing the battery from reverse discharge

After the solar battery group voltage is less than the battery voltage, the battery will not discharge to the solar battery group.

4

Solar Cell Array Reverse Polarity Protection

A solar battery array connected in reverse polarity to a controller will not damage the controller, and the controller will still function normally after being connected correctly.

6

Floating Charge Adjustable Voltage

Floating charge voltage can be adjusted by the user within a certain range.

7

Floating Charge Voltage Temperature Compensation

Based on the current measured battery temperature, 25Based on ℃, set the floating charge voltage for charging.-4mV/Cell"℃" is the symbol for Celsius temperature scale.compensation.

For12VBattery, Compensation Voltage"U=(t-25)*6*(-0.004)V"";

For24VBattery, Compensation VoltageU = (t - 25) * 12 * (-0.004)V"";

For48VBattery, Compensation VoltageU = (t - 25) * 24 * (-0.004)V"";

8

Increasing the charging voltage can be adjusted

The charging voltage can be adjusted by the user within a certain range.

9

Solar battery array input overpower deviates from the maximum power point

When the input power of the solar battery array exceeds the power that the controller can accept, the controller will shift the operating point of the solar battery array away from the maximum power point to prevent damage to itself. At this time, the controller charges the battery with the rated current.

10

Internal Overheat Protection

When the internal temperature sensor of the controller detects an excessive temperature, the controller will stop working to prevent damage to itself. Once the internal temperature of the controller has dropped to a certain value, it will automatically restart.

11

Temperature-controlled fan

When the internal temperature sensor of the controller detects a temperature above a certain value, the controller's cooling fan will be activated. Once the temperature drops below a certain value, the fan will turn off.

12

Solar Input Overvoltage Protection

When the solar input voltage exceeds the rated value, the controller will automatically protect and stop working until the input voltage returns to the normal range.

13

Remote monitoring function

Optional features, to achievePCView and modify the generator parameters and control parameters of the controller.

Fault Code

Fault Cause

Processing Method

E101

The solar battery pack voltage exceeds the maximum limit.

Check if the number of solar panels in series is too many.

E102

The controller's internal heat sink temperature is too high. The controller has stopped charging to prevent overheating damage. Once the internal temperature falls to a certain value, the controller will automatically begin charging again.

Check if the cooling holes of the controller are blocked or obstructed, and if the working environment temperature of the controller is too high.

E103

The battery voltage is lower than the undervoltage value, and there is no protective action.

E104

Controller internal heat sink temperature probe fault or not connected

E105

Battery voltage is too high, no protection action

Disconnect other charging devices to overcharge the battery.
