◆Highefficiency>98.2%
◆The solar module can track the maximum power point of photovoltaic batteries, and the maximum power point tracking accuracy is more than 99.5%.
◆The solar module adopts hot plugging technology. In a live power supply system, plugging in or plugging out the solar module will not generate sparks, or damage the terminals. It takes less than one minute to replace the solar module. When the solar module is inserted into the system, the system output voltage will not be disturbed.
◆Through the external controller, the output voltage of the solar module can be adjusted between 42V and 58V, and the adjustment accuracy is ±0.1V.
◆When the input voltage is larger than 152Vdc, the protection indicator (yellow) will be on,and the solar module will stop working. When a protection event occurs, the solar module will report it to the controller, which will handle the alarm.
◆The solar module has output over-voltage protection function, including Hardware over-voltage protection and software over-voltage protection. The hardware over-voltage protection point is 59.5. After the hardware over-voltage protection occurs, the solar module can only be manually started. The software over-voltage protection point can be set by the controller. The setting range is from 56V to 59V, which must be at least 0.5V higher than the output voltage. The factory default setting is 59V.
◆When the internal temperature exceeds the over temperature protection point owing to the reasons that the air inlet of the solar module is blocked, or the ambient temperature is too high, the protection indicator (yellow) on the panel will be on, and the solar module will stop working.
When an over temperature protection occurs, the solar module reports the alarm signal to the controller for corresponding handling. When the internal temperature of the solar module restore to normal value (the return difference is larger than 5°C), the solar module will resume working automatically, and the over temperature alarm will disappear.
◆When a communication failure occurs to the solar module, the protection indicator (yellow) on the panel blinks. The fault information will be reported to the controller. To protect the battery, the output voltage of the solar module becomes 54V (default value,which can be set by the controller) after the communication failure occurs. When the communication recovers, the solar module will resume normal operation automatically.
◆When a fan fails, the solar module will generate a fan failure alarm, the fault indicator (red) on the panel will blink, and the solar module stops output. After the failure is removed, the solar module can resume normal operation automatically.
