Page 3: Safety Attention
1. Safety Attention: The input voltage is high, so please read the instructions before operation and please do not operate the controller before training. Warning: The operation is dangerous; please observe proper safety precautions before operation. Attention: The operation can damage or destroy equipment. Reminder: Suggestions and hints to the operator. -
Page 4: Charging Introduction
3.Charging introduction. The full name of MPPT is maximum power point tracking. It is an advanced charging algorithm which can detect the real-time power of the solar panel and the maximum point of the I-V curve that make the highest battery charging efficiency. Contrasted with the traditional PWM controller, an MPPT controller can adjust the maximum power point of the solar panel so that a larger charging current could be supplied. -

Page 13: Fault Code
When the PV power exceeds the rated power, controller will limit the PV power under the value of rated power so as to prevent the controller from being damaged, the controller will charge by limited current. 3. Battery reverse connection protection Battery reverse connection will not damage the controller but the system will stop working. -
