Photovoltaic controller and inverter inspection
1. the operation and use of the photovoltaic controller and inverter should be carried out in strict accordance with the requirements and regulations of the instruction manual. before starting the machine, check whether the input voltage is normal; when operating, pay attention to whether the sequence of switching on and off is correct, and whether the indications of the meters and indicator lamps are normal.
2. the controller and inverter will generally enter automatic protection and stop working when there is a circuit break, overcurrent, overvoltage, overheating and other faults. once these devices are shut down, do not turn them on immediately, find out the cause and repair them before turning them on again.
3. there is high voltage in the inverter case or cabinet, the operator is generally not allowed to open the case or cabinet, and the cabinet door should be locked normally.
4. when the ambient temperature exceeds 30°c, cooling measures should be taken to prevent equipment failure and prolong the service life of the equipment. frequently check whether the temperature, sound, and smell inside the machine are abnormal.
5. strictly check whether the wiring of each part of the controller and inverter is loose (such as fuse, fan, power module, input and output terminals, and grounding, etc.). if the wiring is loose, repair it immediately.
